It's not an SSA array, it's a JBOD in mirror.
I can't give you more machine details alas (customer confidential). The only details I
can give you are:
RS/6000 model F80
2 CPU
1 GB memory
SAP DB size 100GB on SSA disks (JBOD with mirroring)
3584 LTO with 8 LVD drives
TSM server 4.2.1.8
TSM client 4.2.1.15
TDP for R/3 3.2.0.6

You mention 20 MB/sec and that the SAP database is on an SSA array. Well
some SSA array's have a maximum throughput of 20 MB/sec. This depends on the
adapter, and how you have the SSA array configured.
It would be nice to get the machines hardware configuration more completely.
Also have you benchmarked your SSA array to see what maximum throughput it
can sustain. If you are running 8 streams of backup through one SSA
adapter, you could run into contention.
