CHAPTER 1 GENERAL DESCRIPTION 1.1 Standard Features 1.2 Hardware Structure 1.3 System Configuration This chapter describes the feature and configuration of the intelligent disk drives (IDD). IDDs are high performance large capacity 3.5-inch fixed disk drives with an embedded SCSI controller. The interface between the IDD and host system is based on SCSI (Small Computer System Interface) standard [ANSI X3.131 - 1986: Small Computer System Interface (SCSI), ANSI X3.
1.1 Standard Features (1) Compactness Since the SCSI controller circuit is embedded in the standard 3.5-inch fixed disk drive form factor, the IDD is extremely compact. The IDD can be connected directly to the SCSI bus of the host system .
Note: The maximum data transfer rate in asynchronous mode may be limited by the response time of initiator and the length of SCSI bus length. The maximum data transfer rate in synchronous mode may be limited by the cable length, transmission characteristics of the SCSI bus and the connected SCSI device number. (5) Continuous block processing The addressing method of data blocks is logical block address.
(10) Error recovery The IDD can try to recover from errors in SCSI bus or the disk drive using its powerful retry processing. If a recoverable data check occurs, error-free data can be transferred to the initiator after being corrected in the data buffer. The initiator software is released from the complicated error recover processing by these error recovery functions of the IDD.
(18) Low power consumption By using highly integrated LSI components, the power consumption of the IDD is very low, and this enables the unit to be used in wide range of environmental conditions. (19) Low noise and low vibration The noise level is low; approx. 4.2 bels for MAF series and 4.0 bels for MAE and MAG series. This makes it ideal for office use. The IDD has rubber vibration isolators, which minimize the transfer of vibration.
Figure 1.2 Figure 1.
Figure 1.4 MAE series LP outer view Figure 1.5 MAG series LC/MC outer view Figure 1.
(1) Disks The disks have an outer diameter of 95 mm (3.74 inch) and inner diameter of 25 mm (0.98 inch) for MAE series, and 84 mm (3.3 inch) outer diameter and 25 mm (0.98 inch) inner diameter for MAF/MAG series. The disks are good for at least 15,000 contact starts and stops. Each model contains following number of disks.
(3) Spindle motor The disks are rotated by a direct-drive hall-less DC motor. The motor speed is controlled by a feedback circuit using the counter electromotive current to precisely maintain the speed at ±0.5% of the specified speed. (4) Actuator The actuator, which uses a rotary voice coil motor (VCM), consumes little power and generates little heat. The head assembly at the end of the actuator arm is controlled and positioned via feedback of servo information in the data.
1.3 System Configuration Figure 1.8 shows the system configuration. The IDDs are connected to the SCSI bus of host systems and are always operated as target. The IDDs perform input/output operation as specified by SCSI devices which operate as initiator. Figure 1.
(2) Addressing of peripheral device Each SCSI device on the bus has its own unique address (SCSI ID:#n in Figure 1.6). For input/output operation, a peripheral device attached to the SCSI bus that operates as target is addressed in unit called as logical unit. A unique address (LUN: logical unit number) is assigned for each logical unit. The initiator selects one SCSI device by specifying that SCSI ID, then specifies the LUN to select the peripheral device for input/output operation.

CHAPTER 2 SPECIFICATIONS 2.1 Hardware Specifications 2.2 SCSI Function Specifications This chapter describes specifications of the IDD and the functional specifications of the SCSI. 2.1 Hardware Specifications 2.1.1 Model name and part number Each model has a different data format and front panel type when shipped. (See Appendix D for the model name (type) and product number.) The data format can be changed by reinitializing with the user's system.
2.1.2 Function specifications Table 2.1 shows the function specifications of the IDD. Table 2.1 Function specifications Specification Item MAE3182 series MAE3091 series MAF3364 series MAG3182 series Formatted capacity/device (*1) 18.2 GB 9.1 GB 36.4 GB 18.2 GB 9.1 GB Unformatted capacity/device 23.1 GB 11.5 GB 45.6 GB 23.0 GB 11.
(*1) The formatted capacity can be changed by changing the logical block length and using spare sector space. See Chapter 3 for the further information. (*2) The number of user cylinders indicates the max., and includes the alternate cylinder. The number of user cylinders and alternate cylinders can be specified at format of the IDD.
2.1.3 Environmental specifications Table 2.2 lists environmental and power requirements. Table 2.
2.1.4 Error rate Errors detected during initialization and replaced by alternate block assignments are not included in the error rate. Data blocks to be accessed should be distributed over the disk medium equally. (1) Unrecoverable error rate Errors which cannot be recovered within 63 retries and ECC correction should not exceed 10 per 1015 bits. (2) Positioning error rate Positioning errors which can be recovered by one retry should be 10 or less per 108 seeks. 2.1.
(3) Service life The service life under suitable conditions and treatment is as follows. The service life is depending on the environment temperature. Therefore, the user must design the system cabinet so that the average DE surface temperature is as possible as low. • • • • • DE surface temperature: DE surface temperature: DE surface temperature: DE surface temperature: DE surface temperature: 40°C or less 45°C or less 46°C to 50°C 51°C to 55°C 56°C and more 5 years 4.5 years 4 years 3.

CHAPTER 3 DATA FORMAT 3.1 Data Space 3.2 Logical Data Block Addressing 3.3 Defect Management This chapter explains data space definition, logical data block addressing, and defect management on the IDD. 3.1 Data Space The IDD manages the entire data storage area divided into the following three data spaces.
Cylinder –37 to ~ Cylinder –30 Internal test cylinder ~ ~ Internal test space ~ SA22 Cylinder –26 to ~ Cylinder –4 • SA0 ~ ~ System space ~ Cylinder 0 Primary Cylinder 0 to Primary Cylinder (m–1) Cylinder 1 • ~• • ~ • m+n–1 User space (+ Cylinder Slip n) m+n m+n+1 Spare sector for each cylinder 10,200 / 9,866 / 12,000 (MAF) (MAG) (MAE) * Spare sectors on the last track in each cylinder are not necessarily placed at the end of the track because of a track skew or a cylinder skew.
Table 3.
(1) 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. The default number of cylinders in the user space is 10,200 for MAF series, 12,000 for MAE series and 9,866 for MAG series.
3.1.2 Alternate spare area The alternate spare area is provided in the last track of each primary cylinder in the user space, and in the last track of the cylinder and the alternate cylinder. 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.
3.1.3 Track format (1) 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. The interval of the sector pulse (length of the physical sector) is decided by multiple of 20MHz free running frequency.
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.
3.1.4 Sector format Each sector on the track consists of an ID field, a data field, and a gap field which separates them. Figure 3.6 gives sector format examples.
(4) LBA The logical block address is written in this field, but it is not written with MP/MC models because it is appended to BCRC field information. (5) Data field User data is stored in the data field of the sector. The length of the data field is equal to that of the logical data block which is specified with a parameter in the MODE SELECT command. Any even number between 512 and 528 bytes can be specified as the length. (6) BCRC It is a 2-byte error detection code. Errors in the ID field.
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 3.4 lists examples of the format capacity when the typical logical data block length and the default spare area are used. The following is the general formula to calculate the format capacity.
3.2 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. The INIT specifies the data to be accessed using the logical data block address of that data.
3.3 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. The defects in this list are permanent, so the INIT must execute the alternate block allocation using this list when initializing the disk.
The alternate block allocation is executed by the FORMAT UNIT command, the REASSIGN BLOCKS command, or the automatic alternate block allocation. Refer to OEM Manual–SCSI Logical Specifications–for details of specifications on these commands. The logical data block is allocated to the next physically continued sectors after the above sector slip treatment is made. On the other hand, the logical data block is allocated to spare sectors which are not physically consecutive to the adjacent logical data blocks.
: 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.
(2) 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.
(3) 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). IMPORTANT Automatic alternate block allocation is made only once during the execution of one command.

(3) Environmental temperature Temperature condition at installed in a cabinet is indicated with ambient temperature measured 3 cm from the disk drive. At designing the system cabinet, consider following points. • Make a suitable air flow so that the DE surface temperature does not exceed 55°C. CAUTION Heat An air flow with an adequate wind velocity must be maintained to deal with much heat generated from the MAF3364xx. Reference value: An air flow with a wind velocity of more than 0.

4.2 Power Supply Requirements (1) Allowable input voltage and current The power supply input voltage measured at the power supply connector pin of the IDD (receiving end) must satisfy the requirement given in Subsection 2.1.3. (For other requirements, see Items (4) and (5) below.) (2) Current waveform (reference) Figure 4.13 shows the waveform of +12 VDC. MAE series MAF series MAG series Figure 4.
Figure 4.14 Power on/off sequence (1) c) In a system which does not use the terminating resistor power supply signal (TERMPWR) on the SCSI bus, the requirements for +5 VDC given in Figure 4.15 must be satisfied between the IDD and the SCSI device with the terminating resistor circuit. SCSI devices with the terminating resistor Figure 4.
(4) Sequential starting of spindle motors After power is turned on to the IDD, a large amount of current flows in the +12 VDC line when the spindle motor rotation starts. Therefore, if more than one IDD is used, the spindle motors should be started sequentially using one of the following procedures to prevent overload of the power supply unit. For how to set a spindle motor start control mode, see Subsection 5.3.2. a) Issue START/STOP commands at more than 12-second intervals to start the spindle motors.

Format parameter (page code = 3) Specify the number of spare sectors for each cylinder in the "alternate sectors/zone" field and specify the number of tracks for alternate cylinders (= number of alternate cylinders × number of disk drive heads) in the "alternate tracks/zone" field. It is recommended not to specify values smaller than the IDD default value in this field. c.
5.6.4 Setting parameters The user can specify the optimal operation mode for the user system environments by setting the following parameters with the MODE SELECT or MODE SELECT EXTENDED command: • • • • Error recovery parameter Disconnection/reconnection parameter Caching parameter Control mode parameter With the MODE SELECT or MODE SELECT EXTENDED command, specify 1 for the "SP" bit on CDB to save the specified parameter value on the disk.
5. (1) The saved value of the MODE SELECT parameter is assumed as the initial value of each parameter after the power-on, the RESET condition, or the BUS DEVICE RESET message. The INIT can change the parameter value temporary (actively) at any timing by issuing the MODE SELECT or MODE SELECT EXTENDED command with specifying "0" to the SP bit in the CDB. Error recovery parameter The following parameters are used to control operations such as IDD internal error recovery: a.
Notes: 1. The user can arbitrarily specify the following parameters according to the system requirements: • • • 2. (2) ARRE TB PER The user also can arbitrarily specify parameters other than the above. However, it is recommended to use the default setting in normal operations.
(3) Caching parameters The following parameters are used to optimize IDD Read-Ahead caching operations under the system environments. Refer to Chapter 2 of SCSI Logical Interface Specifications for further details. a.
a. Control mode parameters Parameter • Queue algorithm modifier 5.7 • QErr: Resume or abort remaining suspended commands after sense pending state • DQue: Disabling tagged command queuing Default value 0 (Ordering is executed by read command only.
CHAPTER 6 DIAGNOSTICS AND MAINTENANCE 6.1 Diagnostics 6.2 Maintenance Information This chapter describes diagnostics and maintenance information. 6.1 Diagnostics 6.1.1 Self-diagnostics The IDD has the following self-diagnostic function. This function checks the basic operations of the IDD. • • Initial self-diagnostics Online self-diagnostics (SEND DIAGNOSTIC command) Table 6.1 lists the contents of the tests performed with the self-diagnostics.
Brief test contents of self-diagnostics are as follows. a. Hardware function test This test checks the basic operation of the controller section, and contains following test. • • • • RAM (microcode is stored) Peripheral circuits of microprocessor (MPU) Memory (RAM) Data buffer b. Seek test This test checks the positioning operation of the disk drive using several seek modes (2 points seek, 1 position sequential seek, etc.).
The IDD does not reply to the SCSI bus for up to 2 seconds after the initial self-diagnostics is started. 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.
When an error is detected in the self-diagnostics, the IDD terminates the SEND DIAGNOSTIC command with the CHECK CONDITION status. At this time only when an error is detected in the hardware function test, the LED on the front panel of the disk drive blinks. The INIT should issue the REQUEST SENSE command when the CHECK CONDITION status is posted. The sense data collected by the REQUEST SENSE command indicates the detail information of the error detected in the self-diagnostics.
(1) Interface (SCSI bus) test The operations of the SCSI bus and data buffer on the IDD are checked with the WRITE BUFFER and READ BUFFER commands. (2) Basic operation test The basic operations of the IDD are checked by executing self-diagnosis with the SEND DIAGNOSTIC command (see Subsection 6.1.1). (3) Random/sequential read test The positioning (seek) operation and read operation are tested in random access and sequential access modes with the READ, READ EXTENDED, or VERIFY command.
Note: The "average DE surface temperature" means the average temperature at the DE surface throughout the year when the IDD is operating. (3) Parts that can be replaced in the field The PCA cannot be replaced in the field. The DE cannot be replaced in the field. (4) Service system and repairs Fujitsu has the service system and repair facility for the disk drive. Contact Fujitsu representative to submit information for replacing or repairing the disk drive.
See Section 5.1 for notes on packing and handling when returning the disk drive. 6.2.2 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. Machine revision Figure 6.
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. At shipment Rev. A2 Revising at field Rev. A3 Figure 6.
