[storage-discuss] COMSTAR SRP Target: ARC case draft, Mailing list, Sources

[Peter Cudhea]

There has been progress recently on getting the COMSTAR port provider for the SCSI RDMA Protocol (SRP) ready to experiment with.   SRP accelerates the SCSI protocol by mapping the data transfer phases to RDMA operations. As a result an SRP initiator should be able to read and write data from a COMSTAR SRP target at high data rates with relatively low CPU utilization, using Infiniband RDMA for data transport. This letter is to bring you up to date on what has been happening and to point you to a few resources. The project page is up and running at OpenSolaris.org:  http://www.opensolaris.org/os/project/srp/ .  In particular, note the following recent additions: We have recently posted the source tarball for the files necessary to build the SRP target.   The code is licensed under the CDDL. There is a Draft ARC case.   This case will be submitted as a Fast Track within the next few days, so comments would be very welcome. There is a public mailing list (srp-dev) that we plan to use for ongoing technical discussions.   In particular, now that the sources are public we plan to do our code reviews through this alias.   Please join this list if you wish to follow our discussions. And of course, you can download the current binaries for the SRP target, to do your own experiments.  For now, we ask that if you want to experiment you add yourself to the srp-dev mailing list and introduce yourself. That's it for now.  Come on over and introduce yourself and let us know how you are using SRP. Peter Cudhea SRP implementation team
