What Happened to Storage Spaces Direct?

Can this article on The Register be true?  Has Microsoft removed Storage Spaces Direct from the latest Windows Server build? To be honest I’d initially not given this article much thought until I decided to have a look at the latest Windows Server build myself.  I was interested to find that I can’t actually download… Read more »

Block is Not the Solution for Persistent Container Storage

It appears we’re reaching a consensus that persistent storage is needed for containers.  Despite early resistance, with an assumption that containers and their data should be transient, the logic of data persistence is starting to take hold.  To be honest it simply makes sense. Yes, I could keep my data in sync between multiple nodes… Read more »

Can Violin Systems Successfully Rise from the Ashes of Violin Memory?

I recently met up with the CEO of Violin Systems, Ebrahim Abbasi, for a chat about the industry and the future of the company.  Those who knew Violin Memory will be familiar with this company as it is essentially the assets and IP of the failed Violin, acquired by the Soros Group and relaunched as… Read more »

That 100TB Drive Is Closer Than You Think

Another day goes by and we have another story about hard drive technology.  Yesterday, Western Digital held a media event (I wasn’t invited) to announce MAMR, the latest technology for improving hard drive density.  MAMR stands for Microwave Assisted Magnetic Recording and is a process to increase the stability of recording with very small grain… Read more »

Fixing the Problem of I/O With Parallel Computing – DataCore MaxParallel

The idea of improving the performance of applications through the use of parallel computing isn’t a new concept.  Look back 50 years and we can see that Amdahl’s Law shows how to predict the performance improvement that can be achieved by using multiple processors.  You can find details of Amdahl’s Law on Wikipedia, but essentially… Read more »

It’s Time for Hard Drives to Join Tape In The Archive Tier

This week we’ve seen the announcement of 14TB 3.5” hard drives from one vendor and 12TB from another. It’s hard to imagine the concept of 14TB in a single hard drive when ten years ago we were looking at only 1TB devices. However, these devices have a problem. The throughput and latency has remained relatively… Read more »

Azure Enterprise NFS by NetApp – Initial Thoughts

One of the big announcements coming out of NetApp Insight in Las Vegas is the release of Microsoft Azure Enterprise NFS Service using Data ONTAP technology.  The idea that a cloud hyperscaler could use a mainstream technology for storage instead of building their own is unique enough, but the more interesting scenario is the ability… Read more »

Scale Computing Debuts HC3 in Google Cloud Platform

Hyper-converged infrastructure is a great technology for running a range of mixed workloads.  With HCI how do you manage DR?  Typically the standard solution might be to run up another cluster in a separate data centre and run both 50% active/active or have one purely for standby.  What about running in the public cloud?  With… Read more »

Qumulo Releases QF2 – A Cross-Cloud Scale-Out File System

Over the last few weeks, I’ve talked a lot about data mobility and exactly how we should get data into the public cloud from on-premises locations.  You can find links to the posts at the end of this blog entry.  Much of what I’ve talked about revolves around moving data in a relatively static way,… Read more »

Measuring the Size of the Storage Market

Last week I posted a small comment on the latest IDC Storage Tracker figures.  The data shows ODM Direct as the largest category and the one with the most growth (73% year on year).  For some time I’ve wondered if the reporting of hardware really represents the state of the industry.  After all, it’s a… Read more »

  • 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 »

  • HPE 3PAR and Nimble – Finding that Differentiating Niche

    Update: I initially wrote this post and had it in draft for publication, however my views were changed by an announcement made today (see later in the post) I had some interesting feedback from one of my recent previous posts, in which I suggested that HPE might be planning to retire the 3PAR platform in… 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 »

  • 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? Tier 0 has come to represent the fastest of the fast, almost a specialist category of super fast storage.  The tier 0… 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. 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 »
