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 »

  • 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 »

  • 6TB HGST Helium Drive Continues Move to Two-Tier Storage

    Over the years, hard disk drives have steadily increased their speeds, peaking at 15,000 RPM, with only a fleeting attempt by Western Digital to push the boundaries up to 20K.  As we know, at that point solid-state drives became more viable than faster HDDs and manufacturers have reined back their aspirations.  Recently we’ve seen more… Read more »

  • NFS Vendor Benchmarks – Caveat Emptor

    This week we’ve seen an update on NFS benchmarks with Hitachi announcing their latest results (via Hu’s blog) using HUS File and FMDs (Flash Module Drives).  Of course Hitachi wouldn’t be announcing if they hadn’t beaten EMC with the figures; no-one releases data that makes them look worse, after all.  But what are the data… Read more »

  • The Psychology of Pricing

    It’s been another interesting week in IT.  Following on from recent rumours, Nirvanix have finally publicly announced they are closing down, replacing their website with a single holding page directing customers to IBM.  Yesterday, Violin Memory released their shares to the public and floated on the New York Stock Exchange.  Unfortunately there wasn’t a lot… 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….

  • Storage IPO Season – Violin Memory and Pure Storage

    It has emerged that both Violin Memory Inc and Pure Storage Inc are on the verge of initial public offerings, based on news articles last week.  Chris Mellor reports that Violin have filed for IPO, looking to raise $172m and in separate news, Pure Storage have raised a massive $150m in preparation for IPO some… Read more »

  • 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 »
