catching up: IB in Solaris 11 Express
By user12611518 on Mar 18, 2011
The "Nevada" development train produced various OpenSolaris releases which added various new IB features. Then, in last November Solaris 11 Express released, which in turn is leading to Solaris 11.
When you compare Solaris 10 to Solaris 11 Express, you will notice some new IB features. In storage, iSER (iSCSI Enhanced for RDMA) and the SRP (SCSI RDMA Protocol) target are now available (these had released previously under OpenSolaris). Also RDS (Reliable Datagram Sockets) version 3 is now available to improve Oracle RAC support. SDP (Sockets Direct Protocol) got a make over to drastically improve performance. Further, the SDP interposition library (libsdp) is now available to provide transparent redirection from TCP to SDP when desired. IPoIB also got a new dladm administrative interface to realign it with the rest of networking.
Finally, Open Fabrics User Verbs (OFUV) was added in Solaris 11 Express. Many folks regard the OFED Linux distribution as the de facto standard for InfiniBand. OFUV is a port of most of the userland libraries and commands of OFED. Now Linux folks can recompile their Linux InfiniBand apps on Solaris 11 Express and use many of the familiar InfiniBand administration commands that they are used to.
And of course, more is coming for Solaris 11.
As always, this blog should only be regarded as my personal opinion. If some official statement contradicts me, I am probably wrong.
