Recommendations for hardware RAID? no 3ware please !
Hi, We have ~15 FreeBSD servers using different hardware. Most of the servers we have are using recent IDE 3ware controllers (eg 7450) in a RAID 5 configuration. I've always found these more trouble than they're worth. Sometimes the wrong drive degrades and so when I replace the drive and try and rebuild the array it repeatedly fails. I need to take the whole machine offline and spend a long time sector-scanning each drive (using powermax - they're Maxtor drives) and generally discover there is a hardware fault with one of the other drives.. If the drive with the actual error cannot be repaired using a sector level tool, it's then impossible to rebuild the array because the errors on the non-degraded drive keep causing the rebuild to fail so I have to rebuild the whole machine on a new array. Anyway - I like the IBM X series and we have had good experience with IBM's support... Unfortunately FreeBSD doesn't seem to fully support the Adaptec hostRAID technology yet - It will recognise the array in FreeBSD version 6 but if you pull a drive out the whole thing dies (it is dangerous to half-support a RAID controller like this). Can anyone recommend a vendor (Dell, HP etc) that will make my life easier? (no reboots, good management tools and monitoring) - I'm a bit over putting machines together myself to save a few dollars. Thanks, Adrian. ___ freebsd-hardware@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to [EMAIL PROTECTED]

We run a FreeBSD 6 IMAP server on an DL360G4p and we're very happy with it. FreeBSD is installed on the two internal, hot swap SCSI disk using the built in SCSI raid and there's an MSA 1000 external box with 7 SCSI disks for mail storage. We had a disk failure in the DL360G4p about a month after delivery. The red light when on and we got some logging. We removed the failed drive, plugged in the new drive and the array came online soon after. Painless. Guy -- Guy DawsonI.T.
