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 »

  • The Fall of STEC and Rise of Western Digital

    In a news announcement yesterday, STEC Inc, makers of solid state flash drives (SSDs) announced a “merger” with (i.e. was acquired by) Western Digital, one of the leading hard disk drive manufacturers.  It’s a spectacular fall for a company that at one stage had a share price of over $41/share in September 2009.  However an… Read more »

  • HP 3PAR 7450 All Flash Array

    I mentioned in a previous post that I would delve a little deeper into what HP have done to optimise performance on the new 3PAR 7450.  I was lucky to be able to catch up at the 3Par booth with Priyadarshi Prasad, who works in marketing for HP 3PAR.  We took some time to talk… Read more »

  • ViPR – Frankenstorage Revisited

    Cast your minds back to 2009.  At that time, Chuck Hollis wrote a blog post that quoted the following definition: “Frankenstorage appears to be a new twist on [the Frankenstein] idea — storage arrays, assembled from various parts from multiple vendors, brought to life by the magic of powerpoints and press releases.” The crux of the… Read more »

  • Defining Software Defined Storage

    The term Software Defined Storage has generally accepted within IT as a process for delivering storage without the lock-in of hardware from the vendor.  How has our understanding of the term evolved over recent years? It’s easy to use the examples of server virtualisation and networking as reasons why thinking of storage virtualisation for SDS… Read more »

  • Review: AWS Storage Gateway

    Cloud Storage Gateways provide the ability to write data directly into a cloud service/storage provider, either via a physical or virtual onsite appliance.  There are many vendors in the marketplace today and some are making serious money, (as reported by Chris Mellor today in The Register).  Amazon Web Services, seen as a leader in Infrastructure… Read more »

  • Violin Memory acquires Gridiron Systems

    Yesterday, Violin announced that they have acquired Gridiron Systems, a vendor of cache acceleration hardware and software.  At the outset it may seem odd that an all-flash vendor would want to acquire a company offering acceleration for traditional arrays, however this could be a very smart deal indeed in a number of ways. Software is… Read more »

  • Storage QoS – How Hard Can It Be?

    Following up from yesterday’s post and the comments received, I thought it was worth considering how hard it would actually be to implement quality of service within a storage array. Almost all storage arrays available today (whether physical or virtual) work on the assumption that I/O should be delivered as fast as possible.  This is… Read more »

  • Storage QoS In The Cloud

    Last year I did some research and wrote up a couple of posts on Cloud Compute performance.  One feature that seems to get left out somewhat is storage I/O performance; the cloud offerings talk about capacity, but rarely reference performance. Recently, I reviewed the options available from the major providers and found two new storage performance offerings…. Read more »

  • Vendor Lock-in with Cloud Storage – Good or Bad?

    There have been two interesting and contrasting announcements covering cloud storage in the last couple of weeks.  The first was NetApp, who have announced “NetApp Private Storage for AWS”.  which seems to a proprietary way of replicating data into the AWS cloud.  The second comes from Nirvanix and Violin Memory; Violin have deployed their all-SSD… Read more »
