Hi All,

I'm needing to plan for a database cluster.

I need two different arrays.

The cluster will be 2 Microsoft SQL Server boxes in an Active/Passive sql cluster.

This requires a network based quorum disk that is shared between each server to hold session data, etc.

I need something fast, that has redundancy, and is reliable. The entire quorom disk doesn't need to be more than 20GB (maybe even as small as 1GB).

I was thinking about just getting two NAS boxes that can be directly connected to mirror each other, and using drives as small as 9GB in an array. like 5x9GB in a Raid 5 array.

Along with this, I also need a high speed NAS/Direct attach storage cluster that can hold up to 500GB. I've seen some Supermicro machines and dell machines that can hold up to 20 or so disks. So I was thinking of doing like 16x36GB in raid 5, with a few hot spares, using 15k drives. This storage device would need to connect to the servers via iSCSI.

Does anybody have any recommendations?

If you're set on 15,000 rpm SAS drives, then why not go with Fibre Channel over Ethernet ("FCoE")?

I'm not an expert on FC, however; I just do a lot of reading.


And, if you are space-constrained and you don't have lots of unused rack space,
the QuadraPack Q14 from Enhance Technology will enclose 4 x 2.5" SAS drives
in a single 5.25" drive bay, using their proprietary backplane & SAS cables:

Enhance Tech can also provide you with turnkey Network iSCSI RAID Storage:

... also with RAID 6 support:

Areca and a few others also support RAID 6 in hardware,
so that RAID level will provide you with extra security
not available from lower RAID levels.
