First we don't know if you have 8 internal disks, 18 internal disks, or
42 internal disks. We don't know if they are 10K spinny disks, 15K
Spinny disks or SSDs.
We don't know how many processors you have or how much memory you have.
We don't know how much data you have.
We don't know if you have 5 ginourmous Db2 tables eating 80% of your
disk or if you have 25 million objects in the IFS using up that storage.
We also don't know if the Cybernetics unit is the very smallest with
only 4 drives or a 4U behemoth with 36 drives in there.
HOWEVER the rule of thumb is that for a single partition system a SAS
connection will do just fine and will do so a fair bit cheaper than will
a fiber attached one.
