Nimble, HPE and 20-Year Old Architectures

This week, HPE offered to acquire Nimble Storage for around $1.09 billion, plus another $200 million in share options.  Nimble sells all-flash and hybrid storage solutions, with a lot of intellectual property focused around storage analytics in the form of their “Infosight” SaaS platform. Commentators are seeing this as a good deal for both Nimble and… Read more »

Should We Worry About The S3 Outage?

Last week, Amazon Web Service’s S3 (Simple Storage Service) suffered what was termed “high error rates” and essentially became unusable for a number of hours to users in the US-East-1 (Virginia) region.  There have been a lot of stories circulating talking about the number of SaaS-based applications that were affected, with people being quick to question the… Read more »

Google Spanner – fixing the problem of distributed SQL databases

I’ve been messing about with databases for a long time.  I say “messing about” because I’ve never been a DBA, but as a systems programmer and storage administrator, I’ve been on the periphery of the application layer and of course I’ve deployed many personal databases.  I was intrigued to read about the new global distributed… Read more »

Nine Critical Features for Object Stores

Object storage is a relatively new market segment that has continued to grow steadily and is starting to find more reasons for adoption.  For the uninitiated, object stores are used to hold large volumes of unstructured data, where each “object” is essentially a file with no specific format (also called a binary file).  Object stores… Read more »

Building Data Storage With Containers

Note: Updated on 18 January 2017 to include OpenEBS. There’s an almost religious divide between those who see containers as entirely stateless objects and others taking a more pragmatic approach that says state and containers is an inevitable thing.  In the stateless model, data is assumed to be replicated and protected by many container instances,… Read more »

HPE Demos 3PAR with Intel Optane (3D-XPoint)

There’s been a lot of coverage and potential hype around the impending release of Intel and Micron’s 3D-XPoint persistent storage technology.  Now it seems we have a good example of how Optane (as Intel are branding it) could be deployed into existing storage platforms.  During HPE Discover London (December 2016), the 3PAR team ran a demo… Read more »

AWS Getting Serious About Enterprise On-Prem with Dockerised Linux AMI

AWS just announced the availability of an on-premises version of their Linux AMI, delivered as a Docker image (link).  This may seem an innocent and rather subdued announcement, but don’t forget that we also recently had the release of the AWS Server Migration Service (link) at the end of October.  AWS and VMware just became… Read more »

Focus on High Performance NAS

Block-based storage (and particularly that based on Fibre Channel) has always been the favoured child when it comes to vendors talking about their products and solutions.  All of the high-end performing devices tend (but not exclusively) to be block-based.  However we’re seeing an increased focus on high performance NAS platforms, especially those with scale-out capabilities….

Peak VMware

Updated: AWS is pushing on with getting workload into the cloud directly too – see the new AWS Server Migration Service (link) Last week, VMware announced a new service called VMware Cloud on AWS (abbreviated  by some people to VMC).  I’ve been taking a little time to digest the news and views of others before… Read more »

SNIA has high hopes for Swordfish

Probably the most annoying and frustrating part of being a storage manager in the 1990s was the lack of decent management and automation tools.  Each storage vendor had some good and some bad software for managing their arrays.  EMC’s Symmetrix/DMX/VMAX range, for example, had a great and well thought out CLI management tool; Solutions Enabler….

  • Why VSAN and VVOLs are Not Software Defined

    Every so often another attempt is made by the vendor community to put a definition to what we call “software defined storage” or SDS.  The current discussion is on VMware Virtual SAN (VSAN) and VVOLs, software features focused on storage within the vSphere hypervisor ecosystem. This seems like a good opportunity for me to review what… Read more »

    There’s been a bit of conversation recently on the intention of EMC to put drivers for their ScaleIO platform into the VMware ESXi hypervisor kernel.  The discussion was triggered by an article published in LeMagIT on 25 November 2014 by Christophe Bardy and subsequently picked up by The Register.  It implied that VMware and EMC were… Read more »

  • What Next for Storage in 2015?

    Sometimes it’s hard to believe that there’s anything more to achieve in data storage.  Surely things are pretty much complete; we have the ability to store vast quantities of data reliably and each year the per unit cost of storage continues to decline.  So as 2015 rolls in, is there anything left to achieve?  What… Read more »
