Picture this: Your single (let's say IDE) pagefile drive fails, so your system crashes. You run down to your store or computer shop to buy a new drive (system still down) You install the disk in another machine (since Exchange might not start up without page drive) (system still down) You partition/format the drive (system still down) You install the new IDE disk in your exchange server (system still down) You start up Exchange.
If you can afford all that downtime, go ahead and use a single drive. But now let's look at RAID1 swap: One of your swap disks fail.. Raid1 is broken so machine keeps running on one disk You take the bad disk Offline and pull it out You stroll and whistle your way down to your store or computer shop to get a new disk, maybe even have a couple of doughnuts on the way... You insert the new disk in your exchange server. run the RAID tools, rebuild the RAID. Pat yourself on the back for 0% downtime. -----Original Message----- From: Andrey Fyodorov [mailto:[EMAIL PROTECTED]] Sent: 03 October 2002 4:23 PM To: Exchange Discussions Subject: RE: New Exchange Server If it happened once it will probably happen again. I see no big benefit of putting page file on RAID. If I had a limited number of drive bays, I would rather have a separate RAID1 for transaction logs and a separate RAID5 for informations store database files; and if no more drive array bays are available for the page file volume - I would stick an IDE or SCSI drive in the CD-ROM bay or some other available space and connect it to the onboard controller and achieve better performance instead of perceived reliability. -----Original Message----- From: Robert Moir [mailto:[EMAIL PROTECTED]] Sent: Thursday, October 03, 2002 9:38 AM To: Exchange Discussions Subject: RE: New Exchange Server So because you once had a problem with RAID that caused it to stop working must mean that it's always unreliable for everyone else every time?
