SPC certification is a SAN performance test benchmark for third-party evaluation. Which of the following statements is true about SPC certification scenarios?
- A. SPC-2 is used to test the SAN array performance in the OLPT, database, and email application scenarios.
- B. SPC-2 applies to scenarios where random small I/Os are quickly responded.
- C. SPC-2 applies to scenarios of sequential large I/O access.
- D. SPC-1 applies to scenarios of sequential large I/O access.
正解:C
解説:
SPC (Storage Performance Council) benchmarks are discussed in the *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)*: "SPC-1 tests random I/O workloads, such as OLTP, database, and email scenarios, while SPC-2 tests sequential large I/O access, such as video streaming or backups." Let's evaluate:
- Option A: Incorrect. SPC-2 is for sequential large I/Os, not random small I/Os (which is SPC-1).
- Option B: Incorrect. SPC-1 is for random I/Os, not sequential large I/Os.
- Option C: Correct. SPC-2 is designed for sequential large I/O access scenarios.
- Option D: Incorrect. SPC-1, not SPC-2, tests OLTP, database, and email scenarios.
Thus, option C is true.
