  • Page 22: Performance Specification

    Data Capacity 2.3.1. The SDX-900V includes a data compression capability. When data compression is enabled the drive capacity can increase from 2 times to 3 times. The efficiency of the data compression depends on the actual data that is being compressed and cannot be predicted precisely prior to compression.

  • Page 23: Data Transfer Rate

    Burst Transfer Rate to and from the SCSI Bus 2.3.2.2. The SDX-900V will transmit and receive data bursts to and from the SCSI bus at a maximum burst rate of 12Mbyte per second, using Ultra 160 asynchronous transfers and maximum of 160Mbyte per second, using Ultra160 synchronous transfers.

  • Page 24: Error Rate

    2.3.12. Mean Time to Repair The Mean Time To Repair (MTTR) of the SDX-900V is 30 minutes. Since at the field level the entire drive is considered a Field Replaceable Unit (FRU) the time to replace the drive with a new one is less that 30 minutes.

  • Page 25: Safety

    Conditions of Acceptability 2.4.1. The SDX-900V is for use only in equipment where the suitability of the combination has been determined by an appropriate certification organization (for example, Underwriters Laboratories, Inc. or the Canadian Standards Association in North America, and the British Standards Institution or Verband Deutscher Elektrotechniker in Europe).

  • Page 26: Data Compression

    The AIT-4 Format allows both compressed and uncompressed data to reside on the same tape. The Sony SDX-900V has a DIP switch to disable the Data Compression/ Decompression. After power-on reset with this DIP switch set, both data compression and data decompression are disabled However, a MODE SELECT command can override the setting of this DIP switch.

    Power-Fail or SCSI Reset Handling 4.3.3. If there is a power-fail, the SDX-900V performs the following actions, and reverts to its default configuration: (1) The drive remains positioned at the point where the power-fail or SCSI Reset occurred. (2) It executes the Power-Up sequence of self-tests. (When power is restored.) (3) The drive returns CHECK CONDITION status for the first command after the power-fail or Reset.

  • Page 45: Scsi Interface

    5. SCSI Interface 5.1. Introduction The Sony SDX-900V uses the SCSI interface to connect to the host system. The Small Computer System Interface (SCSI) is an industry standard interface, approved by the American National Standards Institute (ANSI). It is recommended that this document be used along with the ANSI standard document. The ANSI specification defines the interface in general while this document describes the specific implementation for this unit.

  • Page 48: Message Specification

    The table below lists the Messages supported by the SDX-900V. The SDX-900V supports the Synchronous Data Transfer Request Extended Message, and the Wide Data Transfer Request Message.

  • Page 49: Command Complete (00H)

    For double transition (DT) synchronous data transfer the REQ/ACK OFFSET is the maximum number of REQ transitions allowed to be outstanding before a corresponding ACK transition is received at the target. The size of a data transfer shall be 2 bytes. SONY AIT-4 drive SDX-900V series Ver.2.1...

  • Page 50: Synchronous Data Transfer Request (01H)

    Transfer period is the minimum time allowed between leading edges of successive REQ pulses and of successive ACK pulses. The SDX-900V supports the following transfer periods: SONY AIT-4 drive SDX-900V series Ver.2.1...
  • Page 51 ACK pulse is received at the target. A REQ/ACK offset value of ZERO shall indicate asynchronous data transfer mode. The SDX-900V supports synchronous data transfer REQ/ACK offset values from 1 to 127. The originating device (the device that sends the first of the pair of SDTR messages) sets its values according to the rules above to permit it to receive data successfully.

  • Page 52: Wide Data Transfer Request

    After successfully completing the MESSAGE OUT phase, the target shall respond with the proper WDTR message. If an abnormal condition prevents the target from returning an appropriate response, both devices shall go to eight-bit data transfer mode for data transfers between the two devices. SONY AIT-4 drive SDX-900V series Ver.2.1...

  • Page 53: Save Data Pointer (02H)

    The unit will support this message as an initiator. As a target, the unit supports this message and will disconnect if allowed by the initiator.
