Western Digital Redefines DRAM Caching

In a recent press release, Western Digital 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 an age where in-memory computing is increasing 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 »

  • You can’t trust what you read on the Internet – Unless it’s EMC

    Seems like Chris Mellor has struck a raw nerve with EMC and in particular Chad Sakac over this article he wrote for The Register.  Unfortunately Chad’s response makes him appear more like a spoilt child than a marketing professional who’s prepared to take the rough with the smooth in IT marketing.  Of course this isn’t… Read more »

  • NetApp: The Inflexibility of Flexvols

    I’ve just been reading up on Data ONTAP 8.0 as part of some ongoing work I’m doing.  You may be aware that version 8.0 of the filer operating system brings two major features; 64-bit support and the (sort of) integration of the Spinnaker code to create the multi-node version of ONTAP (called cluster mode). The… Read more »

  • Enterprise Computing: The Slow Demise of The Hard Drive

    Yesterday Nimbus Data Systems announced the release of their S-Class storage array.  What’s different about this storage device is that it uses purely NAND memory rather than traditional spinning disk.  With it’s arrival, we’re seeing another nail in the coffin of the traditional hard drive. OK, so the S-Class isn’t going to replace hard drives… Read more »

  • Enterprise Computing – Death of Tiering?

    I’m not the first to post on the subject of Netapp’s President and CEO Tom Georgens commenting during their latest earnings call on the apparent death of tiering as we know it today. In Netapp’s view, there will be no tiering of storage in the future.  Instead we will be using SATA drives for our… Read more »

  • Enterprise Computing: Thin Provisioning and The Cookie Monster!

    The Gestalt IT Field Day was a great success in bringing together a mixture of delegates from varying discplines. Following the presentations from 3Par and Symantec, there was heated debate about the implementation of Thin Provisioning and the ability to reclaim released storage resources. This post covers the basic concepts of Thin Provisioning and more… Read more »

  • Enterprise Computing: Why Thin Provisioning Is Not The Holy Grail for Utilisation

    Thin Provisioning (Dynamic Provisioning, Virtual Provisioning, or whatever you prefer to call it) is being heavily touted as a method of reducing storage costs.  Whilst at the outset it seems to provide some significant storage savings, it isn’t the answer for all our storage ills. What is it Thin Provisioning (TP) is a way of reducing… Read more »

  • Whatever Happened to Hybrid Drives?

    Over 18 months ago, I discussed in a post (here) the Hybrid Storage Alliance who were looking to increase the performance of hard drives by adding large amounts of flash to each device. But where are they now? A quick check on their website shows precious little information. In fact what’s on offer seems to… Read more »

  • Invista

    There’s been a few references to Invista over the last couple of weeks, notably from Barry discussing the “stealth announcement”. I commented on Barry’s blog that I felt Invista had been a failure, due to the number of sales. I’m not quite sure why this is so, as I think that virtualisation in the fabric… Read more »
