Let’s get technical and Meet The Experts at DTW 2019

So you went to Vegas on (airquotes) a work trip yeah?

What on earth was I doing in Vegas last week? My friends and family think I’m off on a holiday without my wife and stare blankly in disbelief when I say i was there for work. Anyone in the Tech Conference business knows about Dell Technologies World, however I still need to be able to elevator pitch exactly what my role was for the week. The answer essentially? I was working the Meet The Experts Zone for Hyperconverged solutions and delivering Design Sessions on Smart Fabrics and 2-Node for VxRail. Sound interesting? If you want to hear a little more I give you two options. Listen to the podcast myself and Paul Wynne recorded with Barry Coombs Live at the show, or read on and Ill try and make it real for you.

Meet The Experts and Hands on Labs

The Hands on Labs area needs little introduction. Want to get Hands-On with the solutions sold by Dell Technologies? The Demo Center team have taken their Demo catalog on the road to Vegas. You can choose from the extensive catalog and sit down at a station and follow a guide or explore a new technology at your own pace. This is a pretty amazing capability that is also available post-show and the team that bring it all together are some of the hardest working and darn clever people I have met at DT.

If you look to the left of the HOL zone entrance, you cant help but notice a newly re-designed and well branded Meet The Experts area developed by the Customer Solutions Center team. Here there exist two offerings the Meet The Experts “Guru” Bar and the Design Sessions rooms.

Meet The Experts “Guru Bar”

On the far wall facing the HOL zone you can see 6 high tables with what looks like bartenders waiting for customers to place orders. The tables are made of whiteboard and the bartenders are holding pens serving knowledge not cocktails. This area is first come first served and staffed round the clock by various experts across topics like Storage, Data Protection, Hyperconverged, Multi-Cloud, VDI, IOT, A.I. and Surveillance solutions. Most of the time the sessions were quick and the customers questions were deeper and technical in nature. The experts had no idea what or who would walk up looking for info so the atmosphere was pretty electric and fast-paced.

MTE Design Session Rooms

In addition to the adhoc sessions at the Bar, several of the Customer Solutions Center experts designed a powerpoint-free session for up to 12 people that could be booked in advance. These sessions were focused around specific topics and leveraged a digital whiteboard. The sessions were interactive because the audience was small and the presenters were able to answer questions from the customers in attendance. Quite often the questions would dictate the direction the session would take, rather than following a set path.

So how did we do?

The team that designed the area put a lot of thought into creating an experience that was a living breathing example of what happens 365 days a year across the Customer Solutions Centers. The data is still flowing in but by all accounts we smashed last years numbers and the feedback we are hearing from all across the organization is that the conversations were deeper, more focused and better serving to Dell Technologies customers right across the board. Personally I am well proud to have played a small part in the success of the event and I am excited to see where the brand and vision takes us.

This all looks very familiar.

It isn’t by chance that the Meet The Experts “Guru Bar” has a very familiar look and feel to VMworld Barcelona. I wrote about my experience there back in November. I came home from that event, wrote up a report, and gave my opinion to anyone that would listen. We had to do something similar for Dell Technologies World 2019. In past years we did have a similar area, but the brand wasn’t as strong and the area didn’t “catch the eye”. I have to admit our management team went leaps and bounds above expectations to create a powerful presence at the show that anyone working there could be proud of being a part of!

Experts from across Dell Technologies always meet at Meet The Experts Zone

Look after your Mental Health: Start an OK Club

Are you feeling overwhelmed?

My mind is still spinning down post Dell Technologies World 2019 and I’m facing the challenge anyone that attends work conferences must be facing. Do I keep the momentum from the crazy full-on world of Vegas conference life and capture ALL my great thoughts, or do i pause and let my body finally recharge. There is a temptation to fight the bodies natural routines, and to artificially extend creative time. This could push me into a danger zone that might have after effects on my own mental health.

Pausing is not quitting.

I start to get worried about this decision and the fear of missing out starts to overwhelm me. I want to do right by myself and start to recharge, but I see other peers that are more successful and i think what would they do? Quitters never win right?

As I rush off to the airport with this in mind, i bring the notepad and pen with me just in case. I guess that’s my decision made. Heading for the lobby I discover by pure chance a close friend and colleague is heading home at the same time so we agree to meet and share an Uber to the airport. On the ride we reminisce on the great times of the past week and as we chat we discover we are both wrestling the same problem.

It’s OK to Talk.

My friend reveals that recently he faced some serious work related issues that thankfully he is well past, but that he struggled alone for almost a year and it badly affected health and happiness. I was shocked, I didn’t realize anything was amiss. He looked like he was busy sure, but I thought he was taking it all in stride. When I told him that I didn’t know and I was sorry for not noticing he admitted he may have put up a facade. As we talked we wondered if anyone else in our field that we knew could be going through the same suffering in silence torture? How could we break the cycle? How could we prevent the problem starting with some preventative measures? What even are they?

Start an OK Club for Mental Health.

So we decided to start an OK Club. This is a safe place to reach out and be able to talk openly, a place of trust and honesty. This is an agreement to look out for one another, a buddy system similar to SCUBA diving. Our OK Club has only 3 members for now, someday there may be a need for more, but 3 is good start. Nothing prevents you from being in more than one club either, just make sure you are not just supporting others, but are also supported by others yourself.

I went googling for some info around Mens Mental Health and came across #AndysMansClub. It is an eerily similar concept that started after a tragic young man committed suicide. They even made a logo related to the OK signal and used the #ItsOkToTalk. Even after being featured in TheLadBible and being promoted by some famous people on twitter. I can honestly say i had never heard of it.

I am glad I know about it now, and I’m glad I have the support of an OK club. Look out for each other, form one, join one. If you don’t have someone close to you that you can open to, please find someone

Vegas Tips and Tricks, Dell Tech World 2019

Are you going to @DellTechWorld ? Interested in #VxRail or SmartFabric networking? Register for a session and we can have a chat! https://buff.ly/2DnzECu 

Its vendor conference season again, are your ready? Accommodation booked, event ticket snagged and you have your aisle seat reserved on the flight, now what else do you need…

Preparing before you go.

Don’t keep it a secret that you are going to the conference! OK you don’t have to brag about it on social, especially if your security conscious and your home is going to be empty, but make sure your network knows you are going. This is a chance to plan ahead and make appointments with people you want to target for face time. You may only see some of these people at events once or twice a year, make the most of it. Don’t just ask them to visit you at a booth, make the effort to seek them out.

Set yourself reminders of lists of people you want to meet, seek out their sessions if they are speakers or find out where they will be and doorstep them! I always keep an ear out for recommended sessions or good speakers and try and see them. Support others that are going to the event, they will support you back.

Events like VMworld or DTW always have intimate sessions with smaller audiences. These are a great opportunity to get to make eye contact or even speak with a presenter after the session. This is much harder to do at a keynote. In Barcelona after VMworld I blogged about the Expert Sessions that were bookable. Amazing presenters and tiny audiences. I even found myself in a session where I was the only person that turned up!

Hang around the Podcast tables and see if you can get a spot. Step out of your comfort zone and show everyone you have something to say. If you are worried about content, try something easy like a Tech Confession style podcast, the content is you!

What’s in the phone?

Make sure you have loaded up the essential phone apps for the event, you will not want to lug around a laptop just to check a schedule or confirm a flight.

  • Dell Tech World app is up, be sure to install it and nail down your schedule.
  • Google Maps. This is a must IMHO. Visiting a new city for the event? Download the offline map and get tips and advice from locals on the best places to visit before or after the event kicks into high gear.
  • Travel Apps. All major airlines, Uber or Lyft or a local service. I use TripIt linked to my gmail, handy for itinerary and travel planning. I am trying out Google Trips for the first time this event, good so far!
  • Expenses? Amex and Concur have good apps. Nothing worse than having to dig thru a pile of receipts when you get home. Concur has gotten really smart at creating entries directly from images of receipts.
  • Communications. Nothing worse than being on your own at an event when you want to meet up with friends or contacts. Plan ahead and create WhatsApp groups or use Slack/Teams to reconnect with people. This year we are trying out WhenIWork app that looks pretty powerful, and includes a scheduler for team members.
  • Podcast! No better place to collect new podcasts in your catcher, I use Podcast Addict. You can also try and start your own one using the Anchor app, maybe a roving reporter style?

What’s in the suitcase?

Before you pack you have checked the local weather right? Use YR app and make sure you are covered for all possible seasons as well as a flexible wardrobe for business and casual events. Have you got the right shoes? If you don’t have a comfortable pair, rush out now and buy some. You still have time to get them broken in BEFORE you put them on in Vegas. Dress shoes for the customer dinners, black shoes for booth duty and runners for downtime. I over-pack underwear and socks, never want to run out. Day Shirt and Evening shirt please, let the event dictate the style. Don’t forget to pack a big enough bag for the return trip, especially if you are into collecting swag.

When in Vegas…

It gets harder and harder to snag a ticket if you don’t have a job to do, so more than likely you have some sort of responsibility while you are at the vent. Hopefully in your busy schedule you have been allowed some free time, use it wisely. Don’t just swag hunt, make sure you network, seek out new technology, use the creative space to bounce ideas off others.

There are other things you can do, other than work and attend some sessions. Get a headshot. There is always at least one stand setup to offer free headshots. Plan ahead and where or bring a suitable shirt/jacket/tie/dress combo that will look good. If you fancy something different and are a little shy, try and find a caricature artist that will cartoonize your headshot.

Have you planned for some alone time? Big conferences can be overwhelming, especially for an introvert. Make sure you get some time to empty the head, go for run or hit the gym or just lie down for 20 minutes. Recharge the mind so you can get back in the game.

Go on be social.

There is a temptation to try and attend every social gathering scheduled. Sometimes you will find yourself triple booked as all the evening events seem to be on at the same time. Stick to water and make as many appearances as you can, build that network. But in this section I am not talking about pubs or clubs, I mean of course social media. Even if you aren’t a social ninja and the thoughts of tweeting selfies makes you breakout in hives, i want you to step out of your comfort zone and leverage at least some of these apps.

Buffer. There are multiple tools out there now that will allow you to schedule tweets. Take time to plan ahead and write some before the event. You don’t want to have your head in a phone app when you could be meeting and greeting.

Twitter. This can be a great way to find people as well as let people find you. Find out your conference official hashtags and include them in your tweets. It doesnt take much effort to get up on the Social Media wall of fame and its great for exposure as people walk past. Threaded tweets are great for events, consider using them when you have a lot to say.

LinkedIn. If you have neglected your profile here, now is the time to polish it up. You will be looked up, you will be added by people you meet. Do you have a good title? A clear elevator pitch? LinkedIn is never finished, you can always improve areas of your profile.

The key to surviving Vegas.

Stay hydrated is the most obvious one. Bring a reusable water bottle. Dell Technologies is again this year providing water stations to get a fill up and to conserve plastic waste. The air is so dry there you will literally get Vegas throat or conference cough. Every morning, when you shower, plug the drain and fill up the tub with water, leave it humidify while you are out! At night, take a towel, soak it in the tub and hang it over the air-con vent. Trust me you will sleep better. (credit to @lost_signal for this tip, saved my 1st Vegas).

Even if you don’t make a conscious effort to hit the gym or go for an early morning run, you will do enough walking to burn a LOT of calories. Be smart when you eat the free food provided. There is ALWAYS a healthier option to choose, don’t just fill up on sweets and meat!

Every step you take, and every glass of water you drink will mean you can safely enjoy at least one great meal each day. Do like my good friends @Josephcorreia @livfitz and @VDIallStar  … ignore the travelators and elevators and take the stairs!

How to deploy the SmartFabric OMNI plugin in VMware vSphere Step 3

Step 1: Enable SmartFabric Services on the ToR Switch

Step 2: Deploy VxRail Cluster incl. ToR with VxRail Manager

Step 3: Deploy the SmartFabric OMNI plugin in VMware vSphere

Next Blog : Step 4: Virtualization engineer controls Day 2 Ops for the Full Stack

Installing the SmartFabric OMNI plugin

At this point we have already run the first two steps to get SmartFabric installed, our Switches have SmartFabric services enabled and the VxRail Manager Gui deployment has automatically configured the switch and disabled the CLI. Now we will add the Open Manage Network Integration or SmartFabric OMNI plugin to vSphere, giving the virtualization engineer full visibility and control of the dedicated HCI switch fabric.

Download the OMNI plugin VM

We begin by deploying the OMNI VM ova, which is available from VMware Solution Exchange here. It seems to bounce you now to the Dell Support site where you can get the latest version here. As of June 2019 the latest version is 1.1.18.

Deploy the OVA

These steps are straightforward. Isn’t great that we can do the OVA deployment thru the HTML5 interface? Be sure to match up the source and destination networks correctly at Step 7 in the process. Later on we will configure an ipv4 address on vCenter network and enable ipv6 on the MGMT network.

Power on the VM and connect to a console on the OMNI vm. You need to establish a password here for the admin user. The default username and default password is setup as admin / admin.

Configure the OMNI appliance

Since this is a first run deployment, we are going to select option “0. Full Setup” at the Menu. As you can see you can re-run and do other admin tasks later if required from this interface.

Before we active the first connection, we will setup the Profile name “vCenter Server Network” and assign a valid ipv4 address for the OMNI VM here.

The second connection is for ipv6 discovery on the VxRail Management network, no ipv4 address needed here.

Be sure to activate both networks on the last screen.

You will be prompted at the CLI again for NTP, SSL Cert, the appliance ip address, FQDN for VCSA, VC Username and Password, and finally the OMNI ip for REST and REST username and password.

Log in and out of vSphere and the OMNI plugin will appear.

How to deploy SmartFabric for VxRail Step 2

Step 1: Enable SmartFabric Services on the ToR Switch

Step 2: Deploy SmartFabric VxRail Cluster incl. ToR with VxRail Manager

      • Connect VxRail nodes to deploy SmartFabric enabled Switches
      • Power on first 4 VxRail nodes
      • Deploy SmartFabric VxRail thru the VxRail Manager GUI
      • Sit Back and Relax while VxRail Manager fully automates Bring Up of the entire Hyperconverged Stack (Compute, Storage AND the Network!)

Next Blog: Step 3: Deploy the OMNI plugin in VMware vSphere

Step 4: Virtualization engineer controls Day 2 Ops for the Full Stack

Beginning the VxRail GUI deployment

Connect the VxRail nodes to deploy SmartFabric enabled switches. Power on the nodes. Connect the laptop to the first port (port 1 only!) in the SFS switch. This is the “jump port” and will allow access to the default ip address [https://192.168.10.200] of the VxRail Manager VM. The VxRail Manager VM is already deployed in the appliances in factory.

VxRail Manager GUI install
The Vxrail Manager GUI interface used to deploy a new cluster.

VxRail will deploy SmartFabric now

Since VxRail version 4.7.100 there is now the ability for the GUI driven VxRail Manager install to detect Dell EMC SmartFabric enabled switches. This automates configuration of the switches during the full stack deployment.

deploy SmartFabric
Here we can see that VxRail Manager has detected a Smart Fabric is available to configure thru VLAN 3939 the discovery VLAN for nodes and switches.

Setup the REST user to deploy SmartFabric

When the installer selects to deploy SmartFabric switches the next step will be to configure the Rest User account on the SFS enabled switch. If its a first run, a new password will be created. If you are setting up a second VxRail cluster into an existing SmartFabric, then the current password will be requested. The Rest User account will be documented in the Pre-Install Checklist by the installer.

Setting REST User password
The REST user account needs a password set.

New option to choose 2-Node cluster

The ability to deploy 2-node clusters is now an option with VxRail 4.7 versions. The GUI install gives you a choice for 2-Node here. For all other VxRail deployments the default option is selected.

New 2 node VxRail option during GUI install
You need at least 3 or 4 nodes to start the Smart Fabric node setup.

The initial cluster deployment needs to be 3 or 4 nodes. Normally the node with lowest serial number wins the VxRail Manager election process. This is signified by the small “house” icon. If you don’t see all the powered on nodes, try a reboot of the missing node and wait. It should be detected by ipv6 multicast using the loudmouth service on the discovery VLAN 3939.

VxRail node discovery

Automate the build with JSON

Remember we use the Pre-Install checklist is used to capture all the required information to make a VxRail deployment in a customer Datacenter go perfectly. It can also be used to generate a JSON file to help eliminate human error during the GUI setup.

using JSON file
Use the JSON file – its way quicker!

Here we have used the JSON file to populate all the fields in the GUI install of VxRail. You only need to verify that everything is correct and provide the passwords.

New external MGMT VLAN option

There is a new option during the VxRail 4.7 version of the install that asks for a Management VLAN ID. The default is 0 to allow for Native VLAN to be used, or you can specify a different public management VLAN here. It should be different to the internal management VLAN used to separate the cluster build. The Internal Management VLAN was the -m option set in Step 1. This is very easy with SmartFabric now, as the VxRail Manager will make the necessary port configuration changes on the SFS enabled switches.

Now you can specify a external Management VLAN during GUI install rather than Native VLAN.

VxRail Manager automates the Switch configuration

There is a new task at the end of the GUI install and just before validation. SmartFabric services will now configure all the required VLANS that were specified, including Management, vMotion, vSAN and VM traffic.

SmartFabric switch automation
SmartFabric is smart! See it does the Network Admin tasks now!
switch fully configured.
Switch fully configured.

Validation eliminates human error

Trust but verify. Even with the SmartFabric automation, VxRail Manager still performs the important task of validating the install. Validation must pass before the actual deployment begins. This will capture anything amiss such as missing DNS entries, IP address conflicts , missing NTP. Basically anything that could prevent the build from completing successfully.

Validation
Trust but Verify = Validate!

Once validation has passed there is an opportunity to download a copy of the JSON file (useful if Step-By-Step was selected).

validation passed
Validation successful.

It is now time to kick-off the build. This is a fully automated process. There is zero value in manually setting up VSAN. By automating the process Dell EMC can be certain that every customer install of VxRail clusters are fully aligned to best practice. No snowflakes!

fully automated vSAN deployment
Go get a coffee – VxRail Manager will take care of the rest!
deploy SmartFabric
Hooray! The VxRail vSAN cluster is complete. Time to setup the OMNI plugin for day 2 operations of the SmartFabric.

How to enable SmartFabric for VxRail Step 1

I decided to document the steps I used to enable SmartFabric Services on VxRail.  These are partly notes for myself and Customer Solution Centre engineers that will likely need to showcase this capability very soon.  The demand for this solution is very high and the customers I have met are impressed by what is now possible (wait until you see the roadmap!). 

Note: This is not a guide for end user customers because a lot of what I write about is handled thru our automated deployment appliance; VxRail. A note of thanks to Allan Scott from New York CSC that helped with the first SFS deployment and documentation.

Step 1: Enable SmartFabric Services on the ToR Switch

  • Cabling the ToR Switches
  • Installing/Upgrading OS10 on Dell EMC Switch
  • Enable the VxRail Personality on OS10
  • Ready for Part2 – Deploying VxRail with Smart Fabric Services

Next Blog: Step 2: Deploy VxRail Cluster incl. ToR with VxRail Manager

Step 3: Deploy the SmartFabric OMNI plugin in VMware vSphere

Step 4: Virtualization engineer controls Day 2 Ops for the Full Stack


Getting Started :


How to enable SmartFabric Services on the ToRs

SmartFabric is supported on the 4100 series from Dell EMC. Current models are 10G – S4112 F/T, S4128 F/T or S4148 F/T  (25G coming soon). Sales can order these switches to be delivered from factory with OS10 and licenses already applied.

If you need the latest version of OS10 – get it here: force10networks.com , request login thru support page and download 10.4.1.x. Put OS10 .bin file and licence .xml file in a USB drive – insert USB drive into switch.

Cabling the TORs

First cable up ports 29 and 30 – 100GB cables for ISL (VLT).

Next cable up ports 25 and 26 – 100GB cables for Uplink.

Plug laptop into port 1 on switch.

Connect new VxRail appliances in any other port starting at port 2.

Installing or Upgrading OS10 on switch:

This is an optional step. The switches can be ordered and configured in factory, and so should arrive ready to begin at Step 2.

Connect the laptop to the serial port on one of the switches and start putty. Putty settings are 115200, 8, stop, none, none. I used a USB serial port so my COM port was COM3.

Powerup the serial connected switch – and break into ONIE mode by hitting ESC during bootup.

Choose “onie-discovery-stop” from the menu.

At prompt type: fdisk -l

USB Thumbdrive should be /dev/sdb1

mkdir /mnt/usb

mount -t vfat /dev/sdb1 /mnt/usb

Install OS10:

cd /mnt/usb

onie-nos-install /mnt/usb/XXXXXXXXXX.bin

Check IOS10 Version & Install License:

show version

show license status (skip next step if already installed)

license install usb://xxxxxxxx-NOSEnterprise-License.xml

Configure mgmt interface if required:

conf

int mgmt 1/1/1

no ip address dhcp

ip address 10.204.86.250/24

no shut

exit

management route 10.204.86.0/24 managementethernet

exit

Repeat these steps for the second ToR switch.

Optional step. Configure 40GB uplinks:

My showcase lab is using 40GB uplinks rather than 100GB so I needed to change the profile of the uplinks before applying the VxRail SFS personality. You can skip this step if you are using 100GB links.

OS10(config)# switch-port-profile 1/1 profile-2

Warning: Switch port profile will be applied only after a save and reload. All management port configurations will be retained but all other configurations will be wiped out after the reload.

OS10(config)# exit

OS10# write memory

OS10# reload

Enable the VxRail personality:

The SFS personality script is included in OS10. Once applied to each ToR switch, the switches will reboot with SmartFabric Mode enabled and you are now ready to perform a VxRail deployment from the VxRail Manager.

system bash

sudo sfs_enable_vxrail_personality.py -d 20 -a-m 2002

‘-d 20’ is a unique Domain ID that you assign to each cluster

‘-m 2002’ is a non-routed vlan used to do the initial build, local to the ToR switches only (Internal management network)

‘-a’ indicates that the port-channel on the upstream switches is configured with LACP

VxRail personality profile script options :


 
Domain -d <id> Required numeric value unique to data center (1 to 254) applied to ToR switch configuration settings Default: 1
Uplink -u <port,port> Override default 100Gb uplink ports Default: ports 25& 26
ISL -I <port,port> Override default 100Gb ISL ports Default: ports 29 & 30
Uplink tagging -t Whether external management VLAN is tagged or untagged when passed through uplinks. Default: untagged
Uplink LACP -a Whether LACP is active on uplink port channel (dynamic) or not (static). Default: static
Uplink breakout -b <2X50GE, 4X25GE, 4X10GE> Breakout 100Gb uplinks. Used to support connectivity to upstream switches without 100Gb ports
Management VLAN -m <VLAN> VxRail Cluster Build Network VLAN.
Default: 1

Validate Personality:

system bash

sudo sfs_validate_vxrail_personality.py

SmartFabrics is Smart for VxRail HCI

My guide to enable SmartFabric on Dell EMC switches is here.

Catch out my interview with Barry Coombs from ComputerWorld UK on SmartFabric… does everyone hate their own voice or just me?

Is networking in HCI complex?

Back in October I asked the question, is HCI networking easy? I stand by my assertion that it is already pretty simple once you understand the converged design for HCI does not require separate physical fabrics. Once you setup your required VLANS and appropriate MTU and multicast for IPv6 you are 90% of the way done.  So if it’s so easy already, then why am I so excited about Smart Fabrics for VxRail appliances? Start up a conversation with Ned the network engineer about the automated deployment and simplified life-cycle management capabilities of SmartFabrics and you will get back a blank dull stare. “That’s just a python script” Ned the Network Admin will say, “Take your fancy sales patter down to the Virtualization guys, we don’t want your kind round here!”

Ned the NetAdmin says “You’ll never take my switches!”

It’s not easy to impress a NetAdmin

Ned has a point I suppose. The Network Admins job is to move packets reliably from one part of the network to the other, monitor the network for any problems, and to design and build future networks.  The last thing Ned needs is dealing with end users complaining about network problems caused by poorly designed applications (its never the networks fault!). This is actually the main selling point FOR the use of Smart Fabrics. Let me explain why.

Before you understand why SmartFabrics for VxRail, you have to first understand the reason for choosing VxRail appliances in the first place.  I have written a few Blogs on this already here and here . In short it’s an engineered solution for vSAN that comes from Dell EMC fully validated and tested and automatically deployed and updated throughout its life-cycle.

VxRail appliances don’t require a Storage expert or Server guru and it even saves the Virtualization admin from having to spend countless hours reading design and deploy documentation. After deployment is done, day 2 simplified operations begins. As a result maintenance and updates and upgrades are made easy through a single bundle file that covers the entire stack (not just the software on top of somebody else’ hypervisor – and includes the hardware too.

Can SmartFabrics simplify HCI?

The last part of the HCI architecture that needed simplification was the network, so Dell EMC has had its sites on Ned’s cubicle for a while now. If we are going to provide a fully automated deployment experience for our customers, it only makes sense to include the Top of Rack switches that are being used by VxRail appliances.  After all why would the network admin want to be responsible for those HCI host ports anyways? If something goes wrong in the vSAN stack, Ned doesn’t want to be dragged in to a War Room to defend last weekend’s network changes. Ned knows the changes the network team made at the weekend were to the core only.

Now with Smart Fabrics for VxRail, Ned can still own the core, and leave the HCI network problems to the Virtualization team.  SmartFabric will fully configure a redundant TOR fabric for VxRail, and continue to maintain the network for the life-cycle of the HCI solution. When it’s time to patch the HCI network, SmartFabric will provide a bundle file, and perform a non-disruptive rolling upgrade to the network TORs leaving Ned free to watch old episodes of Futurama. If the HCI team needs to expand their existing VxRail cluster by adding a new node, then Smart Fabric will fully automate the changes to the TOR switch, no need for Ned to ever get involved.

Is BYO Networking still an Option?

One of the advantages for VxRail customers has been the fact that it is BYON (Bring Your Own Networking). This means that Dell EMC does not force you to take a switch from their portfolio into your datacenter. For some customers, this would be non-negotiable.  They may have standardized on a specific brand and prefer to stay that way, no matter what they run at the Storage or Virtualization layer.  VxRail networking is compatible with any modern low latent switch and the introduction of VxRail SmartFabrics does NOT mean that the BYON option is no longer a choice. Hopefully the automation that comes with SmartFabric for VxRail will entice some customers to converge the entire HCI stack and give Ned some peace of mind.

Here is a great Blog on vSAN and Network Switch choices from @LostSignal on this Blog: https://blogs.vmware.com/virtualblocks/2019/03/21/designing-vsan-networks-2019-update/

Update! This week I will be meeting Hasan Mansur at the Limerick Customer Solution Center who writes a great Dell EMC networking blog at https://hasanmansur.com/ . Hasan has written two great articles there about SmartFabric Services. Please check it out Part 1 here and Part 2 here.

Is advice from an expired VCP like drinking dodgy milk?

Update! VMware has removed the mandatory re-certification requirement from all current certifications! Read More about what this means here.

Expired VCP? Time to renew.

The concept of certification expiration is irksome to many in the IT industry. I remember when my MCSE timed out way back in the day. When I did the project management PMP certification I was very disheartened it expired in 2 years. I could no longer put it down on my CV any more. To keep current I had to log 40 hours of volunteering or attend various lectures on Project Management.

Have you an expired VCP? Keeping up with certifications in the technology world can be a daunting task. Even with the best of intentions to stay up to date, the day job can get in the way. If your role changes, sometimes so does your focus on keeping up with your training.  The next thing you know you are officially expired! Does this mean your past knowledge vanishes as well?

Can I just resit the new Exam?

VMware certification expired VCP
Certificate Expired!
VMware VCP

I suppose a more balanced view would be its always good to be continuously learning. Aren’t we all doing that though? Last week I signed up for the VMware vSphere: Install, Configure, Manage [V6.7] course through my employer. The is part of the Data Center Virtualization (DCV) track. There is only a current exam for certification for  VCP 6.5 as the 6.7 course is not yet ready.

You have to do a course now

The course I joined was delivered online with an Instructor (ILT) and the class had about a dozen students.  My old VCP certification was well expired at this stage! VCP 3 and VCP 4 seems so long ago now. I was a little daunted joining a course thinking I might be out of place.   The first day our instructor had everyone give a short intro. I was surprised to discover most people were in the same boat as me!

Shares, Reservations and Limits – Oh My!

Can I pass the VCP Exam without a course?

A few people had actually already passed the VCP 6.5 this year, but needed to attend the course in order to officially earn the VCP certification. It must be a challenge for any instructor, knowing that some students might lack the motivation to pay attention. I must say our instructor was excellent. If you ever get a chance to take a course led by Rita Thaker, do not hesitate! What I liked most was how she frequently used the whiteboard instead of the lecture slides. She has an excellent ability to explain a topic using a story with her pen and builds it up slowly over time.  Many students commented that they preferred her drawings and were busily taking screen grabs for later study.

You had to be there… Isolation or Partition What if Scenario.

Go on, the course is well worth it.

The course included two EBooks (Lecture and Lab manuals) delivered online through Evantage by Gilmore Global. You sign up for an account and can access the content on any device. The classes were hosted through the  Adobe Connect platform. This allows the instructor to control the learning environment completely. Participation was encouraged but controlled, the mics were muted unless a hand was raised, and normally the chat window was where we interacted.  This has a huge benefit in preventing the classroom Know-It-All or that one painful student that disrupts every lesson with an off-topic question/rant/story (there is ALWAYS one!).

My VCP was well and truly out of date so I needed to do a bit more to get back on track. I needed to attend the course and complete the course eval (to get course credit). Then I need to pass the vSphere 6.5 Foundations exam before I can finally try for the VMware Certified Professional 6.5 – Data Center Virtualization Exam (VCP 6.5 DCV ) .

I know a few people have expressed their annoyance with certification expiration and dismissed the trend as a money racket. To be fair the VMware training is really top notch. In my case I really did need to dust off the brain cells and get back into it.  Hopefully I will get a chance to take the exam in December (this year) and then I will hopefully do better at renewing within the 2 year time-frame, as you only need to pass the latest exam at that point.

Meet the Experts at VMworld Barcelona

This year I was fortunate to be given a ticket to VMworld in Barcelona as a partner attendee. Normally when I get to go to a company conference like DTW I have at least some booth duty – but this time I could concentrate on learning and networking. I had read all the guides to surviving VMworld, and digested all the advice and tips. I was careful to book sessions with presenters I wanted to meet before they filled up.  The app was an excellent resource and I used it to plan my days and stuck to the schedule I committed to.  I was very surprised to see many of the sessions only sparsely attended, especially when I knew the speakers were top class and the sessions had been booked out!

I was only given one small task for the event by the boss. The task was to evaluate the Meet The Experts area and Expert Bar and to find out as much as possible on how it worked for the event.  The reason for this is the plan is to run something very similar in Dell Technologies World in Vegas next spring.  Last year the Customer Solution Center had a section near the Hands on Labs area where customers could meet with Solution Architects 1on1 and discuss different products and solutions they were interested in.  The area was a success, we had many conversations and whiteboards were filled – but next year they wanted to see if we could improve the concept.

I must say I was well impressed with how the Meet The Experts and Experts Bar area were run in Barcelona. From what I have read about past VMworld’s the Expert Bar has moved from the VMware booth and now sits next to the Meet the Experts area which used to be called Expert Roundtables.  The location that was chosen was ideal in my opinion.  It was away from the Rock and Roll of the VM Village and Solutions Exchange, and placed outside of the Breakout Rooms.

At the end of any session, there is limited time to ask questions to the presenters so the Expert Bar gives anyone a chance to walk up and speak to someone while the question is fresh in their minds. The Expert Bar was a simple setup of one long table where engineers (not bartenders) served knowledge not alcohol. The table had room for 8 pairs of experts and a screen behind them displayed the details of their primary and secondary skill-sets. As customers fired questions across the bar, the experts could use the table-top as a whiteboard to explain concepts. The action was fast and furious and the Expert Bar was as busy as any in Las Ramblas.

The Meet the Expert sessions were all booked out weeks before the event, through the online scheduler just like any of the breakout sessions. You could search for a specific speaker, or a Topic and book them online.  This is exactly what I did, I booked 2 sessions with speakers that I wanted to meet. The session were at least 45 minutes each, with room for 10 attendees.  To me this is one of the highlights of the show, an opportunity to get into a small sessions with a well-known speaker and get a chance to have a discussion. I was amazed as I passed the area often to see empty seats. I spoke with the person at the desk checking badges of attendees and learned you could grab a no-show seat if they were full when you booked them.

I joined a session by Pete Koehler @vmpete with 6 customers. Pete and I knew each other virtually when Pete did a skype demo for me on new vROPS features after Dell World 2017. It was great to get to meet him in person and I was delighted when he recognized my badge when I sat down – we had a quick chat before he went into a discussion on vSAN availability scenarios.  The session was informal, mostly whiteboard, and the customers were able to ask questions. I was able to intro myself to the group and pitch Solution Centers story, as it turned out one customer asked to contact me after the event for a POC.

I had a second session with Myles Grey @mylesagrey about Kubernetes on vSAN, and I was the only one that turned up! For me this was excellent, because I had heard a lot about Myles and would much prefer to just have a chat while we waited for others to turn up.  Myles was an absolute gent and stayed for the full time-slot, he didn’t need to do that I would have understood if he headed off.  I had another Breakout session later he delivered on NSX that was also excellent.

When I got home from the event I gave a detailed report on the show and I am hoping that we are able to emulate a similar Expert Bar and Meet The Experts session schedule for Dell Technologies World in Las Vegas. If you have time in your conference schedule you would be well advised to include one of these sessions as part of your itinerary.
