Unified Storage in the SSD Age

SolidFire gets another $82 million funding
October 7, 2014 - SolidFire
it has closed an $82 million Series D round of funding, bringing its total
funding to $150 million.
Editor's comments:- The
building blocks of SolidFire's SSD systems are 1U
iSCSI rackmount SSDs
which include 10x 2.5"
SSDs. At that level it's the same as 100 or so other competing systems.
If you want fibre
channel access - you add a special 1U adapter rack to the native IP array.
So it's expensive - but keeps the unit costs of the most common building blocks
down - compared to including native unified storage in each rack. So in the case
of a big installation - it's a reasonable cost optimization tradeoff.
key difference is
software architecture and the fact they use a
architecture type of RAID
- which they call "no-RAID".
In SolidFire's no-RAID (which
is really big RAID) - the data is more widely dispersed across the drive
population than in classical (small architecture) RAID.
is much less disruption to data access and
performance when a drive
because SolidFire's software can manage upto about 100 racks as a raw storage
resource (1,000 SSD drives) - so the impact of a single drive down is small.
Users also have a high degree of flexibility as to how they micro manage
different virtualized segments of storage to meet their different QoS goals.

awareness, financial reports and online search data - intrinsically provide
different numerically weighted views of the same market. And which methodology
you prefer depends on whether your priority is in understanding the past,
present or future - and what it is you're trying to decide.
longitudinal market studies you can refine your understanding of shifting
patterns of market change and real leadership by comparing these different
types of data and correlating the movements in different time periods. So a
shift in search volume in one period may correlate to a change in revenue some
time later. Or a change in revenue or profitability might be seen to be tied to
a change in brand strength later.
The interesting thing about the SSD
market is that because the technology hasn't been standing still - it can be
shocking to compare the same list and see how it changes over a period of 3 to
5 years and to see which old names have disappeared and which new ones have
replaced them. I'm often reminded of this when I trawl back through my own
and news archives. I'm sure it's the same for many of you too.
the things we all hope to get out of these lists - is to avoid making too many
bad bets on companies and technologies which will prove to be a waste of our

projects that 8,000 PB of enterprise flash SSDs will ship in 2014.
I think the likely figure (PB of enterprise flash installed in

doesn't take adequately into account the ability of some systems vendors to ship
enterprise grade SSD racks using consumer grade flash chips (rather than using
enterprise SSD drives) due to technologies like

that should never influence the block size decision is your storage subsystem."
comments:- I'd certainly agree that trying to slavishly make your data

probably a waste of time - because unless you know the SSD designer you don't
