The Shifting Storage Investment Paradigm

The standard evolution for startup vendors in the storage market has been to create a product, build a customer base and wait to be acquired or float the company in an IPO.  Some companies have been more successful than others.  XtremIO for example was acquired very early – great for the VCs that put up… Read more »

Is AWS Moving to Private Cloud with Snowball Edge and EC2?

At a recent AWS Summit in New York, Amazon Web Services announced the availability of EC2 on Snowball Edge devices.  Does this move represent a challenge for private cloud and could it be the start of a hybrid strategy for the company? Snowball Edge In case you’ve not seen it before, the Snowball is a… Read more »

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 »

  • EMC Releases All Flash VNX

    As the vendor who introduced flash drives into traditional arrays some 2+ years ago, we shouldn’t be surprised that EMC has released an all-flash version of its mid-range array, the VNX.  The new device, codenamed VNX5500-F can support up to 250 200GB drives for a maximum all-flash capacity of 50TB.  EMC don’t say, but assuming… Read more »

  • Solid State Arrays: SolidFire

    One of the attendees at TFD#8 was SolidFire Inc, another startup company focusing on selling entirely solid-state disk arrays.  As you’d expect, they have their own niche and part of the market they are targeting with their all-flash drive product.  So how do they compare to the competition and what’s their “unique selling point” compared… Read more »

  • Solid State Arrays: Pure Storage Inc

    A clear focus of the recent Tech Field Day #8 event was the use of flash storage (or SSDs) for storage arrays or within hybrid solutions.  Pure Storage offers an all flash storage array, which they say can be delivered at the same cost or less than traditional solutions.  It’s a big claim, bearing in… Read more »

  • Who Will Be The First Solid State Array Vendor To Be Acquired?

    Unless you’ve been living under a rock for the last two years, you can’t have failed to notice that solid state storage is here and is here in a big way.  Two weeks ago at TFD#8, we had presentations from two all-flash array startups, Pure Storage and SolidFire.  I’ll have more specifics on these companies… Read more »

  • Why Does Microsoft Hyper-V Not Support NFS?

    I recently wrote an article covering storage for virtualisation and was surprised to find out that Microsoft does not support the use of NFS shares with Hyper-V.  At first I thought perhaps I was doing something wrong and that my configuration was in error.  But after a lot of lab testing and eventually finding some… Read more »

  • So Your AWS-based Application is Down? Don’t Blame Amazon

    After a busy day in London I returned home to read the news of issues in one of Amazon’s US data centre locations causing problems with EC2 and database (RDS) instances.  It seems the services of many Internet companies were affected including Reddit, Quora, Hootsuite and FourSquare,  Is it fair that Amazon should shoulder the… Read more »

  • You can’t trust what you read on the Internet – Unless it’s EMC

    Seems like Chris Mellor has struck a raw nerve with EMC and in particular Chad Sakac over this article he wrote for The Register.  Unfortunately Chad’s response makes him appear more like a spoilt child than a marketing professional who’s prepared to take the rough with the smooth in IT marketing.  Of course this isn’t… Read more »

  • NetApp: The Inflexibility of Flexvols

    I’ve just been reading up on Data ONTAP 8.0 as part of some ongoing work I’m doing.  You may be aware that version 8.0 of the filer operating system brings two major features; 64-bit support and the (sort of) integration of the Spinnaker code to create the multi-node version of ONTAP (called cluster mode). The… Read more »

  • Enterprise Computing: The Slow Demise of The Hard Drive

    Yesterday Nimbus Data Systems announced the release of their S-Class storage array.  What’s different about this storage device is that it uses purely NAND memory rather than traditional spinning disk.  With it’s arrival, we’re seeing another nail in the coffin of the traditional hard drive. OK, so the S-Class isn’t going to replace hard drives… Read more »
