Good feedback, thank you. Mostly it's a disk cost issue, that's the larger driving issue. Its going to happen, I don't really have a big say there. What I do have a say in is what should go to san and what shouldn't. Sounds like maybe exchange shouldn't.

Several of the failures required Disaster Recovery for the DBs. Strangely it always happened just before I was going on a vacation, which does something bad for Quality of Life if you're married, etc... Vendor replaced just about every single piece of hardware over the various failures. On the last one I DR'd to a JBOD we had laying around and everything has been fine since. A relaxing Thanksgiving. I had great hopes for Snapshotting and other such SAN possibilities, but Exchange doesn't support those natively. And they aren't about to spend the money here for higher end Backup software like Comm Vault, etc... So, that SAN got me nothing in added functionality, just a lot of aborted vacations. YMMV, but what added functionality are you hoping to get from the SAN? Are you sure Exchange/OS will actually support it? And from the other E2K shops I know ... it looks like Clustering one way or the other ends up reducing your reliability and up-time. But, if you're own of those Admins without family or interest in vacations there could be merit in these options.

If you find yourself arguing the difference between spindles and storage space, you're going to have a grand old time. The architecture for the large SAN vendors was based on the limitations in the IBM 3xxx mainframe systems. It was more cost effective to place large amounts of cache in the storage system to accommodate its predictable, read IO operations. You'll find that the typical answer to any issue you have with a large SAN is to throw more hardware at it. -----Original Message----- From: Hansen, Eric [mailto:[EMAIL PROTECTED]] Sent: Friday, December 06, 2002 12:18 PM To: Exchange Discussions Subject: RE: the IBM Shark :p that could be solved with proper planning and good lun management. -----Original Message----- From: Schwartz, Jim [mailto:[EMAIL PROTECTED]] Sent: Friday, December 06, 2002 9:01 AM To: Exchange Discussions Subject: RE: the IBM Shark You're going to carve up the disks and share spindles with "critcal" servers running high intensive databases? <snicker> Good luck. -----Original Message----- From: Hansen, Eric [mailto:[EMAIL PROTECTED]] Sent: Friday, December 06, 2002 10:52 AM To: Exchange Discussions Subject: RE: the IBM Shark We plan on using it for our 17 "critical" servers and to cut the prices of all the disk we have. Mostly Windows/SQL, and some AIX and linux. Out the door we were going to start with 3tb so the rumor of a 3.36tb performance boundary made me a little wary, but I'm not sure if there is any truth to it. e- -----Original Message----- From: John Allhiser [mailto:[EMAIL PROTECTED]] Sent: Friday, December 06, 2002 8:47 AM To: Exchange Discussions Subject: RE: the IBM Shark As DASDI for os390/Zos mainframes they're great. Not aware of the exact performance boundary. What do you plan to use them for. -----Original Message----- From: Hansen, Eric [mailto:[EMAIL PROTECTED]] Sent: Friday, December 06, 2002 9:29 AM To: Exchange Discussions Subject: OT: the IBM Shark Is anyone here happen to be running a IBM shark or possibly a Hitachi 9900 series SAN? We are looking at both of these and I have heard rumors that the shark has a performance boundary of 3.36 TB. Just curious. e- _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
