Using the SPC Benchmark-1 to determine price-performance ratios for a number of storage systems, the benchmark delivered results that demonstrate a 1.9 X advantage for the Sun Storage 6180 (8Gb) array over the IBM DS5020, as reported in a Sun BestPerf blog.

Further findings show that the Sun Storage 6180 array is more than 3.1 times better in price-performance compared to the NetApp FAS3040 system as measured by the SPC-1 benchmark.

In addition, the Sun Storage 6180 array beat the Hitachi 2100 system by 34% in price-performance on the SPC-1 benchmark, and the SPC-1 benchmark revealed that the Sun Storage 6180 array has 16% better IOPS/disk drive performance than the Hitachi 2100.

The SPC Benchmark-1 results also revealed that the Sun Storage 6180 array delivers 50% more SPC-1 IOPS than the previous generation Sun Storage 6140 array and the IBM DS4700 on the SPC-1 benchmark.

The blog describes SPC-1 as having an I/O workload that is characterized by predominately random I/O operations as typified by multi-user OLTP, database, and email servers environments. SPC-1 uses a highly efficient multi-threaded workload generator to thoroughly analyze direct attach or network storage subsystems.

Testing the same storage arrays (Sun Storage 6180 8 Gb and IBM DS 5020) on the SPC Benchmark-2 produced the following results, as reported in the Sun BestPerf blog:

• The Sun Storage 6180 array outperforms the IBM DS5020 system by 62% in price-performance for SPC-2 benchmark using RAID 5 data protection.

• The Sun Storage 6180 array outperforms the IBM DS5020 system by 64% in price-performance for SPC-2 benchmark using RAID 6 data protection.

• The Sun Storage 6180 array is over 50% faster than the previous generation systems, the Sun Storage 6140 array and IBM DS4700, on the SPC-2 benchmark using RAID 5 data protection

The blog notes that the SPC Benchmark-2 (SPC-2) is a series of related benchmark performance tests that simulate the sequential component of demands placed upon on-line, non-volatile storage in server class computer systems. SPC-2 provides measurements in support of real world environments characterized by large numbers of concurrent sequential transfer; demanding data rate requirements, including requirements for real time processing; diverse application techniques for sequential processing; substantial storage capacity requirements; and data persistence requirements to ensure preservation of data without corruption or loss.
