Tests were conducted starting with four leaf nodes. The number of leaf nodes was increased gradually to six and eight to understand the variation in the PowerFlex performance. The workload was evaluated for each scenario and PowerFlex performance metrics were captured in the following table.
Table 4. Test scenarios
| No of leaf nodes | vCPUs per leaf node | Memory per leaf node | Read Max BW | Read Max IOPS |
Scenario -1 | 4 | 16 | 128 GB | 20.2 GB/s | 46.9 K |
Scenario -2 | 6 | 16 | 128 GB | 21.0 GB/s | 67.0 K |
Scenario -3 | 8 | 16 | 48 GB | 23.0 GB/s | 74.3 K |
Note: SingleStore does not recommend overcommitting the vCPUs for the leaf nodes.
