| Research Abstract |
I have developed a scheme that dynamically relocate data blocks in a heterogeneous SAN (Storage Area Network) environment. In order to allocate data blocks to the most suitable storage node according to access frequency of the blocks, each node has to exchange the access information in a short period. Such extra network traffic introduces high overhead, and may cause traffic jam. In this scheme, the access information can be attached to a small-sized packet. This method can exchange fresh and detailed information about dynamic relocation of data at low overhead.
