OPTIMIZING APACHE CASSANDRA™ AT SCALE SOLUTION BRIEF The Solution for Cassandra at Scale HGST has a long history of producing the largest and most reliable hard disk drives (HDDs) in the world. Couple those hard drives with the broad SanDisk-brand portfolio of flash storage technologies and you get a solution that enables Cassandra architects to achieve optimal Cassandra clusters. While modern multi-core servers allow parallel execution of multiple threads, Cassandra was not originally written to fully exploit them, which often leaves cores idling, waiting for data from storage. Ultimately, the low utilization causes server sprawl and wasteful spending of IT budgets. Apache Cassandra™ database About Apache Cassandra Avoiding Cassandra Server at scale can use both the Sprawl for Capacity Cassandra is an open source NoSQL cost-effective capacity of database written in Java and As described above, there are basically HGST-brand Ultrastar® helium specifically optimized to be scalable, two reasons to add servers to a cluster: hard drives and the density decentralized, fault tolerant, and, above to expand capacity or to increase and performance capabilities all, performant. It is used at some performance. Let’s examine how HGST of SanDisk®-brand solid- of the web’s largest properties and helium hard drives can help minimize state drives (SSDs) to fully throughout financial services and other the need for additional servers for exploit flash and modern industries as a repository of record with petabyte-scale capacities. servers and to provide
