WD Enterprise WDE2170/WDE4360

Advanced Product Features

3.ADVANCED PRODUCT FEATURES

3.1.Compatibility Testing

Western Digital performs extensive testing in its Functional Integrity Test Lab (FIT Lab™). By equipping the FIT Lab with multiple host systems, adapters, operating systems, and application programs, compatibility is achieved with a broad range of applications implemented on workstations, servers, multi-user, and array systems.

3.2.SCSI-3 SPI Compliant

Drive models WDE2170 and WDE4360 conform to the SCSI-3 SPI (SCSI Parallel Interface) standard. The drives also support the Ultra SCSI performance specification and are offered in several configurations, such as Ultra Fast (8-bit, 50-pin; up to 20MB/s) and Ultra Fast Wide (16-bit, 68-pin, 80-pin SCA-2; up to 40MB/s) host transfer rates.

3.3.Embedded Servo Control

The WD Enterprise drives feature embedded servo technology to generate accurate position information on every track. An embedded servo system has servo bursts interspersed with customer data on every track. This provides a tight coupling between head positioning and customer data – a necessity for good soft error rates. In addition, embedded servo technology is less susceptible to thermal shifts of the system since customer data and position information are recorded together on the same track.

3.4.Read Caching and Pre-Fetch

Read caching allows the drive to maintain data in the cache for quick transfer to the host when a media access is not required. Pre-fetching takes place after a media access when the drive reads data into the cache that the firmware determines as likely to be requested by the host. Refer to the Western Digital SCSI Implementation Guide (document number 4096-001116) for further details.

3.5.Write Caching

Write caching gives the host the ability to allow the drive to asynchronously write data to the media while other processes may occur. Refer to the Western Digital SCSI Implementation Guide (document number 4096-001116) for further details.

3.6.512 Kilobyte Data Buffer

The entire data buffer is user accessible, enabling powerful data caching capabilities.

3.7.Adaptive Caching

The drives are equipped with an adaptive caching capability which enables them to improve performance and throughput based on how the drive is being used. Each drive determines the environment in which it is being used and optimizes the way it handles commands and data.
