Benchmark Description

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 transfers.
  • Demanding data rate requirements, including requirements for real time processing.
  • Diverse application techniques for sequential processing.
  • Substantial storage capacity requirements.
  • Data persistence requirements to ensure preservation of data without corruption or loss.
Key Points and Best Practices

  • This benchmark was performed using RAID 5 and RAID 6 protection.

  • The controller stripe size was set to 512k.

  • No volume manager was used.
