Thanks for all of your information. I think we are going to build a new server the proper way and migrate everyone over. I don't think that our CIO would want to risk us doing a DR situation if we don't have to even if it involves more work. Reason being that we have been so busy that no one has ever let us come up with a strategy. This environment has been here for about a year and a half and still no time for us to complete one. That's a whole nother story.

You would need to crack open the box and disconnect the NETBAY3 from the current channel and connect it to the 2nd channel on the controller. This would break the established RAID. Then you would build the box from the ground up, starting with the IBM Raid CD so you can recreate your drives. If you do this I would recommend you do the OS/Log as a RAID1 (with 2 logical drives) and enroll the 3rd drive as a spare. Then do the 2nd as a RAID5. Think of it as a way to test your DR plans. The good news is if you do it this way and still don't get the performance you are looking for, when you add the EXP you will only have to tell exchange to move your log files to the new drives. -----Original Message----- From: Gonzalez, Alex [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 18, 2002 3:41 PM To: Exchange Discussions Subject: RE: Hard Drive Utilization We have Netbay3. Am I going to have to rebuild the box to do all this? -----Original Message----- From: Waters, Jeff [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 18, 2002 3:29 PM To: Exchange Discussions Subject: RE: Hard Drive Utilization Do you have the Netfinity NETBAY3 so that you can use up to 6 drives? If you don't, and you aren't using something like the EXP300 external bay then you are physically limited to 3 drives and one arm. If you have the NETBAY3 you can run up to 6 drives with 3 on each channel, or with all 6 on one channel. To go beyond that you are going to be looking at something like the EXP300 or 500 expansion bays. If you don't have the NETBAY3 I would get one, and then get the store on a different arm/channel. Here are your choices as I see them from the top of my head. using a NETBAY3; 1 channel and 3 raid 1 drives, then you could do os, logs, and store on separate drives however you are still going to take a performance hit because they are all on the same channel. 2 channels 1- Raid1 drive and 2 logical drives on 1 channel for the OS and Logs 1- Raid1 drive with 1 logical drive for the store. Not the optimum, however you will at least get your logs and store on separate drive arms. I had this for a couple of years and it worked fine. Get yourself an EXP unit; 1-Raid 1 in the server for the OS 1-Raid 1 in the EXP for the logs 1-Raid 5 in the EXP for the stores The EXP is a duel channel bus, this would put your OS, Logs and Store all on separate channels and give you the best performance. What I have done for our severs is run both the NETBAY3 and an EXP500, this allows me to run two channels within the servers, and split the EXP between two servers. -----Original Message----- From: Gonzalez, Alex [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 18, 2002 3:07 PM To: Exchange Discussions Subject: RE: Hard Drive Utilization Oh it's a 86565RY. -----Original Message----- From: Waters, Jeff [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 18, 2002 2:14 PM To: Exchange Discussions Subject: RE: Hard Drive Utilization Sorry brain dead, I missed the netfinity part. What server are you running this in? If you have the IBM raid manager loaded you can run that within windows, otherwise you either run the config or open the box up. Your server configuration is going to determine how the drives are setup. If you get me the model of IBM server you have I can give more information. I know the 4M card very well as we have a few of them here. -----Original Message----- From: Gonzalez, Alex [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 18, 2002 2:15 PM To: Exchange Discussions Subject: RE: Hard Drive Utilization well we have a multi channel card but how do I do this now that everything is configured this way? -----Original Message----- From: Waters, Jeff [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 18, 2002 2:07 PM To: Exchange Discussions Subject: RE: Hard Drive Utilization sorry I missed the other post. That is your problem, you really, really, really need to get a multi-channel Raid card, the put the OS, Logs, and store on separate arms. Until then you performance is only going to get worse. -----Original Message----- From: Gonzalez, Alex [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 18, 2002 2:11 PM To: Exchange Discussions Subject: RE: Hard Drive Utilization No everything is on the same RAID. We have Blackberry Server edition but that barely does anything we only 5 people using it. Also we have Norton AV but I have shut that off and it still runs hot. Only the drives though the processor only runs at like 20% -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 18, 2002 2:04 PM To: Exchange Discussions Subject: RE: Hard Drive Utilization Are logs and db on same raid 5 set? Logs should always be on Raid 1 and db on raid 5 (in an ideal environment). Logs are sequential I/O's where DB's are random I/O's. Are there other applications other than exchange running on the server? Are backups taking place at the same time (i.e. peak business hours)? -----Original Message----- From: Gonzalez, Alex [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 18, 2002 2:00 PM To: Exchange Discussions Subject: RE: Hard Drive Utilization Netfinity Ultra 160 4M.

By that I mean speed not actually how large. Are box runs very slow and the hard drives look peaked.
