|Here's an easy SSD
question. What does Nimble Storage have in common with Pure Storage? |
|Editor:- November 15, 2013 - What does Nimble Storage have in
common with Pure
3 guesses allowed.
- Is it - they both have the word "storage" in their names?
Yes but that's not it. And just because we're approaching the weekend doesn't
mean we're going to lower our standards (that far). And if we were (lowering
our standards to that extent) I'd have given you a much bigger list of
companies in my opening question.
- They're both in the advanced stages of doing IPOs?
that is indeed so - but please tell me - who isn't nowadays? (Apart from those
who have already done it.) And it's not the answer I was looking for.
OK - you give up - here's the
answer I had in mind...
- Do they share VCs?
It's a valiant effort... To be honest
I haven't bothered to check. - But even supposing for a minute it were true
- it wouldn't be enough of a unique commonality at this time in the SSD market
- because you know - when it comes to
we're not talking Jane Austen. VCs are notoriously promiscuous. (And
whatever happened to only 3 guesses?)
Both Nimble and Pure are being sued by old
style computer companies who assert that when their employees joined these
irritating startups they took with them customer-centric market knowledge.
I already discussed the Pure case before so I won't repeat that here.
But although you may have known about Nimble too - known indeed days
or weeks ago - in which case congratulations on having won the quiz! - sorry
there are no prizes - and no I'm not at all offended that you read other SSD
sites too - especially if they're on the subject of
consumer SSDs -
not my shade of purple don't you know? - I have to confess that I only learned
about Nimble's pursuit by NetApp as late as this morning - and my sorry
excuse for having missed this story is I've been busy on other SSD stuff
- which you'll hear about later.
On the other hand if like me - you
didn't win the quiz despite coming to this site every day and never reading
anything else - thanks - mea culpa - normal service will be resumed as soon
as possible - and here's one of many
the the Nimble/NetApp story.
Now... another thing Pure and Nimble
have in common is names which suggest implicit virtues.
I've done a
bunch of articles already on many of the aspects of
naming SSD brands.
of which - if some product marketer out there decides to call their new product
line the "good enough - but no so good you can't afford it" enterprise
SSD range - let me know and I'll update my SSD name lists.
experts and analysts might say the "good enough - but no so good you can't
afford it" enterprise SSD line already exists - but goes by
Why's that? Because the marketing positioning gurus or the
company's founder or the vp of sales didn't think that "good enough"
was good enough. And BTW the CFO said - have you any idea what this would cost
on Google adwords?
have reasons to suspect that a skunks work SSD marketer who works in
SEO hasn't dropped
the "good enough" SSD brand idea entirely and is spending a lot of
time looking at Thesaurus.com and
synonymically related sites - while also holding another window open on
|do more tiers reduce waste?|
|Editor:- October 15, 2013 - The wastefulness of conventional storage
tiering is discussed in a recent blog -
On From Storage Tiering - by Chris M Evans, publisher
of Architecting IT - who
advocates the concept of having an infinite number of tiers so that - "each
server will be closer to receiving the performance level they need."|
goes on to say - "If we can deliver that, move the data between tiers
dynamically and fix the wasted capacity issue within each tier, then we have our
ultimate storage device." ...read
Editor's comments:- The problem with
implementing this is that the most economical way to design storage systems is
still dependent on the likely speed and capacity characteristics.
buy products and they have to understand the differences between the products
they see in the market. (That job of segmentation is just as important for
marketers to implement precisely as the
easier bits they
spend more time and money on.)
When I analyzed all the different
types of SSDs you need in the datacenter - from the architecture and use cases
point of view - I got to about 7 different types - which are distinctly
different - as described in my
SSD silos model -
which covers the spectrum from ultrafast RAM to archive solid state storage.
SSD product which has been optimized for any one of these distinct uses will
be uneconomic or less competitive for the other uses.
think infinite tiers - as proposed in Chris Evans's blog - can exist OK as
logical concepts in software
- but these infinite tiers will still have to map onto a distinct set of no
more than maybe 3 to 4 different physical SSD tiers in most customer sites.
Otherwise they will be wasteful and too expensive.
In the currently
forseeable state of semiconductor
technology - the bounds of physics and
architecture favor designs in which you know in advance what kind of use the
memory cell population in each part of your SSD is being optimized for.
for a sprint requires a different care conditioning regime to training for a
Although you can switch streams and repurpose cells
dynamically - which is what
is all about - this is done within the context of knowing which kind of race the
SSD is in from the outset. Running half a marathon fast and then dying due to
is not an attractive product option.
