  • Page 19: Chapter 1 General Description

    CHAPTER 1 General Description Standard Features Hardware Structure System Configuration This chapter describes the feature and configuration of the MBA3xxxFD. The HDDs are high performance large capacity 3.5-inch hard disk drives with an embedded Fibre-Channel controller. The interface used to connect the HDDs to the host system complies with NCITS TR-19 Fibre Channel Private Loop SCSI Direct Attach (FC-PLDA), which is the Fibre Channel PLDA standard covering items ranging from Fibre Channel physical layers to SCSI command protocols.
  • Page 20 General Description High-speed data transfer The maximum data-transfer speed on the Fibre Channel loop is 425.0 MB/s. The large-capacity data buffer of the HDDs enable the effective use of such high-speed data transfers available on the Fibre Channel loop. Continuous block processing The addressing method of data blocks is logical block address.
  • Page 21 1.1 Standard Features (11) Enclosure service function The HDDs support the enclosure service interface (ESI), which complies with SFF-8067. The ESI interface enables use of the SCSI-3 enclosure service command set (SES) so that the functions that specify and read enclosure service information can be used. (12) Error recovery The HDDs can try to recover from errors in the HDD using its powerful retry processing.
  • Page 22 General Description (18) Start/Stop of spindle motor Using the SCSI command, the host system can start and stop the spindle motor. (19) Diagnosis The HDDs have a diagnostic capability which checks internal controller functions and HDD operations. Also, for early detection of and recovery from the errors on the disk, the HDD has a function for periodically implementing a full scan of the disk.

  • Page 23: 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).

    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 35 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 36: 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.

    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.

    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.
