    CHAPTER 1 GENERAL DESCRIPTION Standard Features Hardware Structure System Configuration This chapter describes the feature and configuration of the intelligent disk drives (IDD). MAF3364FC and MAG series intelligent disk drives (IDDs) are high performance large capacity 3.5-inch fixed disk drives with an embedded fibre-channel controller. The interface between the MAF3364FC/MAG series intelligent disk drives and host system conforms to the fibre channel PLDA standard [NCITS TR-19 FIBRE CHANNEL PRIVATE LOOP SCSI DIRECT ATTACH (FC-PLDA] which covers from the fibre channel physical layer to SCSI command protocol.

  • Page 19: Standard Features

    Standard Features Compactness The IDD has the FC-AL controller which supports the Arbitrated Loop (FC-AL) of the fibre channel modes defined by the ANSI standard, embedded in the 3.5-inch fixed disk drive form factor. FC-AL standard The IDD provides not only FC-AL basic functions but also the following features: •...
  • Page 20 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...
  • Page 21 (14) 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 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.

  • Page 35: Alternate Spare Area

    The default number of cylinders in the user space is 10,200 for MAF3364FC and 9,866 for MAG series. The user, however, can select the number of cylinders to be allocated in the user space by specifying 10,200 for MAF3364FC and 9,866 for MAG series as the maximum and the number of alternate cylinders + 1 as the minimum.

  • Page 36: Track Format

    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. (Details are explained on Subsection 3.1.3.) Size can be specified by the MODE SELECT or MODE SELECT EXTENDED command.

  • Page 37: Track Format

    The interval of the sector pulse (length of the physical sector) is decided by multiple of 20MHz free running frequency. This clock is not equal to the interval of the byte clock for each zone. Therefore, the physical sector length cannot be described with a byte length. 119,700 CLKs (20MHz) Figure 3.4...

  • Page 38: Sector Format

    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 39 Each sector on the track consists of the following fields: Gaps (G1) The gap length at the time of formatting (initializing) is listed in Figure 3.7. Pattern X'00' is written on the gap field. PLO Sync In this field, pattern X'00' in the length in bytes listed in Figure 3.6 is written. Trailing (TRNG)/Sync Byte (SB) In this field, special pattern in the length in bytes listed in Figure 3.6 is written.

  • Page 40: 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 3.3 lists examples of the format capacity when the typical logical data block length and the default spare area are used.

  • Page 41: 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 42: 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 43 • Alternate sector treatment: The logical data block corresponding to defective sectors is allocated to unused spare sectors in the same cylinder or unused spare sectors in the alternate cylinder. The alternate block allocation is executed by the FORMAT UNIT command, the REASSIGN BLOCKS command, or the automatic alternate block allocation.

  • Page 44: 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 45: 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 46 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).
