www.seagate.com Introduction

1.1 About the Serial ATA interface

The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include:

 Easy installation and configuration with true plug-and-play connectivity.

It is not necessary to set any jumpers or other configuration options.

 Thinner and more flexible cabling for improved enclosure airflow and ease of installation.  Scalability to higher performance levels.

In addition, Serial ATA makes the transition from parallel ATA easy by providing legacy software support. Serial ATA was designed to allow users to install a Serial ATA host adapter and Serial ATA disk drive in the current system and expect all of the existing applications to work as normal.

The Serial ATA interface connects each disk drive in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave relationship with Serial ATA devices like there is with parallel ATA. If two drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. This essentially means both drives behave as if they are Device 0 (master) devices.

NOTE The host adapter may, optionally, emulate a master/slave environment to host software

where two devices on separate Serial ATA ports are represented to host software as a Device 0 (master) and Device 1 (slave) accessed at the same set of host bus addresses. A host adapter that emulates a master/slave environment manages two sets of shadow registers. This is not a typical Serial ATA environment.

The Serial ATA host adapter and drive share the function of emulating parallel ATA device behavior to provide backward compatibility with existing host systems and software. The Command and Control Block registers, PIO and DMA data transfers, resets, and interrupts are all emulated.

The Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For additional information about how Serial ATA emulates parallel ATA, refer to the “Serial ATA: High Speed Serialized AT Attachment” specification. The specification can be downloaded from www.serialata.or

2.5.4 Extended Power Conditions - PowerChoice™

Utilizing the load/unload architecture a programmable power management interface is provided to tailor systems for reduced power consumption and performance requirements.

The table below lists the supported power conditions available in PowerChoice. Power conditions are ordered from highest power consumption (and shortest recovery time) to lowest power consumption (and longest recovery time) as follows: Idle_a power >= Idle_b power >= Idle_c power >= Standby_z power. The further users go down in the table, the more power savings is actualized. For example, Idle_b results in greater power savings than the Idle_a power condition. Standby results in the greatest power savings.

Power Condition Name Power Condition ID Description

Idle_a 81

Idle_b 82

Idle_c 83

Standby_z 00

Reduced electronics

Heads unloaded. Disks spinning at full RPM

Heads unloaded. Disks spinning at reduced RPM

Heads unloaded. Motor stopped (disks not spinning)

Each power condition has a set of current, saved and default settings. Default settings are not modifiable. Default and saved settings persist across power-on resets. The current settings do not persist across power-on resets. At the time of manufacture, the default, saved and current settings are in the Power Conditions log match.

PowerChoice is invoked using one of two methods

 Automatic power transitions which are triggered by expiration of individual power condition timers. These timer

values may be customized and enabled using the Extended Power Conditions (EPC) feature set using the standardized Set Features command interface.

 Immediate host commanded power transitions may be initiated using an EPC Set Features "Go to Power

Condition" subcommand to enter any supported power condition. Legacy power commands Standby Immediate and Idle Immediate also provide a method to directly transition the drive into supported power conditions.

PowerChoice exits power saving states under the following conditions

 Any command which requires the drive to enter the PM0: Active state (media access)  Power on reset

Seagate IronWolf Pro SATA Product Manual, Rev. F 12

PowerChoice provides the following reporting methods for tracking purposes

Check Power Mode Command

 Reports the current power state of the drive

Identify Device Command

 EPC Feature set supported flag  EPC Feature enabled flag is set if at least one Idle power condition timer is enabled

Power Condition Log reports the following for each power condition

 Nominal recovery time from the power condition to active  If the power condition is Supported, Changeable, and Savable  Default enabled state, and timer value  Saved enabled state, and timer value  Current enabled state, and timer value

S.M.A.R.T. Read Data Reports

 Attribute 192 - Emergency Retract Count  Attribute 193 - Load/Unload Cycle Count

PowerChoice Manufacture Default Power Condition Timer Values

Default power condition timer values have been established to assure product reliability and data integrity. A minimum timer value threshold of two minutes ensures the appropriate amount of background drive maintenance activities occur. Attempting to set a timer values less than the specified minimum timer value threshold will result in an aborted EPC "Set Power Condition Timer" subcommand.

Power Condition Name Manufacturer Default Timer Values

Idle_a 100 ms

Idle_b 2 min

Idle_c 4 min

Standby_z 15 min

Setting power condition timer values less than the manufacturer specified defaults or issuing the EPC "Go to Power Condition" subcommand at a rate exceeding the default timers may limit this products reliability and data integrity.

a. Operating

41°F to 140°F (5°C to 60°C) temperature range with a maximum temperature gradient of 36°F (20°C) per hour as reported by the drive.

The maximum allowable drive reported temperature is 140°F (60°C). Air flow may be required to achieve consistent nominal drive temperature values (see Section 3.4). To confirm that the

required cooling is provided for the electronics and HDA, place the drive in its final mechanical configuration, and perform random write/read operations. After the temperatures stabilize, monitor the current drive temperature using the SMART temperature attribute 194 or Device Statistics log 04h page 5.

b. Non-operating

–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification assumes that the drive is packaged in the shipping container designed by Seagate for use with drive.

2.6.2 Humidity

The values below assume that no condensation on the drive occurs. Maximum wet bulb temperature is 84.2°F (29°C).

2.6.2.1 Relative humidity

Operating: 5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.

Nonoperating: 5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.

2.6.3 Effective Altitude (sea level)

Operating: –304.8 m to 3048 m (–1000 ft. to 10,000+ ft.)
