In the first wave of solid-state storage arrays, we saw commodity style SSDs
(solid state drives) being added to traditional storage arrays. This solution
provided an incremental benefit in performance over spinning hard drives,
however the back-end technology in these arrays was developed up to 20 years
ago and was purely focused around driving performance out of the slowest part
of the infrastructure – the hard drive. Of course SSDs are an order of
magnitude faster than HDDs so you can pretty much guarantee SSDs in
traditional arrays results in underused resources, but is premium priced.
Wave 2 of SSD arrays saw the development of custom hardware, mostly still
continuing to use commodity SSDs. At this point we saw full exploitation of
the solid state capabilities, with architecture designed to provide the full
performance capabilities of solid state drives. Thes... (more)
Probability says that with an infinite number of monkeys and typewriters
given an infinite amount of time, at some stage the monkeys will produce the
entire works of Shakespeare. According to this BBC News article, a programmer
in the US has tried to do just that, using AWS (Amazon Web Services).
He’s created virtual monkeys that run on AWS instances, typing out
fragments of the great Bard’s collected works.
It sounds like a great thing to do, however maths is against him. With 26
letters, doubled for upper and lower case, plus maybe a dozen punctuation
symbols and the space, e... (more)
It’s pretty easy to pick holes in the current legacy storage products,
especially when it comes to integration within both public and private cloud
deployments. However it’s worth discussing exactly what is required when
implementing cloud frameworks, as the way in which storage is deployed is
radically different from the traditional model of storage operations. In
this post we will look at why traditional methods of storage management need
to change and how that affects the way in which the hardware itself is used.
This leads to a discussion on APIs and how they are essential... (more)
In a previous post, I touched on the need to have APIs for managing storage
in cloud environments. In this post, I’ll talk about how the way in which
storage is deployed in cloud environments has to change.
For the last 10 years, the advent of Storage Area Networks (SANs) has created
a storage-centric view of the world with storage at the centre and the
“planets” – networking and servers – wrapped around it like some
pre-Copernican view of the universe. Over time, SANs have evolved to be
ever bigger, with some organisations deploying huge fibre channel fabrics.
As we’ve seen ... (more)
August seems to have been the month for a huge raft of storage-related
announcements and I’m still getting to grips with the detail, after being
away on holiday for the whole month. As I start to pick out the news and
make sense of how it fits into the storage landscape, I thought I’d start
with a few straightforward ones to ease me back into things gently.
Pure Storage FlashArrays were originally Fibre Channel only devices (see my
review after TFD#8 last year). In today’s unified world, that could be
seen as somewhat limiting, so Pure have announced support for iSC... (more)
