Pure Storage AIRI – CI for AI

Machine Learning and Artificial Intelligence (ML/AI) are two of the biggest buzzwords in the tech industry at the moment.  The technologies have wide application, much greater than the often-repeated stories about self-driving cars.  ML/AI solutions can be used in healthcare to improve diagnostics.  It has applications across the financial world, allowing companies to be more… Read more »

Is Your Flash Storage Riding the DRAM Curve?

The rate of growth in flash media is truly incredible.  In ten years, we’ve gone from highly expensive SLC devices to a range of NAND flash media for all requirements.  Flash manufacturers continue to push the boundaries, with 30TB and 100TB drives already on the market.  With no end to this growth in sight, how… Read more »

Why Deterministic Storage Performance is Important

In the days of spinning media, I/O performance was anything but consistent.  When mechanical head movement is involved, response time can vary enormously.  Actually, the variation of I/O isn’t just to do with mechanics as we will discuss in a moment.  However, inconsistent I/O response time is a problem for applications and as tolerances reduce,… Read more »

Samsung Introduces 8TB NF1 NVMe SSDs

Samsung has recently announced an 8TB NF1 format NVMe SSD.  NF1 was originally called NGSFF (Next Generation Small Form Factor) and is intended as a replacement for the existing M.2 format drives.  With 15K and 10K drives disappearing from the market, is it time to accept we should move on from legacy HDD drive sizes?… Read more »

Avoiding the Storage Performance Bathtub Curve

We’re probably all familiar with the concept of the HDD or SSD reliability bathtub curve (figure 1).  This shows how over the lifetime of a drive, failures typically follow a pattern where failure rate increases over time to a steady state, then increases again as the device wears out.  But have you considered the idea… Read more »

The Britpop Battle of Rubrik and Cohesity

Were you a Blur or Oasis fan?  Perhaps you were on the side of Jarvis Cocker and preferred Pulp.  Whatever your choice, the Britpop wars of the 1990s were memorable for building hype around the UK music industry and the idea of Cool Britannia. In lots of ways, the evolution of the data protection industry… Read more »

NVMe over Fabrics – Caveat Emptor?

For the past 20 years, Fibre Channel has been the dominant enterprise data centre storage networking technology.  By this, I mean traditional Fibre Channel, not variants that work over IP or use Converged Ethernet (more on that in a moment).  It’s true that other protocols exist.  Smaller organisations have typically used iSCSI, because of the… Read more »

IDC 1Q2018 Data Shows a Rebound for Storage Hardware Sales

The latest IDC Storage Tracker numbers are out and in the spirit of recent analysis, I’ve put the numbers into my tracking spreadsheet.  The figures represent data for Q1, which now has 12 years’ worth of coverage.  With around 42% growth in the general storage hardware figures and 20% in external storage sales, the numbers… Read more »

Avoiding All-Flash Missing IOPS

We are living in a golden age of storage media, where new products come to market offering ever greater performance with lower latency than previous generations.  Today the hard drive and even early flash drives look positively archaic compared to modern NVMe drives built from 3D-XPoint, capable of delivering hundreds of thousands of IOPS and… Read more »

The Race towards End-to-End NVMe in the Data Centre

The next greatest thing in storage hardware is the move to NVMe.  This is occurring in two ways – conversion of internal designs within shared storage platforms to use NVMe at the “back-end”, and front-end (or host connectivity) using NVMe over Fabrics in some form.  Vendors are starting to use the term “end-to-end” NVMe as… Read more »

  • Are DataCore’s SPC Benchmarks Unfair?

    DataCore has been active over recent months with benchmarks based on their new SANsymphony Parallel Server offering.  The most recent of these claims 5.1 million SPC-1 IOPS at $0.08/SPC-1 IOPS and 0.32 millisecond response time.  Other vendors are crying foul on these results, claiming they don’t represent a true test because all of the data… Read more »

  • Docker for Mac & Windows – Changing the Developer Paradigm

    Over the years as a (part-time) programmer I’ve written a huge amount of code.  The specific languages I’ve used have included mainframe assembler, FORTRAN, Pascal, various flavours of BASIC, Visual Basic, Visual C++, C++ native, PHP, Perl, CLISTS, shell scripts of various types, Python, HTML, Java, Javascript and frameworks like Microsoft .NET.  With any of… Read more »

  • Docker & Storage – Solving The Problem of Data Persistence

    This week I’m in Seattle, the home of Starbucks, Boeing and Microsoft for DockerCon 2016.  Compared to the normal events I attend, this one promises to be a more “casual” affair, so I’m sporting polo shirts and vendor hoodies as my standard attire. One of the more interesting problems yet to be fully solved with… Read more »

  • SolidFire Introduces New “FlashForward” Purchasing Model

    If you’ve ever had to scope out and purchase enterprise storage, you’ll know what a nightmare it can be.  Vendors love to make the process as opaque as possible, with quotes that run into multiple pages and dozens of line items – including bezels and racks.  Consider also the issue of adding more hardware (e.g….

  • Torus – Because We Need Another Distributed Storage Software Solution

    Update: Accourding to the Github page for Torus, CoreOS ceased working on the project in February 2017.  Clearly it was obvious that developing a new storage platform is in fact hard and needs developers with knowledge and experience, rather than spare time on their hands. Last week the CoreOS project announced the release of Torus, a… Read more »
