#LonVMUG 15th May – another great VMUG!

Posted by Sam McGeown

VMware User GroupYesterday saw another fantastic London VMUG with lots of quality sessions and opportunities to network with peers and friends. The committee seem to do a fantastic job every time and this one was no exception, so thanks to Alaric Davies, Jane Rimmer, Stuart Thompson and Simon Gallagher!

One of the best things for me about the VMUG is the chance to chat with some of the smartest and most influential people in the VMware world – a trip to the coffee table provided a great opportunity to “chew the vfat” with two of the VMUG's biggest characters, Mike Laverick and Ricky El-Qasem – all before any sessions had started.

The first session of the day, after the obligatory coffee and biscuits, was presented by Itzik Reich of EMC’s ExtremIO talking about the all-flash offering. For a non-native English speaker I was thoroughly impressed with how he engaged with the audience and spoke. My main take-away was that you can’t treat flash in the same way as magnetic disk – it’s not just a faster version of the traditional spinning platter but requires a whole new approach as to how it’s used and managed. That may sound obvious but I think a lot of solutions treat flash as such, imposing magnetic disk concepts like RAID which don’t make the best use. Flash != magnetic disk, don’t treat it the same!

Online VMware Forum – my thoughts

Posted by Simon Eady

VMware Online ForumThis was the second online event I have attended in the last few months, the first being the VMUG Virtual event back in January. One of the aspects I enjoyed the most about that event was being able to chat  to many well known and familiar faces from the wider community.

In this recent event there was a lot of focus on the various offerings from VMware  with a good deal of focus on VSAN, NSX, Horizon and vCHS but certainly not neglecting their other offerings.

The live video streams were great and even offered audio translations as they took place.

I really did like the way the website is laid out to give it that intended virtual conference feel.

Infinio accelerator – quick review

Posted by Simon Eady

INFINIO LOGOI recently came across Infinio and after reading about the unique way it tackled the problem of increasing I/O and reducing latency I was curious to see how it would perform in my lab.

A few things I would like to point out. First of all Infinio works only with NFS storage, secondly it does not require flash storage as it utilizes the host RAM instead however it provides only read acceleration.

I chose to setup 1 NFS store per array (RAID1 & RAID0) to see if there were any discernible differences. I had several existing lab VMs (DC and other general VMs) but for additional I/O load I added 3 I/O intensive VMs for each NFS volume.

RAID1

You can see distinct increases to I/O when switched on

Book review: Networking for VMware Administrators

Posted by Sam McGeown

NetworkingForVMwareAdministratorsI recently got my hands on a copy* of Chris Wahl and Steve Pantol’s Networking for VMware Administrators and was very keen to read it – especially given the reputation of the authors. I came to the book as someone who is at CCNA level (although now expired) and someone who regularly designs complex VMware networks using standard and distributed switches. I would class myself as having a fairly decent understanding of networking, though not a networking specialist.

The book starts out at from a really basic level explaining OSI, what a protocol is etc. and builds on the foundation set out as it progresses. Part I of the book gives are really good explanation of not only the basics of networking, but a lot of the “why” as well. If you’ve done CCNA level networking exams then you will know most of this stuff – but it’s always good to refresh, and maybe cover any gaps.

Part II of the book translates the foundations set out in Part I into the virtual world and takes you through the similarities and differences with between virtual and physical. It gives a good overview of the vSphere Standard Switch (VSS) and vSphere Distributed Switch (vDS) and even has a chapter on the Cisco 1000v. One of the really useful parts of the book are the lab examples and designs, which takes you though the design process and considerations to get to the solution.
