EF5XX solid state disk drive including the data retention
system, the Digital Storage System Interconnect (DSSI)
bus function, performance features, specifications, shipping
contents, and related documents.
Chapter 2 ‘‘Installation Overview’’ describes how to prepare the EF5XX
disk drive for installation and how to install the EF5XX into
the BA400-series system and SF7X storage enclosures.
Chapter 3 ‘‘Controls and Indicators’’ describes the controls and indicators
used to operate the EF5XX disk drive and how to assign the
DSSI node ID.

Introduction, Continued
Chapter 4 ‘‘Local Programs’’ describes how to access local programs
through the:
 VMS system and the console by using the SET HOST/DUP
command
 MicroVAX Diagnostic Monitor (MDM)
Chapter 5 ‘‘Data Retention System’’ discusses integrated data retention
system features including battery testing and monitoring.
Chapter 6 ‘‘Troubleshooting Procedures’’ describes the internal self-tests
the EF5XX Integrated Storage Element (ISE) conducts and
what to do if the EF5XX disk fails to operate correctly.
Conventions The term EF5XX refers to the EF51R, EF52R, or the EF53 solid
state disk drive.

Overview, Continued
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.

Using the
EF5XX You can use the EF5XX-series ISEs with these VAX family
systems:
 VAX4000
 VAX6000
 VAX7000
 VAX10000
EF5XX
Options These are the EF5XX ISEs covered in this guide and their
formatted storage capacities:
 EF51R, 107 megabytes
 EF52R, 205 megabytes
 EF53, 267 megabytes
Data
Retention
System
Description
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 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
ISE 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.

Performance
Features 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:
Table 1–1 EF5XX Series Performance Features
Feature Function
Multihost support This allows a single ISE to be used by more than one host
at the same time. For example, two VAX4000 systems
can be booted from a single ISE.
670-bit Error
Correction Code
(ECC)
EF5XX ISEs store a large, 670-bit ECC in each block,
capable of correcting up to 320 erroneous bits.
Controller-
initiated Bad
Block Replacement
(BBR)
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.
Replacement
Control Table
(RCT) Cache
DSSI ISEs cache the RCT allowing replaced blocks to
be located without the time required to access the RCT
stored on the media.

1"Normal maximum" indicates the maximum power and current under normal
conditions with heavy drive activity occurring.
2"Peak maximum" indicates the maximum power and current under peak
conditions with heavy drive activity occurring. With the EF51R and EF52R,
peak power occurs during the first half hour of fast charge after full discharge.
With the EF53, peak power occurs during self-test, which happens during the
first two minutes of operation.
