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 »

  • More Thoughts on Storage Performance – Measuring with Load DynamiX

    In a previous post, I wrote about how improvements in storage performance have been achieved through changes to software.  Vendors like DataCore and Nutanix have implemented significant improvements that are in some cases quite remarkable.  As the storage market diverges into dozen’s of vendor platforms, how can end users validate the claims vendors are making?  Verifying vendor… Read more »

  • Fixing Storage Performance with Software

    This week I’ve had two interesting briefings that talked about significant storage performance improvements which have been achieved through storage updates.  The first was from DataCore, a long time storage virtualisation company that has been in the industry for 20 years.  The second was from Nutanix, which released a series of updates as part of AOS 4.6… Read more »

    Update: The day after this post was released, VMware issued a clarification post on the Virtual Blocks website.  The post pretty much summarises what is written here, with a little more detail, although it doesn’t look like erasure coding in VSAN will be extended past the 3+1 and  4+2 schemes.  You can find the post… Read more »

  • Hyper-convergence and Private Cloud

    Hyper-convergence has been one of the biggest IT trends of the last 24 months, with start-ups and existing technology vendors offering a suite of hardware and software solutions.  Many have conflated hyper-convergence and private cloud to mean one way of deploying and managing IT infrastructure and applications.  Although there are many similarities between the two… Read more »
