Beware, I've just been burned by the Promise ATA/133 RAID controller...it will only rebuild the array if you give a new drive of identical geometry....unlike SCSI based raid which only need a similar or larger sized drive.
I'm exploring 3ware's offerings and am enthusiastic about their SATA based RAID controllers...should give similar performance to 1gb/sec Fiber Channel but for a heck of a lot less money. Once I get one running, I'll report back to the list....oh yeah, 2gb Fiber channel is truly wonderful stuff under redhat....I used Qlogic HBA's and they scream.... /brian chee University of Hawaii ICS Dept Advanced Network Computing Lab 1680 East West Road, POST rm 311 Honolulu, HI 96822 808-956-5797 voice, 877-284-1934 fax ----- Original Message ----- From: "Thomas Ryan Gordon Sr" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, December 04, 2003 10:32 AM Subject: Re: [luau] videl.ics.hawaii.edu disk failure - Your Help Needed > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > R.Scott Belford wrote: > > | I am saddened > > Don't be sad, I was just learning that the RAID is in-fact > software-based and all 160 gigs will be usable.
