We use IBm Shark disk for our TSM staging pools. One raid set in the
Shark (8 drives, raid5) can accept sequential data at 30MB/s
continuously. We send 2 gigabit data streams to disk over night at
60-70MB/s. Most of our data is already compressed Oracle backups, so
when we destage the disk pool we drive 8 3590E drives at 80-90MB/s.
We have lots of EMC storage. When using meta-volumns we can drive
them at about the same rate for sequential writes - about 30-35MB/s.
