Dell Technologies and Intel recently created a testing environment to measure the performance of DataStax Enterprise running on Dell Technologies infrastructure. The goal of the DataStax Enterprise performance test was to determine the performance of Apache Cassandra running on both Red Hat OpenShift and VMware Tanzu in the following scenarios:
- Write-intensive—Heavy write/update patterns with 10 percent reads, 90 percent writes/updates that focus on high-capacity storage and loose service-level agreement (SLA) requirements. In this context, the SLA is the request latency.
- Read-intensive—Write once/read many patterns with 90 percent reads, 10 percent writes that focus on the 10 millisecond- to 20 millisecond-SLA range and medium throughput.
- Balanced read/write—A 50 percent read/50 percent write pattern that focuses on the 10 millisecond- to 20 millisecond-SLA range with medium throughput.
- High performance—Focuses on sub-1 millisecond SLAs and high throughput using Intel Optane persistent memory (PMem). This test was only run on the Red Hat OpenShift configuration because VMware Tanzu does not support Intel Optane PMem. Other VMware options that support Intel Optane PMem are available from VMware and Dell Technologies.
For both Red Hat OpenShift and VMware Tanzu, the engineers defined a five-node configuration based on a common Dell EMC PowerEdge server platform as the test environment and recommended architecture. The Dell EMC PowerEdge R640 server provided a flexible server platform that could be configured with different CPU and storage options to meet the needs of all of the scenarios described above.
While this configuration met our test-environment needs, your specific business workloads might require a different configuration. Dell Technologies can help you with sizing assistance and server choices that meet your workload demands.
