...Michael, I like the boot from SAN idea, do you do that?. Our intel guys don't seem keen, saying there are performance problems. Seems to me it would give the slickest failover though...
Never used it myself.
I would ask whoever said there are performance problems for more info about why they are saying that. Did they actually try it themselves? Or did they just hear it somewhere, and are repeating an old wives tale based on some problems with early versions, etc.? Also, even if they did try it themselves, did they really know what they were doing?
Doesn't hurt to be a little skeptical. Of course, that also includes the promises made by SAN vendors with visions of of multimillion dollar sales.
We already have the SAN and SRDF with it, both are already used for fileservers and app servers etc, so perhaps the experience with boot from SAN comes from that. Whatever I will include that setup in the POC. The powers that be have said they want SRDF used for the SQL servers and if we are going to go that route (and I'm quite happy to) I'm just really smitten by the idea of being able to replicate the whole server so failover becomes flip the drives and boot the server up, no worrying about hardcoded server names or file locations in databases, SSIS packages etc. I maybe being too optimistic.
