" You surprise me. I have eight disks RAIDed with Solstice Disksuite (or
" whatever Sun's currently calling it) on a single-250MHz U30 running
" Solaris 9, and it can easily saturate a 100Mbit connection.
" That is, to be fair, just a stripe, not RAID5.
apples and oranges. striping - especially across controllers - is a
great way to improve disk i/o. raid5 requires the metadriver to
calculate/analyze ecc sums on the fly every time there's an i/o.
that's the penalty you pay for the ability to pull one of your raid5
disks out without crashing your system.
