RAID in FreeBSD

[Robert Covell]

I have a 7506-4LP running Raid 1 on a 4.8 box and it had been working like a
charm.  It is not low profile, but don't know why it would matter.

Sincerely,

If you don't get SATA or SATA2 the card looks expensive, but I have only
been shopping for a card for a few days so I can't give great advise on
brands.  I would suggest storagereview.com for that.

Have you tried emailing msmith at FreeBSD.org?

Also FreeBSD can do raid5 with vinum, or gvinum now.  It uses the cpu
and works with whatever controller but will be slower from what I have
heard.
