Ok, so I have 2 Dell R710, twin 6 core Xeon w/HT, 16GB RAM, FC HBA acting as fileservers running Server 2008 R2
I have just purchased a Dell FC SAN made up of:
MD3600f
MD1200
24 x 600GB 15k SAS drives
The MD3600f connects into my SAN switch, along with the 2 file servers. The MD1200 connects via dual 6Gbps SAS into the MD3600f.
The File servers hold network homes for around 2000 users (mainly macintosh, so quite a read intensive workflow). We have about 1200 devices.
FS1 = ~1000 students roughly 2TB
FS2 = ~1000 students roughly 2TB
How should I configure my storage to suit this environment. It needs to be fast - we were using a sata based system before, but it couldn't deliver the IOPS we required, hence the new SAN.
Now the questions:
Should I have one raid 10 array per server, or one large raid 10 array split into luns per server?
Should I separate homes and profiles onto different luns, or physical disks - we do have some windows users too.
I only initially require about 4TB (after RAID and formatting) but this will grow as i move other users over.
Any thoughts / suggestions welcome.
Thanks.
