Kaminario Goes Software-Defined

Kaminario recently announced that the company is moving to a software-based business model.  Rather than build and support storage arrays, Kaminario will partner with Tech Data for logistics and essentially focus on the software part of their offering.  Is this an admission of defeat or a sign of the times? A Hardware History Kaminario has… Read more »

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 »

Do you have feedback on what you would like to see in 2018?  Please take less than two minutes to answer our really quick 5 question survey! – link A quick look at the adoption of technology over the last 60 years shows us that no one vendor, technology or concept becomes 100% dominant.  Back… 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 »

  • VMware’s Virtual and Physical SAN Misdirection

    I almost fell off my chair laughing as I read this post by Chuck Hollis that talks about using vSphere VSAN (Virtual SAN) with external storage arrays.  Is it the rantings of someone clinging onto the vestiges of a former life, or perhaps it’s a veiled way for VMware to start unravelling their failed VVOL… Read more »

  • Changing Consumption Models in Enterprise Storage

    Anyone who is involved in purchasing enterprise or midrange storage will recognise the story being painted in a recent blog post on the Pure Storage website.  The post introduces the concept of “Forever Flash” by first discussing the way in which storage is typically purchased. It’s true that vendors have manipulated the storage refresh cycle… Read more »

  • The Maturing of Flash Storage

    It’s interesting reading the comments that we’re added to my post of last week, discussing the summary of all flash arrays, initially started by Vaughn Stewart and continued by HP storage guy Calvin Zito. Unsurprisingly, most of the negativity came from EMC and their resellers, who are defending a late entrance into the market.  They… Read more »

  • XtremIO: What You Need to Know (Updated)

    With much anticipation, EMC has finally gone GA on their all-flash array, XtremIO, based on the former company of the same name they acquired in May 2012.  The eighteen months that have elapsed since then has seen the rise of an number of competitors and a lot of rumour, discussion and teaser presentations from EMC… Read more »

  • Avere Systems Embraces Cloud with Cloud NAS

    Cloud storage is a popular subject these days, with some good and some bad examples out there.  The appeal is obvious – data needs to be retained somewhere, whether it is of the primary, backup or archive flavour.  Being able to do that at low cost (especially when a large percentage of that data is… Read more »

  • What EMC Should Have Done With VNX

    My last post discussed the issues with EMC’s strategy around the marketing of their new VNX platform.  Some people will think picking holes in a vendor’s strategy is easy writing, so for those of that persuasion, I’ve taken the time to look at EMC’s portfolio and express an opinion on where EMC should go next….

  • Performance Tier or Capacity Tier? – No It’s the Working Set

    There have been a couple of articles on The Register over the last couple of days talking about EMC CTO John Roese and his use of the terms “Capacity Tier” for VMAX storage and “Performance Tier” for their flash solutions.  Sadly this shows EMCs CTO has an outdated view of the industry, is perpetuating old-school… Read more »

  • ScaleIO, EMC’s New Baby

    Keeping up the theme of innovation in storage (yes, it exists, you just have to look), earlier this week I had a chat to one of the UK folks at ScaleIO, the startup now acquired by EMC. ScaleIO are a software company selling a product called Elastic Converged Storage (ECS) that turns ordinary servers into… Read more »

  • Review: AWS Storage Gateway

    Cloud Storage Gateways provide the ability to write data directly into a cloud service/storage provider, either via a physical or virtual onsite appliance.  There are many vendors in the marketplace today and some are making serious money, (as reported by Chris Mellor today in The Register).  Amazon Web Services, seen as a leader in Infrastructure… Read more »
