Yes, that's right. > Has Windows Server 2008 been tested to work with AoE storage using the > R11 protocol version? As far as I know, no Windows driver has yet taken advantage of this new mechanism. The current SR firmware supports it, though, according to the changelog on the SR Support Page. http://support.coraid.com/support/sr/ (More below.) > At my shop we unfortunately do a fair bit of > iSCSI work and none of the FOSS iSCSI targets seem to implement > reserve/release.

I thought that the protocol document did a pretty good job of succinctly but clearly explaining how reserve/release works in AoE. If you haven't already read the new section, please check it out. If you have, though, it would be interesting to know what remains unclear, although we might be getting esoteric enough to take the discussion off list. ;) > > Coraid remains committed to simplicity.
