CTS Lite Device Test
Power Efficiency Measurement
SNIA Emerald Device 1.0
CTS Lite Device
CTS Lite Device test is a single seat, air-gapped, annual license for automated Device Level power efficiency measurement. CTS Lite Device tests are released in annual test versions. Past test versions are archived and available for download, re-test & comparison for the term of a valid license.
Storage Device
CTS Lite Device test is designed to test storage at the individual device level. The CTS Lite Device test is the test software required by the SNIA Emerald Device specification.
Power Efficiency
CTS Lite Device test measures the power efficiency of storage devices expressed in IOPS/W, MiB/s/W and GB/W while running Green Storage industry standard workloads. Quarch power analysis module (PAM) data is aggregated with CTS Lite Device test IO performance data and presented in automated html test reports.
SNIA Emerald System
The SNIA Emerald System specification sets forth the requirements for power efficiency measurement of datacenter system level storage. The Emerald 4.0 tests and workloads have been incorporated into ISO 24091 which is used by the US EPA, EU Lot 9 and the Japan Top Runner specifications. The under development SNIA Emerald System 5.0 will require the use of CTS Lite test software for system level power efficiency measurement of block IO LUNS.
SNIA Emerald Device
The SNIA Emerald Device specification sets forth the requirements for power efficiency measurement of individual storage devices. CTS Lite is the workload generator and software specified in the SNIA Emerald Device 1.0. The under development SNIA Emerald Device 1.0 will require the use of CTS Lite test software for system level power efficiency measurement of individual storage devices.
