Hi,

What is the hardware requirements for VMware 5.5 VDI per user.  Currently we have 6 VMware host servers and the CPU utilization peak at 100% on all of them.  Our current hardware contains:

CPU 12
Memory 147446
Storage: SAN 4TB

I think you are going to need more hardware. VDI is very datastore intensive, and memory for clients.

This is the specification of our VDI Machines for our users.

We started off, with 1 vCPU and 4GB, and in our performance tests, with our office application load, users reports, after a year of testing, this was the sweet spot for us.

Windows 7 - 2vCPU, 6GB RAM.

Windows 8 - 2vCPU, 8GB RAM.

We've had many issues in this area with VDI deployments, when using conventional storage, either local SAS or SAN based storage. For our VDI deployments we now use Fusion-IO products (SSD) based, to save on electricity, air conditioning, the expensive of SAN deployment, and help us with "VDI storms". e.g. big slowdowns that can occur when a lot of users log into the system at the same time.

Once users boot up, log in and load applications, the storage I/O typically settles down to a minimal level. The IOPS difference between a desktop VM that is booting and after it has booted is extreme, which can make architecting storage for VDI environments a challenge. A typical desktop VM running Windows 7 will generate from 50-100 IOPS while is it booting; once it is running normal workloads, the average IOPS drops to about 5-10. Therefore, to successfully meet the I/O demands caused by boot storms, your storage needs to be designed to handle the worst-case scenario.

We've been using and deploying/implenting Fusion-IO products since 2008/2009, Fusion-IO have come along way, and now their products are OEM and rebranded by HP and Dell. Fusion-IO have now been purchased by SanDisk (yes the USB flash drive and SSD maker!)

We have been using the IO-DriveDuo 640GB, sized accordingly for the number of VDI desktops required.
