VL1-250-SC-DS Introduction
The VL1-250-SC-DS has been designed to provide a complete disk drive subsystem which is mechanically compatible
with the VMEbus. It has been designed specifically to interface with VMEbus processors with an embedded Ultra 320
SCSI Host Adapter. Together with the processor, a complete system can be installed in only two standard VMEbus sys-
tem slots. The VL1-250-SC-DS provides one or two hard disk drives within the same module making it very convenient
to have fixed data storage. The drives used on board the VL1-250-SC-DS were chosen for their compatibility, rugged-
ness and reliability. The Ultra 320 SCSI bus can be connected to the module via the front panel 68 pin Wide SCSI
VHDCI connector or via the P2 connector.

Features and
Specifications

Scope
This chapter describes the overall features and specifications of the VL1-250-SC-DS .
Features
The VL1-250-SC-DS incorporates one or two very compact winchester disk drives within a single module. The hard
disk drive(s) is a high-performance winchester type with embedded disk drive control electronics. This microprocessor
controlled embedded controller is on the hard disk and is compatible with ANSI X3.131-1986 SCSI commands. The
hard drive is a very high performer, with a 1-to-1 interleave and an average track-to-track access times of 10 millisec-
onds or less. It incorporates an embedded at least 8 megabytes of cache buffer which is operated in “look ahead”
mode, providing buffering for sequential sector operations. The hard drive(s) has been carefully packaged with suitable
control cables and power distribution connectors for direct attachment to single board computers in the VME chassis or
to external devices.
Ultra 320 SCSI Interface Description
In order to provide a method of embedding the disk drive control electronics within the hard disk drive, several disk
drive manufacturers jointly defined an interface specification. This specification for the Small Computer System Inter-
face has become known throughout the industry as “SCSI”. Basically, the SCSI interface consists of the required
address, data and control signals from a wide SCSI Host Adapter. Since a goal of the specification is to allow the disk
drive to be connected via standard cable, the specification required buffering of all signals so that the drive could be
mounted a suitable distance from the board interface. This distance, however, is limited to twelve meters. The specifi-
cation provides all signals via a 68-pin header connector for use with standard 68 conductor ribbon cable and connec-
tors. Table 2-2 is a description of the Ultra320 SCSI pin definitions. The direction indicated is relative to the host.

Configuration, Installation,
and Operation

This page intentionally left blank.

Scope
This chapter describes how to configure, install and operate the VL1-250-SC-DS mass storage subsystem module.
Drive Hardware Configuration
The drives on the VL1-250-SC-DS can be configured for normal operation as SCSI units 0-15 by setting the front panel
switches with a small screwdriver.(See Figure 1-1) The particular configuration of the Unit ID's required depends upon
the software and the application operating system.
Hard Disk Drive Hardware Configuration
The hard drive can be set so that it is activated by the SCSI unit 0-15 ID, as is required to maintain compatibility with the
SCSI software. The hard drive installed on the VL1-250-SC-DS utilizes the Ultra 320 SCSI interface. It is possible to
connect other Ultra 320 SCSI devices via the interface cable and to connect 14 other units to the SCSI interface if need-
ed.
Considerations For Installation
There are several considerations before installing the VL1-250-SC-DS into your system.
VMEbus Slot Requirements
The VL1-250-SC-DS requires one slot in a standard VMEbus 6U card cage. Since there is drives are steel panel cover,
this could potentially cause a shorting problem. If you are going to have a VMEbus card located in the next adjacent slot,
you should carefully check it to make sure that no leads are likely to touch the VL1-250-SC-DS .
VMEbus Backplane Configuration
The VMEbus P1 connector supplies all operating power to the VL1-250-SC-DS and shunts the daisy-chain signals on the
P1 connector. However, no other VME signals are connected on board. Therefore, you must check your VMEbus back-
plane for all daisy-chain signals continuity at the two slot positions occupied by the VL1-250-SC-DS .
Power Supply Requirements
Make sure that your VMEbus power supply has adequate capabilities to support the operation of the VL1-250-SC-DS
when it is installed with all other cards in your VMEbus system. Pay particular attention to the +12 volt power require-
ment. The specifications listed in Chapters 2 and 4 should be consulted for the maximum current requirements. Your
power supply must be capable of providing sufficient current for the hard disk drive motor(s) to spin up during initial oper-
ation (approximately 5 seconds).
Installing the VL1-250-SC-DS
Make sure that all power is removed from the backplane before inserting the boards. Prior to inserting the VL1-250-SC-
DS into the card cage, it is necessary to verify the cable connections to the SCSI host/processor. Once you have con-
nected and properly seated the associated cable assemblies, you should insert the host/processor into the VMEbus card
cage. Now install the VL1-250-SC-DS into the VME chassis and mate the P1 connector properly. The P2 connector
should also be aligned. Then connect the VL1-250-SC-DS to the SCSI host/processor with a 68 pin Micro-D cable or via
the P2 connector on the backplane with the proper Phoenix International adapter module.
Configuration, Installation, and Operation 3-3

Drive Software Configuration
Initially you will need to run a device setup program in order to configure the software and hardware to properly recognize
the drives on the VL1-250-SC-DS . You should consult the host/processor manual and/or operating system manuals for a
description of the utility required to properly format and use your mass storage subsystem.
Hard Drive Software Configuration
The hard disk drive can be installed as SCSI unit 0-15. The disk drive characteristics are described in detail in Chapter 4.
It operates using the Ultra 320 SCSI interface and has to be configured by the host operating system software for proper
operation.
Terminator Power
Terminator power for the drives is routed via cable from the SCSI bus Host adapter. This supplies the Terminator Power
to the unit and the P2 connector pins for Terminator Power.(See Figure 1-2)
Termination
The active termination required for the SCSI-2 bus is on the VX2 module. The SensiTermTM circuitry will automatically
configure the termination for the SCSI bus. It determines if the SCSI bus signals are received from the P2 connector or
from the Micro-D connector on the front panel and sets the termination at the correct end of the SCSI bus. If the module
is in the middle of a SCSI bus route, the SensiTermTM circuitry automatically disables all on board termination.
Operation
Once the VL1-250-SC-DS has been configured properly and the software has been set up, operation is identical to that
of a standard SCSI storage subsystem. No specialized software is required.
