  • Page 17: Chapter 1 General Description

    CHAPTER 1 General Description Standard Features Hardware Structure System Configuration This chapter describes the feature and configuration of the MBA3xxxRC. The HDDs are high performance large capacity 3.5-inch hard disk drives with an embedded Serial Attached SCSI (SAS) controller. The interface used to connect the HDDs to the host system complies with ANSI T10/1601-D Serial Attached SCSI-1.1 (SAS-1.1), which covers items ranging from SAS physical layers to SCSI command protocols.
  • Page 18 General Description Dual SAS port support The HDDs have two pairs of driver and receiver set (PHY) for the SAS to support dual SAS port connection. On the HDDs, Primary and Secondary Ports on SAS plug connector (2 physical links plus power connections) are used for SAS port connection.
  • Page 19 1.1 Standard Features Command queuing feature The HDDs can queue maximum 128 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 HDDs can be accessed exclusively in the multi-host or multi-initiator environment by using the reserve and release functions.
  • Page 20 General Description (16) Large capacity A large capacity can be obtained from the HDDs 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. (17) Start/Stop of spindle motor Using the SAS primitive or the SCSI command, the host system can start and stop the spindle motor.

  • Page 21: 1.2 Hardware Structure

    1.2 Hardware Structure Hardware Structure The HDDs have a disk enclosure (DE) and a printed circuit board assembly (PCBA). The DE includes heads on an actuator and disks on a spindle motor mounted on the DE. The PCBA includes a read/write circuit and a controller circuit. Disks The disks have an outer diameter of 70 mm (2.8 inch).

    CHAPTER 3 Data Format Data Space Logical Data Block Addressing Defect Management This chapter explains data space definition, logical data block addressing, and defect management on the HDDs. Data Space The HDDs manage the entire data storage area divided into the following three data spaces. User space: Storage area for user data Internal test space: Reserved area for diagnostic purposes System space: Area for exclusive use of HDDs themselves...

  • Page 32: Figure 3.1 Cylinder Configuration

    Data Format Note: Spare sectors on the last track in each cell are not necessarily placed at the end of the track because of a track skew or a cylinder skew. (Details are explained in Subsection 3.1.3) Figure 3.1 Cylinder configuration Apart from the above logical configuration, the HDDs intend to increase the storage capacity by dividing all cylinders into several zones and changing a recording density of each zone.
  • Page 33 3.1 Data Space 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.

  • Page 34: Alternate Spare Area

    Data Format 3.1.2 Alternate spare area The alternate spare area consists of the last track of each cell in the user space and an alternate cylinder allocated to the last 10 cylinders of the last zone in the user space. The spare area in each cell is placed at the end of the last track as shown in Figure 3.2.

  • Page 35: Track Format

    3.1 Data Space 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. The unused area (G4) exists at the end of the track in formats with most logical data block lengths.

  • Page 36: Sector Format

    Data Format Track skew Head Track skew Head skew Head Leading logical sector in head p+1 Figure 3.5 Track skew/head skew The number of physical sectors (track skew factor and head skew factor) corresponding to the skew time varies depending on the logical data block length because the track skew and the head skew are managed for individual sectors.
  • Page 37 3.1 Data Space Each sector on the track consists of the following fields: Gaps (G1, G2, G3) No pattern is written on the gap field. PLO Sync In this field, pattern X'00' is written. Sync Mark (SM1, SM2) In this field, special pattern is written. This special pattern indicates the beginning of the data field. Data field (DATA1-DATA4) User data is stored in the data field of the sector.

  • Page 38: Format Capacity

    Data Format 3.1.5 Format capacity The size of the usable area for storing user data on the HDDs (format capacity) varies according to the logical data block or the size of the spare sector area. Table 3.1 lists examples of the format capacity when the typical logical data block length and the default spare area are used.
  • Page 39 3.2 Logical Data Block Addressing Block address of user space The logical data block address number is consecutively assigned to all of the data blocks in the user space starting with 0 to the first data block. The HDDs treat sector 0, track 0, cylinder 0 as the first logical data block. The data block is allocated in ascending order of addresses in the following sequence (refer to Figure 3.5): 1) Logical data blocks are assigned in ascending order of sector number in the same track.

  • Page 40: Defect Management

    Data Format 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 HDDs manage. P list (Primary defect list): This list consists of defect location information available at the HDD shipment and is recorded in a system space.

    3.3 Defect Management Alternate block allocation during FORMAT UNIT command execution When the FORMAT UNIT command is specified, the allocation of the alternate block to those defective sectors included in the defect list (P, G, or D) is continued until all spare sectors in the same cell are used up.

  • Page 42: Command

    Data Format Certification is permitted when DCRT flag is cleared (DCRT flag=0) in FORMAT UNIT command. The HDDs check all initialized logical data blocks by reading them out after the above alternate block allocation is made to initialize (format) the disk. 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.
  • Page 43 3.3 Defect Management Automatic alternate block allocation Automatic alternate block allocation at read operation If the ARRE flag in the MODE SELECT parameter permits the automatic alternate block allocation, the HDDs automatically execute the alternate block allocation and data duplication on the defective data block detected during the READ or READ EXTENDED command.
