Mixed database workloads such as online transaction processing (OLTP) and decision support system (DSS) workloads have traditionally been difficult to manage on the same infrastructure. Each of these workloads places different demands on the storage system. The storage system cannot be tuned for one workload or the other; instead, it must support both database loads at performance levels that meet service level agreements (SLAs). The PowerMax 2000 with NVM Express (NVMe) flash drives introduces improvements in performance and parallelism that provide an ideal match for mixed database workloads. NVMe flash drives offer increased speed and the ability to service more requests in parallel.
