Data Center Energy Usage Assessment Service
PTS' Data Center Energy Usage Assessment Service provides data center operators with a spot measurement and calculation of the site's power usage effectiveness (PUE) and data center efficiency (DCE) ratios. The goal of this service is to assess the power utilization of the data center operations as the first step in determining whether energy efficiency improvements are achievable.
PTS' data center energy usage assessment service serves in
the 'assess' phase in the progression of the data center project process.
PUE is the ratio of total facility power supporting data center operations to the actual
power used by the IT infrastructure while DCE is the reciprocal calculation. The IT infrastructure
is the equipment used to manage, process, store, or route data within the computer room area(s).
It constitutes the critical load and includes all of the IT equipment, such as compute, storage,
and network equipment along with supplemental equipment such as KVM switches, monitors, and
workstations used to monitor or otherwise control the data center. The total facility power
supporting data center operations includes IT load plus all the support infrastructure loads including:
- Losses from power protection & distribution equipment including UPS, switchgear, generators, PDU, ATS, and batteries
- Power for cooling system components including chillers, computer room air conditioner units (CRACs), heat rejection equipment, pumps, cooling towers
- Power for miscellaneous non-UPS loads such as lighting
PTS' technicians will identify the total facility power supporting data center operations
as well as the actual power used by the IT infrastructure by collating the data from
various sources including inspecting equipment meters and/or by using power measurement
equipment to spot capture the power draw for all data center specific infrastructure
that cannot otherwise be determined.
The PUE and DCE ratios serve as a basis of comparison of the current data center power
usage versus industry standards. The assessment of these ratios can determine whether
the potential exists for substantial cost savings derived from improved power systems
Determine electrical load for both IT & support Infrastructure
Understand the actual power consumption of both the IT & supporting loads
