• D14 is designed to attach up to four ESCON/FICON attached 3590 Tape Drives and will store from 275 to 400 tape cartridges.
• D22 is designed to attach up to twelve FC attached 3592 Tape Drives and will store from 230 to 400 tape cartridges
• D24 is designed to attach up to eight FC attached 3592 Tape Drives and will store from 275 to 400 tape cartridges

Tape Storage Frame - S10

Availability Tape Frames (Model HA1)Enterprise High

The Enterprise High Availability Tape Frames (HA1) are designed to ensure you have access to your data even if there is a failure of the library manager or the cartridge accessor. It consists of two service bay units, one placed at each end of the library, plus a second library manager and accessor. The HA1 will operate in hot-standby mode if there is no dual active accessor option.

In the event of a cartridge accessor or library manager failure, the standby accessor and/or library manager will take control of all operations in the library. The model HA1 is designed to eliminate the library manager and the tape cartridge accessor as single points-of-failure.

An optional feature for the High Availability Frame is the Dual Active Accessor. This feature activates the library's second cartridge accessor enabling both accessors to operate simultaneously.

Highlights of the HA1 Model:

• Second library manager
• Second cartridge accessor - single or dual gripper
• Communication between two library managers
• Switching hardware for switching between the two library managers
• Two service bays for storage of the second accessor and service diagnostics for accessor repairs during library operations.

Highlights of the Dual Active Accessor:

• Two active accessors in the same library
• Improved tape mount performance
• Improved cartridge inventory time.
