Since my last set of testing, I ended up installing NexentaStor on the same hardware, disabled the ZIL, and did some other tweaks, and am seeing performance on par or *exceeding* my much more expensive purpose-built Equallogic array. Even with disabling the ZIL with OpenSolaris, I still had far less performance than I'm seeing here. I have yet to use the COMSTAR iSCSI version in NexentaStor as it's not working in 1.1.5 (supposed to be fixed next week in 1.1.6) but that's supposed to be even faster. Considering trying NexentaCore to see if the same performance can be had there as well. _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
