| aligning
database block sizes with SSDs |
Editor:- 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.
Today
I came across a recent blog by Chas. Dye at Pure Storage
called
Please
DON'T Fiddle with Your Database Block Size! - which also warns about this
very issue.
Chas says - "At Pure Storage, we believe that a factor
that should never influence the block size decision is your storage subsystem."
Editor's
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.
If an
SSD is so sensitive to
the data you hit it with - it's not the SSD you should have bought in the
first place. | | |

| Pure Storage announces $40
million funding |
In August 2012 -
Pure Storage
cranked up the heat on its funding to $95 million with a new
$40
million Series D funding round.
That's about $1 million of funding
for each system shipped since the company emerged from stealth a year ago.
Toughest
competitor - based on price - is
Skyera - although
Skyera will have to prove during the next few quarters that their recently
launched technologies work in real world installations before they become a
real headache.
Toughest competitors - based on impact of established
market presence and reputation - are
Texas Memory Systems,
Violin, and
Nimbus. | | |
