Kaminario Goes Software-Defined

Kaminario recently announced that the company is moving to a software-based business model.  Rather than build and support storage arrays, Kaminario will partner with Tech Data for logistics and essentially focus on the software part of their offering.  Is this an admission of defeat or a sign of the times? A Hardware History Kaminario has… Read more »

Data Mobility – Caching Technologies

This is one of a series of posts looking at data mobility for the hybrid cloud. You can find a link to all of the published articles as they become available here.  (link). Caching is not a new technology.  In fact, it’s been used as a technique to cost-effectively accelerate I/O performance since computers were… Read more »

Object Storage Critical Capabilities #3 – Searching, Indexing and Metadata

This is the third in a series of posts covering object storage requirements.  Other posts in this series can be found at Object Storage Capabilities Series. Object stores are intended to store large volumes of data.  Capacities are usually measured in hundreds of terabytes or petabytes rather than smaller units.  As a result, an object… Read more »

Public Cloud is Still Hardware Focused

Microsoft Azure has recently announced that the latest AMD EPYC processors will be available on a range of Azure compute instances.  The new instances are storage optimised, meaning they are aimed at high I/O workloads.  This isn’t surprising because the EPYC processors have typically 2-3 times more bandwidth capability than their Intel Xeon counterparts.  With… Read more »

Technology Choices for Data Mobility in Hybrid Cloud

Over the past 12-18 months, I’ve done a lot of work looking at options for getting existing data into the public cloud.  You may have noticed that I’ve talked a lot about the subject over this period.  There are links at the end of this post to that content.  However, I thought it might be… Read more »

The Impact of Meltdown/Spectre for Storage & HCI

Edit: Chris Mellor at The Register has some additional comment from vendors, including Scale Computing. (link).  Further Register emails (link) point to significant slow downs in workload.  And here’s another post regarding the need (or not) to patch storage appliances. Unless you’ve been 100% disconnected from technology (and the Internet) over the last few days,… Read more »

Do you have feedback on what you would like to see in 2018?  Please take less than two minutes to answer our really quick 5 question survey! – link A quick look at the adoption of technology over the last 60 years shows us that no one vendor, technology or concept becomes 100% dominant.  Back… Read more »

Seagate Pre-announces Multi-Actuator Drives

When your technology is based on mechanical motion, it’s inevitable that at some point the laws of physics will get in the way.  This has been a problem for hard disk drives for some time.  Spin speeds never exceeded 15K RPM except in some test drives.  As a result, throughput has been limited by this… Read more »

  • Getting Started With Docker

    In my previous post, I talked about how Docker fits in with workload virtualisation.  In this post, I’ll look at getting started with Docker itself. Installation In this post I’ll look at the basics of installing Docker and creating a container.  I’ll reference the CentOS distribution initially, with more added as I validate and test… Read more »

  • Cloud as a Tier of Storage

    In my last post I talked about storage tiering and how it has evolved with the advent of new technology and of course the arrival of flash storage to mainstream deployments.  One of the comments on that post indicated that I’d excluded Cloud as a tier of storage.  Now, there are two ways to look… Read more »

  • Understanding Tiered Storage

    This week I noticed a conversation taking place on Twitter discussing the subject of tiered storage.  The understanding of why tiered storage developed and why it is used today seems to be somewhat misunderstood, so perhaps it’s time for an update on this technology. Background Given infinite resources and infinite budget, all data would be… Read more »

  • Using SSD for Write-Intensive Workloads

    Yesterday I appeared as a guest speaker on a BrightTalk Webinar covering storage for Big Data.  One subject raised was the suitability of flash (SSD) over hard drives for write-intensive workloads.  The comments from another speaker implied that SSDs aren’t good with write intensive workloads as this wears the devices out too quickly.  Hard drives… Read more »

  • Containers vs Virtualisation

    With the announcement of the release of Docker 1.0, Linux Containers are one of IT’s current hot topics.  How does Docker and Containers in general fit into the world of virtualisation and is the technology simply riding a hype curve? Background The idea of containers isn’t a new one.  Sun Microsystems’ Solaris operating system introduced… Read more »

  • EMC Acquires DSSD – But for What?

    One of the interesting announcements from the recent EMC World event in Las Vegas was the news that EMC are acquiring stealth startup DSSD.  Not a great deal is yet known about this company, as they are not currently shipping any product (and presumably don’t have any existing customers).  However we do have a few… 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 »
