Also, you may want to scan through the archives, as questions like this have been asked and answered before. www.dejanews.com is your friend and Oracle! We have a mail server that supports few hundred domains supporting few >thousand pop accounts. What kind of RAID configuration suits a fairly >busy mail server ? For speed, reliability and cost, have a look at the 4port 3ware card (www.3ware.com) in RAID 10 config. Two RAID0 sets mirrored together. Get yourself some inexpensive drawers ( eg http://www.startech.com/ststore/ItemDetail.cfm?Product_ID=IDE66BASIC) and you have a fairly fast, reliable and cost effective setup. Hot swapable SCSI RAID is also nice, something like the AMIMegaRAID, or the supported Adapec will do as well. Decide what fits your budget. The final price does not necessarily linearly scale with the protection/benefits level for your situation. Also, lots of RAM so that mailboxes can be cached as they are being read helps a lot. With the price of RAM these days, 512MB will make any server happy. ---Mike -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Network Administration, mike@sentex.net Sentex Communications www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
