This setting is used to output IOCHRDY to pin 27 of the host interface. SW2 ECC bytes -------------- 6 ON 4 bytes x 6 OFF 7 bytes In 4Byte ECC mode, the READ LONG/WRITE LONG command can be executed successfully only under the following conditions: -> READ LONG -> WRITE LONG sequence is only acceptable -> The sector number of READ LONG and WRITE LONG must be the same -> The number of sector on WRTIE LONG must be the same one that host issued to the drive on READ LONG. ********************************************************************** I N S T A L L ********************************************************************** FUJITSU M2612ET/M2613ET/M2614ET OEM MANUAL 41FH5059E-01 Notes on installation ===================== Installation direction ---------------------- horizontally vertically +---------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +--+---------------+---+ | | | | | | +----------------------+ | | | | | | | | | | | | X X | | | | | | +------X-------X-------+ | | | | | | +--+-----X---X-----+---+ | +-----+ +-----+ | | X X | +--+ +--+ | X X | +--X--------X---+ X X If the drive is installed in any of the above three installation directions, the level deviation must not exceed 5*. Never install PCA to the top! Ambient temperature ------------------- The operating temperature range for the IDD in a cabinet is specified at a distance of 3cm from the IDD. Design the air flow in the cabinet to keep. The maximum ambient temperature with in 45*C. The air circulation in the cabinet must be designed so that the PCA side of the IDD is particularly cooled. The cooling effect should be confirmed in measuring the surface temperature of the specific IC and DE. Cable requirements ------------------ The cable of twisted pairs and neighboring line separated individu- ally is not allowed to use for the host interface cable. It is be- cause that the location of signal lines in these cables is not fixed and so the problem on the crosstalk among signal lines may occur. Cable length: 0.5m Max. ********************************************************************** F E A T U R E S ********************************************************************** FUJITSU M2612ET/M2613ET/M2614ET OEM MANUAL 41FH5059E-01 Buffer ------ The M261xET supports a look-ahead cache to increase system throughput The M261xET uses 56KB of the cache to read and 6KB to write and a 2KB area to download sequencer programs. Data transfer rate ------------------ A maximum transfer rate of 7.4MB/s is accomplished with a 30MHz clock signal and high-speed buffer management. When the data transfer rate becomes near 7.4MB/s or more, the host must recieve IOCHRDY signal and maintain the transfer synchronisation by setting a wait state. Power save mode --------------- When the M261xET will not be operated for a long time, power consump- tion can be reduced by using the power save mode. The M261xET supports 2 power modes which are selectable by the POWER command: idle mode and power save mode. In the power save mode, power is supplied only to the controller circuit, the spindle motor circuit and the drive control IC. Power to the other components is shut off by the power FET. Thus low power consumption is accomplished. In this mode, the spindle keeps rotation for hot restart. Start and stop time ------------------- Typical start time (time from when power is turned on until the IDD is ready) is 8 seconds or less, and typical stop time (time to com- pletely stop when power is turned off) is 17 seconds or less. Power on/off sequence --------------------- The +5V and +12V power supplies are monitored by the voltage check circuit. The circuit allows a write current to flow only when the both voltages are normal. Accordingly, no power sequence is required. This is for protection of the content of the medium. Power consumption ----------------- Steady state 6.4W Power save state 3.5W Steady state includes SEEK, WRITE and READ operation Mean Time Between Failures (MTBF) --------------------------------- The MTBF is defined as follows: Operating time MTBF = ----------------------------------------- Number of equipment failures in the field Operating time is the total time duration during which the power is on, excluding preventive maintenance. Failure of the equipment means a failure that requires repair, ad- justment, or replacement, excluding preventive maintenance. Errors by the operator, failures due to power failures, controller faults, cable faults, bad environmental conditions, or other failures not caused by the equipment itself are not included. The IDD is designed for an MTBF of 50.000 hours. Mean Time To Repair (MTTR) -------------------------- MTTR is the average time taken by a well-trained service engineer to diagnose and repair a unit malfunction. The IDD is designed for a MTTR of 30 minutes or less. Service life ------------ Overhaul of the drive is not required for the first five years. Data protection against power failure ------------------------------------- Integrity of the data on the disk is guaranteed against all forms of abnormal DC power except a power failure during writing. Media Defect ------------ When a physical track contains two ore more bad sectors, all sectors in the track are given BAD flags in formatting before the M261xT is shipped. As regards media defect, it defines with number of bad tracks as follows. (provided that CYL0, HD0 is defect free) Number of bad tracks per drive: max. 24 M2612ET max. 36 M2613ET max. 48 M2614ET System configuration -------------------- Up to two IDDs are connectable. In principle, perfect operation cannot be guaranteed in case of daisy-chained combination (2-drvie system) of M261xET drive and other manufacturer's drive. Drive BIOS specification ------------------------ As BIOS has limitation of number of cylinders ( 1024), a host cannot be operated by physical parameters. Therefore, logical/physical translation (emulation) is needed, a host has to use M261xET by logi- cal parameters. BIOS specifications are defined by SET PARAMETERS command which a host issues. A customer who can modify FIXED DISK PARAMETER TABLE in the BIOS selects parameter freely and can set BIOS specification. However, the parameter must be selected within the storage capacity which M261xET has. And it is possible that customer uses M261xET by selecting appropriate DRIVE TYPE in the BIOS. In this case, M261xET works in the storage capacity which customer selected. Logical parameter which can use without loss of physical capacity of M261xET is shown below: M2612ET M2613ET M2614ET --------------------+-------+-------+------- Number of Cylinders | 667 | 667 | 667 --------------------+-------+-------+------- Number of heads | 8 | 12 | 16 --------------------+-------+-------+------- Sectors per track | 33 | 33 | 33 Since LOW LEVEL FORMAT is performed with these parameters, whole data area of M261xET can be formatted. M261xET is formatted with physical parameters at factory shipment. When M261xET is operated by TEST PROGRAM (Bench Mark Test etc.) which is for measurement of the performance of HDD, according to BIOS spe- cifications, actual performance may not be measured. However, the result of Bench Mark Test etc. and the performance of the actual use are not always equal. BIOS specification needs to decide that result of file access depending on systems is evaluated synthetic. ********************************************************************** G E N E R A L ********************************************************************** FUJITSU => GDT Tips & Hints about ICP controllers and other peripherals ======================================================== Tagged queues and Fujitsu M 26xx harddisks ------------------------------------------ Fujitsu Harddisks of the M26XX series do not support the SCSI-II feature tagged queues. You should disable this feature in the initialize disks menue of the GDTSetup program. An inquiry command shows, that the harddisk supports tagged queues (this is why you can enable it in the GDTSetup) but this is not true as stated by Fujitsu Germany.
