Description
The EF5XX series is Digital Equipment Corporation’s first
generation of solid state disk drives packaged in a full-height,
5¼-inch form factor. These DSSI ISEs supply highly reliable
data storage using semiconductor memory as the storage media.
Like all DSSI ISEs, the EF5XX-series disks communicate with
the host using Digital Storage Architecture (DSA) and Systems
Communications Architecture (SCA) protocols such as the Mass
Storage Control Protocol (MSCP). EF5XX-series disk drives
retain the familiar packaging, control panel, diagnostics, and
utilities of the RF series ISEs.

Description
You can use the EF5XX-series ISEs with these VAX family
systems:
VAX4000
VAX6000
VAX7000
VAX10000
These are the EF5XX ISEs covered in this guide and their
formatted storage capacities:
EF51R, 107 megabytes
EF52R, 205 megabytes
EF53, 267 megabytes
The EF51R and the EF52R ISEs provide non-volatility of data
by a data retention system including:
Power sensing logic
An internal winchester magnetic disk drive
A battery to power the EF5XX while dumping data to the
winchester disk
For more detailed information on data retention, refer to
Chapter 5.

DSSI Bus
Function
ISE
The DSSI bus is a logical equivalent to the CI bus used on
larger Digital systems. The DSSI bus is used with low-end and
mid-range VAX systems.
The DSSI bus is a 50-conductor cable that allows one or more
hosts to communicate directly with storage devices. The hosts
and devices communicate through the SCA protocols. As many
as eight nodes (integrated storage elements and adapters) can
connect to one DSSI bus.
The DSSI bus located:
Inside an enclosure may be a flat ribbon cable or a round
bundle of twisted pairs
Between enclosures is a shielded, round cable
approximately one-half inch in diameter
An ISE is a DSSI device that contains an:
Embedded, intelligent controller
On-board Mass Storage Control Protocol (MSCP) server
Each ISE executes commands and transfers data independently
of other ISEs attached to the DSSI bus. Commands and data
are transferred over the DSSI bus in small packets, allowing
multiple ISE transfers to simultaneously complete successfully.

EF5XX-series disks offer powerful performance features that
are not typically available on disk storage devices in this form
factor. Table 1–1 lists some of these features:

(RCT) Cache
at the same time. For example, two VAX4000 systems
can be booted from a single ISE.
EF5XX ISEs store a large, 670-bit ECC in each block,
capable of correcting up to 320 erroneous bits.
With controller-initiated BBR, the ISE presents the
host with a set of logically contiguous blocks, and
disk capacity does not decrease because bad blocks
are detected and automatically moved to spare blocks.
DSSI ISEs cache the RCT allowing replaced blocks to
be located without the time required to access the RCT
stored on the media.

Installing into the BA400-Series Enclosure
Preparing
for the
Installation
To prepare for the installation:
CAUTION
Static electricity can damage integrated circuits.
Use the antistatic wrist strap and antistatic pad
found in the static-protective field service kit
(29-26246-00) when you work with the internal
parts of a computer system.
Handle the ISE with care. Dropping or bumping the
ISE can damage the disk surface.
1. After the system manager shuts down the operating system,
set the lock of the enclosure to the bottom position to open
both the top and bottom enclosure doors.
2. Set the enclosure power switch to off (0).
3. Always install ISEs working from right to left.
NOTE
The first or rightmost mass storage cavity in
the mass storage area is wider than the rest to
accommodate a larger device such as a tape
drive. A small filler panel (70-27414-01) is used
to fill the gap when an EF5XX ISE is installed in
this first cavity.
4. Loosen the captive Phillips screw at the top of the blank
ISE front panel assembly and remove the panel.
Before installing an EF5XX-series ISE into a BA400-series
enclosure, you must first remove the skid plate, explained in
the next section.

Installation
Steps
To install the ISE into the BA400-series enclosure:
1. With the side that had the skid plate attached to it facing to
the right, slide the ISE along the guide rails into the mass
storage cavity (Figure 2–2A).
2. Using the upper and lower finger cutouts on the ISE
brackets, firmly push the ISE brackets until the interface
card at the rear of the ISE plugs into its backplane
connector. The guide tabs on the upper and lower brackets
should line up with the cutouts in the chassis. Tighten the
two captive screws (Figure 2–2A).
CAUTION
It is normal to have a small gap between the ISE
mounting bracket tabs and the enclosure frame.
Tighten the captive screws only until they are
securely fastened (9 inch-pounds). Do not try to
force the tabs to fit flush against the frame.
3. Plug the remote front panel cable(s) into the connector(s)
inside the ISE front panel (Figure 2–2B).
Use Velcro on the cable and on the inside of the ISE front
panel to secure the remote front panel cable.
4. Attach the ISE front panel to the enclosure by first fitting
the panel’s lower tabs into position. Fit the panel into
position and secure the panel with its single captive Phillips
screw (Figure 2–2D).
