GreenBytes / green storage - editor mentions on

Who's who in SSD? - by Zsolt Kerekes, editor - June 28, 2012

In a fast changing market like the enterprise SSD market - the first impression which a company makes on you colors the way you filter out whatever they do or say next.

And I admit that in 2010 - when I first read about GreenBytes - my impression was - this is just another SSD ASAPs company. And there are so many of those already - and their product isn't even particularly fast.

Then in February 2012 when they launched their first SSD rack - I didn't think too much of that either - because I could eaily give you a list of over 100 companies which are doing that too. OK - not so many bundling in dedupe and compression - but EasyCo was doing compression in enterprise flash SSD racks in 2007 - and WhipTail was shipping an SSD rack with embedded dedupe in 2009 - and the performance of GreenBytes' racks was so slow that they wouldn't have made the fastest SSDs list even 10 years ago.

So GreenBytes wasn't anywhere near my list of the top 20 SSD companies to keep an eye on.

But then earlier this month I was contacted by someone in the company to ask where they were in the scheme of things that our readers were looking at. I looked again at what they've been doing and reassessed them into a different places in the enterprise SSD silos.

That changes things a lot - because now - instead of viewing them as 1 of more than 100 or so hybrid SSD rack companies - they look more focused if I forget about their HDD-included systems and look at them again afresh as 1 of a much smaller number of pioneers in the SSD bulk storage / SSD archive market. (Their performance is at the low end of fast-enough and the high end of SSD archive.)

But I still wasn't too sure - so in June 2012 I asked Paul Silver - who's VP of GreenBytes in Europe if he could answer some questions for me.

Below you can see the answers I got - and they might help you to place GreenBytes more accurately in your own picture of the enterprise SSD use cases landscape too.

SSDmouse:- What percentage of your systems (worldwide) are hybrids compared to pure SSD arrays?

Paul Silver:- Because the Solidarity (SSD) is relatively new, the majority of our current installed base are using our hybrid solutions; however, we expect that to shift significantly in the coming months and years ahead as all-flash solutions are increasingly adopted.

SSDmouse:- What are you doing to qualify TLC flash to replace HDDs in your archive systems?

Paul Silver:- This is a confidential part of our architecture and as such, I am unable to elaborate.

SSDmouse:- How do you position your company relative to Skyera?

Paul Silver:- On the face of it, both companies have a similar objective namely to storage that delivers SSD performance at a price parity to SAS. The vision may by similar but the reality is quite different because GreenBytes is a mature solution with a proven storage stack that includes our patented inline deduplication that has been tried and tested for many years.

SSDmouse:- Some of your literature mentions HA. If a customer has multiple racks of your storage – does your software and architecture support the failure or replacement of an entire rack?

Paul Silver:- The HA-3000 and Solidarity range of systems are fully fault tolerant and hot swappable so in the event of a failure, just the effected component is replaced such as a fan or a drive.

Editor again:- So now, Dear Reader, you know what I know. I would place GreenBytes in these categories:- HA SSDs, bulk storage SSDs, fast-enough SSDs, SSD ASAPs and iSCSI SSDs.

And... later - acquired SSD companies.
selected GreenBytes milestones - from SSD Market History.

In September 2008 - GreenBytes emerged from stealth mode in . The company markets a range of SSD ASAPs which have been optimized for dedupe.

In February 2012 - GreenBytes launched its first pure SSD based storage array- the Solidarity is a high availability iSCSI 3U rackmount SSD with real-time dedupe and compression with upto 13.5TB raw capacity (60TB effective) and 120,000 4K IOPS performance.

In May 2012 - GreenBytes announced it has raised an additional $12 million in Series B funding which the company will use to expand sales and marketing of its iSCSI compatble rackmount SSD ASAPs.

In May 2014 - Oracle today announced it will acquire GreenBytes.

GreenBytes gets $12 million in Series B funding
Editor:- May 29, 2012 - GreenBytes today announced it has raised an additional $12 million in Series B funding from Generation Investment Management LLP with participation from Battery Ventures and GreenBytes management which the company will use to expand sales and marketing.

Editor's comments:- GreenBytes' systems are iSCSI compatble SSD ASAPs which include both SSD and HDD drives.

The company's GO OS (Globally Optimized Operating System) provides performance at a level which I would characterize as being at the slow end of fast-enough enterprise SSD storage (around 70K IOPS) but with deduplication, compression and other optimizations enabled they offer 60TB of virtual storage in a 3U rack .
"One petabyte of enterprise SSD could replace 10 to 50 petabytes of raw HDD storage in the enterprise - and still get all the apps running faster."

How big was the thinking in this SSD's design?
Does size really does matter in SSD design?

By that I mean how big was the mental map? - not how many inches wide is the SSD.

The novel and the short story both have their place in literature and the pages look exactly the same. But you know from experience which works best in different situations and why.

When it comes to SSDs - Big versus Small SSD architecture - is something which was in the designer's mind. Even if they didn't think about it that way at the time.
