We have 8-core Xeon X5460 servers and we've never had an issue with any one of them with 40+ users running Java programs (Computer Science students) and Firefox. The systems have 24 GB RAM and I have to agree that RAM is more of a concern than CPU. However, since Solaris is a multiuser OS especially when used with Sun Ray, I would strongly suggest more vCPUs, minimum 2, recommended at least 4. However, my experiences have been purely bare metal so I don't know how these metrics should be adjusted when using ESX. I would be interested to hear about anyone that has experience with that as we are considering virtualizing our Sun Ray servers in the future (although probably not with ESX).

If they're just going to be browsing the web, you'll be able to add more users than if the users were running NetBeans and compiling programs.

I have a customer with a deployment of a couple dual-socket Xeon servers to host 100 DTU's and they're looking to grow this environment to support an additional 350. Instead of deploying more physical servers they'd like to deploy SRSS on Solaris VM's (VMware ESX) and add these to the FOG. My questions are: 1) The customer, based on VMware's best practice guide, likes to deploy only 1 vCPU and only add as necessary - this is because they're primarily a Windows shop and for single threaded apps 1 vCPU works better than 2 vCPU. I would argue that Solaris and SRSS are very threaded with each kiosk session spawning new processes - this VM would benefit from *more* vCPU's. Thoughts?? 2) The customer uses Xeon 5400-series CPU's - what practical numbers are people using (or have achieved) for the number of concurrent SRSS user per core? Thanks, Jason
