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.

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 »

  • Rethinking Data Protection in Public Cloud

    This is the first of a series of posts that will start to dig down into the issues of data protection within public clouds,  This post covers some outline thinking. The most apt definition of public cloud is that it is simply somebody else’s computer.  You’re renting time and services from a provider, services which… Read more »

  • Has NVMe Killed off NVDIMM?

    Update: I’ve added extra links at the end of this post, covering some background reading/watching from SNIA. According to a recent article on The Register, Diablo Technologies appears to have closed down.  Diablo was or is a manufacturer of NVDIMM and DRAM extension technology, including Memory1.  As previously reported, many of the original founders and… Read more »

  • Public Cloud Comparisons – Account Creation

    I’m doing a little more structured work with public cloud, so have been going back and cleaning up and standardising the existing accounts I already have.  The first thing is to create accounts that are company, not user specific.  I like to use distribution groups or mailing lists for setting up accounts.  They are more… Read more »

  • Delivering File Protocols on Object Stores

    When object stores first started to appear on the market, the aim was to target a very specific niche.  Unstructured data growth demanded better ways of storing data than file servers.  Object stores offered the ability to scale to billions of objects, without the issues of managing a file system.  However, rewriting applications for REST-based… Read more »
