We are doing Boot-to-SAN on about 30 production servers right now without a single problem or performance glitch. The idea spooked me also, but we extensively test and load simulated the setup in the lab and it proved to be very solid. We even have 2 production SQL servers running b00t-to-SAN and they are 2 of our best performing database servers.
Technology moves forward and I guess we must move with it, sometimes :P. -tOny -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fyodorov, Andrey Sent: Friday, January 09, 2004 11:00 AM To: Exchange Discussions Subject: RE: Location of Transaction Logs Boot-from-SAN thingie kind of spooked me, but maybe because I have never been in an environment that used it. -----Original Message----- From: Roger Seielstad [mailto:[EMAIL PROTECTED] Sent: Friday, January 09, 2004 1:44 PM To: Exchange Discussions Subject: RE: Location of Transaction Logs Yo, Tony! I see you survived the trip back from Orlando... If I remember correctly, you can bypass caching at the RAID group (not the LUN) level through Navisphere. I don't currently have access to mine to check, but I know I asked that question. Another option is to change the read/write cache percentage to be mostly read caching and reduce the potential exposure. I'd suggest skipping boot-from-SAN, but that's just me. The only reason I'd see boot-from-SAN helping is if you are going to have identical cold standby hardware available to replace in the case of system failure. I'm not sure you want to use non-identical hardware for cold spares in that kind of case. Roger -------------------------------------------------------------- Roger D.
