Are you really comparing equal systems? 8gbit Fibre Channel means a
single Fibre Channel shared by 42 disks, whereas 3GBit DAS SAS
means 42 3gbit channels running in parallel.

Unless you want to spend *A LOT* of money, DAS is the way to go. You
While I agree with JD, we ended up using a fiber solution through a fiber
switch with multi-path drivers (IBM DS4300). It did end up costing a few
thousand dollars with all of the drives, but the performance made it worth it.

With the right supplier, you can plug in literally 100 hard drives to

The first is 8gbit Fibre Channel, the last is 3Gbit DAS SAS. The
