DEVICE FOR EFFICIENTLY MANAGING DATA TRANSFER BETWEEN TIERS FOR TRANSFERRING MASSIVE DATA

摘要

PURPOSE: A device for managing efficient data transfer between tiers is provided to transfer data from a low speed tier to a reserve space of a high speed tier, thereby maintaining hot data on the high speed tier.;CONSTITUTION: A first data storage device(106) is connected to a processor(102) and stores a reserve space table. A second data storage device(108) is connected to the processor. The first data storage device has high speed access time in comparison to the second data storage device. The reserve space table distinguishes a discrete unit of the first data storage device and a discrete unit of the second data storage device. The processor transfers data from the discrete unit of the second data storage device to the discrete unit of the first data storage device.;COPYRIGHT KIPO 2013;[Reference numerals] (102) Processor; (104) Memory; (106,108) Data
