Virtual Partition Manager enables the logical partitioning of cache into independently managed virtual machines. The number of partitions and partition sizes can be adjusted nondisruptively while the storage system is in operation. These partitions can be allocated dynamically to utilize resources based on changes in business requirements by assigning different I/O workloads to different areas of cache.

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.
