Benchmarking an 18 Terabyte YugabyteDB Cluster with High Density Data Nodes

YugabyteDB has successfully tested a highly dense cluster configuration where each node stores up to 4.5 TB of data, exceeding the recommended limit for DataStax Enterprise-compatible databases like Cassandra. The cluster was built on general purpose SSDs with lesser RAM than previously used high-end instance types, and it achieved high performance metrics, including 19K reads/sec across four nodes at 1.3ms latency, and 20-25K write IOPS at about 3-4ms latency. The cluster demonstrated reliable and rapid scaling capabilities when adding a new node to the existing cluster, with the new node becoming operational within hours despite handling large amounts of data from the other four nodes. This achievement showcases YugabyteDB's ability to handle high data density while maintaining performance and reliability, making it an attractive option for organizations seeking cost savings through optimized database configurations.
