Hardware Requirements
TurboSTORE/XL II works with any hardware configuration supported by the
MPE XL system.
Minimum Hardware Requirements
To take advantage of the faster backup features of the TurboSTORE/XL II
program, it is recommended that you have the minimum hardware
configuration:
* At least two tape drives. You can use any combination of HP 7978,
7979, 7980, or 7980XC drives.
* If you use digital audio tapes (DATs), then all devices used for a
STORE must be DATs. You cannot mix DATs and magnetic tapes in a
STORE configuration.
* If your backup devices are used as sequential devices only, then
they can share an HP-IB device adapter.
* If your backup devices are used as parallel devices or parallel
device pools, then each will require its own HP-IB device adapter.
Optimum Performance Hardware Requirements
Although the above hardware requirements are sufficient to achieve a
performance gain using TurboSTORE/XL II, as compared to the standard
STORE program, your system configuration should include the following
elements for maximum effect:
* Three or more tape drives in any combination of HP 7980s or
7980XCs.[REV BEG]
* HPC1501A or HPC1511A DDS-format devices. Do not mix with magnetic
tape devices or DASS devices for a single STORE operation.
* HPC1700A DASS device. Do not mix with magnetic tape devices or
DDS-format devices for a single STORE operation.[REV END]
* HP 7937 or other HP-supported fiberlink disks connected to at
least one HP-FL (fiberlink) device adapter. If HP-IB disks are
used, they should be spread over at least four HP-IBs.[REV BEG]
* Use a maximum of two HP-FL device adapters per channel.
* Do not mix HP-IB, HP-FL and HPCS device adapters on the same
channel.[REV END]
* Do not use more than three HP-IB device adapters per channel.
