Introduction

This manual describes the functional, mechanical and interface specifications for the following: Seagate® SkyHawk® AI Serial ATA model drives:

• 5xxE Standard models: ST8000VE001

These drives provide the following key features:

• 7200 RPM spindle speed.
• Full-track multiple-sector transfer capability without local processor intervention.
• High instantaneous (burst) data-transfer rates (up to 600MB per second).
• Native Command Queuing with command ordering to increase performance in demanding applications.
• Perpendicular recording technology provides the drives with increased areal density.
• PowerChoice™ for selectable power savings
• SeaTools™ diagnostic software performs a drive self-test that eliminates unnecessary drive returns.
• State-of-the-art cache and on-the-fly error correction algorithms.
• Support for S.M.A.R.T. drive monitoring and reporting.
• Supports latching SATA cables and connectors.
• Tarnish-resistant components to help protect the drive from environmental elements, increasing field reliability.
• Worldwide Name (WWN) capability uniquely identifies the drive.

Note: Seagate recommends validating the configuration with the selected HBA/RAID controller manufacturer to ensure use of full capacity is supported.

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 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 th e 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 fr om www.serialata.org.

Conducted noise

Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 V line or an equivalent 15-ohm resistive load on the +5V line.

• Using 12V power, the drive is expected to operate with a maximum of 120mV peak-to-peak square-wave injected noise at up to 10MHz.
• Using 5V power, the drive is expected to operate with a maximum of 100mV peak-to-peak square-wave injected noise at up to 10MHz.

Note: Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

• Voltage tolerance Voltage tolerance (including noise): 5V ± 5% 12V ± 10%

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 are actualized. For example, Idle_b results in greater power savings than the Idle_a power condition. Standby results in the greatest power savings.

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 the 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 that requires the drive to enter the PM0: Active state (media access)
• Power on reset

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.

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 product’s reliability and data integrity.

Environmental limits

Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C).

Caution

• To maintain optimal performance drives should be run at nominal drive temperatures and humidity. Seagate does not recommend operating at sustained extreme temperatures.
• Operating at higher temperatures will reduce useful life of the product
• See Section 2.11, “Reliability” for rated MTBF device operating condition requirements.

Temperature

Operating

• 32°F to 149°F (0°C ambient to 65°C drive reported) temperature range with a maximum temperature gradient of 36°F (20°C) per hour.
• The maximum allowable drive reported temperature is 149°F (65°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.

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.

Figure 2. Location of the HDA temperature check point

Note: Image is for reference only, may not represent actual drive

Humidity

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

Relative humidity

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

Effective Altitude (sea level)

Shock and Vibration

• Shock and Vibration
  Shock and vibration measurements specified in this document are made directly on the drive itself and applied in the X, Y, and Z axis at the driv e mounting point locations.
  Shock

  • Operating
    The drive will operate without error while subjected to intermittent shock pulses not exceeding 70 Gs (read) and 40 Gs (write) at a maximum duration of 2ms.

  • Non-operating
    The drive will operate without non-recoverable errors after being subjected to shock pulses not exceeding 300g at a maximum duration of 2ms.

• Vibration

  • a. Linear Random Operating Vibration: The drive will operate without non-recoverable errors while being subjected to the random power spectral density noise specified below. ****
  • b. Random Rotary Operating Vibration: The drive will exhibit greater than 90% throughput for sequential and random write operations while subjected to the shape d random power spectral density noise specified below.
  • c. Linear Random Non-Operating Vibration: The drive will not incur physical damage or have non-recoverable errors after being subjected to the power spectral density noise specified below.

Acoustics

Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are consistent with ISO document 7779. Sound power measurements are taken under essentially free-field conditions over a reflecting plane. For al l tests, the drive is oriented with the cover facing upward.)

Table 3 Fluid Dynamic Bearing (FDB) motor acoustics

| **Idle*| Performance seek**
---|---|---
All models| 2.8 bels (typ)

3.0 bels (max)

| 3.2 bels (typ)

3.4 bels (max)

*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.

Test for Prominent Discrete Tones (PDTs)

Seagate follows the ECMA-74 standards for the measurement and identification of PDTs. An exception to this process is the use of th e absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 389-7) to discern tone audibility and to compensate for the inaudible components of sound prior to computation of tone ratios according to Annex D of the ECMA-74 standards.

Electromagnetic immunity

When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected to the radio frequency (RF) environments defined in the following table:

Reliability

Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)

The production disk drive shall achieve an annualized failure-rate of 0.44% (MTBF of 2,000,000 hours) over a 5 year service life when used in Surveillance Storage field conditions as limited by the following:

• 8760 power-on hours per year.
• HDA temperature as reported by the drive <= 40°C
• Ambient wet bulb temp <= 26°C
• Typical workload
• The AFR (MTBF) is a population statistic not relevant to individual units
• ANSI/ISA S71.04-2013 G2 classification levels and dust contamination to ISO 14644-1 Class 8 standards (as measured at the device)

The MTBF specification for the drive assumes the operating environment is designed to maintain nominal drive temperature an d humidity. Occasional excursions in operating conditions between the rated MTBF conditions and the maximum drive operatin g conditions may occur without significant impact to the rated MTBF.

However continual or sustained operation beyond the rated MTBF conditions will degrade the drive MTBF and reduce product reliability.

Maximum Rated Workload

| Maximum rate of <550TB/year

Workloads exceeding the annualized rate may degrade the drive MTBF and impact product reliability. The Annualized Workload Rate is in units of TB per year, or TB per 8760 power on hours. Workload Rate = TB transferred * (8760 / recorded power on hours).

Warranty

| To determine the warranty for a specific drive, use a web browser to access the following web page: www.seagate.com/support/warranty-and- replacements/.

From this page, click on the “Is my Drive under Warranty” link. The following are required to be provided: the drive serial number, model number (or part number) and country of purchase. The system will display the warranty information for the drive.

Preventive maintenance| None required.

HDD and SSD Regulatory Compliance and Safety

For the latest regulatory and compliance information see: www.seagate.com/support/ scroll down the page to the Compliance, Safety and Disposal Guide link.

Regulatory Models

The following regulatory model number represents all features and configurations within the series:

• Regulatory Model Numbers: STL010

Corrosive environment

Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years of exposure to light industrial environments containing sulphurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential application environment.

Users should use caution when exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold films used in hard disk drives are especially sensitive to the presence of sulphide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.

Seagate recommends that data centres be kept clean by monitoring and controlling dust and gaseous contamination. Gaseous contamination should be within ANSI/ISA S71.04-2013 G2 classification levels (as measured on copper and silver coupons), and dust contamination to ISO 14644-1 Class 8 standards, and MTBF rated conditions as defined in the Annualized Failure Rate (AFR) an d Mean Time Between Failure (MTBF) section.

Product warranty

Beginning on the date of shipment to the customer and continuing for the period specified in the purchase contract, Seagat e warrants that each product (including components and subassemblies) that fails to function properly under normal use due to defect in materials or workmanship or due to nonconformance to the applicable specifications will be repaired or replaced, at Seagate’s option and at no charge to the customer, if returned by customer at customer’s expense to Seagate’s designated facility i n accordance with Seagate’s warranty procedure. Seagate will pay for transporting the repair or replacement item to the customer. Fo r more detailed warranty information, refer to the standard terms and conditions of purchase for Seagate products on the purchase documentation.

The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at 1-800-468-3472. Users ca n also determine remaining warranty using the Seagate web site (www.seagate.com). The drive serial number is required to determine remaining warranty information.

Shipping

• When transporting or shipping a drive, use only a Seagate-approved container. Keep the original box. Seagate approved container s are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the drive warranty.
• Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in transit. Contact th e authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping by an air-ride carrier experienced in handling computer equipment.

Storage

Maximum storage periods are 180 days within original unopened Seagate shipping package or 60 days unpackaged within the defined non-operating limits (refer to environmental section in this manual). Storage can be extended to 1 year packaged o r unpackaged under optimal environmental conditions (25°C, <40% relative humidity non-condensing, and non-corrosiv e environment). During any storage period the drive non-operational temperature, humidity, wet bulb, atmospheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.

Product repair and return information

Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids the warranty.

Configuring and mounting the drive

This section contains the specifications and instructions for configuring and mounting the drive.

Handling and static-discharge precautions

After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards. Observe the following standard handling and static-discharge precautions:

Caution

• Before handling the drive, put on a grounded wrist strap, or ground oneself frequently by touching the metal chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire installation procedure.
• Handle the drive by its edges or frame only.
• The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until mounting it in the computer.
• Do not touch the connector pins or the printed circuit board.
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty. Some factory-installed labels contain information needed to service the drive. Other labels are used to seal out dirt and contamination.

Configuring the drive

Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationship. 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. Both drives behave as if they are Device 0 (master) devices.

Serial ATA cables and connectors

• The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 in). Se e Table 5 for connector pin definitions. Either end of the SATA signal cable can be attached to the driv e or host.
• For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive and the host receptacle incorporate features that enable the direct connection to be ho t pluggable and blind mateable.
• For installations which require cables, users can connect the drive as illustrated in Figure 3.

Each cable is keyed to ensure correct orientation. SkyHawk AI Serial ATA drives support latching SATA connectors.

Drive mounting

Users can mount the drive in any orientation using four screws in the side- mounting holes or four screws in the bottom-mounting holes. See Figure 4 and Figure 5 for drive mounting dimensions.

Follow these important mounting precautions when mounting the drive:

• Allow a minimum clearance of 0.030 in (0.76mm) around the entire perimeter of the drive for cooling.
• Use only 6-32 UNC mounting screws.
• The screws should be inserted no more than 0.140 in (3.56mm) into the bottom or side mounting holes.
• Do not overtighten the mounting screws (maximum torque: 6 in-lb).

Mechanical specifications

Refer to Figure 4 and Figure 5 for detailed mounting configuration dimensions. See Section 3.4, “Drive mounting.”

Note: These dimensions conform to the Small Form Factor Standard documented in SFF-8301 and SFF-8323, found at www.sffcommittee.org

Note: The image is for mechanical dimension reference only and may not represent the actual drive.

Figure 5. Mounting configuration dimensions 8TB models (Option 2 )

Note: The image is for mechanical dimension reference only and may not represent the actual drive.

Serial ATA (SATA) interface

• These drives use the industry-standard Serial ATA interface that supports FIS data transfers. It supports ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–6.
• For detailed information about the Serial ATA interface, refer to the “Serial ATA: High-Speed Serialized AT Attachment” specification.

Hot-Plug compatibility

SkyHawk AI Serial ATA drives incorporate connectors that enable users to hot plug these drives by the Serial ATA Revision 3.2 specification. This specification can be downloaded from www.serialata.org.

Caution: The drive motor must come to a complete stop (Ready to spindle stop time indicated in Section 2.4) before changing the plane of operation. This time is required to ensure data integrity.

Set Features command

This command controls the implementation of various features that the drive supports. When the drive receives this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an interrupt. If the value in the register does no t represent a feature that the drive supports, the command is aborted. Power-on default has the read look-ahead and write caching features enabled. The acceptable values for the Features register are defined as follows

Table 7 Set Features command values

• 02H Enable write cache (default).

• 03H Set transfer mode (based on value in Sector Count register).
  Sector Count register values:

  • 00H Set PIO mode to default (PIO mode 2).
  • 01H Set PIO mode to default and disable IORDY (PIO mode 2).
  • 08H PIO mode 0
  • 09H PIO mode 1
  • 0AH PIO mode 2
  • 0BH PIO mode 3
  • 0CH PIO mode 4 (default)
  • 20H Multiword DMA mode 0
  • 21H Multiword DMA mode 1
  • 22H Multiword DMA mode 2
  • 40H Ultra DMA mode 0
  • 41H Ultra DMA mode 1
  • 42H Ultra DMA mode 2
  • 43H Ultra DMA mode 3
  • 44H Ultra DMA mode 4
  • 45H Ultra DMA mode 5
  • 46H Ultra DMA mode 6

• 10H Enable use of SATA features

• 55H Disable read look-ahead (read cache) feature.

• 82H Disable write cache

• 90H Disable use of SATA features

• AAH Enable read look-ahead (read cache) feature (default).

• F1H Report full capacity available

Note: At power-on, or after a hardware or software reset, the default values of the features are as indicated above.

S.M.A.R.T. commands

• S.M.A.R.T. provides near-term failure prediction for disk drives. When S.M.A.R.T. is enabled, the drive monitors predetermined driv e attributes that are susceptible to degradation over time. If self-monitoring determines that a failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable.
• S.M.A.R.T. predictability is limited to the attributes the drive can monitor. For more information on S.M.A.R.T. commands and implementation, see the Draft ATA-5 Standard.
• SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4H) that eliminates unnecessary driv e returns. The diagnostic software ships with all new drives and is also available at:  www.seagate.com/support/downloads/seatools/.
• This drive is shipped with S.M.A.R.T. features disabled. Users must have a recent BIOS or software package that supports S.M.A.R.T. t o enable this feature. The table below shows the S.M.A.R.T. command codes that the drive uses.

Table 8 S.M.A.R.T. commands

Note: If an appropriate code is not written to the Features Register, the command is aborted and 0x 04 (abort) is written to the Error register.
