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 »

    Exablox is one of those companies I’ve followed for some time and it was great to see them presenting at Storage Field Day 7 earlier this year.  The company sells a scale-out NAS platform, supporting the CIFS, SMB and NFS protocols, making it a perfect file server environment for small and medium enterprises. Technology View… Read more »

    According to Jared Rinderer, via an article that appears in Storage Newsletter, Cisco is on the verge of making a bid to acquire Nutanix, a vendor of hyper-converged systems.  The rumour has been quashed by none other than Nutanix CEO Deeraj Pandey, via an article on The Var Guy website.  In fact, Pandey intimated that… Read more »

  • Why VSAN and VVOLs are Not Software Defined

    Every so often another attempt is made by the vendor community to put a definition to what we call “software defined storage” or SDS.  The current discussion is on VMware Virtual SAN (VSAN) and VVOLs, software features focused on storage within the vSphere hypervisor ecosystem. This seems like a good opportunity for me to review what… Read more »

  • vSphere vDS SPAN port with Wireshark in 2 minutes

    I often find myself searching for facts to dispel “hearsay” and guesswork in troubleshooting discussions between the Network and Windows VM teams.  This article is intended to show just how straightforward it is to use the VMware distributed switch SPAN port capability, to put a virtual sniffer on a virtual port on a virtual distributed… Read more »

  • Latency Matters for (All-Flash) Storage Arrays

    Yesterday NetApp announced the latest product in their interim EF-series all-flash array range, the EF560.  This new appliance claims to be faster and offer more performance than the previous model, as demonstrated by NetApp’s SPC-1 performance results and naturally the company seem quite pleased about it.  Although the EF560 isn’t the fastest platform available, it is… Read more »

  • EMC, ScaleIO and The VMkernel

    There’s been a bit of conversation recently on the intention of EMC to put drivers for their ScaleIO platform into the VMware ESXi hypervisor kernel.  The discussion was triggered by an article published in LeMagIT on 25 November 2014 by Christophe Bardy and subsequently picked up by The Register.  It implied that VMware and EMC were… Read more »

  • What Next for Storage in 2015?

    Sometimes it’s hard to believe that there’s anything more to achieve in data storage.  Surely things are pretty much complete; we have the ability to store vast quantities of data reliably and each year the per unit cost of storage continues to decline.  So as 2015 rolls in, is there anything left to achieve?  What… Read more »
