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 »

  • AWS Provides Pricing via API

    At the beginning of December, AWS (Amazon Web Services) announced that pricing for their service offerings were now being made available via API (as well of course as via the web).  Customers and prospective customers can now query the cost of services such as EC2 and S3 through REST API calls, receiving the output either… Read more »

  • The Evolution of Storage Virtualisation

    Storage virtualisation is a technology that’s been around for many years and acts to abstract, in some form, the physical hardware from the LUN or volume the host/user sees.  The aim is to use this abstraction to reduce management overhead (for example with transparent migrations), to provide an ingest path (e.g. moving data from a… Read more »

  • The Ideal of Composable Infrastructure

    With the release of Synergy (see my recent post), HPE is moving towards a future that sees IT resources aggregated into applications deployed on-demand and in a totally automated fashion. In reality though, has HPE reached that stage with Synergy and can we put a definition on what Composable IT really means? If we look… Read more »

  • Composable IT – HPEs Next Big Thing

    At HPE Discover earlier this month HPE (or Hewlett Packard Enterprise as we now have to call them) announced their next evolution in managed infrastructure for which the company has coined the term Composable Infrastructure. The idea is to break down technology into its constituent parts and build or “compose” the pieces that allow for… Read more »

  • A New Paradigm for Computing

    The Christmas 2015 edition of Magpi magazine created a world’s first – an entire computer given away on the front of a magazine.  A free Raspberry Pi Zero is certainly a step up from a disk of software, or even the annoying AOL CDs that we know from years gone by.  This is an entire functional… Read more »

  • Do we need Storage QoS?

    I recently had a discussion with a vendor (who shall remain nameless) as to whether we really needed Quality of Service in shared storage arrays.  His thinking went as follows; if we have a storage array and network with sufficient bandwidth/IOPS, then why bother implementing QoS?  At first this seems like a reasonable assumption; if… Read more »

  • All Storage is Commodity

    Yesterday as part of the first A3 Tech Live event, I sat through a presentation from Memblaze, a vendor of NVMe and PCIe flash storage products.  Although the conversation was good natured and “robust”, I couldn’t help feeling that the company (like so many others in this market) have little to differentiate their products, other… Read more »

  • The Move to 3D-NAND for All-Flash Storage Vendors

    This week has seen two announcements from flash array vendors that are moving to support 3D-NAND technology in their products. On Tuesday Pure Storage announced that 3D TLC NAND would be supported in their FlashArray//m platform from 1Q2016. The new drives will increase capacity from around 30-40TB to 60TB per rack unit (depending on the… Read more »

  • Conflating Reliability and Endurance in SSDs

    Last week I sat through a presentation by Samsung on the evolution of their DRAM and flash business. One question raised by a journalist in the room related to the reliability of flash drives. The presenter proceeded to talk about the industry and how endurance means flash has a finite lifetime, one which now varies… Read more »
