London VMUG January 2017

Last week saw the first London VMware User Group of the year, another great meetup with many of the usual faces along with some new ones. This was another informative event at the TechUK site just off Fleet Street, and was again very community orientated. If you want to go and find out how people are using VMware products (and others in the surrounding ecosystem) then I’d thoroughly recommend these events- there’s just the right balance between real technical accounts direct from the coalface and marketing of new and interesting products Continue reading

London VMUG June 2016

VMUG LogoA rainy day in June saw me back in London for the latest VMware User Group event. For anyone who works with VMware products but has never been to a VMUG I cannot stress enough how great they are. VMUG is a community focussed and community run event filled with a bunch of really friendly, knowledgeable IT Professionals, and- thanks to vendor sponsorship- it’s free of charge so there’s little or no impact on your training/conference/personal budget or wallet.

Simplivity HCI for vSphere
This London event kicked off with a talk from one of the sponsors- Simplivity– discussing their Hyper-converged Infrastructure products for vSphere environments. This HCI solution is available as a turnkey appliance, or with third party hardware, such as Cisco or Lenovo.
The presentation and demo mentioned how crucial deduplication and compression are to this technology. Aside from saving physical disk space, there’s also the added benefits of backup and restore becoming faster and less costly from a network perspective.
For example when restoring a backup the software starts by sending the metadata- block hashes of the deduped backup. The target system can then determine which blocks it already has and which it doesn’t and only those new blocks need to be transmitted across the LAN/WAN to the system where the restore is happening. Additionally, these are the only blocks that need writing to disk so the amount of time spent on disk activity is also cut.

Server Hugger or “To the Cloud”
Following this we had a more light-hearted session. As it was the day of the Brexit vote, two teams of speakers attempted to persuade the attendees to be a Server-Hugger and vote to remain in the datacentre, or take the alternate path and vote to Leave for the Cloud. The general consensus was that Hybrid was probably the best option, but as that wasn’t offered it was down to the two choices and the Server-Huggers won the day.

VMware EUC Update
After a quick break the meeting split into two tracks. I opted for the VMware EUC update with Howard Bliss covering developments in WorkspaceONE, Horizon, and TrustPoint.
WorkspaceOne is a great idea- taking the EUC features of Airwatch, Identity Management, and Horizon and packaging them up in one platform. From the end-user point of view this looks slick, they download an app for their device from the regular appstore, sign in with their corporate email address, a profile is installed over the net and they are all set.
However I’m not sure it’s a fit for me from a Higher-Education IT point of view as the licensing is per-seat not based on concurrent users. Licensing this for tens of thousands of students a year could get expensive very quickly.
Horizon 7 went GA in March, and is “Hybrid-Cloud Ready”- offering the ability to manage cloud and on-prem VDI environments through a single pane of glass. Just-in-time Delivery means that 2000 desktops can be deployed in under 20 minutes, making the pre-loading of VMs for the start of a working day no longer necessary. This is helped along by February’s release of AppVolumes 3- apparently a preview of even better things to come later this year.
The Horizon Client has been improved, offering offloading of encoding from the CPU to an NVidia card and Blast extending to Linux to allow software encoding of Linux desktops. There’s also better integration with the OSX Keychain on the Mac client, and Aero window snapping, credential passthrough, and keyboard locale improvements in the Windows version.
The final piece of this EUC triumvirate is TrustPoint- The Image Service (Mirage) and the Security Platform (Tanium). The Image Service provides some useful abilities for those looking to do Win7 to Windows 10 migrations- including the ability to do an in-place upgrade from x86 to x64 platforms if you have any 32-bit installations that you want to lose. Amongst the benefits of the Security Platform is the ability to pick up and report on unmanaged endpoints appearing on the LAN within 15 seconds of them connecting.

SysTrack EUC Analytics
After lunch I chose the Lakeside Software session on using SysTrack in a Horizon Environment. In a bid to avoid PowerPoint poisoning they treated us to a short marketing video (see below) and then it was straight into a demo of the product in action.

I’ve used other tools in this space before, but it was interesting to see what SysTrack offers as an End-User analytics tool. There’s lots of information there and the ability to answer many questions- how many users are having a poor experience? (and is this number going down over time?) Are users in a particular department or location suffering? What resources do we need to migrate traditional desktops to VDI?
Data is collected by an agent that sits on the endpoint which works alongside browser plugins and VMware API calls for the monitoring of services hosted by vCenter. This agent data is pushed to a collector once a day to provide this trend analytics ability but there’s also realtime monitoring of the environment- spotting the apps causing a current peak in network traffic for example.

Boldly Going Where No DC has gone before
The formal part of my day concluded with a session titled “Extreme VMware Datacentres”, a chance for some of the more seasoned VMUG members to discuss their best war stories. We heard about some of the “awesome” places that VMware datacentres have ended up – in everywhere from dusty warehouses to nuclear submarines (you put a datacenter at each end so you can make end-to-end failover jokes!)or dark sites where nothing goes in or out, especially not a USB stick with an installation script on. Each location provides it’s own set of challenges, and requires the IT Pro to come up with new and unique solutions. This was thoroughly entertaining content from some community speakers.

Thanks!
No VMUG post would be complete without a personal thank you to the sponsors- Simplivity, Tintri and Lakeside Software. Further thanks to 10-Zig, PernixData, and Nutanix for sponsoring the after-event vBeers. Finally, thanks again to the London VMUG committee for organising a great event.

The UK national VMUG User Conference, held in Birmingham, is in November and I hope to make it. Maybe I’ll see you there?

London VMUG April 2016 (Part 2)

Last week was the second London VMware User Group of 2016– and I came away with so many notes I couldn’t justify just squeezing them all into one post. So, check out Part 1 here if you haven’t already and what to know what happened in the morning.

From the agenda I chose to start my afternoon with a look at VMware Virtual Volumes (VVOLs) and how they fit with the offerings from Nimble Storage. Nick Dyer ran through the company background and an overview of their products. One of these was InfoSight Predictive Analytics, this cloud based analytics solution collects data from across Nimble’s entire install base which not only allows them to use your own data to help spot problems and improve performance with your own infrastructure but also the other customers’.

On the VMware front he discussed how VVols abstracts away from the datastore model, allowing the storage vendor to present their capabilities directly up to the virtualisation level using VASA 2.0 technology. A VM is assigned a storage policy and therefore can be hosted on the most appropriate storage at a very granular level- this can affect not only the performance tier the data is placed on but also things like the volume encryption requirements.

Open Homelab Project

Coming Soon…..

After the afternoon break in the (Not Quite on the) Thames Suite we had a round(ish)table discussion about HomeLabs chaired by Alex Galbraith. I’ve mentioned in other posts that the London VMUG community set me on my HomeLab path, and this was a great chance to see what other people were doing and to exchange ideas. There’s a whole range of systems out there, from things like my small NUC-based deployment right through to people with racks of blades in their garden sheds. There are also those using or looking at hybrid or full cloud solutions to exchange that Capex for Opex, although if you turn that under-bed datacentre off you’ll need to heat your house more conventionally in winter . I thoroughly enjoyed this session and it already looks like it will lead to further community discussion and resources – keep your eyes peeled on #OpenHomeLab for more.

My last session of the day was with Neil Andrew from VMware who talked about vRealize Business. A mention of some of the features that morning had piqued my interest, and it’s was great to have this timely opportunity to delve deeper into the technology on offer.

vRealize Business can help answer those questions such as “How much is a VM costing me?” and “Is it cheaper to relocate this to a cloud provider?”. Although real Chargeback is potentially tricky to implement fully in many organisations, I could see how the idea of Showback is quite achievable and could not only help plan (re)deployments of existing services but also be a valuable tool in planning the budgets for new ones. The customer (internal or external) can be given a real cost of the infrastructure they are requesting, rather than a piecemeal hardware/ licenses/ manpower/ environment/ etc. cost usually calculated on a difficult to maintain spreadsheet.

After the closing statements, and the prize giveaways (including a rather awesome prize of an Anki Overdrive kit from PernixData) we adjourned to the 10-Zig sponsored vBeers where the technical discussions continued.

There’s another London VMUG in a couple of months, and dates for 2017 are already booked in. See you there?

London VMUG April 2016 (Part 1)

Thursday saw another trip to TechUK for the second London VMware Users Group of the year. It was, yet again, a very educational and entertaining community driven event with sessions covering a whole range of topics from enterprise scale implementations of hardware and software right down to the nitty-gritty of running your own HomeLab.

After the initial welcomes and introductions, the day kicked of with a session from Luca Dell’Oca of Veeam. Entitled “Veeam Backup and Replication: Worst Practices”, this was an often humorous look at what not to do when planning and implementing a backup regime. He covered many of the common mistakes when backing up a virtual environment, and although some parts were product specific (for example how the Veeam scheduler prior to v9 was not optimised for the hundreds of jobs a per-VM backup strategy would involve) there was a lot of generic advice. Highlights for me included

  • Remember that in-guest iSCSI connections will not be touched by VMware snapshots so don’t forget about them when backing up the VMs.
  • Use monitoring tools- in particular keep a close eye on storage space used by snapshots and performance. vCenter performance is critical and can often be a bottleneck.
  • When are other infrastructure tasks scheduled? Don’t run backups when your vCenter SQL maintenance plan is running for example.
  • Find the balance between one backup job per VM and one backup job for all VMs. Group VMs together based on backup policy.
  • Don’t be a cheapskate! Fast, Good, and Cheap is not possible.
  • It’s not necessary to fiddle with every advanced setting. Don’t change what you don’t understand!

Next on the agenda was the Plenary Keynote, where Simon Richardson of VMware went through the new developments in the Software Defined Datacentre portfolio. He pointed out that the only constant is change, and that means there’s always a lot to catch up on.

Simon discussed using the Hyperconverged SDDC as the best of both the traditional DC world and the Google/Facebook/Amazon “extreme” style of datacentre. Applying the analogy of a water company to IT he suggested we want to be in the position where we can turn on a tap and compute comes out.


There’s new features in the vRealize suite as well, vROps producing intelligent workload balancing and Log Insight for diving into the cause of a fault or performance issue.

vRealize Business was a new component for me (more on that later in the day) and I can definitely see the use of being able to show (or chargeback) the actual cost of a VM- taking into account all the factors- environment, hardware, software, support, manpower, and so on. Although there was little OpenStack adoption in the audience, Simon also touched on VIO- VMware Integrated OpenStack.

After a quick break in the Thames Suite (named in honour the breakroom in the previous London VMUG venue 🙂 ) I caught up with VSAN in more depth in a talk by Simon Todd (and earned some Cloud Credibility points along the way). VMware’s Virtual SAN is getting wider and wider adoption, even branching outside of the traditional Datacentre environment into Offshore Oil Rigs and even Submarines. This is more than just Business critical this really is Mission critical. The ability to deploy (and scale) large arrays quickly is a key selling point, multipetabyte arrays spun up in a matter of minutes and customers who had cut both costs and deployment times.

@MrVirtualSAN at @LonVMUG

What was my vmdk on VSAN up to at 4am last night? A user complained their service was slow.

Moving a bit more into the technical detail- Simon explained how VSAN is an object store with each VMDK, each file, becoming an object. This allows for per-object policy, so performance, IOPS limits, and resilience can be set, and then monitored, at the VMDK level. When pushing for that ultimate performance, this granularity could be of great benefit.

That brought us to the halfway point in the day’s proceedings, where there was lunch an and opportunity to catch up with the events sponsors- PernixData, Veeam, and Nimble Storage.
