We've been looking and apparently the RocketRAID 1640 is a 4 channel serial ATA that supports RAID 5... of course we're going to keep searching... We haven't identified a dollar minimum.... we just want to remain concious of the cost. We are a small shop and only support 20 - 30 email users, but would like to build to be able to support up to 50.... -----Original Message----- From: Jeffrey Robillard [mailto:jrobill@xxxxxxxxxxxxx] Sent: Tue 7/15/2003 10:22 AM To: [ExchangeList] Cc: Subject: [exchangelist] Re: Disk partition for Ex2k with Disaster recovery.... http://www.MSExchange.org/ I dont think there are any serial ata raid 5-10 controllers out yet are there. adaptec has one coming out soon, but its not out yet. all they have is raid 0 and 1. how low are you trying to keep costs? $3000, $5000, $8000 -----Original Message----- From: David Liles [mailto:dave@xxxxxxxxxxxxxxxxxxx] Sent: Tuesday, July 15, 2003 11:16 AM To: [ExchangeList] Subject: RE: [exchangelist] Re: Disk partition for Ex2k with Disaster recovery.... I am in the process of identifying requirements for a new Exchange 2000 box and would like some clarification.... In an effort to keep costs manageable we were considering serial ATA drives in some sort of RAID configuration. If we have a separate drive for the OS should it also be a serial ATA drive or can it be a standard IDE drive on one of the motherboard controllers? If not recommended, I guess it should also be a serial ATA drive on its own controller? We were thinking of a RAID 5 configuration for the storing of the Exchange database and logs. This would be a separate serial ATA controller.... Not being a hardware techie... I'm not sure if I'm on the right path regarding the hardware configuration.... Any advice from those who are?

Partition 1 Partition 2 Partition 3 Boot and OS (Mirrored) Page File (One on each drive) Exchange Tran log (Mirrored) 2 SCSI One partition. Mirrored. Exchange DB. The reason for have 2 page files, each on a separate partition on separate drives, is it is not recommended to mirror the page file, and having 2 will keep you from having a blue screen in the event of a drive failure.
