rook.io – an attempt at Flocker 2.0

At the end of 2016 ClusterHQ, the developers of Flocker decided to shut down the project with a rather blunt blog post (link).  Rather than take additional funding, CEO Mark Davis (and presumably the board) decided to shut the company down on the assumption that it wasn’t clear where revenue would come from. Based on… Read more »

What Next for the new Tier 0 Storage?

As flash storage moves to mainstream adoption, a new breed of products are set to become the new tier 0 storage.  However with the demise of DSSD, is the market set to falter?

Learning from The Instapaper Outage

Instapaper (the SaaS-based solution for keeping track of bookmarks and interesting websites) suffered a catastrophic outage to their service last month.  I’ve only just got round to reading the port-mortem account of the incident and it doesn’t make pretty reading.  First of all, it’s worth saying that we’ve all been there and experienced that awful… 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 »

  • 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 »
