Use the Performance Acceleration Module to optimize the performance of your random read intensive workloads such as file services. The intelligent read cache was created so that you can reduce latency and improve I/O throughput without adding more fast-spinning disk drives.
Tune this Performance Acceleration Module to match your workload characteristics by using software settings. You can configure up to five modules as a unified 80GB read cache in the PCI Express slots of your storage controller.
Grow without straining your infrastructure, because the Performance Acceleration Module uses no rack space and 95% less power than a shelf of 15k RPM disk drives. You can use the module in place of one or more disk shelves for your storage workloads that are random read intensive.
Optimize the performance of your storage system without adding disk drives!
