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 »

  • Cloud Data Migration – Shipping Virtual Machines

    Previously we discussed the use of content migration tools to get data into public cloud services.  Another alternative is to ship entire virtual machines into the cloud, including the application and data. Why VMs? Why would it be more practical to ship an entire VM than just the data?  In some instances and with some… Read more »

  • QLC NAND – how real is it and what can we expect from the technology?

    Since NAND flash storage was first introduced into enterprise computing, we’ve seen a rapid explosion in the types and capabilities of flash products that can now be deployed in servers, HCI solutions and storage arrays.  QLC is the next evolution of cost reducing, space increasing flash technology.  What is it and what can we expect… Read more »

  • Flash Diversity: High Capacity Drives from Nimbus and Micron

    The desire to provide cheaper and greater capacity storage devices knows no bounds and has been a focus of the industry for the last 60 years.  Following on from Seagate’s 60TB “concept” flash drive, we now have two vendors selling 50TB OEM flash drives from Nimbus Data.  Let’s put that into context – the largest… Read more »

  • Scale Computing Moves Deeper Into the Enterprise With All-Flash HCI Nodes

  • Dude, Where’s My 100TB Hard Drive?

    It wasn’t that long ago we were being promised hard drives of unimaginable capacities.  I’m sure that at some stage triple digit numbers were being talked about.  However today we’re stuck with a “mere” 12TB of capacity per drive.  So what went wrong, or are we just being a little too hopeful? I did some… Read more »

  • Scality Introduces Zenko – A Multi-Cloud Data Controller

    When I met with Scality CEO Jerôme Lecat last week, he was at pains to ensure that Zenko – the company’s latest software product – wasn’t described as a storage gateway.  Jerôme sees gateways as protocol conversion devices, which as we will discuss is definitely not what Zenko is about.  So what is it exactly? … Read more »
