Quick question, we've gotten the green light to upgrade out Exchange 2003 environment.
Current setup includes 2 x Exchange 2003 servers, one local one in a remote office.
Collectively we have ~400 mailboxes between the two and for ease of management (and purchasing) I'm looking at replacing both with the exact same hardware.
So I know that 2010 relies more heavily on RAM than drive speed, so I'm looking at an HP DL385 G6, 2xOpteron 4-way 2.4ghz, 16gb ram, 2x146gb OS array, 4x300gb data array all SAS drives..
Compared to our DL380 G2 with quad P3 xeons this should be a major step up. But what concerns me in the hdd speed.. I've been told disk speed isnt as important but how unimportant is it? Could I actually step down to [gasp] 7200rpms or should I stick with the standard 10k?
