NetApp has shipped 59PB of SSDs in past 3 years
November 19, 2013 - Among other things - Network Appliance
it has has shipped over 59 petabytes of flash storage in the past 3 years.
comments:- What NetApp actually said was "over 60PB to date".
My calculation goes like this...
The company shipped 1PB in
its first year in the SSD market - which ended in the 3rd quarter of
it's shipped approximately 60PB in 3 years. Probably more than 1/2 of that will
have been in the past year.
How does that compare with others?
It doesn't sound like a lot in the context of today's market.
to a (quirkily pro-HDD)
by Toshiba - the
analyst data which
projects that 8,000 PB of enterprise flash SSDs will ship in 2014.
I think the likely figure (PB of enterprise flash installed in
systems) will be much higher than even that - because Toshiba's data probably
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

aligning database block sizes with SSDs
February 5, 2013 - I often hear from readers designing
software for SSDs who
- having researched the subject of
flash etc - have
spent too much time over-worrying about internal SSD hardware details that
they really shouldn't be worrying about. Because by the time they learn about
such things - that type of hardware anxiety is ancient history.
I came across a recent blog by Chas. Dye at Pure Storage
DON'T Fiddle with Your Database Block Size! - which also warns about this
Chas says - "At Pure Storage, we believe that a factor
that should never influence the block size decision is your storage subsystem."
comments:- I'd certainly agree that trying to slavishly make your data
structures look like something you've read about which might be inside an
SSD controller is
probably a waste of time - because unless you know the SSD designer you don't
really know what's going on - and the abstraction you read about in some web
site is only a small part of the picture.

the data you hit it with - it's not the SSD you should have bought in the

Nutanix has a new NFS for PCIe SSD accelerated CPUs

NetApp acquires Engenio
Editor:- March 9, 2011 -
announced that it has entered into a definitive agreement to purchase the Engenio external
storage systems business of LSI for $480 million.
The close is anticipated to occur in approximately 60 days subject to
customary closing conditions.
Engenio will enable NetApp to address
emerging and fast-growing market segments such as
full-motion video capture and digital video surveillance, as well as high
performance computing applications, such as genomics sequencing and scientific
research. NetApp has the channel reach and customer relationships today that
require high performance and big bandwidth capabilities that will be well served
by Engenio's storage platform. NetApp says these segments are expected to
collectively represent a $5
billion incremental market opportunity by 2014.
comments:- LSI has been trying to sell off Engenio since 2004. NetApp will
love them more. For a brief time this past week - searches for Engenio exceeded
that for "SSD". In the previous decade over
