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. See also:- the evolving business case for SSD ASAPs - which has more articles and lists of suppliers.

    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.
Enmotus mentions in SSD market history

In August 2012 - Enmotus presented at the Flash Memory Summit (Aug 2011) - and was discussed in this blog - A Strategic Marketing View of Flash Memory Products by David Lamont of MarketingSage.

In November 2014 - A blog by Enmotus gave the company's view that micro-tiering within the server box - between the lowest possible latency persistent memory (such as flash backed DRAM DIMMs), then up a level to SATA SSDs and finally to hard drives - gives users materially different performance and cost characteristics to merely caching between those devices when they are used in a hybrid storage appliance.

tiering between memory systems layers
Editor:- December 8, 2016 - A new blog - Flash Tiering: the Future of Hyper Converged - by Adam Zagorski, Marketing at Enmotus - discusses how hyper-converged infrastructure has evolved along with the associated impacts from data path latency and CPU overhead. Among other things Adam notes that...

"Very soon we’ll have HCI clusters with several tiers of storage. In-memory databases, NVDIMM memory extensions and NVRamdisks, primary NVMe ultrafast SSD storage and secondary bulk storage (initially HDD but giving way beginning in 2017 to SSDs) will all be shareable across nodes. Auto-tiering needs a good auto-tiering approach to be efficient, or else the overhead will eat up performance." ...read the article

Enmotus demos hybrid arrays
Editor:- August 13, 2013 - Enmotus announced that it is demonstrating its FuzeDrive (hybrid SSD ASAP) solutions (with Toshiba SSDs inside) at the Flash Memory Summit.

"While helping accelerate early adoption of SSDs, today's caching solutions don't always provide the results users expect. FuzeDrive avoids using traditional caching techniques, and instead borrows its concepts from intelligent real time virtualization, data movement and storage pooling techniques typically found in larger 'big iron' enterprise systems," said Andy Mills, CEO and Co-founder of Enmotus.
