Hello all... been reading forever and am posting the first time...
We will have 6 of the 36gb 15k RPM drives setup on a 2757 controller. I'm trying to decide what would be the 'best' way to configure them in terms of parity sets. Can anyone help me with the decision? I'm picturing either 6 drives in a single parity set, or 2 parity sets of 3 drives each. I'm interested in getting some thoughts on which setup makes more sense in terms of protection and performance. I know that by setting them up as 2 parity sets of 3 drives we will lose more capacity, but I want to get some feeling for how much additional performance or protection that setup might offer compared to the 6 drives in one set. Can anyone offer any further advice?
The system is a 950cpw Model 800 that runs a single Domino workload (200 users max) and a Websphere workload.
Thanks for the help...
