I don't think its ever worth the single piece of equipment failing, obviously that's a serious concern. The model of SAN we have been looking at have redundancy built into them so I'm so much worried about the unit failing as a whole. "We" have voiced that but unfortunately money is also a factor and they never think about downtime costs. They want us to start clustering also and they don't want to spend the money on the extra disk and potentially have some of it wasted.
These are some of the problems you have when people other then the network/servers people are making the roadmap. Either way they have their hearts set on going to SAN. We will probably avoid putting our network servers(AD, DNS, AV, etc,.) on the SAN but almost all the SQL/Oracle, Exchange, and file server stuff will go there. Pretty much anything they want us to cluster. We do have all our mainframe stuff on its own SAN, for some reason they don't like the network people touching it. Even before I started working here, old territorial boundaries I guess. -----Original Message----- From: John Allhiser [mailto:[EMAIL PROTECTED]] Sent: Friday, December 06, 2002 9:43 AM To: Exchange Discussions Subject: RE: the IBM Shark Yeah. That's why I mentioned the mainframe aspect. I'm not too keen on running large portions of our AD forest on it. There was a murmuring among key higher-ups here to do the same thing while running vmware on mainframe LPARs. That was nipped in the bud after we (network/server people) presented a cost comparison analysis on servers and MS licensing vs. vmware, *nix, et cetera. Eric, your talking about just the storage/access aspect. It comes down to a question of whether the initial savings is worth the potential problems of a single piece of hardware handling multiple critical services. -----Original Message----- From: Schwartz, Jim [mailto:[EMAIL PROTECTED]] Sent: Friday, December 06, 2002 10:01 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]
