Containment – the key to effi cient cooling

Data centers that rely on simple hot/cold aisle methods over-cool

nearly 2.5 times to compensate for the mixing of hot and cold air.

• New server designs exhaust air in excess of 140˚F leading to

very hot aisles and challenging working conditions

• On average, 60% of available cooling is wasted due to bypass

and re-circulation airfl ow

• Air is supplied well below ASHRAE temp limits to address hot air

contamination and attempt to control temperature at rack intake

• Despite gross over-cooling, 10% of racks experience hot spots

Without heat containment, hot air mixes with cold leading to gross over-cooling.

Reference: ASHRAE Journal Article - Designing Better Data Centers, 12/07

EPA - Uptime Institute conference material

Studies show 250% over-cooling required when hot air is uncontrolled.

The Value of containment cooling

By containing and directing heat, the Geist cooling method

maximizes effi ciency while easily maintaining an ideal temperature

throughout the data center.

• Contains and evacuates 100% of the heat - no heat mixing with

the cooling simplifi es the cooling circuit

• Heat exhaust direct from the cabinets eliminates cool air bypass

• Maximizes chiller plant effi ciency with highest possible return air

temperatures

• Expertly manufactured chimneys and rack enclosures eliminate

makeshift solutions like vinyl plastic sheeting

• Maintains a perfectly controlled and consistent IT environment

Stabilize IT intake air temperature to within a few degrees of the supply air temperature

at all points in the data center. Full heat return - cool air bypass eliminated.

Geist manufactured chimneys and enclosures capture hot air and expel it beyond the

cold air surrounding the cabinet rows.

Containment Cooling

Maximize IT density and lower operating costs by relentlessly

controlling hot air; automated feedback cuts total fan energy 40%.

Active Cabinet or Row Containment MethodGeist’s cooling philosophy centers on two critical components

1) containing heat, 2) expelling heat directly to the CRAC units.

This two-step focus maintains the ideal temperature for data

center equipment. The first step is addressed by Geist’s expertly

manufactured chimneys and enclosures. The second step relies

on sophisticated temperature and pressure sensors to control

fan speeds and exhaust hot air through the chimneys at the

most efficient rate. The combination of hot air containment and

intelligently controlled fan speed creates a consistent climate

controlled environment in the data center and within the cabinet

rows.

• Hot aisle/cold aisle layout eliminated

- With hot air contained, data center room becomes a comfort

aisle for ideal working conditions

- Eliminates hot air mixing, wrap around heating and hot spots

- Bypass eliminated, 100% use of cooled air

• No row based cooling units to take up fl oor space

• Complete hot air separation enables highest CRAC/CRAH return

air temperatures

• Actively balances return air fl ow with cabinet supply requirements

• Eliminates raised fl oor pressure balancing issues

• Suitable for slab or raised-fl oor environments

• 1:1 air fl ow balance makes cooling over-provision unnecessary

• Allows for more densely populated cabinets

With hot air contained, data center room maintains a “comfort” temperature for working conditions. Hot air separation enables highest CRAC/CRAH return air temperatures.

Sophisticated temperature and pressure sensors control redundant fan

speeds to exhaust hot air through the chimneys at the most efficient rate. Plug and play fan units make for easy installation and maintenance.

Common PlenumWith Geist’s customizable cooling components, a common air

plenum can be created across multiple cabinets. The common

plenum then allows multiple Geist cooling units to work in

concert by utilizing the IP network. This approach provides

scalability as required and lowers the total cost of deployment.

Plenum components allow Geist cooling units to be installed

every 6 inches. This fl exible system placement avoids overhead

obstructions such as cable trays.

Load Sharing• Multiple systems work together to share cabinet loads

• Operational redundancy increases as systems work in concert

• In the event of utility failure, heat continues to be exhausted by

the Geist cooling unit connected to your UPS

Automated Control• Automated load balancing eliminates micromanaging airfl ow

requirements

• Automatic notifi cation of system threshold breach via email or SNMP

• Environmental conditions monitored and reported automatically

• Geist’s Environet software aggregates total air fl ow load and automates

defi ning total air fl ow requirements, allowing lowered air fl ow across the

data center, saving 40% fan energy.

Scalable Capacity• System capacity automatically scales as loads are added or removed

• Automated load sharing returns all heat directly to return air plenum

• High density loads can be directly coupled for single cabinet isolation

• Load sharing leads to lower cost per deployed kW, allowing all fans

to run at energy effi cient speeds

A common air plenum across cabinets allows multiple Geist cooling units to work in

concert utilizing the IP network to communicate as one unit. Optional placement of

Geist cooling units, avoids overhead obstructions such as cable trays.

Multiple layers of system redundancy increase as systems work in concert.

Multiple systems work together to share cabinet loads.

Passive Containment

Headline needed ----------------------------------

With the Geist passive containment option, every cabinet can

be appropriately controlled. Low density cabinets can take

advantage of the passive chimney system but can be easily

upgraded as they mature and loads begin to increase. Our

solution grows and adjusts to the data center’s needs. You can

feel confi dent that you are not limiting your cabinet’s capacity due

to reaching the limits of the passive option.

To maintain proper air fl ow and prevent air recirculation, Geist

offers a variety of cabinet blanking panels. A rack without

proper blanking panels can result in thermal damage due to

improper cooling as well as excessive energy consumption

and an increased carbon footprint. Each Geist blanking panel

is engineered with an overlapping lip for an improved seal to

prevent hot air from escaping to the front of the cabinet.

Blanking Panels Block unnecessary mixing of hot and cold air.

Eliminate network switch heat related failures by

strategically targeting the problem area.

Network Switch Cooling

Geist’s switch cooling product line allows network switches to

breathe cool air regardless of where they are mounted in the rack.

Mounting switches in the back of the cabinet does allow for more

convenient cabling connections. The trade-off is that the switch is

fed air that has already been pre-heated by the servers.

The Geist network switch cooling products are available in a wide

range of confi gurations and rack space sizes. Designed to work

with 1U to 9U devices and beyond, having the ability to channel

air to every kind of intake / exhaust confi guration imaginable such

as side in - rear out, front in - side out, rear in - front out. Geist’s network switch cooling units move cool air from the cabinet front

to the rear mounted switches to eliminate heat related switch failures.

Designed to eliminate compounded heating of intake air for

Cisco 6509 and Nexus 7018 switches that are arranged in a

row layout, the GSA9 directs the hot air into the hot aisle where it

can be properly handled. With no active components, the GSA9

unit elegantly redirects the heated air away from the systems that

depend on a cool air supply to run reliably and effi ciently. This

simple design is the perfect answer to protect the high dollar

investment.
