If your installation is going to use optical, tape, or both types
of storage, you must estimate the amount of optical disk and tape
cartridge storage that you need for your OAM implementation. Factors
to consider should include the number of the following:
- Optical libraries required per day
- Optical disks, tape cartridges, or both required per year
- Shelf-resident optical disks, tape cartridges, or both
- Optical, tape, or both types of libraries
- Operator-accessible optical disk drives
- Tape stand-alone drives, ATLDSs, and MTLs, or a combination of
these devices
This section provides techniques for calculating optical and tape
space requirements based on these considerations. See Optical resources for
an example of how these computations are applied.
