要約(英語): In a system using server SSD (Solid State Drive) cache and volume tiering functions, it is difficult to determine which data are to be placed on SSD tier on the basis of the number of I/Os. In this paper, we propose a volume tiering method cooperating with server SSD cache, which allocates storage SSD to read-intensive areas. We conduct an I/O simulation experiment using various I/O logs traced in a real environment to validate the proposed method. We show that the proposed method reduces the I/O average response time by up to 10% compared with the existing method.
