Product Features
The Ultrastar 15K73 series uses high performance sputtered disks, GMR heads, and a
rotary type voice coil motor to drive the heads. These features provide high capacity, high
speed positioning and high reliability.
Fibre Channel (FC) type of the Ultrastar 15K73 uses a SCSI interface as the upper level
layer though the physical host interface is changed to Fibre Channel. Therefore, the host
can access the FC disk drive with almost same manner as the SCSI disk drive. Some
functions dependent on physical interface is different from that of SCSI disk drives.
FC-AL Interface specifications for the Ultrastar 15K73 are found in the companion
manual:
" Hitachi 3.5 inch Magnetic Disk Drive Reference Manual for Ultrastar 15K73
(Fibre Channel Interface Specification) ".

Note 1. Start time means that the time of becoming ready, after DC power has been
applied in the case of Enable Auto Start mode, or after Start Unit command
(immed=0) has accepted in other case. If internal retry is executed during the Startup operation, the Start time may exceed typical value. It is recommended to have 60
seconds for the Start time. In the case of a spindle start-up failure, the time of an
internal retry operation is 130 seconds maximum.
Caution
Note 2. Beginning of stop time is basically decided by +12V DC power off. In case of +5V
DC power off only, stop time is 65 seconds (typ). Do not move the drive until motor
stop completely. Stop time means that the time to stop the spindle rotation, after DC
power has been shut off, or after stop operation has started.

When multiple disk drives are connected to the same power supply and turned on
simultaneously, a large current will be required at power up.
In the above case, it is recommended to turn the motors on one by one at intervals in
order to minimize 12V line current.
This can be done according to the following 3 methods:
1. If Command Start mode is set;
(1) Use a spindle start command for each drive, issuing it to the next drive after
receiving the previous drive’s Ready condition.
or
(2) Use the spindle start command for each drive, issuing it at intervals of more than
10 seconds.
2. If Delayed Start mode is set;
Upon power on condition, the drives will automatically spin up in 10 second intervals
according to their Arbitrated Loop Physical Address (AL_PA). (The drive with the
lowest AL_PA will start first.) In the case that their AL_PA are more than 7, the drives
will automatically spin up in 10 second intervals according to the modulo 8 value of
numeric AL_PA of the drive.
3. If Auto Start mode is set;
Manually power on drives at intervals of more than 10 seconds.

6 Interface
6.1 Summary of SCSI Controller
The Ultrastar 15K73 SCSI controller interfaces between the drive and the host
computer
with the Small Computer System Interface (SCSI).
(1) ANSI standard
The controller supports the SCSI interface that conforms to the ANSI specifications
shown in chapter 2.
(2) Compact design
The controller is embedded within the disk drive.
(3) FIFO buffer
The SCSI controller has 8M bytes of FIFO buffer. This data buffering feature prevents
the SCSI controller from delay during the reconnect process and reduces the latency
time that is generated by the difference of the data transfer rate between media and
host.
(4) Automatic error retry
The controller automatically retries whenever the disk drive encounters errors.
(5) Automatic error corrections
The controller uses 40 bytes ECC and On-The-Fly to automatically correct read
errors, without latent rotational time.
Drawing No. Sheet No. Revision 4
K6602910
19/38
2003/6/6
(6) Parameter save feature
The controller saves the controller/device parameters (MODE SELECT parameters)
specified by the host onto the disk drive. The parameters are automatically
restored at power-on time.
(7) Tagged Command Queuing
A maximum of 110 commands can be enqueued to this drive. The drive does not have
to connect and disconnect to the host controller even if the SCSI command has been
issued successively, so the overhead time of the SCSI bus can be reduced.
(8) S.M.A.R.T. (Self - Monitoring, Analysis and Reporting Technology)
This function helps predict a failure related to the degradation of the disk drive itself.
For users seeking to use the drive as long as possible, S.M.A.R.T. can be used to
predict when failure might occur. The user can use this information to back-up the data
before failure.
The S.M.A.R.T. report is written on the disk at regular intervals that are not based on
drive usage.
(9) Automatic Read Reallocation
When an error is detected on reading the data, this function automatically assigns an
alternate sector in place of the defective sector and stores the data on the alternated
sector.
(10) Write Cache
The controller can return a completion of a WRITE command with a GOOD status after
receiving the data from the host but before writing the data from its buffer to the media.
The Deferred Error function reports an Disk Access Error to the host computer if an
error occurs when the data are being stored on the disk medium after the GOOD status
was already returned. In this case, any data still in the buffer (not yet written to the
media) is not assured.
(11) Log Save
Diagnostic information is written on the disk at regular intervals that are not based on
drive usage.

6.3 Summary of FC-AL
This FC Disk Drive is made based on the Hitachi Disk Drive with Parallel SCSI Interface,
and has same basic functions.
However, as the host interface is changed to Fibre Channel, functions depending on the
physical host interface is different each other.
This section describes the characteristics of the Hitachi FC Disk Drive changed to have
Fibre Channel Interface.
(1) SCSI Interface
Though the physical host interface is changed to Fibre Channel, the FC Disk Drive adopts
the SCSI interface as the upper level layer. Therefore, the host can access the FC Disk
Drive with almost same manner as the SCSI Disk Drives.
Some functions dependent on physical interface should be different from that of SCSI Disk
Drives.
(2) High-speed Data Transfer
The Fibre Channel can transfer data with 200 MB/s. The host can get sufficient throughput
even in the environment with multiple devices connected on the same Fibre Channel
interface.
(3) Number of devices connected
Based on the Fibre Channel Arbitrated Loop (FC-AL), maximum 126 devices(including
host computers) can be connected on the same Fibre Channel. Therefore, a flexible
system configurations can be available.
This FC Disk Drive supports the Arbitrated Loop (Private and Public).
(4) Dual Port Function
During the data transferring in one port, this FC Disk Drive can queue commands received
in another port.

7.4 Precautions on the off-line test or bench test
When the off-line test or bench test is performed the drive should be tightly fixed
and cooled. The set-up should be similar to the actual system configuration.
7.5 Cooling of the drive
Keep the drive (HDA and PCB) cool by using a FAN. Reliability and life of the drive
increases as the temperature is lower.
Caution
7.6 Reliability temperature
The temperature measurement points and temperature limits are shown below.
1. The maximum temperature assures the data reliability, seek error rate, and must not
be exceeded.
2. The reliability temperature maintains the MTBF of the drive and must not be
exceeded in order to ensure its reliability. MTBF is also based on a nominal voltage
condition.
3. The maximum temperature of HDA includes momentary temperature rise. Average
temperature of HDA has to be less than this temperature.

Precautions for handling
The drive is sensitive to shock, vibration, over voltage, temperature, humidity,
corrosive gas, magnetic force and electrostatic discharge.
If these forces contact the electrical or mechanical components (magnetic heads,
magnetic disks), the drive will break down, degrade, or storage data will be lost.
The following handling guidelines are mandatory.
(1) Handle the drive on the appropriate cushion (for example, anti-static pad with
thickness of 10mm or more) to prevent from shock and vibration.
(2) Handle the drive with a wrist band, an anti-static mat, or without direct touch of the
hands to the PCB in order to prevent static electricity discharge.
(3) Handle the drive in an environment (Temperature, Moisture, Corrosive gas), which
follows the drive specification and prevents unforeseen complications.
8.1 Packing
After cleaning the drive, pack it in the following manner to protect it from moisture.
(1) Put the drive in an electro-static shielding bag with desiccant.
(2) Packing materials, i.e. electro-static shielding bag, cardboard box, cushion, etc.,
should not contain corrosive gas, saline or organic-metal compound. (Example
organic silicon, organic tin)
(3) If the package has no damage after unpacking, reserve it for storage or
transportation of the drive.
But 20-unit packing material is suitable for only 20 units packing.
When less than 19 units, it is recommended to use the 5-unit packing material.
5-unit packing material covers the quantity from 1 to 5.
8.2 Transportation
(1) Pack the drive so as to maintain above-mentioned environmental conditions during
transportation. (Refer to section 3.2)
(2) When you take the drive out of the packing case and carry it on a hand truck, lay it
on cushioning material (for example, urethane foam cushioning with a thickness of
10mm or more).
8.3 Storage
When storing, pack the drive to protect it against moisture. (Refer to section 3.2)
In case that storage period becomes long, unpack, exchange a desiccant and repack.
This operation shall be executed every 3 months.

Maintenance
9.1 The HDD itself is maintenance free and there are no individual parts that require
maintenance. If maintenance for the HDD is required, the entire product will need to
be serviced, since it can not be divided into parts. System maintenance should be
executed by the host system.
9.2 The supplier will repair or exchange the product due to malfunction covered under
the warranty. The warranty and service will be agreed upon between the customer
and the supplier. The supplier is neither liable or obligated to service any product
due to carelessness or mishandling of product.
9.3 Even if the drive fault occurs during the In-warranty period, the supplier will repair or
replace the drive but will not be liable for any expenses of disk drive installation or
detachment to or from system. (This includes data back up, data copy, etc.)

11.4 Enable Port Bypass
The -EN Bypass Port 1 and -EN Bypass Port 2 signals control the port bypass circuits
(PBC) located external to the drive. The PBC allows a loop to remain functional in the event
of a drive failure or removal. When these signals are active (low), the PBC bypasses the
drive on the associated port. If the drive is not installed, a pull down resistor, 1k ohm,
located with the PBC should be used to insure the bypass is enabled.
11.5 -Parallel ESI and SEL0-6
The -Parallel ESI is an output from the drive. This signal provides the enclosure with an
indication of the present function of the SEL0-6 lines. When the -Parallel ESI is high, the
enclosure must provide address information on the SEL0-6 lines. The drive has 39k ohm
pull up resistors on the SEL0-6 lines. The backplane is required to provide high and low
inputs to the SEL0-6 lines by using proper pull up or pull down resistors (10k ohm or less).
When the -Parallel ESI is low, the enclosure switches to Enclosure Service Interface (ESI)
mode. Refer to the Fibre Channel Interface Specification Manual for Ultrastar 15K73 for a
description of ESI operation.
