All-Flash Array: A Unique Concept

An All-Flash Array is a data storing mechanism that uses several flash memory drives rather than using spinning disks, allowing much faster data transfer rates, and more efficient use of data center resources (i.e. rack space, power, cooling, and staffing etc).

An All-Flash Array, is also known as Solid State Array. When the term “All-Flash Array” is used, it is generally compared to other data storage such as spinning media, or currenty, Hybrid Flash Arrays, which are a combination of both Flash and spinning media. All-Flash storage uses non-moving parts, which produces less heat generated, less power utilization, and less maintenance. From a practical point of view, All-Flash technology (and the Flash array in general) provides vastly superior performance; less spikes in latency, improved disaster recovery, support of real-time analytics, much faster data transfer, and the ability to spare IT personnel to concentrate on other tasks. All-Flash Arrays provide the foundation for next-generation corporate and business applications, and the All-Flash data center.

The most apparent value of using flash in the array is in delivering very high I/O capability. Typically, devices on the market are capable of delivering from 500K up to one million input/output operations per second (IOPS) in a single impression, with latency figures of one millisecond or less.

Key Benefits of All-Flash Array

All-Flash Arrays offer sufficiently other benefits as well. They can:

  • Allow extraordinary data-mobility speeds, enabling data to be shared and accessed across functions.
  • Prevent spikes in latency as more users access the data.
  • Allow organizations to easily move away from traditional disk storage to Flash storage.
  • Easy to manage, so allow IT managers to move their staff to focus on more strategic activities.
  • Support faster, even real time, analytics — which, in turn, creates new decision-making power and business opportunities.
  • Reduce replacement costs.
  • Contributing in data center management by significantly reducing heat, power, cooling, and physical footprint required for traditional arrays while eliminating ambient noise and vibration.
  • Ultimately, increase competitive advantage by speeding up time-to-market for data-driven businesses and providing better, faster service to users.

Choosing an All-Flash Array

It might seem counter-intuitive to say that all-flash arrays are less expensive than hybrid arrays or traditional hard disk arrays, but it all comes down to what’s most important. If your application requires instant access and zero latency, you cannot ask for a better option than all-flash storage.

Today’s flash technology, joined with the tendency to virtualize servers, is changing the way storage is designed into systems. What remains to be seen is how well the new class of all-flash arrays stand up over time as high-performance applications put the longevity of flash storage to the test.
