Ok, so Im purchasing a two node win 2k3 cluster that will run SQL 2000 in an active/passive failover HA config.
I want to have an external SCSI storage array and have sourced the IBM EXP400 that will support 14 drives.
As I understand it - a single SCSI adapter can have 14 drives connected to it.
So in my external storage - one of the disks will be a quorum disk leaving me with 13 active drives for data.
What i want to know is whether i can have two SCSI adapters in each of my servers, and connect the two node cluster to two external SCSI storage enclosures. That way I'd have 13 active drives in the first array and 14 active drives in the second array. Is there any restriction on doing this? Can I have two SCSI adapters running in my servers? Would there be any restrictions on this imposed by Win 2k3 or SQL Server 2000 (i.e. will they only recognize a limited total number of SCSI disks?)
Basically - I don't want to be limited by the 2TB of storage I can get out of one external storage array. I want to get about 4 TB but i don't to jump up to SAN. I also want to stick with the major hardware vendors - as a very high level of SLA is required - if there's hardware failure I want the part replaced by the vendor within 10 hours or so. Thats why I'm looking at IBM, Dell, HP.
