Depending on the size of your disk storage pool.... the speed of the tape
subsystem throughput may be irrelevant in ADSM. The data could go directly
to disk.
We have SSA disk on a AIX Sp2.

With AIX as a server, I find the network interface is the critical factor.
(from coaxial Ethernet connecting a desktop on a busy network to SP2 high
speed switch or shared memory)
The difference of the interface speed in our shop is in the range of 1000
times or more.
