Maximise Efficiency with Targeted InRow Cooling Solutions. Modular solution features variable speed fan technology

"By 2011, in-rack and in-row cooling will emerge as the predominant cooling strategy for high-density equipment."
-Gartner

Virtualisation, server consolidation, thin clients, and high-density equipment are raising temperatures in data centres and turning up the heat on managers to find effective cooling solutions. The issues are significant:
Data centres with a traditional raised floor cannot get enough air to the high-density racks.

•Virtualised environments lead to increased load moving and switching, which leads to dynamic heat and hot spots.

•Utility costs continue to surge.

•Floor space is cramped, and budgets are tight.

•Technology is being deployed in spaces never intended to be IT environments.There is growing awareness of the need for innovative cooling solutions in today's data centres.

According to Gartner, by 2011, in-rack and in-row cooling will emerge as the predominant cooling strategy for high-density equipment. Five years ago most data centre and facilities managers did not know what their cooling requirements would be like today, and they cannot predict what those requirements will be five years from now. The way to be positioned for increasingly virtualised and high-density IT environments is to adopt a high-efficiency modular cooling solution with variable fan speed technology and management control at the rack and row level.

Exclusive variable fan speed technology
APC by Schneider Electric InRow cooling units have been designed to closely couple cooling with the heat load, preventing exhaust air from recirculating into sensitive IT equipment. When you reduce the distance between the cooling source and the heat load, air mixing is minimised (thus avoiding hot spots) and availability is improved.

InRow models are the only cooling units with Active Response Controls, which dynamically control the variable fan speeds to match the cooling capacity up or down to the variable heat load. InRow units right-size themselves and actively respond to any thermal change in the row. As heat loads dynamically move around the room in a virtualised environment, the cooling units automatically adjust-so you avoid the inefficiency of overcooling the entire room to handle a local issue.

Local and remote monitoring capabilities provide pinpoint control. Sensors monitor the temperature at the rack and row level, so you get up-to-the-second information on exactly where within the room the heat issues are at any given time. Localised hot spots can no longer "hide" from room-level sensors.

Deploy in a zone or on its own
APC InRow cooling units allow you to react quickly to changing cooling requirements. Adopting a virtualised environment or increasing the power density (and therefore the heat density) doesn't mean you have to rip out your existing infrastructure and start from scratch. Whether you're adding a new system or overlaying a high-density "island" as a dedicated zone within the existing data centre, the modular "pay as you grow" design of InRow cooling units are the most energy-efficient method of cooling rack-based equipment today.

InfraStruXure High Density (HD) Ready architecture
InfraStruXure HD-Ready systems right-size your virtualised environment by design. Our one-of-a-kind InRow cooling solution with optional hot aisle containment neutralises heat at the source. The Symmetra PX 250/500's scalable UPS technology avoids wasteful oversizing. Groundbreaking management software pinpoints exactly where you have "stranded" capacity so you can put it to better use. The system's right-sized power and cooling enables you to maximise the benefits gained through virtualisation.

7 Principles of InfraStruXure High Density (HD) Ready Architecture:

1. Rack enclosures that are HD-Ready
2. Metered PDUs at the rack level
3. Temperature monitoring in the racks
4. Centralised monitoring software
5. Software to manage capacity and change
6. Efficient row-based cooling technology
7. UPS power that is flexible and scalable
