DYNAMIC CACHE PARTITION MANAGER IN HETEROGENEOUS VIRTUALIZATION CLOUD CACHE ENVIRONMENT

摘要

The system is disclosed. The present system may include a virtual machine server, and the virtual machine server may include a processor, a memory, and at least two virtual machines stored in the memory and executed by the processor. The virtual machine server may also include a virtual machine hypervisor that manages the operations of the virtual machine. The virtual machine server may also include a cache that may include at least one storage device. The Dynamic Cache Partition Manager (DCPM) can manage the partitioning of the cache into a performance guarantee area that can be partitioned into multiple areas and a spike buffer area. DCPM is a reusability statistic calculator that computes reusability statistics, a comparator that compares reusability statistics to a spike threshold, an access statistic calculator that computes access statistics, and a spike data identifier that identifies data in spike buffer regions that satisfy access statistics. , and a cache partitioner that repartitions the cache into a new performance guarantee zone and a second spike buffer zone for new timings. The second spike buffer zone is large enough to store the identified data.
