The whole reseller business model has changed

IT resellers operate in two key market segments left to them by the large IT vendors: The mid-market (firms of up to 1000 staff) for general IT systems and platforms Tight vertical markets where the reseller has a great deal of skill and capability often supported by intellectual property In both these areas customers and [...]

Enterprise Flash Storage is not all the same

There are three generalised approaches to using flash memory in storage architectures, categorised in the diagram below: Three Categories of Solution Design The Performance Optimised category takes a no-compromise-on-cost approach to designing for performance. A centralised storage controller that leverages flash memory characteristics to dramatically reduce IO latency and improve IOPS. Significant new engineering work [...]

Solid State Storage changes everything

I interviewed Ron Bianchini CEO of Avere Systems about their new third generation FXT appliance. (Ron was the CEO of Spinnaker Networks acquired by NetApp in November 2003 for $300M). We started the conversation by looking at the key values of Spinnaker, it’s ability to scale and cluster NAS filers, a technology long since incorporated [...]

EMC Validates Solid State Storage as best for UCS Platform

I just finished reading EMC company blogger, Chuck Hollis article about EMC VFCache, a server side flash storage technology that competes with the Fusion-io, ioDrive head on.  Most interestingly, the product name is chosen carefully to ensure customers don’t get confused that VFCache might be designed to replace the normal disk based EMC storage array controller products.  [...]

Around this time, I usually pull together a ten point list of predictions for the coming year. I am interested in the Data Center (around power, cooling, reliability and economics), IT Security (particularly Database and Mobile), Big Data and Storage (Particularly Solid State). So what’s different this year from prior years? Strengthening fundamental drivers are likely to [...]

Looks are deceiving, and in the data center they can be confusing. If you are doing a good job your Power Usage Efficiency (PUE) might get worse! Energy consumption in the data center is the result of two interactions: the cumulative IT Load from all the information technology hardware combined with the facility power and cooling [...]

Last night a few friends (IT Operations Geeks like me) and I had a great “Brains Trust” event at the OXO Tower in London. The topic was a continuation of the last Hot Aisle blog entry Why do we try to solve backup when restore is the problem?  Apart from the food, view and wine [...]

I have been thinking about data storage and protection recently and how our behaviour is driving massive growth in cost and complexity.  The issue seems to eminate from the fact that we focus on solving backup when the real problem is restoring data: We need to be able to deal with data corruption and incorrectly [...]

Google has the most amazingly clear terms of service for their cloud products.  The terms are take it or leave it, no promises, no commitments and no come-back. I love the statement that there is no warrant that the quality of services will meet your expectations. It’s a gem.   Thanks to Harqs Singh for [...]

Yesterday Chris Leahy (my Technical Facilities Manager) and I were agonising over why we had low plenum pressure in our Data Center and why we were seeing symptoms of hot air trapped in the roof void. We looked at all the normal stuff: Leaks in the plenum space Badly sealed floor Cable access holes improperly [...]

Worldwide, there has been a lot of focus in recent years on reducing the environmental impact of Data Centers. Green always comes at a cost, but once it is viewed as a long-term investment rather than as a quick return on investment (ROI), it can be a viable cost cutting option. Data center investments are [...]

Throughout my 20 plus year career in IT consulting, I have noticed that the most successful businesses often have something in common – they run their IT like a business and they treat IT like a key part of the business, and not like an add-on function.  I have been in Qatar for only just [...]

I don’t normally plug press releases straight from vendors but today I received an email from Emily Wood at Google with a message that I agree 100% with.

The problem with computing is everyone wants to make it uniform – fit it into a neat box, categorise it as ‘all the same’, make it autonomic, self-managing and move on. In fact, IT is anything but uniform, so these simplistic approaches fall at the first hurdle. Smart CIOs understand applications need to be treated [...]

There are a lot of them around, Data Centres. A few of them are designed and operated very well and deliver great Power Usage Efficiency. Some could do a bit better, perhaps an airside economiser or two, or some hot or cold aisle containment, or maybe some DC power. Some are just a nightmare and [...]

Cloudera struck lucky in getting a $5M A-round away just before the markets shut down in response to the collapse of the global financial system. Backed by Accel Partners and more recently Greylock Partners they are making a bet that Hadoop with a smart scale out approach to managing large amounts of data is a [...]

A while back I met Kathrin Winkler, Chief Sustainability Officer at EMC. She was delivering a briefing about EMC’s Corporate Social Responsibility (CSR) activities to a group of industry analysts. Most CSR briefings are as dull as ditchwater and devoid of anything remotely innovative or challenging. CSR is for some just going through the motions [...]

Data Centre design is an evolutionary process and we can see the first signs of significant change in the latest sites. Co-generation, liquid cooling, cloud computing, high density are all likely to feature in the 2020 Data Centre. How are you placed with your existing Data Centre investments to take advantage of these changes? Will [...]
