The first of a two-part series on data center capacity management.

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.
