Western Digital Redefines DRAM Caching

In a recent announcement, Western Digital (or at least the HGST part of the company) announced the release of an interesting if not curious solution for extending DRAM with fast storage.  The Ultrastar DC ME200 extends server DRAM using proprietary caching software in an attempt to fully exploit the capabilities of modern multi-core processors.  In… Read more »

ESXi on ARM – Why?

This is certainly a question I’ve been pondering for a few weeks since the announcements at VMworld 2018 and where Ray O’Farrell presented ESXi running on an ARM Cortex A72 device.  Since my last post covering some VMware news, I’ve been asking – is there any logic in running a hypervisor on an IoT platform… Read more »

Technology First? Requirements First!

As more an observer of the technology industry these days, something struck a chord with me as I listened to a recent podcast recording.  Paul Stringfellow hosts a weekly podcast called Tech Interviews.  In Episode 77, he spoke to Matt Watts from NetApp on “cloud first” as a strategy.  The TL;DR of the discussion is… Read more »

HDD Capacity Threshold Reaches 15TB

Western Digital has announced what is currently the largest capacity hard drive available on the market today.  The Ultrastar DC HC620 has 15TB of capacity in a helium-filled 3.5″ form-factor.  This is a 7% increase (or obviously 1TB) over the 14TB drive announced in October 2017. Incremental The new capacity drive looks more like an… Read more »

IBM Buys Red Hat

Probably the biggest talking point this week is the announcement that IBM intends to buy Red Hat Inc, purveyor of the open source Red Hat operating system and an entire ecosystem of products around it.  The acquisition is interesting, firstly because of the attention it has garnered, but also for the implications to public cloud,… Read more »

Database Replication is Hard

I can only feel sympathy for the team at GitHub, after they suffered an outage recently, due to issues with database replication.  The problem was caused by a mere 43-second break in network connectivity.  We’ve all been there – keeping replicated data in sync is a thankless task and one that can be a nightmare… Read more »

Evolving Enterprise Storage Buying Models

One of the most tedious of tasks I’ve had to undertake over the years has been the planning and deployment of new storage technology.  In that respect, I’m not referring to the physical installation, but rather the process of capacity planning, sourcing and agreeing terms on new storage capacity.  Increasingly, internal businesses consume storage on-demand… Read more »

Building a modern data platform – exploiting the cloud

This is a guest post by Paul Stringfellow from Gardner Systems and was originally posted at “Building a modern data platform – exploiting the cloud” where you can also find Paul’s “Tech Interviews” podcast. No modern data platform would be complete if we didn’t talk about the use of public cloud. Public cloud can play a very… Read more »

Building a modern data platform – Out on the edge

This is a guest post by Paul Stringfellow from Gardner Systems and was originally posted at “Building a modern data platform – Out on the edge” where you can also find Paul’s “Tech Interviews” podcast. In this series so far we have concentrated on the data under our control in our datacentres and managed clouds and protected… Read more »

Building a modern data platform – Prevention (Office365)

This is a guest post by Paul Stringfellow from Gardner Systems and was originally posted at “Building a modern data platform – Prevention (Office365)” where you can also find Paul’s “Tech Interviews” podcast. In this series so far, we have looked at getting our initial foundations right and ensuring we have insight and control of our data… Read more »

  • The Evolution of Solid State Arrays

    In the first wave of solid-state storage arrays, we saw commodity style SSDs (solid state drives) being added to traditional storage appliances.  This solution provided an incremental benefit in performance over spinning hard drives, however the back-end technology in these arrays was developed up to 20 years ago and was purely focused around driving performance… Read more »

  • VMware vVOLS – More Than Just Individual LUNs?

    During the VMware keynote session today there was a minor discussion on the upcoming concept of VMware vVOLS.  Today, a virtual machine sits on a VMFS created on a storage LUN or on an NFS share.  An individual virtual machine consists of many files and in the case of VMFS-based VMs, is sitting on a… Read more »

  • Optimising Storage Architectures for SSD

    Last week I attended Hitachi’s 2012 Blogger Day.  Aside from catching up with some old friends, we were presented with some NDA stuff which will see the light of day soon.  In the meantime, I want to talk about a press release Hitachi made while I was still on holiday (and clearly missed as I… Read more »

  • August Storage Announcements – Pure Storage

    August seems to have been the month for a huge raft of storage-related announcements and I’m still getting to grips with the detail, after being away on holiday for the whole month.  As I start to pick out the news and make sense of how it fits into the storage landscape, I thought I’d start… Read more »

  • APIs Are Essential for Delivering Storage in Enterprise Cloud Infrastructures

    It’s pretty easy to pick holes in the current legacy storage products, especially when it comes to integration within both public and private cloud deployments.  However it’s worth discussing exactly what is required when implementing cloud frameworks, as the way in which storage is deployed is radically different from the traditional model of storage operations….

  • EMC Acquire XtremIO

    One of the worst kept secrets in the storage world is finally out.  EMC are acquiring XtremIO for a reported $430 million, as documented in a previous post. The EMC press release talks about XtremIO as “one of the world’s widely regarded Flash storage architecture pioneers”, yet they have no revenue or paying customers to… Read more »

  • Is Google Drive Too Late to the Party?

    Like many people, the other week I downloaded and installed Google Drive.  This is the long-awaited competitor to services like Dropbox and Microsoft’s SkyDrive.  It offers free online storage with the ability to upgrade to higher capacity at a cost.  Dropbox and the various other lookalikes have been around for some time, so is Google… Read more »

  • Could XtremIO Steal EMC’s Thunder?

    If the weekend IT press is to be believed, EMC are on the verge of acquiring solid-state array vendor XtremIO in a deal worth around $450 million.  This would be a remarkable outcome for a company that is still technically “in stealth mode” and has no obvious revenue or customers. Why would EMC do this?… Read more »

  • Primary Storage De-duplication: Only for SSD Arrays?

    I recently wrote an article for TechTarget that looked at the implementations of data de-duplication in primary storage arrays.  One of the things that stood out for me was the lack of de-duplication support in traditional (and some might say legacy) storage arrays. The cynical amongst us would say that the big 5 storage vendors… Read more »
