Fresh Thinking on IT Operations for 100,000 Industry Executives

All Posts Tagged With: "Power Density"

I just finished writing an interesting white paper on Data Center Infrastructure Management for Rackwise Inc.  DCIM is not all about cost, although we would be remiss not to take the significant cost advantages available by properly managing our data center estate. The white paper picks up on a number of key themes in Data […]

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 […]

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 […]

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 […]

Last week I met with my friend Steve Sole of Nubis who wanted to tell me about the work they have been doing in data centers around improving energy efficiency. Nubis make demountable Aisle Containment systems – they don’t care if it is Hot or Cold Aisle – the objective is to stop the air […]

Recently The Hot Aisle conducted an online survey asking the question – “How do you currently choose where to place equipment in your data centre?” As usual we got a very large response to the survey with 5,580 respondants. The results are in and it shows quite clearly that equipment placement is (to say the […]

Next week, Iceotope will announce that it has developed, patented and manufactured an extreme IT equipment cooling solution.  The solution tackles the problems of cooling servers in data centres all the way from the actual source of the heat – at the processor and memory component level – to its final destination – outside air by […]

I met with Dr. Bruno Michel who is IBM’s, Zurich based, advanced thermal packaging manager yesterday. We spoke about IBM’s view of cooling technology in the 5 to 10 year horizon and what I heard was interesting and credible. IBM have been working with liquid cooling for some time, in the HydroCube, in the new […]

Anyone following the news will have seen that Verari and Cisco are working closely together on developing the highest density UCS deployment so far. My friend Dan Gatti at Verari just sent over the latest photograph from the Verari manufacturing plant. A FOREST Data Center Scale container full of UCS and Nexus. This really demonstrates […]

I recently had a conversation with Mark Anzani, IBM’s CTO for System z, the mainframe platform. Regular readers will know that cooling technology is a favourite subject here on the hot aisle and I was keen to get an answer to how IBM plan to cool their next range of machines, the z11 series. IBM […]

I am on the West Coast of the US this week visiting with NetApp in Sunnyvale again. On this trip I had the opportunity to visit a couple of NetApp’s internal data centers (B11 and the impressive B2 sites) with Cesar Orosco, NetApp on NetApp IT Architect. Cesar is charged with using NetApp technology in […]

We are all trying to fix the unfixable in the Data Centre. How do we get more cooling capacity from sites we built a decade ago for low power density applications? One of the biggest problems is that everyone is trying to work against a basic law of physics; hot air rises, and cold air […]

Interxion, a European operator of carrier-neutral data centres, announced today that the first 1,200 m2 of its new 7,000 m2 Amsterdam data centre—its fifth Amsterdam-area centre—is now operational. 70% of the first phase has been pre-sold to online retail, finance, and ICT customers. Growing customer demand has accelerated the construction of an additional 1,100 m2 […]

Today we are going to look at how fire detection systems can be used in Data Centers to prevent catastrophic loss and damage; we will focus on Very Early Smoke Detection Systems, (VESDA – Very Early Smoke Detection Alarm). Without an efficient and safe environment, there is no way to be assured of business continuity. […]

My friend, the inventor and green innovator, Peter Hopton from VeryPC has a unique view on how to be environmentally responsible whilst deploying PCs into an office environment and he is presenting his ideas at The Carbon Footprint Energy Efficient IT Summit on the 4th and 5th September. Peter says that there are three basic […]

  You may be very surprised to see that McKinsey believe that Data Center costs are 25% of all IT costs. Many CIOs will find it difficult to reconcile this view with their own budgets. There are a two key reasons why this is a difficult and badly understood process. Within many organizations many of the […]

I have had a great interchange from a subscriber to The Hot Aisle:- Darek Wichniewicz of ATM SA in Warsaw, Poland. Darek is looking for some real technical advice on building a new Data Center facility of 2000 – 3000 square meters utilizing fresh air cooling. Like many Data Center operators Darek is concerned about being […]

A key management principle is that you can’t manage what you can’t measure. So if we want to manage the energy efficiency of our data center estate, then we had better be in a position to baseline where we are today so that we can identify the value of the changes that we implement. The […]

The consequences of data center failure can be pretty catastrophic for your business, so unsurprisingly, you will have very high expectations about availability and reliability. Unfortunately for many of us, our expectations will not be met by reality. Very often the system that is our data center facility is significantly less reliable than we might […]

DC Power in Data Centres The discussions amongst Data Centre specialist about the relative benefits of AC and DC are by far the most heated. In my opinion these are mainly driven by the technology that the protagonists are most comfortable with. The 20th Century Data Centre guys are all into AC, it is what […]
