1. gp3 disks with a baseline performance of 3000 IOPS and 125 MiB per second are used for control plane/etcd nodes because etcd is latency sensitive. gp3 volumes do not use burst performance.
|
|
2. Infra nodes are used to host Monitoring, Ingress, and Registry components to ensure they have enough resources to run at large scale.
|
|
3. Workload node is dedicated to run performance and scalability workload generators.
|
|
4. Larger disk size is used so that there is enough space to store the large amounts of data that is collected during the performance and scalability test run.
|
|
5. Cluster is scaled in iterations and performance and scalability tests are executed at the specified node counts.

1. Nodes are distributed between two logical control units (LCUs) to optimize disk I/O load of the control plane/etcd nodes as etcd is I/O intensive and latency sensitive. Etcd I/O demand should not interfere with other workloads.
|
|
2. Four compute nodes are used for the tests running several iterations with 100/250/500 pods at the same time. First, idling pods were used to evaluate if pods can be instanced. Next, a network and CPU demanding client/server workload were used to evaluate the stability of the system under stress. Client and server pods were pairwise deployed and each pair was spread over two compute nodes.
|
|
3. No separate workload node was used. The workload simulates a microservice workload between two compute nodes.
|
|
4. Physical number of processors used is six Integrated Facilities for Linux (IFLs).
|
|
5. Total physical memory used is 512 GiB.
