Data Mobility – Caching Technologies

This is one of a series of posts looking at data mobility for the hybrid cloud. You can find a link to all of the published articles as they become available here.  (link). Caching is not a new technology.  In fact, it’s been used as a technique to cost-effectively accelerate I/O performance since computers were… Read more »

Object Storage Critical Capabilities #3 – Searching, Indexing and Metadata

This is the third in a series of posts covering object storage requirements.  Other posts in this series can be found at Object Storage Capabilities Series. Object stores are intended to store large volumes of data.  Capacities are usually measured in hundreds of terabytes or petabytes rather than smaller units.  As a result, an object… Read more »

Public Cloud is Still Hardware Focused

Microsoft Azure has recently announced that the latest AMD EPYC processors will be available on a range of Azure compute instances.  The new instances are storage optimised, meaning they are aimed at high I/O workloads.  This isn’t surprising because the EPYC processors have typically 2-3 times more bandwidth capability than their Intel Xeon counterparts.  With… Read more »

Technology Choices for Data Mobility in Hybrid Cloud

Over the past 12-18 months, I’ve done a lot of work looking at options for getting existing data into the public cloud.  You may have noticed that I’ve talked a lot about the subject over this period.  There are links at the end of this post to that content.  However, I thought it might be… Read more »

The Impact of Meltdown/Spectre for Storage & HCI

Edit: Chris Mellor at The Register has some additional comment from vendors, including Scale Computing. (link).  Further Register emails (link) point to significant slow downs in workload.  And here’s another post regarding the need (or not) to patch storage appliances. Unless you’ve been 100% disconnected from technology (and the Internet) over the last few days,… Read more »

Seagate Pre-announces Multi-Actuator Drives

When your technology is based on mechanical motion, it’s inevitable that at some point the laws of physics will get in the way.  This has been a problem for hard disk drives for some time.  Spin speeds never exceeded 15K RPM except in some test drives.  As a result, throughput has been limited by this… Read more »

Survey – Give us Your Views of 2017 and Thoughts for 2018

As we near the end of 2017, it’s a great time to reflect on the year and what’s been achieved.  As part of 2018 planning, we’d like to get your views on what you would like to see talked about in 2018. We ask that you complete a very short survey – so short it’s… Read more »

  • HPE Brings Nimble Skynet to 3PAR Arrays

    Who doesn’t like the idea of having six 9’s of uptime for their storage?  Availability is a major consideration for any storage, public or private.  Of course, having great availability isn’t the only measure of storage quality.  We also value performance, low latency and consistency.  But making storage behave in a predictable manner isn’t always… Read more »

  • Accelerating Workloads with NetApp Plexistor

    I hadn’t realised that NetApp acquired Plexistor earlier this year.  Depending on which site you look at, the acquisition was a pretty cheap $20m or $32m, based on an A-round investment of around $4.5m in September 2014.  NetApp demonstrated application acceleration using the Plexistor technology at Insight in Berlin last week (see the day 2… Read more »

  • VMAX – The Mainframe of Storage

    This post title may sound a little controversial, but that’s far from my intention.  Anyone who knows me will be aware that I started out in the mainframe era.  I like the mainframe’s reliability and maturity of features, many of which took a long time to arrive in today’s IT world.  However, the mainframe is… Read more »

  • Storage Field Day 14 Preview: E8 Storage

    I initially held off reviewing E8 Storage as we had a podcast scheduled with CEO Zivan Ori, which went live last Friday.  Rather than make assumptions about the technology, I wanted to ensure I was giving some credit to the architecture.  I’m glad I did wait because there were one or two fundamentals I hadn’t… Read more »

  • Should I Be Backing Up Containers?

    The initial answer to the question, “should I be backing up containers”, would appear to be no.  On the face of it, a container is meant to be a temporary instance of an application component and so not long-lived enough to need backing up.  But digging deeper, there is a need for backup – depending… Read more »

  • With LTO-8, Tape Capacities Show No Sign of Slowing Down

    On 17 October 2017, the LTO consortium announced the availability of LTO-8, the next generation of LTO tape technology.  LTO is run by three technology provider companies (TPCs), namely HPE, IBM, and Quantum.  Since the first products were released in 2000, LTO media has increased from 100GB capacity with LTO-1 to 12TB on LTO-8.  The… Read more »

  • OK, Google – Where are my Docs?

    Hallowe’en turned out to be a real fright for some Google Docs users yesterday as access to content was blocked due to a buggy code push.  The result was that certain content was flagged to have broken Google’s Terms and Conditions.  As widely reported, for some users this could have been a real issue, had… Read more »
