Criteria for Component substitution when a measurement is not required. There are some cases where Component substitution can be proven through product documentation or other Component-level evaluation. The intent is to show that there is no adverse effect on the performance of the Priced Configuration. The certified TPC auditor and/or Pre-Publication Board has the option to require additional work beyond these rules. Licensed Compute Services Component Substitution When Licensed Compute Services Components substitution is allowed by the Benchmark Standard, it is permissible to substitute only the components that are specifically identified and only with units that are equal-to or greater-than those used in the Measured Configuration. Components are substituted on a 1 for 1 basis. This includes (if allowed by the Benchmark Standard) storage, networking, memory and/or the compute resources. Comment: It is expected that different Licensed Compute Service providers will have different terms and units for identifying, configuring, capacity and performance, but the underlying service level agreement as determined by the reported measurement must be upheld. Physically Acquired Middle-tier Component Substitution When middle-tier Component substitution is allowed by the Benchmark Standard, it is permissible to substitute the hard drive(s), the CPU, the cache, or the storage controller of a middle-tier system without measurement, provided that Components are substituted on a 1 for 1 basis. When upgrading CPU speed, the bus speed does not decrease. When upgrading CPU speed, the cache size is not reduced, at each cache level. The disk I/O levels are negligible (less than 5 I/Os per second), or disk controller is the same and the rules for storage substitution apply. When upgrading the cache, each cache size is not reduced. When upgrading the cache, the cache architecture isn’t changed. When increasing the number of cores, the new cores must have equal or faster clock speed and the cache size per is not reduced, at each cache level. When upgrading the processor, the processor architecture isn't changed. Physically Acquired Storage device substitution (HDD, SSD, Optical, …) If the following criteria are completely satisfied, an allowed storage device substitution can be done without additional measurement. The formatted capacity of the substitute device must be equal or greater than the substituted device. The substitute device must have the same interface type as the substituted device.
