[OpenAFS] openafs fileservers in VMware ESX

[ted creedon]

Here I just move my raid card and 4 drives.

Linux 2.6 doesn't have support for the older IDE raid cards. New systems
have soft raid which allows a drive only move. Its particularly easy with
sata drives.

I agree.  I've never understood the "big honking box" syndrom.  It has
always seemed to me to be an indication of "Pointy Haired Bosses" being
marketed to that causes this situation.  The point of AFS is speed,
distribution, and scaleability, but you also get redundancy.  Putting an AFS
cell on a virtualized server is just IMHO...silly.  I can't see how in the
long run you save money with specialized boxes when server PCs from DELL,
which can be used for AFS file servers, cost less than $500 a pop.  Of
course if you go rack mount, things get more pricey, but still, compared to
some specialized box from a proprietary vendor?
