  • Page 25: Chapter 1 General Description

    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 type fixed disk drives with an embedded Fibre-Channel controller. The interface used to connect the MAN-series disk drives 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 26 General Description Standard Features Compactness In a compact enclosure having the 3.5-inch HDD form factor, the IDD contains an FC-AL controller, which supports the Arbitrated Loop technology (FC-AL), a Fibre Channel technology defined by the related ANSI standard. FC-AL standard The IDD provides not only FC-AL basic functions but also the following features: Arbitration Disconnection/Reconnection...

  • Page 27: 1.1 Standard Features

    1.1 Standard Features Programmable multi-segment data buffer The data buffer is 8M bytes. Data is transferred between Fibre Channel Loop and disk media through this data buffer. 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 Loop regardless of actual data transfer rate of the disk drive.
  • Page 28 General Description (12) Automatic alternate block reassignment If a defective data block is detected during read or write the IDD can automatically reassign its alternate data block. (13) Programmable data block length Data can be accessed in fixed-block length units. The data block length is programmable, and can be specified at initializing with a multiple of four within the range of 512 to 528 bytes.

    1.2 Hardware Structure Hardware Structure An outer view of the IDD is given in Figures 1.1. The IDD is composed of the disk, head, spindle motor, mounted 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.

  • Page 31: 1.3 System Configuration

    1.3 System Configuration Read/write circuit The read/write circuit utilizes a read channel mounted with a head IC that supports high-speed transmission and an MEEPR4ML (Modified Enhanced Extended Partial Response Class 4 Maximum Likelihood) modulation/demodulation circuit in order to prevent errors being triggered by external noise and to improve data reliability.
  • Page 32 General Description Loop configuration A port embedded with sending and receiving circuits uses differential signals to send and receive data on electric signal lines. A pair of signal lines is called a link. Since signals are sent in one direction on a link, the links in a system must be connected to form a loop.

Alternate cylinders will be used for alternate blocks when primary cylinders in the user space are used up.

  • Page 51: 3.3 Defect Management

    3.3 Defect Management When the logical data block is allocated, some sectors (track skew and cylinder skew) shown in Figure 3.5 are provided to avoid waiting for one turn involving head and cylinder switching at the location where the track or the cylinder is physically switched. See Subsection 3.3.2 for defective/alternate block treatment and the logical data block allocation method in case of defective sectors exist on the disk.
  • Page 52 Data Format Both of the following are applicable to the alternate block allocation. Sector slip treatment: Defective sectors are skipped and the logical data block corresponding to those sectors is allocated to the next physical sectors. This treatment is made on the same cylinder as the defective sector's and is effective until all spare sectors in that cylinder are used 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.

    3.3 Defect Management : 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 54: Figure 3.8 Alternate Block Allocation By Reassign Blocks Command

    Data Format 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 55 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 IDD automatically executes the alternate block allocation and data duplication on the defective data block detected during the READ or READ EXTENDED command.

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.

    Replacement is usually done by the user, retail dealer, distributor, or OEM engineer. Factory maintenance (parts replacement) This replacement can only be done by Fujitsu. Replacement includes maintenance training and OEM engineer support. OEM engineers usually support retail dealers and distributors.

  • Page 91: Revision Numbers

    6.2 Maintenance Information 6.2.4 Revision numbers The revision number of the disk drive is represented with a letter and a number indicated on the revision label attached to the DE. Figure 6.1 shows the revision label format. Figure 6.1 Revision label (example) Indicating revision number at factory shipment When the disk drive is shipped from the factory, the revision number is indicated by deleting numbers in the corresponding letter line up to the corresponding number with = (see Figure 6.2).

  • Page 92: Tools And Test Equipment

    IMPORTANT When the revision number is changed after the drive is shipped from the factory, Fujitsu issues "Engineering Change Request/Notice" in which the new revision number is indicated. When the user changes the revision number, the user should update the revision label as described in item (2) after applying the modification.

    Diagnostics and Maintenance Operation Check 6.3.1 Initial seek operation check If an error is detected during initialization by the initial seek operation check routine at power-on, the IDD sends the Fault LED Out signal to the interface connector. The spindle motor of the disk drive then stops, and the disk drive is unusable.
