Enhanced Hypervisor-based SSD Cache with Dynamic Cache Scanning and Allocation for Virtualized Cloud System
2015
International Journal of Networked and Distributed Computing (IJNDC)
Recently, SSD caching is widely studied for VM-based systems. In this paper we propose a novel hypervisor-based SSD caching scheme, employing a new metric to accurately determine the demand on SSD cache space of each VM. Computer simulation confirms that it substantially improves the accuracy of cache space allocation compared to the existing schemes. It also allows comparable hit ratio as the existing schemes with less amount of SSD cache for the VMs.
