iSCSI support for Compute/Nova
Nova currently supports persistent volumes using ATA-over-Ethernet (AoE). This is to discuss adding iSCSI support as an alternative.
Goals
Support high-end storage arrays
Support OpenSolaris / Nexenta (?)
Support Linux iSCSI target so that developers can get up and running quickly
Progress
Work is progressing in a launchpad / bazaar branch:
https://code.launchpad.net/~justin-fathomdb/nova/iscsi-volumes
Currently the Linux iSCSI initiator & target are supported, and it works (though is not heavily tested)
Questions
Is the Linux iSCSI target stable (enough)? Is there a different target we should be supporting?
Has anyone looked at Sheepdog in detail? ( http://www.osrg.net/sheepdog/ )
Also Check into IET ISCSI-target (http://iscsitarget.sourceforge.net/) We use this heavily is production.
What are the requirements around LUNs / targets? Right now, each volume is exported as a target with a single LUN? Is this workable?
Which high-end storage targets should we support? Can we get EMC/NetApp/whoever to give us a loaner?
What extra functionality can they offer us that we can expose? Snapshots? Different storage classes? IOPS guarantees/throttling?
