Quick question, we've gotten the green light to upgrade out Exchange 2003 environment.<br />
<br />
Current setup includes 2 x Exchange 2003 servers, one local one in a remote office.<br />
<br />
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.<br />
<br />
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..<br />
<br />
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? &nbsp;Could I actually step down to &nbsp;[gasp] 7200rpms or should I stick with the standard 10k?<br />

New Exchange 2010 hardware specs

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
