Has NVMe Killed off NVDIMM?

Update: I’ve added extra links at the end of this post, covering some background reading/watching from SNIA. According to a recent article on The Register, Diablo Technologies appears to have closed down.  Diablo was or is a manufacturer of NVDIMM and DRAM extension technology, including Memory1.  As previously reported, many of the original founders and… Read more »

Public Cloud Comparisons – Account Creation

I’m doing a little more structured work with public cloud, so have been going back and cleaning up and standardising the existing accounts I already have.  The first thing is to create accounts that are company, not user specific.  I like to use distribution groups or mailing lists for setting up accounts.  They are more… Read more »

Delivering File Protocols on Object Stores

When object stores first started to appear on the market, the aim was to target a very specific niche.  Unstructured data growth demanded better ways of storing data than file servers.  Object stores offered the ability to scale to billions of objects, without the issues of managing a file system.  However, rewriting applications for REST-based… Read more »

Is Private Cloud Dead?

Anyone who followed the announcements at AWS re:INVENT last week will have seen a clear theme that covered most of the announcements made at the event.  AWS is focused on bringing services to the public cloud that concentrate on machine learning, AI and generating insight from large volumes of data.  The AWS team seems to… Read more »

Four Platforms When One Will Do?

One of the more interesting discussions from SFD14 was the review of the various mid-range platforms that Dell EMC now offers.  The merger of the two organisations brought Unity and VNX(e) from EMC, while SC (Compellent) and EqualLogic came from the Dell side.  Each platform has very different characteristics.  Unity and VNX(e) have heritage from… Read more »

VMware on Azure? Great! Or Maybe Not

In recent days we’ve heard that Microsoft will assist VMware users in moving their workloads to Azure.  For the more “difficult” applications, customers can choose to simply run applications on vSphere hosted on the Azure platform.  This service will be delivered in conjunction with VMware-certified partners.  In response, VMware has released a blog indicating that… Read more »

Is NetApp Becoming A Service Provider?

One not-so-obvious presentation at NetApp Insight in Berlin (November 2017) was the announcement of NetApp Cloud Orchestrator.  This is a tool to manage not only storage but also compute resources across public cloud providers.  The technology comes from the acquisition of Greenqloud earlier this year. Joe CaraDonna presented the use of Cloud Orchestrator on-stage to… Read more »

HPE Brings Nimble Skynet to 3PAR Arrays

Who doesn’t like the idea of having six 9’s of uptime for their storage?  Availability is a major consideration for any storage, public or private.  Of course, having great availability isn’t the only measure of storage quality.  We also value performance, low latency and consistency.  But making storage behave in a predictable manner isn’t always… Read more »

Accelerating Workloads with NetApp Plexistor

I hadn’t realised that NetApp acquired Plexistor earlier this year.  Depending on which site you look at, the acquisition was a pretty cheap $20m or $32m, based on an A-round investment of around $4.5m in September 2014.  NetApp demonstrated application acceleration using the Plexistor technology at Insight in Berlin last week (see the day 2… Read more »

VMAX – The Mainframe of Storage

This post title may sound a little controversial, but that’s far from my intention.  Anyone who knows me will be aware that I started out in the mainframe era.  I like the mainframe’s reliability and maturity of features, many of which took a long time to arrive in today’s IT world.  However, the mainframe is… Read more »

  • EMC takes on Google and Amazon with Elastic Cloud Storage

    One of the more interesting announcements from EMC World 2014 last week was a new platform from EMC called Elastic Cloud Storage (ECS).  ECS is the “productisation” of the previously announced Project Nile, which I discussed last year.  At the time, the indications were that Nile was some kind of packaged VNX solution sold in… Read more »

  • Flash Shipment Bragging Rights (Updated)

    There’s a lot of “willy waving” comments being thrown around at the moment regarding flash storage shipments.  The news from one vendor is barely out before another is claiming they have already exceeded those figures.  So what are the claims, can we assume any facts and of course does any of it matter? I’ve done… Read more »

  • Has NetApp Reached a Strategic Inflection Point?

    Chris Mellor recently covered IDC’s quarterly disk shipment report, which measures the market leaders in enterprise storage.  As Chris points out, NetApp continues to decline, with reduced revenue over the last three quarters.  I’ve talked for some time about NetApp reaching an inflection point with Data ONTAP, their storage array operating system.  Has the legacy of… Read more »

  • VMware’s Virtual and Physical SAN Misdirection

    I almost fell off my chair laughing as I read this post by Chuck Hollis that talks about using vSphere VSAN (Virtual SAN) with external storage arrays.  Is it the rantings of someone clinging onto the vestiges of a former life, or perhaps it’s a veiled way for VMware to start unravelling their failed VVOL… Read more »

  • XtremIO: What You Need to Know (Updated)

    With much anticipation, EMC has finally gone GA on their all-flash array, XtremIO, based on the former company of the same name they acquired in May 2012.  The eighteen months that have elapsed since then has seen the rise of an number of competitors and a lot of rumour, discussion and teaser presentations from EMC… Read more »

  • Storage QoS In The Cloud

    Last year I did some research and wrote up a couple of posts on Cloud Compute performance.  One feature that seems to get left out somewhat is storage I/O performance; the cloud offerings talk about capacity, but rarely reference performance. Recently, I reviewed the options available from the major providers and found two new storage performance offerings…. Read more »

  • Is Google Drive Too Late to the Party?

    Like many people, the other week I downloaded and installed Google Drive.  This is the long-awaited competitor to services like Dropbox and Microsoft’s SkyDrive.  It offers free online storage with the ability to upgrade to higher capacity at a cost.  Dropbox and the various other lookalikes have been around for some time, so is Google… Read more »

  • Why Does Microsoft Hyper-V Not Support NFS?

    I recently wrote an article covering storage for virtualisation and was surprised to find out that Microsoft does not support the use of NFS shares with Hyper-V.  At first I thought perhaps I was doing something wrong and that my configuration was in error.  But after a lot of lab testing and eventually finding some… Read more »

  • NetApp: The Inflexibility of Flexvols

    I’ve just been reading up on Data ONTAP 8.0 as part of some ongoing work I’m doing.  You may be aware that version 8.0 of the filer operating system brings two major features; 64-bit support and the (sort of) integration of the Spinnaker code to create the multi-node version of ONTAP (called cluster mode). The… Read more »
