I was quoting the random write IOPS number at 4kB. The theoretical sequential write bandwidth is fine, but I don't think that 15 IOPS can be considered respectable.
This is where ZFS could be a good thing. ZFS doesn't generally do small, random writes. If we get 15 random write iops at 128kBytes, then it is more reasonable. -- richard
They also list the number at 512kB, and it is still only 16 IOPS. This is probably an artifact of striping across a large number of flash chips, each of which has a large page size. It is unknown how large a transfer is required to actually reach that respectable sequential write performance, though it probably won't happen often, if at all.
They should send me one so that I can experiment :-) -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
