Yes. Really the only other option we have (and not a bad one) is getting a v7000 Unified in there (if we can get the price down far enough). That’s not a bad option since all they really want is SMB shares in the remote. I just keep thinking a set of servers would do the trick and be cheaper.

It just alters the disks below the GPFS filesystem layer and looks like a normal GPFS system (mostly). I do think there were some restrictions on non-FPO nodes mounting FPO filesystems via multi-cluster.. not sure if those are still there.. any input on that from IBM? If small enough data, and with 3-way replication, it might just be wise to do internal storage and 3x rep. A 36TB 2U server is ~$10K (just common throwing out numbers), 3 of those per site would fit in your budget. Again.. depending on your requirements, stability balance between 'science experiment' vs production, GPFS knowledge level, etc etc... This is actually an interesting and somewhat missing space for small enterprises. If you just want 10-20TB active-active online everywhere, say, for VMware, or NFS, or something else, there arent all that many good solutions today that scale down far enough and are a decent price. It's easy with many many PB, but small.. idk. I think the above sounds good as anything without going SAN-crazy.

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.
