1Overview

This document specifies the guidelines on how the SPEC SFS 2014 Benchmark is to be run for measuring and publicly reporting performance results. These rules have been established by the SPEC SFS subcommittee and approved by the SPEC Open Systems Steering Committee. They ensure that results generated with this suite are meaningful, comparable to other generated results, and are repeatable (with documentation covering factors pertinent to duplicating the results).


This document provides the rules to follow for all submitted, reported, published and publicly disclosed runs of the SPEC Solution File Server (SPEC SFS 2014) Benchmark according to the norms specified and approved by the SPEC SFS subcommittee. These run rules also form the basis for determining which server hardware and software features are allowed for benchmark execution and result publication.
This document should be considered the complete guide when addressing the issues of benchmark and file server configuration requirements for the correct execution of the benchmark. The only other documents that should be considered are potential clarifications or interpretations of these Run and Reporting Rules. These potential interpretations should only be accepted if they originate from and are approved by the SFS subcommittee.
These Run and Reporting Rules are meant to provide the standard by which customers can compare and contrast solution performance. It is the intent of the SFS subcommittee to set a reasonable standard for benchmark execution and disclosure of results so customers are presented with enough information about the disclosed configuration to potentially reproduce configurations and their corresponding results.
As a requirement of the license of the benchmark, these Run and Reporting Rules must be followed. If the user of the SPEC SFS 2014 benchmark suite does not adhere to the rules set forth herein, SPEC may choose to terminate the license with the user. Please refer to the SPEC SFS 2014 Benchmark license for complete details of the user’s responsibilities.
Per the SPEC license agreement, all results publicly disclosed must adhere to these Run and Reporting Rules.
The general philosophy behind the set of rules for benchmark execution is to ensure that benchmark results can be reproduced if desired:
1. All data published must be gathered from benchmark execution conducted according to the Run and Reporting Rules described in this chapter.

2. Benchmark execution must complete in its entirety and normally without benchmark failure or benchmark error messages.

3. The complete hardware, software, and network configuration used for the benchmark execution must be published. This includes any special server hardware, client hardware or software features.

4. Use of software features which invoke, generate or use software designed specifically for the benchmark is not allowed. Configuration options chosen for benchmark execution should be options that would be generally recommended for the customer.

5. The entire Solution under test (SUT), including all components and services, shall be generally available within 6 weeks of the first publication of the results. If the solution was not generally available on the date tested, the generally available solution’s performance must meet or exceed that of the solution tested for the initially reported performance. If the generally available solution does not meet the reported performance, the lower performing results from the generally available solution shall be published. However, lower results are acceptable if the margin of error for peak business metric is less than one percent (1%) and the margin of error for overall response time is less than five percent (5%)

Products are considered generally available if they can be ordered by ordinary customers and ship within a reasonable time frame. This time frame is a function of the product size and classification, and common practice. The availability of support and documentation for the products must coincide with the release of the products.

Hardware and software products must be generally available, as defined above, and still supported by their primary vendor.


In the disclosure, the submitting vendor must identify any SUT component that can no longer be ordered by ordinary customers.
