If anyone has access to an Xserve, can you do one thing for me? Open the disk utility (or whatever controlls RAID setup now) and see if it supports anything other than RAID levels 0 and 1. Rumor has it the Xserve is supposed to support RAID 0+1 and RAID 5 and perhaps others (I'd really like to see 10). But perhaps this won't happen till OS X 10.2. Any clear info on this would be greatly appreciated!! Also, if you notice anything else in the Xserve that's different from regular OS X 10.1.5, that would be nice to know too. For example, Apple has said that an Xserve can boot from an Apple RAID, which can not be done with a regular Mac. Also Xserves can run headless. Anything else? TIA!
