Editor:- November 14, 2016 - in a recent conversation with AccelStor's President Charles Tsai I realized we were talking about more than just a single company. Every facet touched upon some significant glimmer of change in the SSD market. So I thought I'd better share some of that in a new article.


Editor:- August 18, 2016 - AccelStor today announced it has won the Best-of-Show Technology Innovation Award for its FlexiRemap software at the Flash Memory Summit 2016 in Santa Clara, California. AccelStor's FlexiRemap software (uses a global wear-leveling algorithm) to cut down on overhead, and extend SSD lifespan.

AccelStor's NeoSapphire series of 1U rackmount flash arrays
by Zsolt Kerekes - editor - StorageSearch.com - July 14, 2015

AccelStor is a relatively new name in the rackmount SSD market. The company having founded in November 2014 as a spinoff from Innodisk.

AccelStor's rackmount SSDs - which are mainly available in 1U form factor - are rebranded and enhanced versions of Innodisk's FlexiArray which was launched in 2013.

A key concept in this product line is to use modern SSD architecture - which combines controller intelligence within each drive while also leveraging strategic intelligence about the state of the flash array (data movements and reliability) at the top level array level in order to produce a reliable, fast storage system which is easy to integrate and manage as an embedded systems component.

In many ways this product line - satisfies a new trend being seen in the user community - for a product which can be managed with the minimum set of software complications and a high degree of predictability about the feature sets of future versions.

This trend towards an "industrial" style of white box flash storage array is something which we'll be seeing much more of in the next 3 to 5 years as the enterprise SSD market evolves towards standardization of software management tools and easier interchangeability among hardware solutions.

This philosophy towards treating SSD boxes as no-frills boxes which are unbundled from troublesome proprietary features which appear in one proprietary model only to disappear in the next iteration from the same supplier - is an abstraction methodology which is already being favored by many users in the cloud market and web scale organizations.

And the NeoSapphire series satisfies this need for users who are comfortable with the concept of seeing a product roadmap based on arrays of COTS SSDs which have been optimized with internal firmware to provide a simple and predictable feature set of reliability, performance and RAS.
