DESCRIPTION AND FEATURES

General Description

Western Digital Ultrastar Capacity Enterprise hard drives offer up to 10 TB capacities and are available with SATA interface. With the highest error tolerance and MTBF of any capacity-optimized drive, Western Digital Ultrastar delivers the durability and reliability required in tightly packed vibration prone multi-drive systems. The combination of high-capacity, peak performance and robust design make Western Digital Ultrastar drives ideal for heavy workload environments, cloud storage, RAID arrays, external storage arrays, data warehousing, and mining applications.

Product Features

Serial ATA(SATA) — Serial ATA (SATA) is the next generation bus interface for hard drives. It is designed to replace Parallel ATA, and has many advantages including increased transfer rate, improved signal integrity, enhanced data protection, and hot plug support.

Time-Limited Error Recovery (TLER) — TLER prevents hard drive error recovery fallout by limiting the time the drive spends in error recovery, providing increased performance, improved availability, and lower total cost of ownership in RAID arrays.

Rotary Acceleration Feed Forward (RAFF) — These drives employ RAFF technology to maintain hard drive performance in high vibration environments through adaptive compensation of the servo system.

Perpendicular Magnetic Recording (PMR) — With PMR technology the magnetization of each data bit is aligned vertically to the spinning disk, rather than longitudinally as has been the casein hard drive technology for decades. This enables more data on a given disk than is possible with conventional longitudinal recording, and provides a platform for future expansion of hard drive densities.

IntelliSeek™ — Key product feature that calculates optimum seek speeds to lower power consumption, noise, and vibration.

Native Command Queuing (NCQ) — Performance of a random I/O workload can beimproved through intelligent re-ordering of the I/O requests so they read/write to and from the nearest available sectors and minimize the need for additional disk revolutions or head actuator movement. This improvement can be achieved though Native Command Queing (NCQ) , which is supported by these hard drives.

Pre-emptive Wear Leveling (PWL) — This feature provides a solution for protecting the recording media against mechanical wear. In cases where the drive is so busy with incoming commands that it is forced to stay in a same cylinder position for a long time, the PWL control engine initiates forced seeks so that disk lubricant maintains an even distribution and does not become depleted. This feature ensures reliability for applications that perform a high incidence of read/write operations at the same physical location on the disk.

MicroFemto Slider — These drives incorporate the next generation of femto slider form factor in which the read/write head is mounted on the small, lightweight microfemto slider that allows the head to move more quickly from track to track on the disk.

S.M.A.R.T. Command Transport (SCT) — The SCT Command Transport feature set provides a method for a host to send commands and data to a device and for a device to send data and status to a host using log pages.

World Wide Name (WWN) — The World Wide Name (WWN) defined in ATA/ATAPI-7 is a modification of the IEEE extended unique identifier 64 bit standard (EUI-64) and is comprised of three major components: naming authority, organizationally unique identifier (OUI) and serial number.

This product’s OUI is 0014EEh.

Reliability Features Set-Data Lifeguard™ — Representing the ongoing commitment to data protection, Data Lifeguard includes features that enhance the drive’s ability to prevent data loss. Data Lifeguard data protection utilities include thermal management, an environmental protection system, and embedded error detection and repair features that automatically detect, isolate, and repair problem areas that may develop over the extended use of the hard drive. With these enhanced data reliability features, the drive can perform more accurate monitoring, error repair, and deliver exceptional data security.

Power Loss Data Protection — Upon power loss, the drive utilizes stored spindle energy to back up the HDD cache to onboard flash. This allows deeper write queues which boosts performance, while minimizing data loss/corruption such as write splices that can occur during unexpected power losses.

Hot Plug Support — SATA supports hot plugging (also known as “hot swapping”), the ability to swap out a failed hard drive without having to power down the system or reboot. This capability contributes to both data availability and serviceability without any associated downtime, making it a critical feature for extending SATA into enterprise applications.

Active LED Status — The drive supports external LED requirements. It provides an activity LED output which is ON during command execution and OFF otherwise.

Fluid Dynamic Bearings (FDB) — Bearing design that incorporates a layer of high-viscosity lubricant instead of ball bearings in the hard drive spindle motor. As an alternative to conventional ball bearing technology, FDB designs provide increased non-operational shock resistance, speed control, and improved acoustics.

Staggered Spin-Up — Next generation SATA 6 Gb/s feature that allows the system to control whether the drive will spin up immediately or wait until the interface is fully ready.

CacheFlow™ —This unique, multi-generation caching algorithm evaluates the way data isread from and written to the drive and adapts “on-the-fly” to the optimum read and write caching methods. CacheFlow minimizes disk seek operations and overheads due to rotational latency. CacheFlow supports sequential and random write cache. With write cache and other CacheFlow features, the user can cache both read and write data. The cache can hold multiple writes and collectively write them to the hard disk.

48-bit Logical Block Addressing (LBA) — Western Digital SATA drives support both 48-bit and 28bit LBA and CHS-based addressing. LBA is included in advanced BIOS and operating system device drivers and ensures high capacity disk integration.

Power Management — The drive supports the ATA and SATA power management command set, allowing the host to reduce the power consumption of the drive by issuing a variety of power management commands.

Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) — S.M.A.R.T. enables a drive’s internal status to be monitored through diagnostic commands at the host level and during offline activities. S.M.A.R.T. devices employ data analysis algorithms that are used to predict the likelihood of some near-term degradation or fault conditions. When used with a S.M.A.R.T. application, the drive can alert the host system of a negative reliability status condition. The host system can then warn the user of the impending risk of data loss and recommend an appropriate action.

ATASecurity — The drive supports the ATA Security Mode Feature set. The ATA Security Mode feature set allows the user to create a device lock password that prevents unauthorized hard disk access even if the drive is removed from the host computer. The correct password must be supplied to the hard drive in order to access user data. Both the User and Master Password features are supported, along with the High and Maximum security modes. The Master Password Revision code is also supported. This feature varies by drive configuration and may not be available on all configurations.

Data Path Protection (DPP) — A feature that prevents possible electronic failures from corrupting data on the hard drive.

CacheFlow™

CacheFlow is the unique, multi-generation disk caching system. It incorporates read cache with write cache.

CacheFlow was designed to obtain maximum performance with today’s most popular operating systems and applications. CacheFlow increases performance over prior caching algorithms by increasing the number of times that requested data is in the cache. This reduces the number of host commands that require actual media access thereby improving overall drive performance.

Typical applications perform a variety of access patterns, such as random, sequential, and repetitive. CacheFlow is designed to dynamically adapt to the changes in access patterns that occur during the course of application execution.

Random mode is the default operational mode for CacheFlow. Once CacheFlow detects a sequential access pattern, it leaves random mode. CacheFlow also performs predictive read operations to increase the probability that data requested in future commands already exists in the cache.

CacheFlow partitions the buffer into multiple segments to allow for the fact that applications may access multiple non-contiguous areas on the disk. CacheFlow tracks the amount of valid data in each segment and controls the deallocation of segments to maximize drive performance.

Write Cache

CacheFlow is designed to improve both single and multi-sector write performance by reducing delays caused by seek time and rotational latency.

The write cache adaptively detects random and sequential access patterns during application execution.

If a defective sector is found during a write cache operation, that sector is automatically relocated before the write occurs.

Read Cache

CacheFlow implements a multiple segment read cache. Cache segments are assigned to read commands as they are received from the host.

Each read segment consists of pre and post read sectors in addition to the host-requested sectors. This maximizes the amount of cache data in the drive’s buffer, thereby increasing the likelihood of cache hits and improving overall performance.

Drive Mounting

Use either the four bottom screws or at least four of the side mounting screws to rigidly support the drive and prevent vibration. Some adaptor frames may not have the mechanical design structure capable of mounting the drive to meet the specified shock and vibration requirements.

The hard drive itself does not provide electrical isolation between mounting locations and drive ground connection. If electrical isolation is required, the system designer or integrator would be responsible for providing a solution.

If your system does not support hot plugging (see “Hot Plug Support on page.25), it must be turned off and unplugged before installing your hard drive.

You can mount the hard drive in the X, Y, or Z axis, depending upon the physical design of your system. For best results, mount the drive with all four screws grounded to the chassis. If all four screws are not used, see "Grounding" on page.12.

The hard drive should be mounted to the chassis using four 6-32 screws. Recommended screw torque is 5 in-lb. Maximum screw torque is 10 in-lb.

CAUTION: Screws that are too long can damage the hard drive. Hard drive screw penetration can differ between products depending upon hard drive design. Western Ditigal’s minimum design criteria is to always meet the SFF 8301 industry standard specification. The industry standard as defined in the SFF 8301 specifies a maximum of 3 mm screw penetration, and for a minimum of 2.4 mm of thread engagement from both the screw and the hard drive.

See Figure 1 for allowable fastener penetration for this product family.

The PCBA and HDA grounds are always connected together in the drive and cannot be disconnected. The drive mounting screws, unless intentionally isolated, will provide additional ground connections between the HDA and the system chassis. If the drive isn't grounded via mounting screws as described under “Hard Drive Installation” on Page.46, there may be increased electrical emissions (EMI).

Power Savings Modes

This product is capable of supporting both legacy ATA Advanced Power Management (APM) mode and the new more extensive Extended Power Conditions (EPC) standards. Unless otherwise specified, the default disk drive is shipped with the EPC mode enabled, and the legacy APM modes can be enabled via the Set Feature command (Feature ‘4A’h, Sub Command ‘04’h). These two power savings implementations are exclusively used, and thus not simultaneously supported.

This drive supports the legacy ATA power management commands that lower the average power consumption of the hard drives. For example, to take advantage of the lower power consumption modes of the drive, an energy efficient host system could implement a power management scheme that issues a Standby Immediate command when a host resident disk inactivity timer expires. The Standby Immediate command causes the drive to spin down and enter a low-power mode. Subsequent disk access commands would cause the drive to spin up and execute the new command. To avoid excessive wear on the drive due to the starting and stopping of the HDA, set the host’s disk inactivity timer to no shorter than ten minutes.

Hard Disk Drive Technical Reference Manual

Ultrastar DC HA210

Western Digital drives additionally support T13 Extended Power Conditions, as stated in the ACS-2 specification. Power savings features, normally only available in notebook drives, are now included in our Enterprise products. With these features enabled, drive power can be reduced automatically via inactivity timer, or manually via Host command. In timer based mode, the drive automatically starts reducing its power based on inactivity of commands from the Host. With progression into the idle states, the drive saves more and more power, but consequently takes longer to recover and respond to Host media commands.

A summary of the new low power modes and what the drive does in each mode is shown below:

Idle_A





Heads Floating Over Disk <10 ms recovery

Idle_B





Heads Parked <650 ms recovery

Idle_C







Heads Parked, Reduced RPM

3-15 sec recovery (see the Power Conditions Log for the drives actual recovery time) Idle_c recovery current limited to the maximum user mode power.

Standby_Y





Heads Parked, Reduced RPM

3-15 sec recovery (see the Power Conditions Log for the drives actual recovery time) Standby_y recovery can use full spin up power.

Standby_Z







Traditional standby Drive not spinning

Recovery is similar to a typical TTR (Time To Ready) for the HDD

Western Digital has added the Power Condition Log, which defines the support, enable bits, and timers for all power conditions. The power management timers start running after all Host commanded drive activity is complete, and will run during drive background operations, but do not take effect until those background operations are completed. The timer expiration min/max values are visible to the Host/ Initiator, but are rounded silently by the drive to its internal min/max values. The timer enable and timer values can be marked independently as changeable. Please note that some Host Operating Systems may be unable to take advantage of the inactivity timers, as they constantly access the Drive with writes to update a time stamp. In these situations it is advisable to extend the Idle_B timer value beyond the time interval of the writes, or to disable the timer entirely. Please see your Western Digital representative for help with questions about these features.
