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 »

Micron ushers in the era of QLC SSDs

To date we’ve only seen QLC NAND storage in the consumer SD card format, however, that’s set to change as Micron announces the first QLC SATA SSD for the data centre.  The Micron 5210 ION SSD will deliver up to 7.68TB of capacity in a standard 2.5″, 7mm form factor.  But there’s a catch –… Read more »

Conflating Data Protection and Data Mobility

Sitting on the sidelines, I’ve been watching some of the traffic and communications coming from VeeamON this week.  Chris Mellor just posted a quick article summing up the ambitions of Veeam as a company.  It struck me that we continue to conflate the idea of data protection and data mobility.  To me, these are two… Read more »

NetApp Extends Cloud Volumes to GCP

Following their introduction on Microsoft Azure last year, native NetApp Cloud Volumes are to be made available through Google Cloud Platform.  NetApp now offers Cloud Volumes in some form on the three major (Western) cloud providers, AWS, Azure and GCP.  How should we view this, especially in respect of how cloud services are evolving? Maturity… Read more »

PowerMax, VMAX, XtremIO – the Agony of Choice

Last week Dell EMC announced the next generation of the long-running Symmetrix platform with the release of PowerMax.  This all-NVMe array apparently isn’t a replacement for VMAX (or XtremIO).  However it is yet another decision point in customer choice for all-flash from Dell EMC.  Does the company need another all-flash array or is this just… Read more »

  • Iaas Series: Amazon S3 Version Objects Lifecycle Management

    S3, or Simple Storage Service is Amazon’s high capacity, high resiliency object store.  The company recently announced a new feature, which allows versioned objects (those objects where multiple versions are retained for historical archive purposes) in S3 to be managed with lifecycle rules that either move data to AWS Glacier or assign a time period… 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 »

  • What Does The Future Hold For Pure Storage?

    Timing is everything in this game and following my last post (by mere minutes) on Pure Storage’s new FlashArray announcements, Chris Mellor at The Register wrote an article discussing Pure’s future evolution. The inevitable comparison is made with NetApp and their “single” platform of 20 years, namely Data ONTAP.  Forgive me for sounding like a… Read more »

  • Pure Storage Release 4th Generation of FlashArray Hardware

  • 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 »

  • Project Liberty – A Brave Step For EMC?

    In the run-up to EMC World next week, EMC has released information about something they are calling “Project Liberty”, which appears to be a virtual appliance based on VNX.  Is this a serious attempt to deliver products for the ethereal Software Defined Data Centre and what risk does this pose to EMC’s traditional storage business?… Read more »
