Announcing DLT8000 Differential Tape Support on MPE/iX

By Tina Wang, CSY Labs and

Dave Black, MPE/iX Expert Center

MPE/iX now supports the following Differential DLT Tape drive (this is in addition to the

previously announced DLT4000 and DLT7000):

Software Requirements

Customers wishing to use this new DLT device must be running on either MPE/iX 5.5 or

6.0 (and later releases):

• On 5.5 (Release C.55.00, MPE/iX 31900C.05.08, with patch MPEKXU0)

• On 6.0 (Release C.16.01, MPE/iX 31900C.16.01, with patch MPEKXU0)

MPEKXU0 allows the software device driver to recognize the vendor ID or the support of the

DLT8000.

The DLT8000 is not supported by Predictive.

Hardware Requirements

On HP 3000 S900 systems F/W SCSI Device Support is typically provided via the 28696A

NIO F/W SCSI Device Adapter Card. At the time this article was written there are two

other possible F/W SCSI Device Adapter Cards. NEITHER of these connection options is

actually supported:

Unsupported connection Option #1

The 9x9KS Core I/O Card A3453-69210 exports a F/W SCSI interface.

However we do NOT, for performance reasons, support or recommend that

a DLT be connected via this interface. The assumption is that this

exported bus will also be shared with the system’s internal Disks and

unpredictable and unacceptable performance may be seen when disks and

DLT are accessed simultaneously (as during STORE/RESTORE). (Please

read additional information in the Product Overview section for details on

device performance.)

Unsupported connection Option #2

The HP-HSC F/W DA A2969A is not supported on HP 3000 S900 systems.

This card requires the existence of “Device Adapter” Software that has yet

to be written for MPE/iX.

Physical connection of these devices is accomplished via Fast/Wide/Differential SCSI

Cables such as C2911A, C2924A, C2925A, C2905A, C2911A, C2924A etc.
