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 »

  • Conflating Reliability and Endurance in SSDs

    Last week I sat through a presentation by Samsung on the evolution of their DRAM and flash business. One question raised by a journalist in the room related to the reliability of flash drives. The presenter proceeded to talk about the industry and how endurance means flash has a finite lifetime, one which now varies… Read more »

  • Dell Acquiring EMC – The Federation

    This is the second of a series of posts on the pending acquisition of EMC by Dell. One of the biggest features of the modern EMC has been the idea of a federation of independent businesses, established when EMC acquired VMware in 2004 (although public shares weren’t released to the market until 2007). EMC (more… Read more »

  • Dell Acquiring EMC – The Facts

    As I’m not a journalist, I don’t have a need to leap in and make commentary when big announcements/acquisitions are made. Instead I’ve taken the time to look at all of the comments already out there and formulate a more considered opinion. I doubt the acquisition of Dell by EMC has escaped most people’s attention… Read more »

  • PernixData FVP – Feature or Platform?

    A couple of weeks ago I was briefed on the latest technology to come out of PernixData; a software suite known as Architect, which provides insight into the I/O workload of virtual machines in a VMware vSphere environment.  The company’s previous (and still current) product is FVP, a caching software layer for the hypervisor that… Read more »

  • Standard SSDs or Custom NAND Modules?

    At VMworld last week I took part in a Tech Field Day presentation from Violin Memory, one of the earliest all-flash array start-ups.  Violin are “relaunching” the company, following on from many senior management changes and a lot of work to make their products more relevant.  One point of discussion (specifically from me) was whether… Read more »

  • Kaminario Releases K2 v5.5 With $1/GB Price Point

    Last week Kaminario Inc, a start-up vendor of all-flash storage solutions released an upgrade to their K2 platform.  The release, introduces three main new features: 3D TLC NAND, achieving a $1/GB price point (usable). Native data asynchronous replication, based on snapshots. A feature called “Perpetual Array” to take some of the operational and financial cost… Read more »

  • Flash Economics: Choosing The Right SSD

    This post first appeared on the Kaminario Blog – http://kaminario.com/blog/flash-economics-choosing-right-ssd/ At a superficial level, it’s easy to assume that all solid-state disks (SSDs) are the same. In reality, that assumption couldn’t be further from the truth. SSDs continue to evolve and are dividing into a broad product category, in much the same way that hard disk… Read more »

  • Avoiding The Forklift Upgrade – Kaminario Guest Post

    I’ve recently started working with Kaminario, an all-flash array startup vendor and will be publishing a series of posts and papers on the Kaminario site.  I’ll also be linking them here for convenience.  The first post covers scale-out architectures as a way to avoid the continual replacement of technology – the so called forklift upgrade….

  • Nutanix Goes After Private Cloud with XCP

    This week Nutanix held their .NEXT conference in sunny Miami, around plenty of anticipation for what was to be announced.  In the hyper-converged market-place there’s not a lot of love lost between the incumbents like VMware and the upstarts like Nutanix, as can be seen from recent blog posts that play on the polarisation of… Read more »
