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 »

  • Samsung Introduces 8TB NF1 NVMe SSDs

    Samsung has recently announced an 8TB NF1 format NVMe SSD.  NF1 was originally called NGSFF (Next Generation Small Form Factor) and is intended as a replacement for the existing M.2 format drives.  With 15K and 10K drives disappearing from the market, is it time to accept we should move on from legacy HDD drive sizes?… Read more »

  • Avoiding the Storage Performance Bathtub Curve

    We’re probably all familiar with the concept of the HDD or SSD reliability bathtub curve (figure 1).  This shows how over the lifetime of a drive, failures typically follow a pattern where failure rate increases over time to a steady state, then increases again as the device wears out.  But have you considered the idea… Read more »

  • The Britpop Battle of Rubrik and Cohesity

    Were you a Blur or Oasis fan?  Perhaps you were on the side of Jarvis Cocker and preferred Pulp.  Whatever your choice, the Britpop wars of the 1990s were memorable for building hype around the UK music industry and the idea of Cool Britannia. In lots of ways, the evolution of the data protection industry… Read more »

  • NVMe over Fabrics – Caveat Emptor?

    For the past 20 years, Fibre Channel has been the dominant enterprise data centre storage networking technology.  By this, I mean traditional Fibre Channel, not variants that work over IP or use Converged Ethernet (more on that in a moment).  It’s true that other protocols exist.  Smaller organisations have typically used iSCSI, because of the… Read more »

  • IDC 1Q2018 Data Shows a Rebound for Storage Hardware Sales

    The latest IDC Storage Tracker numbers are out and in the spirit of recent analysis, I’ve put the numbers into my tracking spreadsheet.  The figures represent data for Q1, which now has 12 years’ worth of coverage.  With around 42% growth in the general storage hardware figures and 20% in external storage sales, the numbers… Read more »

  • Avoiding All-Flash Missing IOPS

    We are living in a golden age of storage media, where new products come to market offering ever greater performance with lower latency than previous generations.  Today the hard drive and even early flash drives look positively archaic compared to modern NVMe drives built from 3D-XPoint, capable of delivering hundreds of thousands of IOPS and… Read more »

  • The Race towards End-to-End NVMe in the Data Centre

    The next greatest thing in storage hardware is the move to NVMe.  This is occurring in two ways – conversion of internal designs within shared storage platforms to use NVMe at the “back-end”, and front-end (or host connectivity) using NVMe over Fabrics in some form.  Vendors are starting to use the term “end-to-end” NVMe as… Read more »

  • Micron ushers in the era of QLC SSDs

    To date we’ve only seen QLC NAND storage in the consumer SD card format, however, that’s set to change as Micron announces the first QLC SATA SSD for the data centre.  The Micron 5210 ION SSD will deliver up to 7.68TB of capacity in a standard 2.5″, 7mm form factor.  But there’s a catch –… Read more »

  • Conflating Data Protection and Data Mobility

    Sitting on the sidelines, I’ve been watching some of the traffic and communications coming from VeeamON this week.  Chris Mellor just posted a quick article summing up the ambitions of Veeam as a company.  It struck me that we continue to conflate the idea of data protection and data mobility.  To me, these are two… Read more »
