Virtual Partition Manager operations

Parent Topic

• 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.

• Overview of Virtual Partition Manager
• System Option Modes for Virtual Partition Manager

  To provide greater flexibility, the storage systems have additional operational parameters called system option modes (SOMs) that allow you to tailor the storage system to your unique operating requirements. The SOMs are set on the service processor (SVP) by your service representative. Review the SOMs for your storage system, and work with your service representative to ensure that the appropriate SOMs for your operational environment are configured on your storage system.
