EMC, HDS & NetApp Storage Portfolio Videos now available on YouTube

As well as being one of the most expensive, your storage infrastructure is likely to be the single most critical element of your physical and virtualised IT environment. While CPU, RAM and Network resources can directly affect the performance of some of your systems, poorly sized or badly integrated storage, will damage the performance of ALL your systems and may render servers and services unusable. So it’s always worth taking the time to understand the storage that’s available and digging a little deeper to ensure it’s going to deliver great performance and good value for money. To start the ball rolling, we’ve provided three short videos that give a quick introduction to the storage offerings available from the three major storage Continue reading

Managing Education … in a Flash!

I’ve had the privilege of working with a number of education institutions over the past fourteen years. In that time, through the progress of Virtual Learning Environments, Interactive Smart Boards and BYOD there has always been one piece of the IT puzzle in academia that has required extra attention and resources. I speak of course about the Management Information System. Be it Unit-e, SIMS or EBS running on Microsoft SQL or Oracle, it is the core information system that tracks the life-cycle of the learner. The MIS also provides a framework for managing curriculum portfolios and feeds assessment information and outcomes into data warehouses. And, as you are no doubt aware, accurate and timely returns are crucial to securing the correct levels Continue reading

Comparing EMC, HDS and NetApp All-Flash and Hybrid block arrays

Flash has changed storage forever and almost every new array purchase needs to have some degree of flash included, so the market now offers three distinct types of array: Hybrid – Exploits the performance of flash and the lower cost of HDDs All-Flash hybrid – Packaged to deliver a low cost per GB of flash Ground-up design – Purely designed for flash with no support for HDDs As always there is a huge range of price points, due to the architecture, features and performance scaling, for these arrays. Efficiency features are critical in some use cases (i.e. VDI), but less so in many others and performance scaling for the majority of solutions is substantially higher than legacy arrays built just for Continue reading

HUS 100 Offers a Unique Take on Dual Controller Architecture

I’ve been working in the storage industry for many years and even after all this time, I still find it rewarding and exciting to see how things actually work. Getting to the bottom of things is not always easy, but I guess that’s what makes it fun! Recently,  I’ve been having a closer look at HDS and the HUS 100 storage family and I wanted to share a cool piece of tech they call the Dynamic Virtual Controller. Most mid-market storage arrays offer a dual controller system. The architecture is something like this: Controller A and controller B are both x86 computers  (perhaps running a Windows or Linux derivative) Controller A and controller B both have access to the underlying disks (not always – but most of the Continue reading
