WD Datacenter HDD Technology

Datacenters are building out at an incredible rate to keep up with the tremendous growth of data. A 42U storage rack may include over 900 drives, providing almost 3 PB of storage. A system that contains many drives needs to be specially designed with features and technologies that ensure reliability, scalability, high availability and deliver consistent levels of performance. However, some of these features and technologies create challenges for hard drives – environmental, compatibility and workload challenges.

Here is a deeper look at these challenges and a explanation of how hard drives need to be designed for enterprise-class datacenter and cloud storage environments. Needless to say, datacenters present challenging environments for hard disk drives, and therefore require a fundamentally different class of drive – an enterprise-class drive.

Challenge #1: Environment

The datacenter environment employs specialized server and storage systems containing high-speed fans, densely-packed drives and temperature fluctuations.

IT Concerns:

  • High-speed fans are necessary to manage thermals but generate a wide range of vibrations
  • Densely-packed drives induce vibration on each other, potentially causing system-level performance degradation
  • Redundant power supplies reflect the multiple fail-over technologies that ensure 24/7 operation
  • Datacenter geographical location and cooling solutions vary, creating temperature and altitude extremes

WD's solution: A storage portfolio built to withstand harsh datacenter conditions.

  • RAFF + tied shaft motors are designed to compensate for multi-drive enclosures while ensuring consistent levels of performance
  • Higher quality components - designed for 24/7/365 operation (8,760 power-on hours per year)
  • High reliability with class-leading 5-year enterprise-grade warranty
  • Support for a wide range of temperature and altitude ratings


Challenge #2 Compatibility

Datacenters require different host bus adapters and fault-tolerance schemes like RAID and replication to ensure maximum performance, manageability and availability of a large amount of storage space.

IT Concerns:

  • RAID-based arrays demand high performance, tight performance variation, high error tolerance, and multiple interface options
  • Replication-based systems deliver high levels of data availability vs. traditional RAID and can tolerate lower reliability and lower performing devices
  • IT managers require interoperability across a wide range of host bus adapters that are deployed within their datacenters

WD's solution: Storage devices that work flawlessly with hundreds of different controllers in both RAID and replication arrays.

  • Higher error tolerances, tight performance variation, and SAS and SATA options for RAID systems
  • Datacenter quality products with right-sized error rates and performance that are optimized for replicated systems
  • Broad HBA compatibility including functional and signal-integrity testing also tuned and optimized for system interoperability

RAID-based array and Replication array

Challenge #3 Workload

Datacenter and cloud storage systems use a wide variety of operating systems and applications that need to work flawlessly with their chosen device. Workloads are typically ten times greater than the workload of desktop or notebook computers and the storage devices must be able to handle workload-intensive applications 24 hours a day, 365 days a year.

IT Concerns:

  • Applications have varying workloads – heavy reads or writes, sequential or random performance, low latency
  • Some datacenter applications require 100% workload, 24 hours per day, 365 days per year
  • OEMs are typically not aware of the types of workloads being employed on systems they sell

WD's solution: Storage devices that work flawlessly with hundreds of different controllers in both RAID and replication arrays.

  • Higher RPM models for performance demanding applications
  • Products are designed for 8,760 power-on hours per year, reading and writing continuously

  • Specialized manufacturing and test processes

WD Surveillance Storage:

WD Surveillance StorageSafety and security are always a concern. Governments, corporations and even individuals must protect themselves and their assets. One of the most popular methods employed to enhance security and safety is with video – one of the most storage-intensive fi le formats around. As the affordability of high-defi nition surveillance cameras has declined and their widespread use has been adopted, the demand for reliable and scalable storage has skyrocketed. As a result - according to IHS - the market for enterprise storage solutions in security is forecasted to grow by a 14.8% compound annual growth rate (CAGR) over the next fi ve years.1 As evidenced by the data, increased presence and enhanced requirements of modern surveillance systems, there is a pressing need for specialized hard drives that offer more storage capacity and advanced features designed specifi cally for DVRs, NVRs, CCTV, IPTV and other surveillance mediums.

Understanding today’s surveillance market

The surveillance market is splitting into two primary types of systems; DVR – primarily analog systems that have cameras directly connected to the system, and NVR – digital systems that have cameras connected via IP (internet protocol). Due to the fact that DVRs have a finite number of cameras that can be physically attached, the number of streams and maximum workload on the hard drives can be determined. Since NVRs theoretically can have an unlimited number of cameras attached to the system, the number of streams, workload on the hard drive, and the system’s retention period can scale beyond that of a DVR.*

*There are limitations, primarily tied to system capability, so NVRs are not infinitely scalable.

Choosing the right surveillance-class drive

WD offers a complete line of surveillance-class storage designed for home, small to medium business or mission critical security systems. These hard drives are engineered to support the rigorous 24/7, always-on, high-definition video requirement set unique to surveillance security systems.
