I'm not sure tat this level of analysis has been done. I think tt
would be pretty easy to place a #/spindles vs cost/user graph to see
the sweet spot. It might be stepped in such a way to call out where
you should buy with your pricing.

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. Thank you very much.

The Sun Ray Server component will use very little in terms of Disk. 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.

This is great info. How about storage? How many users can you put
on
say 14 drives? (with CSM tray in mind). Thank you so much.

Three cores would be a nice starting point. That's 33 concurrent
sessions each. If your concurrency is less than 100%, then you can
get
by with less.
Some customers scale much higher than this (50/core) and some less
(25/
core). It completely depends on the screen updates the users are
driving with applications and window management.
As far as memory goes, a very safe bet is 100MB/user. This would
allow
for very large screens for each user and some headroom. For typical
1280x1024 screens, 75mb is more of what is seen.

Team,
I'm looking for practical numbers to use for sizing SRSS to host 100
concurrent users connect to VMWare View using the Sun Ray Connector
for VMware View Manager.
- How many Xeon 5540 (@2.53 GHz) cores would I need?
- How much memory per user should I plan?
BTW, the Xeon 5500-series "Nahalem" CPU's @ 2.5 GHz, which offer
significant performance compared to previous generations.
Thanks,
Jason
