The performance management software products allow you to monitor and tune storage system performance to improve and optimize storage utilization and storage system performance. Performance Monitor provides an intuitive, graphical interface to assist with performance configuration planning, workload balancing, and analyzing and optimizing storage system performance. Virtual Partition Manager allows you to create multiple virtual cache memories called cache logical partitions (CLPRs), each allocated to different hosts, to prevent contention for cache memory and improve I/O performance. Using Server Priority Manager you can designate prioritized ports and non-prioritized ports and set upper limits and thresholds for the I/O activity of these ports to prioritize I/O operations to host servers requiring high throughput and prevent low-priority activities from negatively impacting high-priority activities.

Virtual Partition Manager
Your storage system can connect to multiple hosts and can be shared by multiple users, which can result in conflicts among users. For example, if a host issues many I/O requests or reads or writes a large amount of data, the I/O performance of other hosts may be affected. Virtual Partition Manager allows you to create multiple virtual cache memories called cache logical partitions (CLPRs), each allocated to different hosts, to prevent contention for cache memory and improve I/O performance.
