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?

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 »

  • Storage Field Day 7 – Initial Thoughts

    Storage Field Day 7 (11-13 March 2015) proved to be yet another impressive and thought provoking event, with lots of new ideas demonstrating that the storage industry is one of the most innovative and competitive sections of the technology landscape.  Over the next few weeks, I’ll deep dive into some of the more interesting presentations… Read more »

  • SanDisk Enters The Already Crowded All-Flash Market with InfiniFlash Product Line

    Earlier this month SanDisk announced InfiniFlash, their first entry into the All-Flash storage array (AFA) market.  I briefly blogged on the market impacts over on my company blog at Langton Blue; here I’m going to look a bit more into the specifics of the platform. First of all, let’s look at the detail here.  From a… Read more »

  • HDS Top with Latest SPC-1 All-Flash Benchmark

    Following hot on the heels of NetApp and their SPC-1 benchmark figures for the EF560 all-flash array, HDS have announced that the VSP G1000 has delivered the fastest benchmark figures to date, as highlighted in the graph shown here (borrowed from Hu Yoshida’s blog post on the news).  Links to the various SPC-1 results are… Read more »

  • IBM Storage “Rebrands”, But Only Partially

    In what I can only describe as a “remarkable” announcement, IBM has taken a number of their lacklustre storage products and rebranded them, using the new name of IBM Spectrum Storage.  The title of the press release implies some new software has been developed but the majority of the new spectrum platforms simply appear to be… 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 »

    The post mortem summary on Microsoft’s most recent Azure outage is available and online here.  The content makes for interesting reading.  To summarise, the outage occurred as a result of an unanticipated code error but was exacerbated by the accelerated rollout made by an employee who hadn’t adequately assessed the risks of pushing the change… 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 »
