IBM's research labs - Cooling techniques

ntCabinets are fitted with rear-door heat exchangers, which suck in the hot exhaust air of the servers and blast it out again as cold air. The technology – the IP is owned by IBM – can take away up to 60 percent of the heat in a full rack, the company claims.

n

ntThe result of these changes is a datacentre PUE (power usage effectiveness) of 1.27, which generated a return on IBM’s investment within 10 months.

Easy Street data center

nttheEasyStreet, an IaaS provider, offsets all resources it consumes, resulting in zero carbon footprint operations in its Beaverton, OR data centers and offices. EasyStreet’s newest data center represents nearly four years’ research and design equity to build the most energy-efficient colocation facility in the region. Energy-saving technologies such as Indirect Evaporative Cooling and chimney cabinets reduce costs as well as carbon emissions while directing more power to customer cabinets.

ntAn innovative Indirect Evaporative Cooling (IEC) system from AMAXu00ae is key to efficiency. Direct Expansion (DX) packages provide supplemental cooling when required. (Estimated need is only 180 hours per year.)

Easy Street rooftop IEC

nt
• nttRooftop IEC units use an N+1 configuration.

nt

• nttEach IEC unit is connected to a shared supply and return trunk, allowing any spare unit to replace any failed unit.

nt

• nttHumidity is controlled with ultrasonic humidifiers operated by the master control system.

nt

• nttOverhead duct work distributes cooled air throughout the data center.

nt

• nttThe equipment cabinets are part of the cooling system. Chatsworth Products, Inc. (CPI) passive chimney cabinets are connected to the overhead return air duct work. They gather hot exhaust air and route it to the roof for processing.

nt

• nttA 25,000-gallon underground tank collects rainwater from the roof and supplies an estimated seven months of annual operation. It is filtered and used by the IEC units to cool the hot air exhausted through the return duct. Reclaimed water is supplemented by city water when necessary.

nt

• nttEfficient Uninterruptible VYCONu00ae Power Supplies (UPSs) use flywheels as their power source and require no acid-containing batteries.

Submerged data center

ntSubmerging your data center in fluid is definitely a next-generation method of temperature-control, but as ZDNet’s David Chernicoff reported in “Submerge your data center,” it is an intriguing option. Basically, specially designed server racks are submerged in a “dialectric” fluid, very similar to mineral oil. System fans aren’t needed, hard drives are encapsulated and airtight, and the thermal grease between the CPU/GPU and heat sink is replaced by Indium foil.

Cold War bunker turned cloud data center

ntAnother innovation in data center design puts old infrastructure to new use. In this case, a Cold War bunker in Switzerland was refitted to hold Radix Technologies cloud data center. Dug into Alpine rock, this installation was built to withstand nuclear blasts and features steel doors and reinforced concrete walls. Pictured here is an access tunnel between technology corridors. This is part of Toby Wolpe’s gallery, “Inside the Cold War bunker that’s now a cloud datacentre,” where you can view more photos of this former military site.

Verne Global data center complex in Iceland

ntThe 45-acre Verne Global data centre complex is located near Reykjavik, Iceland, minutes from Keflavu00edk International Airport. The facility is situated on the site of the former Naval Air Station Keflavik, a key strategic NATO base for over 50 years and chosen for its extremely low risk of natural disaster. Located well to the west of all of Iceland’s volcanic activity, arctic breezes and the Gulf Stream push volcanic effects away from the Verne Global site and toward Western Europe.

Geothermal valve - Verne Global

ntVerne Global’s facility has been designed to fully utilise Iceland’s unique environmental power advantages: 100% powered by renewable energy resources and 100% cooled by the natural environment of Iceland, without the use of chillers or compressors.

n

ntAll electricity comes from 100% renewable, geothermal and hydroelectric energy. Iceland is the only country in Western Europe that still has large indigenous amounts of competitively-priced hydroelectric and geothermal energy remaining to be harnessed.

Digitial Realty in London - Five halls

ntEach data hall has staging workspace for technical operations, with lift access, power and cooling facilities throughout. The vast data halls are also kept cool with the help of 14 CRAC (computer room air conditioning) units that can be found operating in an N+2 configuration (providing back ups) in each of the 1,000 square foot pristine data halls. 

n

ntThe datacentre halls are raised 4m above ground level and have an 800mm raised floor. The floor can take loads of up to 12.5KN/mu00b2.

Rackspace in the UK

ntRackspace’s Slough-based datacentre houses the hardware for its UK cloud, along with the other servers rented by its customers. It has 1,600 racks in place, of which 120 support its cloud.

n

ntRackspace’s server hardware is predominantly supplied by Dell. It operates a multi-vendor networking approach: Cisco is the predominant provider of switching technology, while Juniper Networks supplies backbone services and Brocade provides equipment for load balancing.

Rackspace cooling system

ntThe datacentre has a power usage effectiveness (PUE) rating of 1.7, though Rackspace hopes to lower this to an average of 1.59 once the third data hall is built.

n

ntCooling is achieved via computer room air-conditioning (Crac) units that pass cold air through the underfloor plenum. The current is then lifted into the servers and expelled as hot air at the back. Unlike numerous other datacentres, the racks are not enclosed.

Virtus security controls

ntDatacentre security is vital: there are biometric readers and secure mantraps on both levels of the datacentre that control access to the datahalls and are programmed so that the first set of doors must close before the second set opens. Each door has a proximity card reader that is pre-programmed with a client’s access information.

Las Vegas Sands

ntThe Las Vegas Sands Corporation runs two casino resorts in the gambling mecca, the Venetian and the Palazzo.

n

ntThe two establishments run off the same infrastructure, which uses 300 servers to support more than 11,000 suites and rooms, 3,000 slot machines and 200 gambling tables, and run nine websites. The bulk of the Venetian and Palazzo’s core systems run on six IBM’s iSeries servers (pictured), formerly known as AS/400s.
