Hi DJM, I've only ever seen one Sun Ray deployment so don't take my opinion as gospel, but my first reaction was your hardware is going to be underpowered. We run 80 Sun Rays on 3 x quad core 3GHz blades, 40% of which are Windows TS connections, the rest are CentOS 5 Gnome. While there's significant room to expand I would estimate our environment would be capped not far past 200 Sun Rays in peak hour using the same servers. Even now we have to do a little desktop maintenance like killing off the occasional Opera / Firefox process going crazy. How many concurrent desktops do other people get out of their hardware?
I'm also interested in why you're considering VMWare? What bonuses does VDI grant you, does it allow you to fit more desktops compared to running native Linux sessions?

Hi all, a customer of mine (a local college here in Switzerland) want to replace their 700+ existing PC's with 1200 Sun Ray DTU's. Wow. So I am slightly over my head here and I had hoped someone with more experience could help me with a few architectural suggestions? The customer is very much "pro x86" and fiercly "pro Linux" and "pro VMware ESX". So my initial thought was to go for e.g. 2 x Sun Fire X4600M2 (for redundancy and e.g. VMotion), and in each of these servers: ... 8 x Quad-Core CPU's, 256 GB RAM, 292 GB total disk space per server My thoughts why I thought this was a good configuration: - works with VMware Infrastructure - with VMware we could implement VDI - with VMware they could create, clone, copy & move virtual machines as they wish - this is a college, so in a worst case all 1200 DTU's might be used at the same time, so the hardware must be able to take the workload - with e.g. two virtual SRSS instances I could share the workload between the two X4600M2's, e.g. create a fail-over group etc. Latest news is they want Sun Secure Global Desktop too .... So with above configuration I think the hardware could handle it? Any suggestions? What configuration would you suggest to handle 1200 DTU's at the same time (worst case)? Or is the above configuration total overkill? I'd be happy for your suggestions ... Regards + Thanks in advance, DJM.
