Sorry forgot to change the subject line: Understood.
How about virtualbox? The deployment guide has guidelines for storage on using virtualbox as desktop provider. However it does not mentioned anything about number of spindles. The capacity can be calculated fairly easy but number of spindles will affect the performance. Is there a guideline or formula to calculate that? For the same size of capacity - say around 1TB, I'd rather use 11x146GB raid 5 than 3x500GB raid 5. But it's hard to decide when number of trays and cost are involved.

A single pair of disks mirrored should be adequate. As far as sizing of the disks that hold the actual VMDK files, that depends. Their sizing has nothing to do with the client software that you are running. Whether it's a Sun Ray or a repurposed PC, the backed storage to the VM disk files will be the same. If you have individual OS instances and each is unique, then you will have to multiply the size of your Virtual HD by the number of VM's. If you are using the premium version of View which has the Linked Clone technology, then your disk usage will be smaller. Linked Clones allow you to only write the changes or differences between VM's to disk instead of the entire OS. Sun also has this capability in it's VDI software using Sun virtualization back end. These savings are only realized if your 100 users are using the same master image as a baseline. VMWare has plenty of documentation and sizing guidelines for this.
