Adding Mixed-Media Storage Cell Capacity
If your needs have increased, you can increase the storage cell capacity and the number
of tape drives in the library. TABLE 1-2 lists how many storage cells and tape drives
can be gained by adding each Drive Expansion Module. The expansion modules are
installed into the same rack as the existing modules.
You can also add a redundant power supply. Contact your marketing representative.
