Running Postfix,Bind,Apache2,PHP,Postgresql,etc I'm running a Netfinity 5000 with IBM ServeRAID 3L adapter. I won't say it's good (it lacks any kind of online RAID management or monitoring from within FreeBSD AFAICT), but it works and is definitely 'entry level'. This machine works as a webmail/IMAP server for ~150 users, listserver hosting ~50 mailing lists and as incoming mail scanner/gateway (postfix+amavisd+spamassassin+clamav) for another mail server with ca 500 users. Getting it to work with FreeBSD 5.2.1 was a pain, but 5.3 seems to run good. Doesn't boot with ACPI enabled, though. As to other suggestions made in this thread, they don't seem to be relevant for Netfinity 5000 since I can't think of a way to use ATA drives in this machine. --- ...

Mirroring shouldn't use much CPU, for example, but parity might put a bit of a load on a hard-working system. That's a good question, though. Several cards are listed in the hardware compatibility notes, but they stop short of saying "this card is completely supported" or "stay away from this one". What cards have people had good luck with in practice? I've been using a Promise FastTrak S150 TX2/plus for close to a couple of years now. It supports two parallel and two serial ATA drives. I bought it to support my parallel ATA drives and then I thought I'd migrate to SATA, but I haven't done so yet. I've got two parallel drives in a RAID1 (mirrored) array. This configuration is discouraged by the manufacturer because the drives have to share a cable and failure on one drive will very likely lock up the system, but that's not really important to me. I'm more worried about hardware failure than uninterrupted uptime. I've been using this setup since FreeBSD version 5.2, and I'm currently running 5.4. The dmesg looks like: atapci0: port 0x9800-0x987f,0x9400-0x940f,0x9000-0x903f mem 0xfb00-0xfb01,0xfb027000-0xfb027fff i q 22 at device 2.0 on pci2 atapci0: failed: rid 0x20 is memory, requested 4 That little failure at the end has always been there in one form or another. It doesn't seem to hinder operation as far as I can tell though. I've only had to use the built-in maintenance utilities once to fix something, and that was after a really bad kernel upgrading accident. It worked fine. Overall I'm happy with this card. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Re: Hardware RAID Cards..
Just be careful on what card you choose. Aside from simply making sure there are drivers for it, you also have to check on the little things. Like, oh, being able to non-destructively grow the size of the RAID5 array. I bought a Promise SX6000. I have 3 200GB drives that will be in RAID5. If I wish to add a 4th, it can't add it to the array. I have to destory the array and start over. Like I said, the little things. :\ Also, remember that growfs is your friend.
