TS3500/TS4500 Tape Library attachment

Edit online

A TS7770 Tape Attach or TS7760 Tape Attach 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. The tape drives must reside in either Model L22, L23, D22, or D23 frames in the tape library. Each frame can contain up to 12 3592 Tape Drives.

Communication, control, and data signals travel along Fibre Channel connections between the TS7700 and tape drives contained in the TS3500 or TS4500 Tape Library. A pair of Fibre Channel switches within the frame that contains the 3953 L05 Library Manager routes the data to and from the correct tape drive.
Notes: FC 0203, 50-micron LC/LC 31-meter provides a 50 micron, 31 m fiber cable for connection between the fiber switch and the TS7700.

The distance between a TS3500 or TS4500 Tape Library that is attached to a TS7700 should not exceed 30 m (98.43 ft.). Although the length of Fibre Channel cables that are provided by FC 0203 is 31 m (101.71 ft.), the remaining 1 m (3.28 ft.) length is required to complete attachments within the frames.

To ensure correct operation of 3592 Tape Drives in a TS3500 or TS4500 Tape Library that is attached to the TS7700, you must:
  • 32Gb FC switches will be installed in the TS7700.
    Note: Microcode 8.54.1.xx and later supports 32Gb switches.
  • Designate four 3592 Tape Drives as control paths by using the tape library management GUI.
  • Install either a Model L22 and a Model D22 frame, or a Model L23 and a Model D23 frame, or a combination of L- and D- Model frames if you want automatic log capturing.
  • If using a 16 Gb Fibre Channel switch, verify that the ports for the 3592 Tape Drives are set up as Auto (N), not Auto (L).
  • If using a 32 Gb Fibre Channel switch, verify that the ports for the 3592 Tape Drives are set up as Auto (N), not Auto (L).
