Organizations are dealing with more data every day and need to be able to analyze that data quickly to make informed decisions. Many companies use the opensource NoSQL Apache Cassandra database system to handle large amounts of data. We tested three different hardware platforms to find out which delivered the best Apache Cassandra performance.

Using the Yahoo Cloud Serving Benchmark (YCSB) workload B to measure read-intensive Apache Cassandra performance of server solutions in virtualized environments, we tested a Dell PowerEdge C6620 server with a Dell PowerEdge RAID controller (PERC) 12 vs. two competitors. In one study, we compared the PowerEdge C6620 server solution against an HPE ProLiant XL170r Gen9 server with an HPE Smart Array P440ar controller. In another, we measured the performance of the PowerEdge C6620 server solution versus a previous-generation Dell PowerEdge C6520 server with a Dell PERC 11 controller.

In both studies, the PowerEdge C6620 server featuring the PERC 12 RAID controller delivered more YCSB operations per second. Moreover, the PowerEdge C6620 server featuring the Dell PERC 12 RAID controller delivered 2.1 times as many YCSB operations per second as the HPE solution—and had 60.2 percent lower application update latency.
