Server S[ecifications

[heprox]

My company is about to finally migrate to a Cisco based VOIP solution. Our Cisco partner informed us that they can provide the Cisco servers or that we can use our own. We are primarily an IBM/3Com shop, so we are replacing some of our switched for Catalyst PoE switched, but I want to use IBM x345/346 servers for Call Manager and Unity. What would everyone recommend the specs for these servers to be. I was thinking something like:

Dual P4 3.2 Ghz
2Gb DDR/DDR2 (x346) RAM
U3 SCSI 15K RPM (RAID 10) (use 4 x 73 Gb)

Is CCM RAM intensive? Disk intensive? Should we partition a particular way, or does the CCM install do it for us? What about the Unity server specs? Finally, Since we are moving over to Catalyst switches, should we place the Cisco system on its own subnet, or maybe just its own VLAN in order to restrict LAN traffic? We regularly use 3Com VLAN's to restrict traffic (by port) to production servers is this OK with CCM and Unity?

You should definatley move all traffic onto a "voice" VLAN.

On cisco's website it will give you the exact model number of the server that it supports. Be sure to get the exact model specified or you will have problems when building the server. The CCM install will install the OS etc etc
