The T401 is a 1/2–inch cartridge tape drive with 18 data recording tracks.

The tape speed is 2 m/s with a data transfer rate of approximately 370 KB/s

fromsystemtoformatterunderVOS10.2(450KB/sunderVOS11.0). The

T401 is available in two configurations: single and dual drive assemblies.

•Utilizesan automaticloader, which holds up to 10 car-

tridges, on each drive assembly.

•Has a storage capacity of 200 MB per cartridge (2 GB

per drive assembly).

•Uses a Formatter (Controller) with a SCSI interface

connecting to a K122 IOA (K116 for initial release).

•Employs current tape commands and can be used as a

boot device.

•Has built–in comprehensive self–diagnostics.

•No operational maintenance required except periodic

Each T401 model contains a single Formatter unit that controls the transfer

of read/write data commands between the Stratus processor and the tape

drive. In the 1x2 model, the Formatter controls both drives which are

connected in daisy chain.

A control data cable (digital), which transfers the command and write data,

is connected from the Formatter to the first (or only) drive which is Drive 0.

A read data cable (analog) is also connected from the Formatter to Drive 0.

A dc power control cable is connected from the PCI connector on the

Formatter to the PCI connector on the Drive 0 power supply. A SCSI cable

is connected from the SCSI IN interface on the Formatter to the K122 IOA

and a terminator is installed on the SCSI OUT interface. In the 1x2 model,

the second drive (Drive 1) is daisy chained to the first by connecting a

second power control cable from the PCO connector on the Drive 0 power

supply to the PCI connector on the Drive 1 power supply.

6T401 Tape Drive Installation Instructions

The T401 Tape Drive is factory–installed in one of the expansion cabinet

configurations shown earlier. The expansion cabinet is fitted with a special

external door extension frame to accommodate the auto loader(s) on the

Drive Assembly. An access door in the top of the extension frame opens

upward to allow insertion of a cartridge magazine in the autoloader. The

cabinet unpacking and installation procedures are the same as for any

Stratus universal cabinet. Follow the instructions in the Universal Cabinet

Announcement Bulletin (HA–002050) and the Stratus 40–Slot Systems

Installation and Operations Guide (HI–001030).

If the K122 IOA is located in a different expansion cabinet, route the SCSI

cable from the Formatter through the plenum using the procedure for

routing I/O cables found on page 12 in the Universal Cabinet

Announcement Bulletin.
