SPC Specifications

SPC Benchmark 1 (SPC-1) Specification

The  SPC-1 version 3, retains the core capabilities and requirements of SPC-1 version 1, but includes support for data deduplication, and data compression, in addition to refining some of the workload attributes to bring the benchmark more in-line with modern storage system workloads. To assure a smooth transition to the new implementation of the SPC-1 workload, Test Sponsors are allowed to publish against either the version 1 or version 3 specification for the time being, though version 1 results are not comparable to version 3 results. 

The current and previous versions of the SPC-1 specification, which includes the SPC-1/E Energy Extension, are listed below. The "Effective Date" designates the date on which a given specifcaiton revision replaces its predecessor. Benchmark results may be released to be compliant with a version of the specification that has an "Effective Date" in the future.

Questions and comments concerning the specification may be sent to the SPC Administrator.
