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 »

Are We Suffering Logo Addiction Syndrome?

Remember when converged infrastructure came in?  We were told that packaging was the next best thing and doing things in separate towers of skills was bad.  Now it appears we’ve developed Logo Addiction and should be looking to build things from scratch again. The basis of this thesis is a presentation at Interop ITX by… Read more »

Validating HYCU Deployment By The Numbers

Vendors like to claim that their software is “1-click” or installable within 30 seconds.  In general these claims are pretty fatuous unless you’re either frequently deploying or looking to automate.  I’ve been spending a bit of time looking at a range of storage solutions that are fully software-defined and seeing how easy that deployment process… Read more »

Dell EMC to Offer Isilon on Google Cloud Platform

It’s Dell Technologies World this week in Las Vegas and the first announcement of interest is the future offering of the Isilon NAS platform on Google Cloud Platform.  The details of Isilon Cloud on GCP are scant, to say the least.  All I’ve found so far is this community post (link).  With little to go… Read more »

What are TBW and DWPD?

TBW is an acronym for  Terabytes Written and DWPD is an acronym for Device Writes Per Day.  Both are measures of the endurance of flash storage. Conflating Reliability and Endurance in SSDs What is the Technology Behind Samsung Z-NAND? Flash storage has a limit on the number of write (or specifically program/erase) cycles that can… Read more »

The Burden of Technical Debt

As the issues at TSB continue to unfold, I look on at an IT problem that will likely never be fully explained and eventually disappear into the archives as yet another “computer glitch”.  Why does it keep happening, what’s wrong with the industry and how can we do better next time? Experience Who am I… Read more »

NetApp embraces cloud for future business growth

Technology is a fickle business and surviving more than a few short years is hard to achieve.  The industry changes very quickly, as the next greatest thing consigns solutions and products to being legacy, even if they are still running many organisations’ core business.  Storage has evolved to be a major part of any IT… Read more »

Why HCI Data Protection is Different

When so many businesses are totally dependent on their digital information, data protection becomes a key requirement for every IT organisation.  The way in which we implement technology changes almost daily and this affects the choices on how we protect it.  Where 20 years ago the standard model for deployment was based on physical servers,… Read more »

  • Flash Tiering – HP 3PAR Adaptive Cache

    I recently completed a white paper for HPE on a new feature in the 3PAR StoreServ platform called Adaptive Cache.  In disk-based 3PAR systems, flash SSD devices can be used to augment the DRAM cache.  This acts like a second level of memory tiering by cascading cached pages to flash rather than simply flushing them… Read more »

  • Avere Systems Releases Virtual Edge Filer To Deliver Data to Compute

    It’s been a little over three years since I first was introduced to Avere Systems at what was SNW Europe (now Powering The Cloud) in Frankfurt.  At the time, the positioning on their FXT hardware platform was as an edge “caching” filer to allow core NAS assets to be extended to branch offices without sacrificing… Read more »

  • VSAN, VSA or Dedicated Array?

    I don’t normally write blog posts that follow up on other people’s discussions however having seen some of the tweets relating to Nigel’s blog post on VSA versus VSAN, I realised my comments on the subject would stretch to an entire post of their own.  So here it is. The discussion (although I haven’t listened… Read more »

The idea of spinning off parts… Read more »

  • EMC XtremIO Destructive Upgrade Demonstrates Architecture Matters

    News has emerged about a potential upgrade issue with the latest version of O/S code for the EMC XtremIO all-flash platform.  As discussed in this blog post, the upgrade to XIOS 3.0 is not simply disruptive but is destructive.  According to Chris Mellor’s post, the reason for the destructive nature of the upgrade is to… Read more »

  • VMworld 2014: VAIO – vSphere APIs for I/O Filtering

    One of the more interesting announcements at VMworld 2014 this year was a technology called VAIO or vSphere APIs for I/O Filtering.  This new feature was detailed in session TEX1492 (although I didn’t see it) and will allow 3rd party vendors to insert code in the form of a filter driver and deployed as a… Read more »

  • Why Have VVOLs Taken So Long to Deliver?

    Another VMworld has come and gone and still we haven’t seen the production deployment of VVOLs.  Just to recap, VVOLs are the evolution of the packaging of virtual machines that currently reside in data stores.  The main benefit is to be able to apply storage performance and availability policies to a VM object rather than… Read more »

  • Gartner Reveals Increasingly Irrelevant All Flash Array MQ

    Chris Mellor has posted a new ‘Register article that covers the inaugural Gartner Magic Quadrant for Solid State (or all-flash) Arrays.  It’s an interesting read, with EMC and Pure Storage topping the polls and IBM not far behind.  However as the use of flash within the enterprise has increased, the idea of a magic quadrant… Read more »
