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 sealed
Blockages in the [...]

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. Cooling data centers is not just about refrigeration – there are lots of options – many of which we have written about here on The Hot [...]

I have spent the last 12 months working with some of the smartest and best funded marketing people on the planet, I have been working with the the really big, household name, IT Infrastructure vendors. I learned lots, lots about marketing, lots about honest analysis and lots about human nature. I learned that marketing isn’t [...]

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 differently [...]

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 [...]

Recently I spoke to David Emery a friend and colleague from my time at Coopers & Lybrand. He is now working on a major social media initiative for a global mobile telco. I was interested in David’s perspective as he has been working on a set of solutions to process log files at enormous scale. [...]

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 [...]

Most people who read this won’t have a clue what a Hollerith punched card is. I only just caught the end of the era at University where I learned to program in FORTRAN coding one punched card at a time.  Once the stack of cards was complete, I delivered it to the computer operator for [...]

If you have been following the storage business for a while, you will have noticed a few changes:

Introduction of Flash Memory components as Solid State Disks
Serial ATA (SATA) disks becoming popular and growing in capacity (2TB soon)

My old CIO at BT, Al-noor Ramji had a most delightful and endearing way of describing just how unimportant and disconnected IT Infrastructure is from reality by describing us as “The toilet cleaner’s toilet cleaners”. Like other successful CIOs Al-noor had the ability to cut through the noise and explain things as they are.

In every [...]

Both Seagate and Western Digital announced Q2 results last week perhaps signalling a return of confidence in the disk drive channel. Component manufacturers in the enterprise IT channel are an interesting bellwether of market confidence as orders need to be placed in advance of shipments of finished goods. There is a significant delay in revenue [...]

Around this time, analysts at ESG pull together a ten point list of predictions for the coming year. One of my areas of coverage and of expertise is in the Data Center around power, cooling, reliability and economics. So what’s different this year from prior years?
Strengthening fundamental drivers will likely make 2010 materially different from [...]

Today Microsoft and HP announced an expanded partnership in order to deliver fully integrated application to hardware stacks. It’s a brilliant move, absolutely stunningly smart and spot on for HP.
I wrote about Oracle VM and the fully integrated stack that Larry Ellison has been promoting to his customers. Superficially it might seem like a piece [...]

My good friend and ESG colleague Terri McClure @esganalysttmac recently blogged about a thought leadership piece I had presented at an analyst call last week. She made a very good job of explaining it and so I thought that I would write a little more about it here:
I call the concept the “Golden Triangle” and it [...]

My colleague at ESG John McKnight, just briefed some summary output from our IT Spending survey.  The results are presented below hot off the press. Security, Storage and Network see the biggest increases in growth but Virtualization software continues to lead in absolute terms.
It would be interesting to know how many Enterprises are looking to [...]

Here is a video from my friend Professor Masood Amin @Massoud_Amin who is the world authority on Smart Grid. If we want to save the planet from global warming, prevent terrorists shutting down our economy and prevent catastrophic failure of our power distribution systems. This is the template of what we need to do and [...]

For years I have been a prolific photographer of Data Centres all over the world. I have hundreds of images, some brilliant, some out of focus and under-exposed, (I am a data centre guy, not  a professional photographer).  I thought that I might publish some of the better ones with a bit of narrative about [...]

My friend and colleague Steve Duplessie at ESG just blogged about an interesting court case happening in the USA on The Bigger Truth.
“An e-mail archiving company, ZL Technologies, Inc., has sued, been dismissed, and re-sued Gartner – basically claiming that ZL’s placement in Gartner’s “Magic Quadrant” has caused the company damage – namely, that since [...]
