Announcing new open source iSER (iSCSI/RDMA) target

We are releasing code to add support for iSCSI Extensions for RDMA (iSER) to the existing STGT user space SCSI target. It uses OpenFabrics libraries and kernel drivers to act as a SCSI target over RDMA-capable devices. The code has been tested against the existing Linux iSER initiator over InfiniBand cards, but should be specification compliant and work generally.

A bit of documentation is included, and a short technical report is available at http://www.osc.edu/~pw/papers/iser-techreport.pdf . For performance, a single SCSI client using iSCSI over gigabit ethernet does 100 MB/s. iSCSI over IPoIB gets 200 MB/s, and iSER over native IB sees 500 MB/s.

More information on STGT is available at http://stgt.berlios.de .

The seven iSER patches can be downloaded from:

	git://git.osc.edu/tgt

or browsed at:

New and modified files are distributed under a GPLv2 license. I'll submit individual patches to stgt-devel for review and eventual inclusion in STGT.
