I guess this is really my question. Budget is less than $50k per site and they need around 20TB storage. Two nodes with MD3 or something may work. But could it work (and be successful) with just servers and internal drives? Should I do FPO for non hadoop like workloads? I didn’t think I could get native raid except in the ESS (GSS no longer exists if I remember correctly). Do I just make replicas and call it good?

We are now at GPFS 4.2 with support for 3 way replication and FPO. Also we have Raid controllers, IB, and "Native Raid" and ESS, GSS solutions and more. So more choices, more options, making finding an "optimal" solution more difficult. To begin with, as with any provisioning problem, one should try to state: requirements, goals, budgets, constraints, failure/tolerance models/assumptions, expected workloads, desired performance, etc, etc. This message (including any attachments) is intended only for the use of the individual or entity to which it is addressed and may contain information that is non-public, proprietary, privileged, confidential, and exempt from disclosure under applicable law.
