Wow that's odd, how large are your clusters?

We were hitting ours with 2 Intel clusters (1,000+ cores each) and 4
racks of BlueGene/Q (65,5535 cores, 4096 nodes).

However, we do have our GPFS metadata on an SSD array connected to 2
dedicated NSD servers (active/active) and our SFA10K's are frontended by
4 NSD servers each (again active/active pairs to give redundancy).
