Hello, we are debating on migrating our current KMS to a new server, with a different Raid architecture and we want to hear feedback on other users migration experiences.

Current setup:
KMS 6.3.1 140 users, 100 active on a daily basis
mailstore size approx 80GB
user mailstores range from 2GB - 800MB
single processor 2.66Ghz, win 2K3 Web edition, 2GB RAM, Raid 5, 4 disk 146GB SAS 15K drives.

Moving to:
Win2K3 Standard R2, 4GB Ram, 2 dual core procs 2.33GHz, 2 Disk 146 GB Raid 1 15K SAS Drives


Can anybody offer experience with a similar situation. We do not have a way to test this...

Thanks,
Chris

Actually I mis typed, it should have been moving to: (2 Quad-core procs) not dual core

Save some money and don't bother with the second proc. Instead, buy as many drives as you can and put them in a RAID 10 array. With the number of users you have, 4 disks would be my absolute minimum (I have half the users you do and I have 6 15k drives). Also, make sure your RAID controller has R/W cache with as much cache as you can get.

Thank you for your reply, the second server is actually already in the rack, it's a spare server we just had that seems to be a little beefier.

If the raid configuration is most important, including disk and disk speed, maybe it would be in my best interest to completely rebuild the server it is currently on, putting windows 2K3 standard, doubling the RAM, and making the RAID Raid 10...considering they are already 15K SAS...??
