Wondering about this.

when no raid and goal=2, this would mean when using multiple disks per
server that each disk would be a seperate chunk location.

Can see the use of this when you use 1 single server as each copy would
reside on 2 seperate disks so you are somewhat protected against disk
failure.

but when you have 2 servers with each 12 disks (24 chunk locations),
does each chunk reside on 2 seperate servers giving protection against
server failure?

did read somewhere there is work done on "location awareness" spreading
each chunks over racks
