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 »

  • Goodbye Virsto

    With effect from 1st January 2014, VMware have announced that their Virsto acquisition is end of life and no longer available for purchase.  The brief statement released by the company indicates that support will continue until September 2015. I first looked at Virsto in 2011 with a brief review in a post that compared the… Read more »

  • 2014 – The Year of Storage Virtualisation

    Earlier this week I was reading an article in the UK’s Computing magazine, which listed research on key priorities for businesses over the next three years.  The top three items for research were listed as Storage Virtualisation, Desktop Virtualisation and solid state drives (SSDs).  I was interested that 56% of respondents said they were looking… Read more »

  • A Ten Year Flash Array? No Thanks!

    George Crump makes some interesting comments in his recent article on whether today’s breed of all-flash storage arrays could survive for 10 years in the data centre.  Whilst the logic of his comments make sense, I think there’s little desire to be using today’s all flash devices in 10 years’ time. There’s no reason to… Read more »

  • Nimble Storage Reaches Successful IPO – What Next?

    Disclaimer – this post does not constitute financial advice in any way and all information provided is purely for illustrative purposes. Last Friday, which was the 13th and clearly not unlucky for some, Nimble Storage Inc floated on the New York Stock Exchange at an opening price of $21.  The shares did well, closing at… Read more »

  • The Maturing of Flash Storage

    It’s interesting reading the comments that we’re added to my post of last week, discussing the summary of all flash arrays, initially started by Vaughn Stewart and continued by HP storage guy Calvin Zito. Unsurprisingly, most of the negativity came from EMC and their resellers, who are defending a late entrance into the market.  They… Read more »

  • XtremIO: What You Need to Know (Updated)

    With much anticipation, EMC has finally gone GA on their all-flash array, XtremIO, based on the former company of the same name they acquired in May 2012.  The eighteen months that have elapsed since then has seen the rise of an number of competitors and a lot of rumour, discussion and teaser presentations from EMC… Read more »

  • Avere Systems Embraces Cloud with Cloud NAS

    Cloud storage is a popular subject these days, with some good and some bad examples out there.  The appeal is obvious – data needs to be retained somewhere, whether it is of the primary, backup or archive flavour.  Being able to do that at low cost (especially when a large percentage of that data is… Read more »

  • 6TB HGST Helium Drive Continues Move to Two-Tier Storage

    Over the years, hard disk drives have steadily increased their speeds, peaking at 15,000 RPM, with only a fleeting attempt by Western Digital to push the boundaries up to 20K.  As we know, at that point solid-state drives became more viable than faster HDDs and manufacturers have reined back their aspirations.  Recently we’ve seen more… Read more »

  • NFS Vendor Benchmarks – Caveat Emptor

    This week we’ve seen an update on NFS benchmarks with Hitachi announcing their latest results (via Hu’s blog) using HUS File and FMDs (Flash Module Drives).  Of course Hitachi wouldn’t be announcing if they hadn’t beaten EMC with the figures; no-one releases data that makes them look worse, after all.  But what are the data… Read more »
