With growing costs of energy in their facilities, energy conservation seems to be on the top of the priority list for many data center operators.  According to Datacenter Journal and other industry sources, today’s data centers consume approximately 3% of global electricity and produce 200 million metric tons of CO₂.  And with the imminent growth of the Internet of Things (IoT), Big Data, social media and cloud computing, our reliance on these energy hogs shows no signs of subsiding.  While companies strategize new ways to reduce the astronomical cost required to power today’s data centers, they now also have to factor in a more long-term concern – their facilities’ impact on the environment.  One quick way to improve data center efficiency is through the optimization of environmental parameters, specifically Computer Room Air Conditioning (CRAC) / Computer Room Air Handler (CRAH) units.

There are several best practices that are often considered as an after thought to a sound capacity management strategy for today’s data center operations. Here are a few low- or no-cost ways to improve your approach to power and cooling capacity management. This is the first in a series of posts on data center capacity management.

Reporting
Do
Federate reporting out to both facilities and IT departments using a consistent data access, aggregation and reporting framework. Said framework should provide capacity measurements for each domain that are intuitive to the domain managers. For example, a server manager will want to see total, average server utilization. For servers, utilization is typically measure as a blend of processor capacity, Input/Output (I/O) and memory. By contrast, a facilities manager wants to see electrical and mechanical utilization of cooling and battery backup systems. For both domains, utilization can be expressed as a percentage of total system capacity. This reporting should be provided through a centralized portal that both facilities and IT managers can bookmark and set up notification preferences when capacity thresholds are exceeded. The best example of a high-level dashboard like this has been implemented by Dean Nelson at eBay. He has implemented a management framework that supports capacity management among others called Digital Service Efficiency (DSE). DSE is a free and open model that can be adopted by any organization today through the Data Center Pulse LinkedIn group.

Data centers require large amounts of energy to operate and we know that the push now is to reduce the use of data center energy usage — green initiatives, we hear about them everyday. Additional encouragement is coming from utilities throughout the United States in the form of data center energy efficiency rebates and incentives. As a matter of fact, I was at a recent data center function and was speaking to a person that runs the local utility’s program manager for commercial & industrial energy efficiency group and he said he literally has "tons of money he needs to give away in the form of data center energy incentives by the end of the year".
