In theory, a hardware RAID should give you better CPU utilization. After all, a seperate processor (or DSP, etc.) would be doing all of the work that your main CPU is currently doing. Furthermore, your CPU would be able to forget about all of the extra abstractions of Vinum, such as plexes, subdisks, and so on - the RAID could look like one single harddrive. In reality, I don't think that the RAID controllers would protect the CPU from nearly so much work, and I'm almost positive that your CPU will be orders of magnitude faster than the processor on the controllers. -- Kirk Strauser The Strauser Group - http://www.strausergroup.com/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
