摘要： A storage controller includes a host interface configured to communicate with a host, a buffer memory configured to buffer data read from a non-volatile memory, a cache memory including a plurality of cache lines and configured to store the data in at least one of the plurality of cache lines, and a cache controller configured to manage a status bitmap. The status bitmap indicates priority information of the plurality of cache lines according to an operation corresponding to a request received from the host interface, and the cache controller is further configured to select a victim cache line, among the plurality of cache lines, to be replaced based on the status bitmap. In this case, the operation corresponding to the request corresponds to one of normal read, prefetch, read-after-read, and read-after-prefetch.

摘要： A computational network interface card (NIC) sharing a storage space with a memory expander thereof includes: a NIC memory including instructions; a NIC processor including a cache and electrically connected to the NIC memory; and a NIC configured to transmit data stored in the NIC memory or the cache to a network, wherein, the instructions are configured to cause the NIC processor to perform operations including: receiving a request to read or write metadata; and checking whether the requested metadata is stored in a local metadata cache of the computational NIC by sequentially checking whether the metadata is stored in the cache of the NIC processor, a cache of the NIC, the NIC memory, or the memory expander.
