X-Ray Four Corners, a simple and quick measure for burst performance

I/O bursts are common in database workloads. How does an HCI architecture handle short workload burts?

This simple X-Ray test, four corners microbenchmark can quickly simulate the workloads of different I/O types such as 8k random reads, 1m sequential reads, 8k random writes and 1m sequential writes in a sequence with 1 minute duration each. This can demonstrate how an HCI architecture is able to handle short 1 minute bursts in IOPS and throughput.
