I have seen different implementations of read caching in arrays and even inside hosts, just to be able to cope with boot storms of VDI workloads. When using linked clones caching really helps; all the VDIs being booted perform massive reads from a very small portion of the infrastructure: the replica(s). VMware came up with a nice software solution to this: Why not sacrifice some memory inside the vSphere nodes to accommodate read caching there? This is what CBRC (vSphere 5) or Host Caching (View 5.1) is all about. And… It really works!

What happens during a boot storm

First of all, we need to figure out what happens during a boot storm. Even wondered just how much data Read the rest of this entry »

EMC and VMware have published a joined Reference Architecture where an EMC VNX5300 using a minimum configuration of disks squeezes out the required IOPS for a thousand VDI users. That is awesome stuff, but how to go about using and remodeling this RA for your own needs? In this blog post I’ll try to put some numbers to it, both validating and enabling you to resize for your needs.

A very cool use case: VMware View and 1000 vDesktops running off an EMC VNX5300

This is a very VERY cool one. You can find the Reference Architecture Read the rest of this entry »
