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
