2000 Seat VDI Deployment Benchmark (By Dell & Microsoft)

A new Blog post on MSDN by the Microsoft RDV team how they recently partnered with Dell to build a 2000-seat VDI deployment (all pooled virtual desktops) at their Enterprise Engineering Center (EEC) in Redmond.

“…The key idea of this architecture is that VDI compute and storage are per host; think of these as VDI pods, and you can just add more pods to host more users. The key advantage of such a design is that we only need high availability (HA) type storage for user docs and settings, and typically such an infrastructure already exists in an enterprise. If not, it can be built mostly independent of the VDI. And just to complete the picture, some shared storage might be required depending on your preference for HA configuration of back-end services such as SQL, although the VDI-specific services have application-level HA and can work either way.

Following is a high level overview of our deployment.


In the preceding diagram, please note that the capacity of this deployment is primarily a function of the number of VDI hosts; one could easily add more hosts to grow capacity without upgrading the management infrastructure, but bear in mind that you may need to increase storage for user docs and settings (this analogy holds for traditional desktops with roaming or redirected folders too). That said, another benefit of this architecture is that the design of storage for user docs and settings is decoupled from the VDI design, which makes it especially ideal for pooled virtual desktops.
