Storage zoning algorithm based on page migration for database with hybrid architecture
Mei Chen · Journal of Computer Applications · 2010
To effectively take advantage of high read speed of Solid-State Disk (SSD)'s and low cost of disk storage, under a mixed structure which is the coexistence of disk and SSD, a storage zoning algorithm based on page migration named SZA was proposed. A different calculating method of migration cost from NUMA was presented. The SZA algorithm was explained to choose corresponding storage medium based on the cost of migration. Migrating activity was processed on different workload of data. The simulation results show that the algorithm improves I/O performance effectively and the erasing times of flash have been reduced significantly.
