Pure Accelerate: FlashArray Gets Synchronous Replication

Synchronous replication is a key feature that many enterprises depend on for data protection as it offers the ability to ensure data is 100% copied to a remote site in the event of a disaster.  On flash storage, sync replication may seem a little at odds with the idea of providing high performance, but the… Read more »

Has Dell EMC Redesigned XDP on XtremIO?

Earlier this month Dell EMC announced XtremIO X2, the next generation hardware platform of their once flagship all-flash storage offering.  With the new systems, storage capacity per node has been increased from 25 to 72 drives.  The numbers quoted for initial deployments and upgrades seems to counter the original design of data protection on XtremIO,… Read more »

Recent Cyber Attacks Show a Massive Misunderstanding About Technology

The cyber attack affecting a large part of the UK NHS (and also more globally) has been widely reported over the weekend.  As usual, I find myself screaming at the TV, due to the misdirection being put forward by the media as to the causes and solution to the problem.  This morning I read an… Read more »

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 »

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 »

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.

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 »

  • 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 »

  • 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 »

  • VSAN, VSA or Dedicated Array?

    I don’t normally write blog posts that follow up on other people’s discussions however having seen some of the tweets relating to Nigel’s blog post on VSA versus VSAN, I realised my comments on the subject would stretch to an entire post of their own.  So here it is.
