Library Capacity
Table 1 on page 20 lists the library storage capacities. Although library
capacity is automatically configured when you bring the library online, check
the operator panel to be sure that the capacity information is accurate.
Note HP is transitioning the HP Surestore Tape Library Model 20/700
(product number A5597A) to allow for a new feature. This
feature will make it possible to couple two 20/700 libraries
together, allowing tape cartridges to be exchanged between the
libraries. As a result, we are transitioning to a new product
number, A5597B. Until this feature is available and installed, the
display on your library status screen will continue to identify the
library as “A5597A”. In the future, if you choose to use this
feature, your library will then be identified as “A5597B”.
To determine whether your library is an A5597A or A5597B,
refer to the regulatory label on your unit.
