DISCLAIMER
Failure of the MAA31xxxx, MAB30xxxx and MAC30xxxx series intelligent disk drive is defined as a
failure requiring adjustments, repairs, or replacement. Fujitsu is not responsible for drive failures
caused by misuse by the user, poor environmental conditions, power trouble, host problems, cable
failures, or any failure not caused by the drive itself.
The suffix of the model name of the disk drive varies depending on the electrical requirements,
capacity, and data format at factory shipment of the SCSI, i.e., the interface for connecting the three
device types or host system and the disk drives (Note 1). However, in this manual, the typical model
names (Note 2) are used unless otherwise noted. These disk drives may be called intelligent disk
drives (IDD), drives, or devices in this manual.

CHAPTER 1
GENERAL DESCRIPTION
1.1 Standard Features
1.2 Hardware Structure
1.3 System Configuration
This chapter describes the feature and configuration of the intelligent disk drives (IDD).
IDDs are high performance large capacity 3.5-inch fixed disk drives with an embedded SCSI
controller.
The interface between the IDD and host system is based on SCSI (Small Computer System Interface)
standard [ANSI X3.131 - 1986: Small Computer System Interface (SCSI), ANSI X3.131-1994: Small
Computer System Interface - 2 (SCSI-2)].
The flexibility and expandability of the SCSI, as well as the powerful command set of the IDD, allow
the user to construct a high-performance reliable disk subsystem with large storage capacity.
C141-E035-01EN
1 - 1
1.1
Standard Features
(1)
Compactness
Since the SCSI controller circuit is embedded in the standard 3.5-inch fixed disk drive form
factor, the IDD is extremely compact. The IDD can be connected directly to the SCSI bus of
the host system .
(2)
(3)
(4)
SCSI/CCS standard
The IDD provides not only SCSI basic functions but also the following features:
·
·
·
·
Arbitration
Disconnection/reselection
Data bus parity
Command set which meets the logical specification of the SCSI CCS (Common
Command Set for Direct Access Device) requirements (Rev. 4.B)
The SCSI commands can manipulate data through logical block addressing regardless of the
physical characteristics of the disk drive. This allows software to accommodate future
expansion of system functions.
8-bit SCSI/16-bit SCSI
The IDD has 16-bit data width (16-bit SCSI), which have the wide transfer function suitable
for SCSI-3.
·
·
8-bit SCSI: Up to eight SCSI devices can be connected on the same SCSI bus.
16-bit SCSI: Up to 16 SCSI devices can be connected on the same SCSI bus.
For the ultra SCSI model, number of connectable SCSI devices on the same SCSI bus is varied
as follows.
·
·
Up to 4 SCSI devices having capacitance of 25 pF: Cable length of up to 3.0 m.
5 to 8 SCSI devices having capacitance of 25 pF: Cable length of up to 1.5 m
High speed data transfer
·
·
8-bit SCSI:
The data transfer rate on the 8-bit SCSI bus is 6 MB/s maximum in
asynchronous mode, 20 MB/s in synchronous mode.
16-bit SCSI: The data transfer rate on the 16-bit SCSI bus is 12 MB/s maximum in
asynchronous mode, 40 MB/s in synchronous mode.
Such a high data transfer rate on the SCSI bus can be useful with the large capacity buffer in
the IDD.
1 - 2
C141-E035-02EN
Note:
The maximum data transfer rate in asynchronous mode may be limited by the response
time of initiator and the length of SCSI bus length. The maximum data transfer rate in
synchronous mode on the single-ended SCSI bus may be limited by the cable length,
transmission characteristics of the SCSI bus and the connected SCSI device number.
(5)
Continuous block processing
The addressing method of data blocks is logical block address. The initiator can access data
by specifying block number in a logically continuous data space without concerning the
physical structure of the track or cylinder boundaries.
The continuous processing up to [64K-1] blocks in a command can be achieved, and IDD can
perform continuous read/write operation when processing data blocks on several tracks or cylinder.
(6)
512 KB programmable multi-segment data buffer
Data is transferred between SCSI bus and disk media through the embedded 512 KB data
buffer in the IDD. This buffer can be divided into maximum 16 areas. This feature provides
the suitable usage environment for users.
Since the initiator can control the disconnect/reconnect timing on the SCSI bus by specifying
the condition of stored data to the data buffer or empty condition of the data buffer, the
initiator can perform the effective input/output operations with utilizing high data transfer
capability of the SCSI bus regardless of actual data transfer rate of the disk drive.
(7)
(8)
(9)
Read-ahead cache feature
After executing the READ command, the IDD reads automatically and stores (prefetches) the
subsequent data blocks into the data buffer (Read-ahead caching).
The high speed sequential data access can be achieved by transferring the data from the data buffer
without reaccessing the disk in case the subsequent command requests the prefetched data blocks.
Command queuing feature
The IDD can queue maximum 128 commands, and optimizes the issuing order of queued
commands by the reordering function. This feature realizes the high speed processing.
Recordering algorithm is adopted to prevent a specific command from staying in a queue for
more than 3 seconds.
Reserve and release functions
The IDD can be accessed exclusively in the multi-host or multi-initiator environment by using
the reserve and release functions.
C141-E035-03EN
1 - 3
(10)
Error recovery
The IDD can try to recover from errors in SCSI bus or the disk drive using its powerful retry
processing. If a recoverable data check occurs, error-free data can be transferred to the
initiator after being corrected in the data buffer. The initiator software is released from the
complicated error recover processing by these error recovery functions of the IDD.
(11)
(12)
(13)
Automatic alternate block reassignment
If a defective data block is detected during read, the IDD can automatically reassign its
alternate data block.
Programmable data block length
Data can be accessed in fixed-block length units. The data block length is programmable, and
can at initializing with a multiple of two for the 512 to 528 bytes.
Defective block slipping
A logical data block can be reallocated in a physical sequence by slipping the defective data
block at formatting. This results in high speed contiguous data block processing without a
revolution delay due to defective data block.
(14)
(15)
High speed positioning
A rotary voice coil motor achieves fast positioning.
Large capacity
A large capacity can be obtained from 3.5-inch disk drives by dividing all cylinders into
several partitions and changing the recording density on each partition (constant density
recording). The disk subsystem with large capacity can be constructed in the good space
efficiency.
(16)
(17)
Start/Stop of spindle motor
Using the SCSI command, the host system can start and stop the spindle motor.
Diagnosis
The IDD has a diagnostic capability which checks internal controller functions and drive
operations to facilitate testing and repair.

(20)
1.2
Low power consumption
By using highly integrated LSI components, the power consumption of the IDD is very low,
and this enables the unit to be used in wide range of environmental conditions.
Low noise and low vibration
Approx. 4.2 bels for the IDD. This makes it ideal for office use. The IDD has rubber
vibration isolators, which minimize the transfer of vibration.
Microcode downloading
The IDD implements the microcode download feature.
maintainability of the IDD and function enhancing.
This feature achieves easy
Hardware Structure
An outer view of the IDD is given in Figures 1.1 to 1.4. The IDD is composed of the disk,
head, spindle motor, hermetically sealed disk enclosure (DE) with actuator and air circulation
filter, as well as read/write pre-amp with the print card unit (PCA) of the controller.
