We've been using RAID5 on 3Ware 7506-4LP, 9500S, and 9550SX controllers from 3Ware without any issues. When a drive dies, we use the web GUI to remove the drive from the array, replace the drive with a new one, mark the new one as a hot-spare, and then watch as the controller rebuilds the array with the new drive. On the 7506 we have to power down the servers, but our big multi-TB systems have nice SATA hot-swap backplanes. Haven't had any issues running FreeBSD 5.x (twe), 6.x (twa), or Debian Linux 4.x (3w-9xxx) on these cards. Our largest array is currently 4 TB usable space (2x 2TB arrays combined via LVM). Most of our systems are < 1TB. -- Freddie Cash, LPIC-2 CCNT CCLP Network Support Technician School District 73 (250) 377-HELP [377-4357] fjwcash+freebsd@gmail.com
