I've located the CCM server 6.1 hardware support matrix sheet on cisco.com, but it's not very detailed about what the servers are.
I was looking to get an HP DL320 G5 with the Xeon dualcore 3050, however, that particular server setup doesn't support redundant power supplies. The next step up server that does, doesn't come with the 3050. So, I'm looking at getting a DL 320 G5 with the Xeon 3210 Quad-Core, however, I can't find if HP supports this.. anyone know if there's a support matrix on their site that shows the details of each support machine?
(I found a detailed one for Unity)
