4 Performance Benchmarks SPC Industry Standard Benchmarks SPC-1 emulates I/O patterns of typical On-Line Transaction Processing (OLTP) applications Primarily random data access with a sequential component 40% reads / 60% writes / 8KB average IO size Application examples - resource planning, order entry, , financial services, scheduling, reservations systems SPC-2 emulates applications that read and write large blocks of data in a sequential manner Consists of three workloads and a composite score that aggregates all of the workload results into a single metric Application examples - archival, backup, business intelligence, and video streaming OLTP Database Simulation Benchmarks Simulates IO done by OLTP applications. Similar to SPC-1. Do a mix of random reads and writes with cache hits and cache misses. DBO(Database Open): 70% read/30% write, 4KB IO s, 50% cache hit DB zos(database System Z): 75% read/25% write, 4KB IO s, 72% cache hit Sequential IO Large block sequential reads or writes to the storage server s drives. Similar to SPC-2. Corner benchmarks Perform just one type of IO pattern. Most applications combine a mix of different IO patterns. Cache Hits: 4KB random reads or writes to the storage server s cache. Cache Misses: 4KB random reads or writes to the storage server s drives. 4
