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 »

  • Primary Storage De-duplication: Only for SSD Arrays?

    I recently wrote an article for TechTarget that looked at the implementations of data de-duplication in primary storage arrays.  One of the things that stood out for me was the lack of de-duplication support in traditional (and some might say legacy) storage arrays. The cynical amongst us would say that the big 5 storage vendors… Read more »

  • EMC Enters The Market With “Me Too” Flash Products

    Yesterday EMC finally revealed the details on their not-so-secret Lightning and Thunder flash projects.  Fortunately this launch event didn’t include cramming small people into minis or firing Chad Sakac out of a cannon, but was more focused on the market and products EMC are bringing to it.  There was also a large amount of Twitter… Read more »

  • What to Watch in Storage for 2012

    As I write this post, 2012 is already 6.3% completed.  So, for the remaining 93.7% of the year, what can we expect the storage themes to be?  What will companies be focused on and what can we expect from the vendors? Data Reduction The recent flooding in Thailand has had everyone on high alert about… Read more »

  • Emulex – Evolution of the HBA

    At SNW Europe this week I took some time to talk to Emulex about their OneCommand product.  It’s been upgraded to version 2.0, which will be the subject of a post for another day, once I’ve had a chance to install and review it. I also discussed the core of Emulex’s business, namely HBAs (Host… Read more »

  • EMC Releases All Flash VNX

    As the vendor who introduced flash drives into traditional arrays some 2+ years ago, we shouldn’t be surprised that EMC has released an all-flash version of its mid-range array, the VNX.  The new device, codenamed VNX5500-F can support up to 250 200GB drives for a maximum all-flash capacity of 50TB.  EMC don’t say, but assuming… Read more »

  • Solid State Arrays: SolidFire

    One of the attendees at TFD#8 was SolidFire Inc, another startup company focusing on selling entirely solid-state disk arrays.  As you’d expect, they have their own niche and part of the market they are targeting with their all-flash drive product.  So how do they compare to the competition and what’s their “unique selling point” compared… Read more »

  • Solid State Arrays: Pure Storage Inc

    A clear focus of the recent Tech Field Day #8 event was the use of flash storage (or SSDs) for storage arrays or within hybrid solutions.  Pure Storage offers an all flash storage array, which they say can be delivered at the same cost or less than traditional solutions.  It’s a big claim, bearing in… Read more »

  • Who Will Be The First Solid State Array Vendor To Be Acquired?

    Unless you’ve been living under a rock for the last two years, you can’t have failed to notice that solid state storage is here and is here in a big way.  Two weeks ago at TFD#8, we had presentations from two all-flash array startups, Pure Storage and SolidFire.  I’ll have more specifics on these companies… Read more »

  • Why Does Microsoft Hyper-V Not Support NFS?

    I recently wrote an article covering storage for virtualisation and was surprised to find out that Microsoft does not support the use of NFS shares with Hyper-V.  At first I thought perhaps I was doing something wrong and that my configuration was in error.  But after a lot of lab testing and eventually finding some… Read more »
