Good article… data rates are impressive…

The only filesystem? Not for a while now. Okay, NFS over RDMA is a Good Thing(TM). But what about:

o NFS v4.1, aka pvfs2?
o SRP, which allows block storage over IB, which leads to GFS and OCFS (also CXFS and QFS) over IB?
o Lustre, which is now OSS?

I’ve implemented 1500-node clusters with NFS, and it’s always a good starting point. NFS over RDMA will provide additional options, particularly as an inexpensive upgrade path from NAS heads to Linux-based storage servers for existing clusters. But NFS has plenty of limitations (always has), and it’s important to investigate the (suprisingly mature) alternatives that are available.
