I've been running 5.2.1-R on an isolated data backup server with 3ware ATA 8 channel RAID with 250GB maxtor drives. It does daily backups of multiple servers. You can monitor array status using 3amd daemon. So far uptime is almost a year. It does nothing but backups... I'm not sure how it would compare VS SCSI RAID under high IO. We only use SCSI RAID on our web servers which get pretty busy. I'm looking forward to using LSI RAID cards with 5.3 I'm using one with 4.x, it's been working fine for several months, now. Unfortunately, the monitoring suite is broken due to some bug and I wish someone would fix it. I emailed the author, but there was no response. I'm relying on SAF-TE enclosure to tell me if any of the drives are dead. Frankly, there isn't much choosing when it comes to SCSI RAID and FreeBSD as of late. It's either the adaptec, which has a share of it's problems, or LSI which works fine but lacks monitoring tools. -Simon On Tue, 11 Jan 2005 13:50:49 -0500 (EST), Gerald wrote: >I recently setup a SATA RAID1 box on a highpoint controller.
