SPC Specifications

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.

The current and previous versions of the SPC-2 specification, which includes the SPC-2/E Energy Extension, are listed below.

The SPC Policies and Procedures define the day-to-day operations for the Storage Performance Council. This is the definitive source of information about meetings, benchmark development, results publication, technical subcommittees, and all other operational aspects of the council. If you have any questions about this or any other administrative documents, please contact the executive director.

The Storage Performance Council was formed to provide benefit for the storage industry and its customers. As set forth in Article I of the Bylaws, it is the policy of the SPC to comply fully with the antitrust laws of the United States and similar foreign competition laws applicable to the SPC’s activities. It is expected that all company member
representatives involved in SPC activities, all SPC contractors, all SPC auditors, and any guests invited to participate in any SPC activity will take all measures necessary to comply with antitrust and competition laws.

This specification provides a uniform approach to the composition and pricing of storage configurations that may be applied to all SPC benchmarks. It is intended to:

• Clarify the basis for pricing-related calculations and disclosures;
• Define the terms and constraints related to pricing within SPC benchmark disclosures;
• Provide a uniform framework that can be applied to all SPC benchmarks without constraining the development of novel benchmark methodologies;
• Simplify the process of benchmark and benchmark extension development.
