We're currently using 7.02 and I'm going to be moving it from the existing 2003 32bit server to a different 2008 64bit server. The newer server has dual quad core E5420's, 12g, and all 15K SAS drives. I'm looking for input on the hardware raid configuration based on experience and design of the Kerio Connect database structure. My options are:

1. Raid-1 for OS with Raid-1 for Database
2. Raid-1 for OS with Raid-10 for Database
3. Single Raid-10 volume for OS and Database

Typically we use option #2 when using SQL for the DB. We have about 100 users with about 25 using KOC, 15 using Webmail on shared workstations and the rest using Outlook with POP/SMTP. I plan on eventually moving all Outlook users to KOC ( Although I keep hoping for Kerio to change to PST for the DB). Have 12 users syncing Windows mobile devices and a couple of Ipads. Considering switching about 75 phone users to Blackberry platform and installing BES. I try to get three years out of a server but don't want to over design it if the software won't use it.

Thanks,

Mike

How many users? That server sounds like major overkill on the CPU and ram.

I figured as much on the processors and memory but I picked up some year old Poweredge 2900's with that configuration for $1700ea. I listed the users in the original post. I'm mainly looking for input on the raid and whether Kerio runs more efficient if the DB is on a seperate array. Some software seems to like being on the same array as the OS.

Go for RAID1+0 for store and 2 disks in RAID1 for OS. You didn't mention how big is your store, for comparison I have 153 users, 700GB store (over 4 milions files!). I recently moved from XSan on Promise (RAID5 of 1TB SATA 7200rpm disks) via FC to SAS expansion chassis loaded with 600GB, 15k rpm SAS disks, connected to an ESX host and presented as RDM to an ubuntu (4G, 2cores) VM. The difference in speed is simply jaw-dropping!
