- Performance Management
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.

Server Priority Manager
Server Priority Manager allows you to set upper limits of the number of accesses from the server to storage system as well as the amount of data transfer. The upper limits are automatically disabled when the traffic between the server and storage system drops to user-defined levels. Server Priority Manager supports Fibre Channel and iSCSI ports connected to open-systems hosts.
