Unfortunately I don't know how much of the spec is available publicly :( With that said there are two parts of VVols support: - out-of-band management API; probably would be a userspace daemon - additional SCSI stuff - mostly use of heirarchical LUN addressing, and orders of magnitude more LUNs. Needs kernel support to handle the new addressing (not too big a deal) and probably architectural changes to scale to many more LUNs. - R. -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
