Enmotus

Enmotus was founded in August 2010 to develop solutions in the auto tiering SSD market. The company says "Enmotus provides users with their critical data when they need it. Our true tiering technology pools flash storage with traditional hard drives and dynamically moves frequently accessed data in real time to the high speed flash storage without user intervention. Responding in seconds to rapidly changing access patterns, the Enmotus solution creates a new class of affordable tiered storage that combines the capacity of hard drives with the performance of SSDs. The block based MicroTiering™ architecture provides superior read and write performance. For more information, please visit www.enmotus.com"

• editor's comments:- November 2012 - Enmotus is an SSD software company developing auto tiering technology for SSDs - which the company says will be a good fit in VM environments. The company's first product release date was originally promised to be "early 2012". Enmotus demonstrated working working versions of its fully automated MicroTiering technology (pdf) in public for the first time at the Server Design Summit (November 27, 2012).
  
  The company describes its positioning and where it thinks it fits into the enterprise SSD architecture landscape clearly in this paper.
  
  Enmotus is keen to stress the differences between tiering and caching. These differences are real - but users in complex environments typically need elements of both - and I've long believed that the end of the roadmap for such products will be to have capabilities which span both and which are architecture and applications aware. That's why in 2009 I grouped all these companies together in the category which I called SSD ASAPs - Auto-tuning SSD Accelerated Pools of storage.

  From what I can see at this early stage of disclosure - Enmotus aims to be a platform - which supports a wide range of SSDs. The company talks a lot about "HDDs" being the back end storage - which is the market for such products today. In the future - as more enterprise storage migrates to solid state - there will still be a need for this class of product. It's still too early to say - which of the 100+ contenders in the SSD ASAPs market will establish dominant market positions and survive.
