Abstract: We propose an exclusive data allocation method and evaluate the storage I/O response time with this method between a solid state drive (SSD) for a tiered volume and an SSD for cache in a storage system that uses both an SSD and hard disk drive (HDD). With the proposed method, the SSD cache function with exclusive data allocation caches only data allocated on the HDD tier. This enables more data to be allocated on the SSD, which reduces storage I/O response time. The simulation results show that the proposed method reduces the storage I/O response time in high I/O locality workload or low I/O locality workload with large SSD capacity. It also reduces the storage I/O response time by up to 23% compared to a combination of SSD/HDD volume tiering and SSD cache methods with no exclusive data allocation.
