Not the best configuration if OS and data are mixed so I can see your concern there, but you wouldn't be the first organization that has run like that. You can probably get away with that config for awhile, depending on how your performance metrics come back. With your 3 to 4 day recovery requirement a hot spare and a good warranty will do the trick =)
Having said that, buying 2 cheap 1u servers with mirrored disks to serve as DC's isn't a bad idea. You could then talk to Dell about adding disks and/or a JBOD enclosure and more disks to the existing box and use it as a dedicated file server. -Jeff Steward On Thu, Sep 23, 2010 at 4:24 PM, John Aldrich <[email protected]>wrote: > 3 Disk RAID 5, I believe.
