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 »

  • 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 »

  • Enterprise Computing – Death of Tiering?

    I’m not the first to post on the subject of Netapp’s President and CEO Tom Georgens commenting during their latest earnings call on the apparent death of tiering as we know it today. In Netapp’s view, there will be no tiering of storage in the future.  Instead we will be using SATA drives for our… Read more »

  • Enterprise Computing: Thin Provisioning and The Cookie Monster!

    The Gestalt IT Field Day was a great success in bringing together a mixture of delegates from varying discplines. Following the presentations from 3Par and Symantec, there was heated debate about the implementation of Thin Provisioning and the ability to reclaim released storage resources. This post covers the basic concepts of Thin Provisioning and more… Read more »

  • Enterprise Computing: Why Thin Provisioning Is Not The Holy Grail for Utilisation

    Thin Provisioning (Dynamic Provisioning, Virtual Provisioning, or whatever you prefer to call it) is being heavily touted as a method of reducing storage costs.  Whilst at the outset it seems to provide some significant storage savings, it isn’t the answer for all our storage ills. What is it Thin Provisioning (TP) is a way of reducing… Read more »

  • Whatever Happened to Hybrid Drives?

    Over 18 months ago, I discussed in a post (here) the Hybrid Storage Alliance who were looking to increase the performance of hard drives by adding large amounts of flash to each device. But where are they now? A quick check on their website shows precious little information. In fact what’s on offer seems to… Read more »

  • Invista

    There’s been a few references to Invista over the last couple of weeks, notably from Barry discussing the “stealth announcement”. I commented on Barry’s blog that I felt Invista had been a failure, due to the number of sales. I’m not quite sure why this is so, as I think that virtualisation in the fabric… Read more »
