I assume you mean two 4 core processors. We run the blade configuration below. BL460c's G1, G5 and G6's with 32gb ram. If you have the opportunity you should look at Intel's Nehalem core processors. They rock for virtualization. We run 4 vm's per host on the G1's and G5's. 2 vCPU's and 4096 GB ram on XenServer 5.5 and Provisioning Server 5.1 sp2 We see some spikes during login. Server handles workloads once all users are logged in fine.

I was led to believe from our vendor that these boxes should run a couple of XenApp servers and have plenty of juice to run file and print and maybe an application server. What I am finding on the XenApp servers that the process monitor counters spike in the red every time someone logs on. Is this normal or does these counter need to be tuned for there environment? thanks Ronnie Visit our website : www.ltai.ie __________________________________________ Lufthansa Technik Airmotive Ireland Limited.
