Five Green Data Center Solutions with High ROI
|

Study after study is showing the huge efficiency gains from containing either the hot aisle, cold aisle or even both. Cool Shield is a
very adaptable and cost effective solution for aisle containment. The versatile mounting system can be used for strip curtains, ceiling panels and/or doors. The mount can be
attached to the drop ceiling, cabinets or even to the floor.
All Cool Shield solutions feature fusible links which allow the
strips or panels to fall to the floor in the event of a fire.
This helps ensure that the aisle containment does not interfere
with the fire suppression system.
Cool Shield components are all cut to size and designed for easy
installation. A full aisle can be contained with no
disruption in a matter of a couple hours.

Sealing cable openings with KoldLok® products provide a cost-effective airflow and thermal management solution. KoldLok Raised Floor Grommets will
optimize your current cooling infrastructure,
mitigate equipment heat loads and
increase data center reliability.
Your IT equipment is generating more heat than ever and the cost to cool that equipment is increasing.
Electricity consumed by IT equipment is the primary driver of data center infrastructure costs. Based on measurements at multiple data centers, 50 - 80% of valuable conditioned air is not reaching the air intake of IT equipment due to unsealed cable openings. This lost air, known as bypass airflow, contributes to equipment hot spots, cooling unit inefficiencies, and increasing infrastructure costs. Sealing cable openings is an essential component of IT equipment reliability and availability. |

Cool Shield Plenum is
blanket like material designed to block or channel supply air in the raised floor space
or return air in the drop ceiling plenum. This can
significantly increase cooling efficiency by optimizing air flow
from and to CRAC units. The plenum rated material is easy
to install, even around obstructions.
Blocking supply air from unused areas of the data center and
channeling it to the cold aisles will increase the volume of air
available to perforated tiles. This can improve flow rates
in the cold aisle to improve efficiency and prevent hot spots.
Channeling air back to the CRAC units can increase the return
temperature which improves performance and prevents short
cycling. |

Blanking panels to cover unused RU spaces at the front of the cabinet protects cold aisle integrity.
If your data center is using hot aisle/cold aisle rack layouts, blanking
panels are the highest ROI solution you can use.
Typically, the cost is less than about $3 per RU but it can make
a huge difference in cooling effectiveness. They keep
valuable chilled air in the cold aisle while preventing hot air
from re-circulating from the back of the rack to the front
server intake.
There are several sizes and types of blanking panels ranging from steel,
molded plastic to PVC strip material. Many panels snap in
and out to make installation quick and easy. |

Prevent Air Mixing of Cold and Hot Aisles |
|
If air can pass through open rack spaces, the cold aisle/hot aisle concept loses effectiveness. Blanking panels are a simple but effective way to prevent air mixing. |

There are numerous solutions for making a positive change in data center cooling efficiency. However, it is not always obvious which solutions will be most helpful. In fact, because of the dynamic nature of air flows, it is possible to cause more problems with an intended solution.
Our CoolAudit service uses detailed information gathered from
your data center to create a computer model. We then use
CFD software to create temperature, air flow and pressure maps.
This will offer clues to the root cause of cooling problems.
We then simulate fixes one at a time to ensure we are not
adversely affecting other areas of the room. The result is
a report which reviews the current status and offers recommended
steps for improving efficiency using non-intrusive solutions. |

CoolAudit Uses CFD Software to Test Solutions |
|
CFD software is useful tool for finding the source of cooling problems. It is also invaluable for testing modifications to ensure they are
not only effective for the targeted issue but that the fix doesn't cause other unforeseen problems. |
