3 Fixed disk subsystem description

Control Electronics

The drive is electronically controlled by a microprocessor, several logic modules, digital/analog modules, and various drivers and receivers. The control electronics performs the following major functions:

 Controls and interprets all interface signals between the host controller and the drive.  Controls read write accessing of the disk media, including defect management and error recovery.  Controls starting, stopping, and monitoring of the spindle.  Conducts a power-up sequence and calibrates the servo.  Analyzes servo signals to provide closed loop control. These include position error signal and estimated

velocity.

 Monitors the actuator position and determines the target track for a seek operation.  Controls the voice coil motor driver to align the actuator in a desired position.  Constantly monitors error conditions of the servo and takes corresponding action if an error occurs.  Monitors various timers such as head settle and servo failure.  Performs self-checkout (diagnostics).

Head disk assembly

The head disk assembly (HDA) is assembled in a clean room environment and contains the disks and actuator assembly. Air is constantly circulated and filtered when the drive is operational. Venting of the HDA is accomplished via a breather filter.

The spindle is driven directly by an in-hub, brushless, sensorless DC drive motor. Dynamic braking is used to quickly stop the spindle.

Actuator

The read/write heads are mounted in the actuator. The actuator is a swing-arm assembly driven by a voice coil motor. A closed-loop positioning servo controls the movement of the actuator. An embedded servo pattern supplies feedback to the positioning servo to keep the read/write heads centered over the desired track.

The actuator assembly is balanced to allow vertical or horizontal mounting without adjustment. When the drive is powered off, the actuator automatically moves the head to the actuator ramp outside of the disk

where it parks.

Default logical drive parameters

The default of the logical drive parameters in Identify Device data is as shown below.

Table 2 Formatted capacity

Notes:

Logical layout: Logical layout is an imaginary drive parameter (that is, the number of heads) which is used to access the drive from the system interface. The Logical layout to Physical layout (that is, the actual Head and Sectors) translation is done automatically in the drive. The default setting can be obtained by issuing an IDENTIFY DEVICE command

Drive Format

Upon shipment from HGST Japan manufacturing the drive satisfies the sector continuity in the physical format by means of the defect flagging strategy described in Section 5 on 26 in order to provide the maximum performance to users.

Cylinder allocation

Physical cylinder is calculated from the starting data track of 0. It is not relevant to logical CHS. Depending on the capacity some of the inner zone cylinders are not allocated.

Data cylinder This cylinder contains the user data which can be sent and retrieved via read/write commands and a spare area for reassigned data.

Spare cylinder The spare cylinder is used by HGST Japan manufacturing and includes data sent from a defect location.

Drive performance is characterized by the following parameters:

 Command overhead  Mechanical positioning

- Seek time

- Latency

 Data transfer speed  Buffering operation (Look ahead/Write cache)

All the above parameters contribute to drive performance. There are other parameters that contribute to the performance of the actual system. This specification defines the characteristics of the drive, not the characteristics of the system throughput which depends on the system and the application.

Mechanical positioning

Average seek time (without command overhead, including settling)

Table 5 Average seek time

The terms “Typical” and “Max” are used throughout this specification with the following meanings:

Typical. The average of the drive population tested at nominal environmental and voltage conditions. Max. The maximum value measured on any one drive over the full range of the environmental and voltage

conditions. (See Section 6.2, “Environment” and Section 6.3, “DC Power Requirements”)

Single track seek time (without command overhead, including

settling)

Common to all models and all seek modes

defect defect

skip

Media defects are remapped to the next available sector during the Format Process in manufacturing. The mapping from LBA to the physical locations is calculated by an internally maintained table.

Shipped format

 Data areas are optimally used.  All pushes generated by defects are absorbed by the spare tracks of the inner zone.

Figure 1 PList physical format

Defects are skipped without any constraint, such as track or cylinder boundary. The calculation from LBA to physical is done automatically by internal table.

Electrical interface

Connector location

Refer to the following illustration to see the location of the connectors.

* This connector is SATA, shape of SAS connector is shown in Figure 3

Figure 2 Connector location

Signal connector

The drive uses the standard 29 pin Serial Attached SCSI (SAS) connector which conforms to the mechanical requirements of SFF 8660. The connector is expected to be used in an environment which uses a common connector structure for racking disk drives in a cabinet. The connector allows for plugging a drive directly into a backplane by providing the necessary electrical connection. Mechanical stability and device retention must be provided by a mechanism outside the drive.

Voltage and Ground Signals

The 12V and 5V contacts provide all of the voltages required by the drive. The two voltages share a common ground plane to which all of the ground contacts are connected.

Ready LED output

The drive provides an open-drain driver with 15mA of current sink capability to the Ready LED Output signal. The cathode of the LED should be connected to this signal. The LED and the current-limiting resistor must be provided by the enclosure
