We are a small non-profit running Server 2008 R2 & Exchange 2010 at our main office using vSphere. We may have to open a satellite office across town, so I'm wondering what kind of server I should get. There would be 15-20 users at the satellite. Would something like this suffice?

PowerEdge T310 PowerEdge T310 Chassis with upto 4 Cabled Hard Drives and Quad Pack LED Diagnostics edit

Processor Intel® Xeon® X3430, 2.4 GHz, 8M Cache, Turbo edit

Memory 8GB Memory (4x2GB), 1333MHz Single Ranked UDIMM edit

Operating System No Operating System edit

Internal Controller PERC S300 3Gb/s SAS/SATA Internal Software RAID adaptor edit

Hard Drive Configuration Add-in PERC S300 (SAS/SATA Controller) supporting 3-4 Hard Drives – RAID 5 edit

Hard Drives (Multi-Select) 500GB 7.2K RPM SATA 3.5in Cabled Hard Drive edit

External Controller None edit

Power Supply Power Supply, Non-Redundant, 375W edit

OS Partitions None

and another Cisco ASA 5505 security appliance & a 48 port switch. Am I forgetting anything?

OS licensing is not an issue as we get charity prices for MS software-$8 for Win 7, about $150 for Server 2008 R2 for example.

Any input is greatly appreciated!

Depends on what they will be doing on the server. Other things to consider:

1. Backup power.

2. Backup data.

3. Bandwidth requirements.
