I'm trying to locate a good resource for creating hot swap capable servers with FreeBSD and Vinum. Specifically, I'm trying to find out several things: Are there resources somewhere that document this type of thing? Please? Do I need controllers for SATA/SCSI that will handle the plugging/unplugging of drives, or do I just need to do a bus rescan (or the like) after the change and notify vinum? i.e. do i need something like an adaptec 2200S or will a 39320 work? Is there anything in particular I should look for when buying hot swap chassis? Other than SCA for SCSI? What about Hot swap with Fibre Channel? What about using FreeBSD in a SAN where it's both serving drives and acting as a client? Where can I find (recent) performance numbers for raid 0,1,5 comparisons? What else should I know about this before attempting it? Thank you. -Stephen
