## 7.1.4 TS7700 tape library attachments, drives, and media 

In TS7700 configurations, the TS7760T and TS7770 are used with an attached tape library. The TS7760T and TS7770 must have their own logical partitions (LPARs) within the TS3500 or TS4500 tape library, with dedicated tape drives and tape cartridges. 

## Tape libraries 

A TS7760T or a TS7770 attached to a TS3500 or TS4500 tape library interfaces directly with tape drives in the library. 

When attached to a TS3500 or TS4500 tape library, the TS7700 can attach only to 3592 Tape Drives. Up to 16 3592 Tape Drives can be attached. 

Communication, control, and data signals travel along Fibre Channel connections between the TS7700 and tape drives that are contained in the TS3500 or TS4500 tape library. A pair of Fibre Channel switches routes the data to and from the correct tape drive. 

Note:  TS1140 EH7 tape drives and TS1150 EH8 tape drives are used with the TS4500 tape library. All other tape drives are used with the TS3500 tape library. 

## Tape drives 

The 3592 Tape Drives supported for use with the TS7760T and TS7770 include:
