DataCloud 2018

Vi beklager å måtte meddele at DnD i år har bestemt seg for å kansellere årets studietur til DataCloud 2018, 12-14.6, i Monaco. Det viser seg at arrangøren i år har valgt et 3 dagers program og vi vil derfor ikke kunne tilpasse vårt program som vi pleier. For de som ønsker å delta vil vi anbefale å melde dere på via denne linken. http://www.datacloudcongress.com/accommodation Kjetil Ertnæs, som har vært reiseleder på studieturene tidligere vil også i år delta på konferansen og han vil ta initiativ til en felles "Nordisk" middag 13.6. De som ønsker mer informasjon om dette, vennligst send Kjetil en mail på ke@dle.no. #Nyhet #Aktuelt

Will Eco-Mode UPS Be ‘Finished Off’ by Carborundum?

The power losses in static-UPS have gradually decreased over the past 20 years or so. From the early days of thyristor based series on-line (usually referred to as double-conversion or, now, IEC ‘VFI’) with transformers at the input and output and full-load operating efficiency of 83-85% to transistor (IGBT) based line-interactive (VI) transformer-less machines achieving 97.5-98% we have seen a huge improvement; Energy efficiency increased by 15% plus a drastic reduction in cooling capacity Reliability increased, with a module MTBF rising from <25,000h to >150,000h Output voltage waveform improved from >5% to 1% distortion from a sinewave Input current harmonics down from 33% to <2% Foot-pr

The Weakest Link in High Availability Power Systems?

In every data centre power system, there is a weakest link. The art is to minimise the weakness through smart design but, as most data centre failures are attributable to human error, we also must consider the ‘operations’ phase, including regular maintenance, repairs and emergency intervention. That said there will always be a weakest link since as we reinforce one element another takes its place at the bottom of the league table of resilience. So, the question remains: Which, if any, power system element is always the weakest link? A clue as to where to search may lay in a conference presentation made a couple of years ago by the manager of a major ICT organisations’ north American dat

The Drivers of Data Centre Power?

Most governments in Western Europe, coordinated with EU policy initiatives, are trying to meet carbon reduction targets and weed us off of fossil fuel based generation at the same time. The overriding target is to become ‘sustainable’ and, in classical environmental terms, this is achieved in three distinct stages: The first step is a reduction in demand, followed closely by increased process efficiency and, finally, the third step to sustainability, is powering the resulting slimmed down demand from low/zero carbon, predominantly renewable, energy sources. Whether or not this includes nuclear fission is a debate to be had elsewhere but, from an engineering perspective, nuclear generation

Is Resilience Misrepresented, as Well as Misunderstood?

When it comes to data centres the word ‘resilience’ can be best defined as ‘the ability to maintain ICT service in the face of environmental extremes as well as human error or deliberate sabotage’ and, generally, higher levels of resilience can be engineered into the mechanical and electrical infrastructure at a cost premium. However, ‘human error’ is well documented to be the root cause of 70% of all data centre ‘failures’ but even that can be reduced by design e.g. a dual-bus power system with a UPS in each bus can largely protect a correctly connected dual-corded load against power failure, human error and inept sabotage but you probably notice how careful I am with the caveats… Of cours

A Perfect Electrical Storm?

The interaction of various components, performance characteristics and fault events may force us to reconsider electrical protection in the data centre. The result may suggest that fuses, long considered old-fashioned in data centre power distribution, may prove to have a future in the pursuit of uptime. In the simplest scenario we could have one critical load connected to one power supply. If that load suffers an internal short-circuit then the electrical protection system disconnects the entire load (e.g. in 0.1s) to limit physical damage and danger to human life. However, the problem we are considering here is if several critical loads are connected to one power distribution point (e.g

Predictions and Forecasts?

Most of us like a bit of speculation and making lists so this month, when asked for ‘predictions’, I have decided to make a list of my top three. The first in my list, ‘in no particular order’, concerns ASHRAE and their Thermal Guidelines for microprocessor based hardware. We, the data centre industry in Europe, are very lucky to have ASHRAE. OK, they are a purely North American based trade association that serves its members but they are the sole global source for the limits of temperature, humidity and air-quality for ICT devices and have proven themselves to be far more progressive for the environmental good than anyone could have expected. If you follow their guidelines from the first

Generator Rating Is Not as Easy as It Used to Be…

I’m going to upset a few folks so I may as well go for a whole bunch all at once. My aim (or is it simply ‘target’) is to vent a growing personal frustration with what should be a simple task – deciding the rating of a data centre standby generator. By ‘rating’ I don’t only mean ‘power’, that is a straightforward summation of the worst case (all the possible loads including battery charging on the hottest day of the year etc) or a deliberate design decision to cater for partial load, but also for how many hours per year (all the way up to 100% of them) I want the machine(s) to be able to deliver that power. For those of you who are already bored, or just wondering where I am meandering ‘to

The Pros and Cons of Eco-Mode UPS… What Does the Future Hold?

In the early days of thyristor based series on-line (usually referred to as ‘double-conversion’ or, now, by the IEC Standard 602040-3, ‘VFI’, Voltage and Frequency Independent) with transformers and filters at the input and output the highest full-load operating efficiency you could expect was 83-85% and partial load efficiency was much lower, mainly due to the transformers. This has gradually increased over the past 25 years mainly due to a move to transistors (IGBT) that enabled the removal of input filters, isolation transformers and output filters. Added to that shift in technology many UPS are now based on line-interactive (‘VI’, Voltage Independent in the IEC Standard) topology trans

Are We Europeans’ Piggy-Backing North American Data Centre ‘Standards’?

This is a question that I heard just the other day and the best answer is probably ‘yes’ with a small but growing ‘no’ caveat. At the root of the problem is that there is widespread confusion as to what constitutes a ‘standard’ since there is no authoritative definition but I personally differentiate between a Standard (upper-case ‘S’) and a Design Guide or Best Practice document by defining it as a National or International document that that has been agreed by widespread industry consent and, hopefully, being as non-commercially based as is possible. The last point is subjective as Standards’ bodies around the world depend upon expertise to draft their documents and that expertise nearly

As You Design for a Low PUE Do You Sacrifice Availability?

As you design for a low PUE do you sacrifice Availability? A few weeks ago I was pleased to be asked to speak at the opening ceremony of the new EVRY data centre facility in Fetsund, Oslo – complete with lots of razzmatazz hosted by a TV chat-show star and even with a government minister rolled-out especially for the event. As I sat waiting for my slot on the agenda I listened to the opening address and a presentation by the developer and a phrase popped into my ears that made me adjust what I was going to say when it was my turn. The phrase was ‘no compromise’ and it was aimed at the facility design. Now, my talk was centred on the reasons for data centre power growth and the reaction of

Is the ‘Cloud’ More, or Less, Resilient Than Your Own Data Centre?

The latest outage in Microsoft Azure services, 31st March, was in Japan and lasted over 7 hours until ‘most’ services were back on line. This follows a similarly long Azure outage in 2014 that was eventually blamed by Microsoft on ‘human error’. The press release makes interesting reading and this month I will attempt to pick through the snippets of information and come up with a slightly more useful lesson-to-learned on the press release’s title; ‘UPS failure causes cooling outage’. Of course, 7 hours of downtime in a year is only 99.9% Availability – much lower than any end-user would accept from their own facility - and If you consider a ‘finance’ application then a failure once every c

Artificial Intelligence in the Data Centre?

This month I have been asked to write about the opportunities for optimisation provided by applying artificial intelligence (AI) in the data centre, and immediately struck by the thought that applying human intelligence would be a good place to start! Is it ‘intelligent’ to refrigerate hardware that can run continuously at 32°C inlet or design for full load when most facilities never rise above 50% for the first 5 years or to fit bullet-proof glass, biometrics and vehicle-traps into a facility that mainly houses a price-comparison web-site for on-line dating services? Anyway, let’s look at AI first. Intelligence is an attribute that enables the possessor to assimilate and process informati
