UK VMUG Event Review

Yesterday I had the pleasure of attending the fourth UK-VMUG annual conference at the National Motorcycle Museum in Solihull. For those that didn’t make it, I’ve put together an event review for your viewing pleasure. Apologies for the crapness of the pictures, taken with my phone unfortunately!

 

Joe Baguley Keynote

IMG_20141118_091319

After a brief introduction from VMUG leader Alaric Davies, the day started with the now usual keynote from Joe Baguley, CTO for EMEA. This year the keynote was entitled “Rant as a Service” and after setting the scene for around 30 minutes, the key message is still around software defined enterprise. It was my interpretation that there was a small pop at a hyper converged company whose name may or may not contain nuts on the basis that EVO:Rail and EVO:Rack can give you the same level of support and performance without having to buy into a single vendor. I’ve been feeling for a while that there isn’t a lot of love lost between the two parties, and I don’t know if that’s true, but I don’t find it particularly helpful when constant implied barbs are being traded. Just my opinion!

The point of EVO:Rail is to have the infrastructure up and running within 15 minutes. The value here is that you can go to 8 partners and pick which stack and value add you want. It’s not a single vendor lock in as such, as most customers already have an existing relationship with the likes of Dell, etc. EVO:Rail is 2U in size and has four blades installed. Not dissimilar to Nutanix and UCS in that respect, though of course the UCS chassis has a larger form factor. For larger installations or special use cases such as VDI with NVIDIA graphics, the bigger EVO:Rack will be required.

One interesting line was the ongoing idea now that abstraction and obfuscation takes place in as much as key components such as disks and raid controllers are being replaced by software and public and hybrid cloud solutions. This of course is becoming transparent to the “end user” as we move towards a hybrid cloud type of world. If a disk controller fails, it’s OK, software can take care of that. Lose a data centre? That’s OK too, we’ll just move to another one in the background. I’m not sure we’re totally there with that one yet, but it’s an interesting concept none the less.

Then we had the discussion about what is “Enterprise Scale” these days? As consumer electronics demands increase exponentially (photo uploads, data requirements, data production, etc) then most things these days really are “Enterprise” grade as they have millions of people using them daily, not just the tens, hundreds or even thousands in an “enterprise” environment.

White boxes are also now are taking the place of large monolithic proprietary solutions. EVO:Rail again was mentioned as an example of this, where you get a pre-built, predictable and validated vSphere environment from whichever hardware vendor you prefer. The irony that you’re still locked into VMware technologies was missed at this point, but I think I see where the point is here.

VMworld Update – Julian Wood

I then went to the VMworld Update session with Julian Wood. One thing I’d have to say is that there was too much to fit in for 40 minutes. That’s not Julian’s fault – as he noted, once you look into it, there are so many product releases, updates and acquisitions to keep track of that you could spend all day talking about it! There was some discussion around the vRealise suite (I’m not spelling it with a “z”!),  what that means and how there is on and off premises solutions for that now. vRealise is essentially the management and automation tools bundled into a suite, so products such as vCloud Automation Center, Log Insight, vCenter Operations Manager etc.

CloudVolumes was also discussed, where applications are installed to a VMDK and then this VMDK is connected and presented to desktops in a fraction of the time it takes to do ThinApp etc. As I was listening to this, I started to think “what are the storage requirements though?  Read intensive, or are blocks cached.  How does this work?”. “Do we require any back end infrastructure such as MS-SQL etc.?”

On the EUC side, big strides continue to be made and VMware are really competing with Citrix in the application presentation stakes, as well as adding further improvements to the core View product, including Cloud Pods (or Linked Mode for View, as I like to call it!), where you can break the current scalability limits but also provide an additional site failover for virtual desktops if required, plugging one gap in the previous product set.

vSphere Futures – Duncan Epping

The next session was with Duncan Epping. His sessions are always well attended as he’s usually on the bleeding edge of what the company is doing internally, plus I’ve found him to be pretty honest in his responses to some issues that have cropped up, especially around Virtual SAN. I made quite a few notes around what was discussed, and it’s probably easier to break them down into bullet points:-

  • All flash Virtual SAN coming, to increase the configuration options for two slot blades, where currently you need flash for cache and spinning disk for content
  • Virtual volumes (VVols) policies coming that will based per VM
  • This functionality will be based on an array that supports virtual volumes
  • IO filters directly in the hypervisor for those arrays not VVol aware
  • Storage DRS VM IOPS reservations, so we can migrate workloads to other storage if reservations are not met
  • Storage DRS has better awareness of thin provisioning, dedupe and replication
  • Resource and Availability Service is a new web based tool that uses exported DRS settings to simulate failure of resources and ensure design is correct, validating such things as Admission Control settings
  • FT support for up to 4 vCPU
  • No more vLockstep or shared VMDK for Fault Tolerance,  10Gbps networking will be required
  • The ability to vMotion “anywhere”, requirement is that both vCenters must be in same SSO domain
  • vMotion has a 10ms latency tolerance now, working on 100ms tolerance for long distances
  • The vCenter Appliance will scale as well as Windows version now, and will be the future of vCenter releases
  • SQL server supported externally for the vCenter Appliance
  • Task pane will be coming into bottom of Web Client
  • Less nested right click options to make the Web Client interface cleaner
  • Task  concurrency, performance  charts and other features will be introduced into the Web Client
  • Linked Mode will be available for the vCenter Appliance
  • Content library for ISOs etc, replicated across sites. Also includes templates, OVFs etc. Same as Hyper-V Libraries, by the sounds of it

One very interesting thread was around Project Fargo. This in essence is a “re-imagining” of the snapshot process and will allow for the creation of Windows virtual machines in around 2 seconds. In the lab, Linux VMs were spun up in less than that, the overhead on the Windows side was mainly down to customisation and joining AD etc. Another way of thinking about it is “Linked Clones on steroids” in the sense that you have a parent virtual machine and lots of child virtual machines. Duncan’s blog entry as linked above goes into some good detail on what you can expect from this initiative.

Horizon View Architecture and Design – Barry Coombs & Peter Von Oven

I then went to the session by Barry Coombs and Peter Von Oven about Horizon View Design and Architecture. This session wasn’t really a “death by PowerPoint” session, but more a key points and brief discussion at a high level as to what you should be looking for in a good Horizon View design. There are always little nuggets or anecdotes that can be useful that maybe you haven’t come across before that only really come out of experience. One good point from this session was that you should never let the IT team speak on behalf of the end users, so in other words, don’t assume IT know necessarily what the user experience is like, because they can’t know every individual use case.

The key point of performing a desktop assessment phase and also a proof of concept was also re-iterated, and I can’t agree with this enough. To chat to IT and some end users is not enough. It’s useful as part of the whole engagement, but you also need key performance metrics and also a proof of concept to see what works and what doesn’t work. Think of a PoC as the first draft of a document that requires lots of iterations to get it “just right”. To perform a desktop assessment and some stakeholder interviews and then think you can roll an effective VDI environment first time out of the gate is total fantasy.

Any VDI deployment (whether it’s View or AN Other solution) should be an improvement on the current “physical” end user experience. Again this is a given. If you’re spending time and money replacing a solution people are familiar with and comfortable with, it needs to be visually an improvement on what they already have, or the solution will simply acquire a “bad name”. One interesting idea was the notion of having a “Departmental Champion” – an end user who wants to positively influence the outcome of the project. They can interface with other users and help cascade information and feedback backwards and forwards. This can give you a view inside the PoC that you would not normally have.

Some other brief points included not forgetting to factor in VM and graphics overhead when right sizing a solution, these are commonly forgotten about (guilty!) and user concurrency should be measured in advance. Generally I use the rule of thumb of 80% concurrency, but in an organisation that has shift patterns, this may not be appropriate. Make sure the solution scale!

EUC Update – Peter Von Oven

My next session was another EUC session, this time with Peter Von Oven from VMware. Again, a lot of key messages came out pretty thick and fast, so a bullet point summary is included below:-

  • VMware’s strategy is still the three pillar strategy of SDDC,  EUC and Hybrid Cloud
  • AppVolumes (formerly known as CloudVolumes) will be available in December
  • Horizon Workspace can disable icons based on physical location. It’s context aware in that sense. So for example, R&D portal is not accessible from Starbucks, but is from a corporate LAN
  • Horizon Workspace provides a central point of management
  • AppVolumes will be in the Enterprise Edition of Horizon View
  • View 6 makes it possible to co-exist and transition from XenApp environments
  • Windows 2008 or 2012 server required for RDSH Application Publishing, and can mix and match if required
  • Easier than upgrade to XenApp 7.5 in the sense that a new infrastructure does not need to be stood up
  • Seamless application remoting,  even on Mac
  • Use vCOps for View and do a 60 day assessment of your environment – though I’m not sure you get the same level of information as you do with say Stratusphere FIT
  • Use thin clients not zero for unified communications in VDI
  • Fully supported by Microsoft for Lync over PCoIP
  • Webcam and mic done using USB redirection
  • Use case for Thinapp is portability and isolation, AppVolumes for performance
  • Application catalogue allows user self service of applications, can remove after 30 days etc
  • Workspace Suite is Horizon + AirWatch, includes Horizon Advanced for Workspace
  • vGPU like Citrix,  coming Q1 next year – vGPU is covered here and is essentially dedicated hardware VGA acceleration but with the consolidation ratio of sVGA. Still uses NVIDIA driver for application validation and support
  • Horizon Flex out in December, delivers containerised desktops in much the same way as the old VMware ACE product
  • No dependency for Horizon Flex on Mirage at the back end
  • Requires Flex policy management server and provides time limits, grace period, remote lock and wipe, USB lock down, etc

Cisco and VMware – Chris Bashforth

For my final breakout of the day, I went to the Cisco partner presentation on UCS and VMware View. I have to say I didn’t find this session all that useful. I don’t know if it was due to the graveyard slot at the end of a long day or if it was just the general dryness of the topic, but I never really felt like the audience engaged with the speaker and the atmosphere fell a little flat. We were given a brief overview of UCS for those who have never seen it before and then a quick run through of the blade and chassis models available and which are recommended for VDI deployments.

I’m still quite new to UCS having been a HP guy all of my career, so there were some interesting items in there but I didn’t feel I got a lot out of this session and left a little disappointed. For those folks wanting to use NVIDIA GRID cards in their UCS deployments, you will need to use C class rackmount servers for this purpose, with two slots available per server for this purpose. B class blades are densely packed and simply do not have the space to accommodate this card.

One thing to correct is the speaker’s comment that NVIDIA vDGA will support 8 users per server – this isn’t true. Direct passthrough means that you connect the physical VGA card to the virtual desktop on a 1:1 basis. I can only assume he got mixed up with the upcoming vGPU which will be a similar passthrough arrangement, but with the ability to get a higher consolidation ratio of up to 8. If I misinterpreted these comments, please feel free to let me know.

Closing Keynote – Chris Wahl

The closing keynote was from Chris Wahl, industry legend and double VCDX. The force is strong with this one! The session was entitled “Don’t Be a Minesweeper”. I went into the session wondering what the correlation was between stealing bits of beer from tables (my definition of a Minesweeper) and the IT industry, but it turns out he was referring to the cheesy clicky clicky game of previous Windows’ vintages. The general gist was that automation is the way forward, we’re seeing that now, and it pays dividends to be ahead of the curve by learning some scripting now. Whether that be PowerShell, PowerCLI, Python or anything else.

I did particularly enjoy Chris’s attempt at using British slang. Top marks to him for differentiating between bollocks (bad) and dog’s bollocks (very good). It’s not always easy for an American to grasp such as concept depending on whether or not said objects are canine connected, but I think he did pretty well!

Summary

Overall it was a very good day and a hearty well done to the VMUG committee who put it all together. This was my third VMUG-UK and each time it just keeps getting bigger. I don’t know how many showed yesterday, but I heard on the Twittervine that nearly 600 had pre-registered, which is absolutely fantastic. I did wonder if the event is now starting to outgrow the venue – the solutions hall was packed and difficult to navigate and lunch and brew breaks got quite cramped for space, but that’s a relatively minor thing.

I didn’t get much chance to look at the booths in the solutions hall, but it’s difficult when you’re a partner with long standing relationships with vendors to have something new to talk about sometimes. I did however get to see some old ex-colleagues as well as chatting to some folks I hadn’t seen in years, which was great.
