    CHAPTER 1 GENERAL DESCRIPTION Standard Features Hardware Structure 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)].
  • Page 19: Standard Features

    Standard Features 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 . SCSI/CCS standard The IDD provides not only SCSI basic functions but also the following features: Arbitration Disconnection/reselection...
  • Page 20 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 may be limited by the cable length, transmission characteristics of the SCSI bus and the connected SCSI device number.
  • Page 21 (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.
  • Page 22: Hardware Structure

    (18) 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. (19) Low noise and low vibration The noise level is low; approx. 4.2 bels for MAF series and 4.0 bels for MAE and MAG series.

  • Page 25: Disk/Head Configuration

    Disks The disks have an outer diameter of 95 mm (3.74 inch) and inner diameter of 25 mm (0.98 inch) for MAE series, and 84 mm (3.3 inch) outer diameter and 25 mm (0.98 inch) inner diameter for MAF/MAG series. The disks are good for at least 15,000 contact starts and stops. Each model contains following number of disks.
  • Page 26 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 specified speed. Actuator The actuator, which uses a rotary voice coil motor (VCM), consumes little power and generates little heat.
  • Page 27: System Configuration

    System Configuration Figure 1.8 shows the system configuration. The IDDs are connected to the SCSI bus of host systems and are always operated as target. The IDDs perform input/output operation as specified by SCSI devices which operate as initiator. Figure 1.8 System configuration SCSI bus configuration Up to eight SCSI devices operating as an initiator or a target can be connected to the SCSI bus...
  • Page 28 Addressing of peripheral device Each SCSI device on the bus has its own unique address (SCSI ID:#n in Figure 1.6). For input/output operation, a peripheral device attached to the SCSI bus that operates as target is addressed in unit called as logical unit. A unique address (LUN: logical unit number) is assigned for each logical unit.

  • Page 41 User space The user space is a storage area for user data. The data format on the user space (the length of data block and the number of data blocks) can be specified with the MODE SELECT or MODE SELECT EXTENDED command. The default number of cylinders in the user space is 10,200 for MAF series, 12,000 for MAE series and 9,866 for MAG series.
  • Page 42: Alternate Spare Area

    3.1.2 Alternate spare area The alternate spare area is provided in the last track of each primary cylinder in the user space, and in the last track of the cylinder and the alternate cylinder. The spare area in each cylinder is placed at the end of the last track as shown in Figure 3.2. These spare sectors are located in the end of the track logically, not necessarily located at the end physically because of track skew or cylinder skew.
  • Page 43: Track Format

    3.1.3 Track format Physical sector allocation Figure 3.4 shows the allocation of the physical sectors in a track. The length in bytes of each physical sector and the number of sectors per track vary depending on the logical data block length.
  • Page 44: Track Skew/Cylinder Skew

    Figure 3.5 Track skew/cylinder skew The number of physical sectors (track skew factor and cylinder skew factor) corresponding to the skew time varies depending on the logical data block length because the track skew and the cylinder skew are managed for individual sectors. The IDD automatically determines appropriate values for the track skew factor and the cylinder skew factor according to the specified logical data block length.
  • Page 45: Sector Format

    3.1.4 Sector format Each sector on the track consists of an ID field, a data field, and a gap field which separates them. Figure 3.6 gives sector format examples. LC/LP models DATA BCRC Sync Servo DATA 1 DATA 2 BCRC ECC Sync Sync MC/MP models...
  • Page 46 The logical block address is written in this field, but it is not written with MP/MC models because it is appended to BCRC field information. Data field User data is stored in the data field of the sector. The length of the data field is equal to that of the logical data block which is specified with a parameter in the MODE SELECT command.
  • Page 47: Format Capacity

    3.1.5 Format capacity The size of the usable area for storing user data on the IDD (format capacity) varies according to the logical data block or the size of the spare sector area. Table 3.4 lists examples of the format capacity when the typical logical data block length and the default spare area are used. The following is the general formula to calculate the format capacity.
  • Page 48: Logical Data Block Addressing

    Logical Data Block Addressing Independently of the physical structure of the disk drive, the IDD adopts the logical data block addressing as a data access method on the disk medium. The IDD relates a logical data block address to each physical sector at formatting. Data on the disk medium is accessed in logical data block units.
  • Page 49: Defect Management

    Defect Management 3.3.1 Defect list Information of the defect location on the disk is managed by the defect list. The following are defect lists which the IDD manages. P list (Primary defect list): This list consists of defect location information available at the disk drive shipment and is recorded in a system space.
  • Page 50 The alternate block allocation is executed by the FORMAT UNIT command, the REASSIGN BLOCKS command, or the automatic alternate block allocation. Refer to OEM Manual–SCSI Logical Specifications–for details of specifications on these commands. The logical data block is allocated to the next physically continued sectors after the above sector slip treatment is made.
  • Page 51: Alternate Block Allocation By Format Unit Command

    : n represents a logical data block number : Defective sector : Unused spare sector Figure 3.7 Alternate block allocation by FORMAT UNIT command If the data block verifying operation (certification) is not permitted (DCRT flag = 0) in the FORMAT UNIT command, the IDD checks all initialized logical data blocks by reading them out after the above alternate block allocation is made to initialize (format) the disk.
  • Page 52: Alternate Block Allocation By Reassign Blocks Command

    Alternate block allocation by REASSIGN BLOCKS command When the REASSIGN BLOCKS command is specified, the alternate block is allocated to the defective logical data block specified by the initiator by means of alternate sector treatment. If there are unused spare sectors in the same cylinder as the specified defective logical data block, the alternate block is allocated to these unused spare sectors.
  • Page 53 Automatic alternate block allocation If the ARRE flag in the MODE SELECT parameter permits the automatic alternate block allocation, the IDD automatically executes the alternate block allocation and data duplication on the defective data block detected during the READ EXTENDED command. This allocation method is the same as with the REASSIGN BLOCKS command (alternate sector treatment).

    If an error is detected in initial self-diagnosis the LED blinks. In this case, it is recommended to issue the REQUEST SENSE command from the initiator (host system) to obtain information (sense data) for error analysis. IMPORTANT The LED lights during the IDD is executing a command. However, in same commands, the lighting time is only an instant.

However, it is recommended to use the default setting in normal operations. Disconnection/reconnection parameters (page code = 2) The following parameters are used to optimize the start timing of reconnection processing to transfer data on the SCSI bus at a read (READ or READ EXTENDED command) or write operation (WRITE, WRITE EXTENDED, or WRITE AND VERIFY command) of the disk.

    CHAPTER 6 DIAGNOSTICS AND MAINTENANCE Diagnostics Maintenance Information This chapter describes diagnostics and maintenance information. Diagnostics 6.1.1 Self-diagnostics The IDD has the following self-diagnostic function. This function checks the basic operations of the IDD. Initial self-diagnostics Online self-diagnostics (SEND DIAGNOSTIC command) Table 6.1 lists the contents of the tests performed with the self-diagnostics.
  • Page 107 Brief test contents of self-diagnostics are as follows. a. Hardware function test This test checks the basic operation of the controller section, and contains following test. RAM (microcode is stored) Peripheral circuits of microprocessor (MPU) Memory (RAM) Data buffer b. Seek test This test checks the positioning operation of the disk drive using several seek modes (2 points seek, 1 position sequential seek, etc.).
  • Page 108 The IDD does not reply to the SCSI bus for up to 2 seconds after the initial self-diagnostics is started. After that, the IDD can accept the I/O operation request correctly, but the received command, except the executable commands under the not ready state (such as INQUIRY, START/STOP UNIT), is terminated with the CHECK CONDITION status (NOT READY [=2]/logical unit not ready [=04-00]) during the interval from the spindle motor becomes stable to the IDD becomes ready.
  • Page 109: Test Programs

    When an error is detected in the self-diagnostics, the IDD terminates the SEND DIAGNOSTIC command with the CHECK CONDITION status. At this time only when an error is detected in the hardware function test, the LED on the front panel of the disk drive blinks.
  • Page 110: Maintenance Information

    Interface (SCSI bus) test The operations of the SCSI bus and data buffer on the IDD are checked with the WRITE BUFFER and READ BUFFER commands. Basic operation test The basic operations of the IDD are checked by executing self-diagnosis with the SEND DIAGNOSTIC command (see Subsection 6.1.1).
