Below are the results from a test Sun ran using their new 2nd generation CMT based systems (T series) for a NBU media server compared to their UltraSPARC VI based system. There are many advantages to the CMT systems including acquisition costs, power and cooling and space.

At a large Financial customer, we tested the T5220 against the our M5000 server. Here are the results of that test:
M5000 server with 10 T10K tape drives: 940 MB/s sustained throughput, 40 % CPU, $195/MB/sec
T5220 config #1 with 10 T10K tape drives: 940 MB/s sustained throughput, 25 % CPU, $65/MB/sec
T5220 cinfig #2 with 16 T10K tape drives: 1700 MB/s sustained throughput, 40 % CPU, $37/MB/sec
T5220 config #3 with 10 T10K tape drives: 1120 MB/s sustained throughput, 40 % CPU, $55/MB/sec
