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 »

  • 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 »

  • Change Control in Cloud Services

    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 »

  • 2014 in Review

    As we approach the start of a new working year, it’s time to take the almost traditional and obligatory review of the year hence.  So, what made the news and how does that provide us insight on the year to come? Big Trends There were certainly some interesting developments in storage and the wider IT… Read more »

  • Understanding IDC’s Flash Sales Figures

    IDC recently produced a report showing the sales and shipment of all-flash and hybrid storage arrays.  The report shows EMC as top dog and not surprisingly, EMC have provided a free downloadable excerpt, available here.  I always like to dig into numbers into a little more detail as you can start to uncover interesting trends… Read more »

  • NetApp Integrated EVO: RAIL – A Triumph of Marketing Over Common Sense

    I suspect I wasn’t the only one last week who was scratching his head at the latest idea from NetApp which sees them offering a VMware EVO: RAIL solution that incorporates Data ONTAP filer technology.  In case that last statement is unclear to you, yes, NetApp are suggesting that EVO: RAIL, the solution that uses… Read more »

  • HDS & 3PAR Top In Gartner’s General Purpose High End Arrays

    It’s HP Discover week in Barcelona and so an appropriate time to talk about Gartner’s recent Critical Capabilities for General-Purpose, High-End Storage Arrays report.  Chris Mellor covered the details in a recent article, which included a chart of the top players.  Hitachi (through both the HDS and HP models) comes out top with their VSP… Read more »
