Software Defining Your Storage

There is a lot of talk in the technology industry of “software defining”, the idea that elements of our technology stack, traditionally based on a hardware appliance can be abstracted from it and made available as a software-only appliance that can be installed on any hardware.  But why? Wouldn’t you rather your key assets were… Read more »

The need for self-describing secondary data

As primary data becomes ever more portable, we need to ensure that our backups have the same levels of flexibility to be moved, stored and used wherever we need them.  Why is this important, and what features should we look out for? Data Protection in a Multi-Cloud World The Need for APIs in Storage and… Read more »

Can the WekaIO Matrix file system be faster than DAS?

There’s a standard adage in the storage industry.  If you want lower latency and better performance, then move storage closer to the processor.  Typically, this means implementing DAS – Direct Attached Storage – and eliminating a shared network.  So how can WekaIO Matrix, a distributed scale-out file system claim to be better than DAS yet… Read more »

Pure Storage ObjectEngine for Flash-based Backup

Back in August 2018, Pure Storage announced the acquisition of StorReduce, a start-up company with a nifty data de-duplication engine.  That technology has been put to good use and now appears in ObjectEngine, a backup-to-flash data protection solution. StorReduce As previously highlighted, I looked at StorReduce in 2015 and was quite positive about the technology. … Read more »

VAST Data launches with new scale-out storage platform

“Build it and they will come” they say, or at least, something similar.  So, Vast Data has built a new scale-out storage platform and hopes that customers will flock to adopt it.  It’s 2019 – do we need another scale-out storage architecture? Amelioration I’m sure when we reflect on products that have gone before, we… Read more »

Pure Storage announces NVMe-oF support for FlashArray

Pure Storage recently announced support for NVMe over Fabrics on FlashArray.  The technology is implemented by an upgrade to Purity (the platform O/S) and installation of RDMA-capable Ethernet NICs.  Pure has chosen to go with Ethernet as the first NVMe fabric offering, while other vendors have chosen the Fibre Channel route.  How has this choice… Read more »

Exploiting secondary data with NDAS from NetApp

Occasionally a technology leaps out at you, not for the current capabilities, but for potential future value.  That’s a feeling I had when I heard about NDAS or NetApp Data Availability Services.  At first glance, NDAS looks like nothing more than a simple backup-to-cloud tool, but dig into how the data is managed and you… Read more »

Podcast #3 – Chris & Matt review the SFD18 presenters

Here’s a little extra podcast Matt Leib and I recorded this afternoon in preparation for Storage Field Day 18.  You can tell this wasn’t recorded in a studio, but actually Matt’s hotel room!  Matt preps coffee in his mini-Nespresso device while we discuss each of the presenting vendors. The discussion is ad-hoc, off the cuff… Read more »

The Need for APIs in Storage and Data Protection

The idea of programmatically managing infrastructure provides capabilities to scale, manage and control technology much more effectively than can be achieved through manual methods.  But the use of APIs means so much more than simply providing an interface that can be automated.  APIs introduce greater efficiency and accountability into storage platforms.  We look at how… Read more »

MAX Data: Optimising Application Performance with SCM

As the slowest part of the computing architecture, persistent storage is in a constant battle to improve performance.  That goal has moved from being focused on throughput a few decades ago to one of reducing latency as low as possible.  To that end, NVM Express and NVMe over Fabrics have become an area of focus… Read more »

  • The Psychology of Pricing

    It’s been another interesting week in IT.  Following on from recent rumours, Nirvanix have finally publicly announced they are closing down, replacing their website with a single holding page directing customers to IBM.  Yesterday, Violin Memory released their shares to the public and floated on the New York Stock Exchange.  Unfortunately there wasn’t a lot… Read more »

  • What EMC Should Have Done With VNX

    My last post discussed the issues with EMC’s strategy around the marketing of their new VNX platform.  Some people will think picking holes in a vendor’s strategy is easy writing, so for those of that persuasion, I’ve taken the time to look at EMC’s portfolio and express an opinion on where EMC should go next….

  • Performance Tier or Capacity Tier? – No It’s the Working Set

    There have been a couple of articles on The Register over the last couple of days talking about EMC CTO John Roese and his use of the terms “Capacity Tier” for VMAX storage and “Performance Tier” for their flash solutions.  Sadly this shows EMCs CTO has an outdated view of the industry, is perpetuating old-school… Read more »

  • ScaleIO, EMC’s New Baby

    Keeping up the theme of innovation in storage (yes, it exists, you just have to look), earlier this week I had a chat to one of the UK folks at ScaleIO, the startup now acquired by EMC.

    In a news announcement yesterday, STEC Inc, makers of solid state flash drives (SSDs) announced a “merger” with (i.e. was acquired by) Western Digital, one of the leading hard disk drive manufacturers.  It’s a spectacular fall for a company that at one stage had a share price of over $41/share in September 2009.  However an… Read more »

  • HP 3PAR 7450 All Flash Array

    I mentioned in a previous post that I would delve a little deeper into what HP have done to optimise performance on the new 3PAR 7450.  I was lucky to be able to catch up at the 3Par booth with Priyadarshi Prasad, who works in marketing for HP 3PAR.  We took some time to talk… Read more »

  • ViPR – Frankenstorage Revisited

    Cast your minds back to 2009.  At that time, Chuck Hollis wrote a blog post that quoted the following definition: “Frankenstorage appears to be a new twist on [the Frankenstein] idea — storage arrays, assembled from various parts from multiple vendors, brought to life by the magic of powerpoints and press releases.” The crux of the… Read more »

  • Defining Software Defined Storage

    The term Software Defined Storage has generally accepted within IT as a process for delivering storage without the lock-in of hardware from the vendor.  How has our understanding of the term evolved over recent years? It’s easy to use the examples of server virtualisation and networking as reasons why thinking of storage virtualisation for SDS… Read more »
