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 Renaissance of Data ONTAP

The genesis of NetApp, initially known as Network Appliance is ONTAP or Data ONTAP.  NetApp developed the ONTAP “storage operating system” to run on their original filer platforms.  It’s amazing to think the underlying technology from 1992 still drives the majority of their storage platforms today.  How has ONTAP managed to survive so long and… 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 »

  • 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 »

  • Review: AWS Storage Gateway

    Cloud Storage Gateways provide the ability to write data directly into a cloud service/storage provider, either via a physical or virtual onsite appliance.  There are many vendors in the marketplace today and some are making serious money, (as reported by Chris Mellor today in The Register).  Amazon Web Services, seen as a leader in Infrastructure… Read more »

  • Violin Memory acquires Gridiron Systems

    Yesterday, Violin announced that they have acquired Gridiron Systems, a vendor of cache acceleration hardware and software.  At the outset it may seem odd that an all-flash vendor would want to acquire a company offering acceleration for traditional arrays, however this could be a very smart deal indeed in a number of ways. Software is… Read more »

  • Storage QoS – How Hard Can It Be?

    Following up from yesterday’s post and the comments received, I thought it was worth considering how hard it would actually be to implement quality of service within a storage array. Almost all storage arrays available today (whether physical or virtual) work on the assumption that I/O should be delivered as fast as possible.  This is… Read more »

  • Storage QoS In The Cloud

    Last year I did some research and wrote up a couple of posts on Cloud Compute performance.  One feature that seems to get left out somewhat is storage I/O performance; the cloud offerings talk about capacity, but rarely reference performance. Recently, I reviewed the options available from the major providers and found two new storage performance offerings…. Read more »

  • Vendor Lock-in with Cloud Storage – Good or Bad?

    There have been two interesting and contrasting announcements covering cloud storage in the last couple of weeks.  The first was NetApp, who have announced “NetApp Private Storage for AWS”.  which seems to a proprietary way of replicating data into the AWS cloud.  The second comes from Nirvanix and Violin Memory; Violin have deployed their all-SSD… Read more »

  • The Evolution of Solid State Arrays

    In the first wave of solid-state storage arrays, we saw commodity style SSDs (solid state drives) being added to traditional storage appliances.  This solution provided an incremental benefit in performance over spinning hard drives, however the back-end technology in these arrays was developed up to 20 years ago and was purely focused around driving performance… Read more »
