Musings of a Random Dude
Monday August 25, 2008 Just recently, the Updated NFS/RDMA integrated into Nevada. The history of NFS/RDMA goes back years in Solaris, when Sun originally put in a pre-standard version into Solaris. More recently, work in the IETF sought to standardize how NFS over RDMA would work (the drafts are now moving towards RFC status). The integration now gives Nevada an implementation that corresponds with the new IETF version (replacing the old pre-standard version).
In practical terms, saying over RDMA is a code for InfiniBand and the slowly emerging iWARP. So what the integration into Nevada means is Solaris will now have the updated IETF NFS/RDMA version for InfiniBand with the door open for iWARP when that comes along. And of course, Nevada is the codeword for propagating into the OpenSolaris releases.
Just to recap where we are on InfiniBand ULPs, Solaris now has implementations of IPonIB, SDP, RDS, NFS, SRP, uDAPL (used for MPI). The HCA story is here and here. And more is coming, including a port of the Open Fabrics Userland Verbs, iSER and certification on various SPARC platforms. So stay tuned for exciting days ahead...
