SAN Volume Controller is designed to pool storage volumes from IBM and non-ibm storage systems into a single reservoir of capacity for centralized management. The SPC-1 Tested Storage Configuration used SVC Version 6.2 with CG8 storage engines. Each CG8 storage engine is equipped with 24 GB of cache and four 8 Gbps fibre channel ports. The storage engine also features the optional capability, not used to produce this SPC-1 Result, to add 10 Gbps Ethernet or SSD drives managed with EasyTier.

Clause The computed I/O Request Throughput of the Sustainability Test must be within 5% of the reported SPC-1 IOPS result. Clause The Average Response Time, as defined in Clause 5.1.1, will be computed and reported for the Sustainability Test Run and cannot exceed 30 milliseconds.

32 SPC-1 BENCHMARK EXECUTION RESULTS Page 32 of 80 PRIMARY METRICS TEST IOPS TEST PHASE Primary Metrics Test IOPS Test Phase Clause The IOPS Test Phase consists of one Test Run at the 100% load point with a Measurement Interval of ten (10) minutes. The IOPS Test Phase immediately follows the Sustainability Test Phase without any interruption or manual intervention. The IOPS Test Run generates the SPC-1 IOPS primary metric, which is computed as the I/O Request Throughput for the Measurement Interval of the IOPS Test Run. The Average Response Time is computed for the IOPS Test Run and cannot exceed 30 milliseconds. If the Average Response Time exceeds the 30 millisecond constraint, the measurement is invalid. Clause For the IOPS Test Phase the FDR shall contain: 1. I/O Request Throughput Distribution (data and graph). 2. A Response Time Frequency Distribution. 3. An Average Response Time Distribution. 4. The human readable Test Run Results File produced by the Workload Generator. 5. A listing or screen image of all input parameters supplied to the Workload Generator. 6. The total number of I/O Requests completed in the Measurement Interval as well as the number of I/O Requests with a Response Time less than or equal to 30 milliseconds and the number of I/O Requests with a Response Time greater than 30 milliseconds. SPC-1 Workload Generator Input Parameters The SPC-1 Workload Generator input parameters for the Sustainability, IOPS, Response Time Ramp, Repeatability, and Persistence Test Runs are documented in Appendix E: SPC-1 Workload Generator Input Parameters on Page 78.

37 SPC-1 BENCHMARK EXECUTION RESULTS Page 37 of 80 PRIMARY METRICS TEST RESPONSE TIME RAMP TEST PHASE Primary Metrics Test Response Time Ramp Test Phase Clause The Response Time Ramp Test Phase consists of five Test Runs, one each at 95%, 90%, 80%, 50%, and 10% of the load point (100%) used to generate the SPC-1 IOPS primary metric. Each of the five Test Runs has a Measurement Interval of ten (10) minutes. The Response Time Ramp Test Phase immediately follows the IOPS Test Phase without any interruption or manual intervention. The five Response Time Ramp Test Runs, in conjunction with the IOPS Test Run (100%), demonstrate the relationship between Average Response Time and I/O Request Throughput for the Tested Storage Configuration (TSC) as illustrated in the response time/throughput curve on page 14. In addition, the Average Response Time measured during the 10% Test Run is the value for the SPC-1 LRT metric. That value represents the Average Response Time of a lightly loaded TSC. Clause The following content shall appear in the FDR for the Response Time Ramp Phase: 1. A Response Time Ramp Distribution. 2. The human readable Test Run Results File produced by the Workload Generator for each Test Run within the Response Time Ramp Test Phase. 3. For the 10% Load Level Test Run (SPC-1 LRT metric) an Average Response Time Distribution. 4. A listing or screen image of all input parameters supplied to the Workload Generator. SPC-1 Workload Generator Input Parameters The SPC-1 Workload Generator input parameters for the Sustainability, IOPS, Response Time Ramp, Repeatability, and Persistence Test Runs are documented in Appendix E: SPC-1 Workload Generator Input Parameters on Page 78.
