"GateSpeed"

The "GateSpeed" Performance Benchmarking Suite is one of three comprehensive “canned” test suites that are based on OakGate's many years of experience testing products from industry leading storage suppliers.

  • Measure basic performance
  • Measure performance under specific workloads
  • Examine performance when I/Os are capped
  • Examine performance under various entropy patterns

Basic Performance Test

Measures basic performance

  • Perform a Secure Erase or Format command
  • Precondition including a substantial number of large Write commands
  • Run for 5 + minutes
  • Generate data sets for both Sequential and Random access.
    • Data is collected in 4 dimensions with 4 individual loop algorithms. Any three parameters can be displayed in a single graph

Workload Performance Test

Measure performance under specific workloads

  • Basic performance parameters run with 4 LBA offset values (block, 4K, 8K, and 32K)
  • Generate 4 separate data sets
    • I/OPs and Latency as a function of I/O Size, R/W ratio, Queue Depth

I/O Capping Test

Examines the effect I/O capping on latency

  • Runs for 4 I/O sizes (block, 4K, 64K and 512K I/Os)
  • Examines I/O latency as a function of
    • I/O capping, Read/Write ratio, Queue depth

Entropy Test

Examines performance while varying the compressibility of the data for storage that uses compression algorithm

  • Run for 4 I/O sizes (block, 4K, 64K and 512K I/Os)
  • I/OPs and I/O latency as a function of
    • Data entropy, Read/Write ratio, Queue depth
