Cooling Doesn’t Manage Itself
Of the primary components driving data center operations – IT assets, power, space and cooling – the first three command the lion’s share of attention. Schneider Electric (StruxureWare), Panduit (PIM), ABB (Decathalon), Nlyte, Emerson (Trellis) and others have created superb asset and power tracking systems. Using systems like these and others, companies can get a good idea as to where their assets are located, how to get power to them and even how to optimally manage them under changing conditions.
Less well understood and, I would argue, not understood at all, is how to get all the IT-generated heat out of the data center, and as efficiently as possible.
Some believe that efficient cooling can be “designed in,” as opposed to operationally managed, and that this is good enough.
On the day a new data center goes live the cooling will, no doubt, operate superbly. That is, right up until something changes – which could happen the next day, weeks or months later. Even the most efficiently designed data centers eventually operate inefficiently. At that point, your assets are at risk and you probably won’t even know it. Changes and follow-in inefficiencies are inevitable.
As well, efficiency by design only applies to new data centers. The vast majority of data centers operating today are aging. All of them have degraded with incremental cooling issues over time. IT changes, infrastructure updates, failures, essentially any and all physical data center changes or incidents, affect cooling in ways that may not be detected through traditional operations or “walk around” management.
Data center managers must manage their cooling infrastructure as dynamically and closely as they do their IT assets. The health of the cooling system directly impacts the health of those very same IT assets.
Further, cooling must be managed operationally. Beyond the cost savings of continually optimized efficiency, cooling management systems provide clearer insight into where to add capacity, redundancy, potential thermal problems, and areas of risk.
Data centers have grown beyond the point where they can be managed manually. It’s time stop treating cooling as the red-headed step-child of data centers. Cooling requires the same attention and sophisticated management systems that are in common use for IT assets. There’s no time to lose.
