Cinder

Support LIO as an iSCSI backend

Registered by Eric Harney

Currently Cinder most often uses tgtd to create iSCSI targets for volumes. This blueprint aims to enable use of LIO, a more modern alternative, by interfacing with python-rtslib. A new iSCSI TargetAdmin class will be created for this.

LIO: http://www.linux-iscsi.org/

This came out of the mailing list discussion about the lio-support-via-targetd blueprint, as it is a more straightforward method to support LIO before implementing a targetd driver.
