vSAN Lite

During the London VMUG last week I had the fortune to speak to Paudie ORiordan (@oriorp) and this was an excellent opportunity to express some views of storage with VMware

We started talking about the roadmap of vSAN and also its adoption. I explained that I have had thought of using the product for a few deployments but there tends to still be a view of keeping storage and processing separate regardless of SDDC or hyper converged solutions being out there. I still think this is a general fear within most IT guys but best kept for a separate post.

I explained that in the past I had used PernixData due to the ease of integration with any type of back end storage and configuring some simple VMs and SSDs with the hosts. This is at the point where we discussed it would be a great opportunity for VMware. We exchanged the thoughts of the fact some end users still find it hard to comprehend the whole converged set up or even move away from traditional storage. Sometime this being down to a recent major investment in traditional storage.

This is where the idea of ‘vSAN lite’ came to fruition, the concept of being able to trial the benefits of vSAN by adding some SSDs to your hosts but still leverage your back end storage. I thought this was something they could work on due to the ROFC being depreciated from the VMware VSphere product line. Oddly enough I had used this a few times in the past.

I know VMware would find this quite hard to position and they would be worried that the adoption of the vSAN product may decrease but maybe if it was offered as a trial only with no extensions this would provide the best of both world. The end user to not only reap the benefits and also be able to capture the required statistics to sell it back to their steering committee or board but also see the real world experience.  Maybe during the trials there could be an agreement where all statistics could be sent to VMware for analysis and also for publications on real world IO savings and IOPS charts. What would also make this sing is the use case for each deployment such as VDI, Processing or standard infrastructure.

I do also wonder though if it may be easier for VMWare to acquire PernixData and then embed this into their road map.

10Zig and DataCenter Gaming

Want a way to bust those January blues? Want to game from your DC? Well if you have spare server kicking around or at least one you don’t mind shutting down and it has VT-D extensions enabled I would have a chat with 10Zig and grab a VMware Horizon demo. Why…. Well here is why

You of course will also need a compatible GPU but I found that a Quadro K2000 I had access to did more than an ample job to prove this in concept.

I ran this very brief POC on a HP DL380 G7, VMware 5.5 and a small iSCSI RAID 5 LUN and got these results. I would be amazed to know what I could have got with more tuning and an SSD or two. As you can see it got around 120FPS at points so pretty good going.

I am going to do a full post on the 10Zig clients as well as they put simply they rock and I would like to test them further. I would love to do a true show down of RDP, PCoIP and also Citrix. From this it would be good to see how Citrix XenDesktop compare against VMware Horizon in a head to head app demo.

I did try a few other older games but I had issue getting them going but either way it’s an interesting notion that you can get full 3D graphics from your data canter. Maybe this is also a good way at last to get some of your Adobe fans (Also Mac users) within VDI as you can at last really provide them a true GPU and support. It also can hopefully satisfy your DR plans as who has a Mac spare or a high end graphics machine for when disaster happens!
