Can data locality help scale throughput?
X-Ray's throughput-scalability-random-reads and throughput-scalability-sequential-reads tests help answer the following:
AOS's data locality does not rely on network traffic for reads and able to scale reads 1x for each node without affecting other nodes.
X-Ray's throughput-scalability-random-reads and throughput-scalability-sequential-reads tests help answer the following:
- Can IOPS or throughput rate sustain over time?
- As number of nodes grow in cluster, can throughput or IOPS scale with it?
This test measures IOPS rate as it starts 8k random reads on all available nodes in 30 minutes interval. As workloads are started on subsequent nodes, X-Ray chart helps confirm if IOPS rate is sustained without much change.
This test measures I/O bandwidth as it starts 1m sequential reads on all available nodes in 30 minutes interval. As workloads are started on subsequent nodes, X-Ray chart helps confirm if bandwidth rate is sustained without much change.
