AIX Storage Management

and that is the library. Optical and tape libraries provide the capability to store

many tapes or optical cartridges within a managed library, such that when a

request for a particular piece of data arrives, the library knows which tape or

optical cartridge the information is on, and can then utilize robotics to select the

item and load it into the tape or optical device. Libraries are discussed in more

detail in 2.2.3.2, “Selecting the Correct Tape Storage Devices” on page 38 and

2.2.4.2, “Selecting the Correct Optical Storage Devices” on page 43.

Thus the three major criteria from a hardware point of view, are the performance

of the storage subsystem, or more generally, it′s throughput, the maintenance of

the required level of availability of the ...
