damages to this product itself or property of other users if the user does not perform the p rocedure correctly.
Work division Preca u tion Page
Assembly/installation
Damage to drive A hole or screw portion as shown in Figure 4.8 is used for adjusting air pressure balance between inside and outside the DE. Do not fill with a seal or label. Seals on the DE prevent the DE inside from the dust. Do not damage or peel off label s .
Damage
1. When dismounting the drive which is mounted on the system while power is supplied to it.
The drive to be dismounted must be separated from the loop. Dismounting the drive which is not separated from the loop may cause a n un expected err or.
If the drive is not separated from the loop, issue an LPB to the drive from the initiator in a primitive sequence of the order set.
It is recommended to stop the spindle motor prior to this loop separation operation. The spindle motor can be stopped by a START/STOP command. It takes about 30 seconds for the spindle motor to stop completely.
Then, dismount the drive using the drive mounting/dismounting mechanism, etc. of the system. If the drive is dismounted while the spindle motor is running, special care is required to avoid excessive vibration or shock to the drive. It is recommended to stop the operation once the SCA connector breaks off contact and wait until the spindle motor stops (about 30 seconds) before dismount the drive.
When storing or transporting the drive, put it in an antistatic bag. (Shown in Section 5.1).
2. When dismounting the drive which is mounted on the system while power is not supplied to it
Do not move the drive until the drive stops completely (about 30 seconds if the spindle motor was stopped by a START/STOP UNIT command, and about 30 seconds after powering-off when the power was simply turned off).
Then, dismount the drive using the drive mounting/dismounting mechani s m, etc. of the system.
When storing or transporting the drive, put it in an antistatic bag. (Shown in Section 5.1).

CHAPTER 1 GENERAL DESCRIPT ION

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).
MAF3364FC and MAG series in telligent disk drives (IDDs) are h igh per forma n ce lar ge cap acit y 3.5-in ch fixed disk drives with an embedded fibre-channel controller.
The in terface between the MAF3364FC/MAG series intelligent disk drives and host system conforms to the fibre channel PLDA stan dard [NCITS TR-19 FIBRE CHANNEL PRIVATE LOOP SCSI DIRECT ATTACH (FC-PLDA] which covers from the fibre channel physical layer to SCSI command protocol.
A combination of the high transfer speed and long-distance transfer of the fibre channel and high function command set of the MAF3364FC and MAG seri es intelligent disk drives will facilitate construction of a high performance and highly reliable disk subsystem with large storage capacity.
With respect to data formatting, it is possible to change it to a format different from the one at the time of shipment by performing reinitialization on the installed system.
C141-E078-02EN 1 - 1

1.1 Standard Features

(1) Compactness
The IDD has the FC-AL controller which supports the Arbitrated Loop (FC-AL) of the fibre chan nel modes defined by the ANSI standa rd, embedded in t he 3.5-inch fixed disk drive form fact or.
(2) FC-AL standard
The IDD provides not only FC-AL basic functions but also the following features:
Arbitration
Data frame CRC function
Command set which meets the logical specification of the SCSI CCS (Common Command
Set for Direct Access Device) requ i rement s (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 fun ct i on s.
(3) Dual port support
In order to support dual ports, the IDD is equipped with two pairs of fibre channel driver/receiver.
(4) High speed data transfer
The data transfer rate on the fibre channel loop is 106.25 MB/s maximum. In addition, the large capacity data buffer of the IDD allows the user to make full use of the high speed data transfer capability of the fibre channel loop.
(5) High speed spindle motor
The IDD increases the number of revolutions of the spindle motor from conventional 7,200 rpm to 10,025 rpm. Increasing the number of revolutions of the spindle motor will make it possible to improve the data transfer rate and reduce the rotation wait time.
(6) 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.
C141-E078-02EN1 - 2
(7) 4MB programmable multi-segment data buffer
Data is transferred between fibre-channel loop and disk media through the embedded 4MB data buffer in the IDD. This buffer can be divided into maximum 32 areas. This feature provides the suitable usage environment for users.
Since the initiator can control the disconnect/reconnect timing on the fibre-channel loop 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 fibre-channel regardless of actual data transfer rate of the disk drive.
(8) 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 .
(9) Command queuing feature
The IDD can queue maximum 63 commands, and optimizes the issuing order of queued commands by the reordering function. This feature realizes the high speed processing.
(10) 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.
(11) Enclosure service function
The IDD supports an enclosure service interface (ESI) compliant with the SFF-8067. This interface provides the function of setting/readin enclosure service information using the SCSI-3 enclosure service command set (SES).
(12) Error recovery
The IDD can try to recover from errors in fibre-channel loop 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.
(13) Automatic alternate block reassignment
If a defective data block is detected during read, the IDD can automatically reassign its alternate data block.
C141-E078-02EN 1 - 3
(14) Programmable data block length
Data can be accessed in fixed-block l ength unit s. Th e data block length is programmable, and can at initializing with a multiple of four for the 512 to 528 bytes.
(15) 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.
(16) High speed positioning
A rotary voice coil motor achieves fast positioning.
(17) Large capacity
A large capacity can be obtained from 3-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.
(18) Start/Stop of spindle motor
Using the SCSI command, the host system can start and stop the spindle motor.
(19) Diagnosis
The IDD has a diagnostic capability which checks internal controller functions and drive operations to facilitate testing and repair.
(20) 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.
(21) Low noise and low vibration
The noise level is low: Approx. 4. 2 bels for th e MAF3364FC and 4.0 bels for the MAG series. This makes it ideal for office use. The IDD has rubber vibration isolators, which minimize the transfer of vibration.
(22) Microcode downloading
The IDD implements the microcode download feature. This feature achieves easy maintain ability of the IDD and function enhancing.
C141-E078-02EN1 - 4

1.2 Hardware Structure

An outer view of the IDD is given in Figures 1.1 and 1.2. T he 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.

C141-E078-02EN 1 - 5
(1) Disks
The disks have an outer diameter of 84 mm (3.31 inch) and inner diameter of 25 mm (0.98 inch). The disks are good for at least 15,000 contact starts and stops. Each model contains following number of disks.
MAF3364:10 MAG3182:5 MAG3091:3
(2) Heads
The MR (Magnet - Resistive) of the CSS (contact start/stop) type heads are in contact with the disks when the disks are not rotating, and automatically float when the rotation is started. Figure
1.5 shows the configuration of disks and heads.

(3) Spindle motor
The disks are rotated by a direct-drive hall-less DC motor. The motor speed is controlled by a feedback circuit using the counter electromotive current to precisely maintain the speed at ±0.5% of the sp eci fied speed.
C141-E078-02EN1 - 6
(4) Actuator
The actuator, which uses a rotary voice coil motor (VCM), consumes little power and generates little heat. The head assembly at the end of the actuator arm is controlled and positioned via feedback of servo information in the data. The actuator positions heads on the CCS zone over the disk and is locked by the mechanical lock when the power is off or the spindle motor is stopped.
(5) Air circulation (recirculation filter, breather filter)
The heads, disks, and actuator are hermetically sealed inside a disk enclosure (DE) to keep out dust and other pollutants. The DE has a closed-loop air recirculation system. Using the movement of the rotating disks, air is continuously cycled through a filter. This filter will trap any dust generated inside the enclosure and keep the air inside the DE contaminant free. To prevent negative pressure in the vicinity of the spindle when the disks begin rotating, a breather filter is attached. The breather filter also equalizes the internal air pressure with the atmospheric pressure due to surrounding temperature changes.
(6) Read/write circuit
The read/write circuit uses head LSI chips and extended partial response class 4 maximum likelihood (EPR4ML) modulator and demodulator circuit to prevent errors caused by external noise, thus improving data reliability.
(7) Controller circuit
The controller circuit uses LSIs to increase the reliability and uses a high speed microprocessing unit (MPU) to increase the performance of the SCSI controller.

Figure 1.4 FC-AL syst e m confi g uration
The mode of connection of all devices to the fibre channel is called “node.” The drive and initiator correspond to the node shown in Figure 1.4. Each node has at least one port called “N­port.” In the FC-AL, a port is particularly called “node loop (NL) port.” The MAF3364FC and MAG series have two ports; one is connected to one FC-AL and a ma xim um of 126 NL ports can be connected to on e loop.
(1) Loop configuration
One port incorporates a transmit circuit and receive ci rcuit . In formation is transmitted/received by differential signals via electric signal lines. This pair of signal lines is called a link. Since signals on a link are transmitted in one direction, wiring must be conducted so that it may form a loop connection on t he system.
In the case of the FC-AL interface, information is transmitted/received via ea ch n ode conn ected on a loop. Accordingl y, if the power supply is off at a node connected to the loop or if inter face signals cannot be transmitted/received nor mally, the loop will no longer function. To avoid such a nonconformity, a circuit called “port bypass circuit” is generally provided on the back plane of the system. BC in Figur e 1 . 4 shows this por t bypass cir cui t .
(2) Node addressing
Each node on the fibre channel loop is assigned its specific model number (SEL ID). The SEL ID of the drive is set at the signal level on the back plane through 7 signals from SEL_0 to SEL_6 of the SCA interface connector (CN1). In signal bit weighting, SEL_6 is the MSB indicating 2
6
and SEL_0 is the LSB indicating 20.
The SEL ID setting of the drive ranges from #0(x‘00’) to #125(x‘7D’).

2.1.5 Reliability

(1) Mean Time Between Failures (MTBF)
MTBF of the IDD during its life time is 1,000,000 hours (operating: 24 hours/day, 7 days/week avera ge DE surface temper ature: 40 ° C or less).
Note:
The MTBF is defined as:
Operating time (hours) at all field sites
MTBF =
The number of equipment failures (*1) from all field sites
*1 Failure of the equipment means failure that requires repair, adjustments, or replacement.
Mishandling by the operator, failures due to bad en vironmen tal conditions, power trouble, host system trouble, cable failures, or other failures not caused by the equipment are not considered.
