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 »

  • Podcast #1 – Serverless and Containers 101

    In what might become a more regular series, I spent some time yesterday chatting with Christian Beedgen, CTO and co-founder of Sumo Logic and Alex Chircop CTO and co-founder at StorageOS.  We recorded the conversation as a live podcast, which is an introduction to the concepts of containers and serverless computing.  The aim here was… Read more »

  • Rent Out Your Spare Disk Space With Storj

    As I think I’ve mentioned a few times on this and other blogs before, around the late 1990s I looked at the practicality of creating a distributed storage platform that would act as a backup for personal storage.  As the amount of data being personally stored was increasing (via photos, video and other content), being… Read more »

  • The Risk of Shared Service Level Agreements

    Wikipedia defines a service-level agreement (SLA) as an “official commitment that prevails between a service provider and a client.  Particular aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user”.  In my experience, I’ve always seen an SLA as a contractual agreement for services, with penalties… Read more »

  • Storage Market Shows Growth – But Not In External Arrays

    It’s been about six months since I last looked at the IDC quarterly storage market figures.  The latest data for 4Q2017 has just been released, so it’s time for an update.  I’ve also found some missing data, which means I can show the annual growth figures for both 2016 and 2017, providing 7 years of… Read more »

  • ScaleIO Becomes Software Defined on Hardware

    Chris Mellor posted an article on The Register yesterday that follows up on the recent Dell EMC re-organisation.  ScaleIO, originally a pure SDS (software-defined storage) play will now only be sold in conjunction with Dell hardware (in VxRack FLEX), as it moves into the server business unit.  At a time when vendors are starting to… Read more »

  • Modern Storage Architectures: Datrium

    This is one of a series of posts that will cover new storage architectures for the enterprise data centre and form part of an Architecting IT white paper later this year. Storage platforms for primary workloads have generally fallen into a few standard categories, such as dual-controller or scale-out.  With spinning media, the overhead of… Read more »

  • Dropbox Files for IPO

    It’s arrived.  Dropbox, the ubiquitous file-sharing platform, has finally submitted a rather light S-1, indicating an Initial Public Offering is on the way.  From the various reports written so far, it’s likely the company is intending to raise around $500m. Subsidies The first thing that leaps out at me when looking into the announcement is… Read more »

  • Dell Terminates {code}

    Dell Inc has apparently pulled the funding for the {code} team, a set of projects to develop open source software within the company.  As reported by The New Stack, the team is being wound up, with the work allegedly being picked up other teams.  However, blogs like this from Kendrick Coleman indicate that perhaps the… Read more »

  • Samsung 30TB SSD – The New Normal

    Samsung has just announced 30.72TB in a single SAS SSD.  Let’s just think what that means for a moment.  That’s around 6,500 DVDs or 1,200 Blu-Ray disks, depending on how you do your maths.  It’s an amazing achievement.  In that form factor, 30TB in a 2.5″ drive is 6x the largest HDD available and around… Read more »
