Ok...got a break from the 25xx release... Trying to catch up so...sorry for the late response...
The 6120 firmware does not support the Cache Sync command at all... You could try using a smaller blocksize setting on the array to attempt to reduce the number of read/modify/writes that you will incur... It also can be important to understand how zfs attempts to make aligned transactions as well....since a single 128k write that starts on the beginning of a RAID stripe is guaranteed to do a full-stripe write v/s 2 read/modify/write stripes.... I have considered making an unsupported firmware that turns it into a caching JBOD...I just have not had any "infinite spare time".... -Joel This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
