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 »

  • Hitachi Expands Flash Portfolio With Cheetah

    Just when we thought there were enough all-flash products on the market, Hitachi (or HDS if you prefer) has released a new line of all-flash systems under the brand name “Hitachi Flash Storage” or HFS.  The Cheetah reference in the title is the project name of the product during its development.  Before digging into technical… Read more »

  • Storage and Analytics – Creating Shared Knowledge

    A few years ago I worked with a company called Storage Fusion that provided a SaaS offering for analysing storage systems.  With a few simple scripts it was possible to collect the configuration information on one or more storage arrays and use that data to gain insights into metrics such as utilisation, performance and efficiency.  One benefit of… Read more »
