A SCSI-to-IP cache storage system interconnects a host computing device or a storage unit to a switched packet network. The cache storage system includes a SCSI interface ( 40 ) that facilitates system communications with a host computing device or the storage unit, and an Ethernet interface ( 42 ) that allows the system to receive data from and send data to the Internet. The cache storage system further comprises a processing unit ( 44 ) that includes a processor ( 46 ), a memory ( 48 ) and a log disk ( 52 ) configured as a sequential access device. The log disk ( 52 ) caches data along with the memory ( 48 ) resident in the processing unit ( 44 ), wherein the log disk ( 52 ) and the memory ( 48 ) are configured as a two-level hierarchical cache. |
