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).

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 »

  • Flash Tiering – HP 3PAR Adaptive Cache

    I recently completed a white paper for HPE on a new feature in the 3PAR StoreServ platform called Adaptive Cache.  In disk-based 3PAR systems, flash SSD devices can be used to augment the DRAM cache.  This acts like a second level of memory tiering by cascading cached pages to flash rather than simply flushing them… Read more »

  • Avere Systems Releases Virtual Edge Filer To Deliver Data to Compute

    It’s been a little over three years since I first was introduced to Avere Systems at what was SNW Europe (now Powering The Cloud) in Frankfurt.  At the time, the positioning on their FXT hardware platform was as an edge “caching” filer to allow core NAS assets to be extended to branch offices without sacrificing… 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. The discussion (although I haven’t listened… Read more »

  • EMC XtremIO Destructive Upgrade Demonstrates Architecture Matters

    News has emerged about a potential upgrade issue with the latest version of O/S code for the EMC XtremIO all-flash platform.  As discussed in this blog post, the upgrade to XIOS 3.0 is not simply disruptive but is destructive.  According to Chris Mellor’s post, the reason for the destructive nature of the upgrade is to… Read more »

  • Why Have VVOLs Taken So Long to Deliver?

    Another VMworld has come and gone and still we haven’t seen the production deployment of VVOLs.  Just to recap, VVOLs are the evolution of the packaging of virtual machines that currently reside in data stores.  The main benefit is to be able to apply storage performance and availability policies to a VM object rather than… Read more »

  • Gartner Reveals Increasingly Irrelevant All Flash Array MQ

    Chris Mellor has posted a new ‘Register article that covers the inaugural Gartner Magic Quadrant for Solid State (or all-flash) Arrays.  It’s an interesting read, with EMC and Pure Storage topping the polls and IBM not far behind.  However as the use of flash within the enterprise has increased, the idea of a magic quadrant… Read more »
