A token represents the abstraction of data and is associated with a point-in-time (PIT) copy. A token is created by the SAN or SMB protocols by using protocol commands. Token Manager creates and copies tokens as requested by hosts for token-based copy-offload requests. In token-based copy-offload requests, the host sends an OFFLOAD READ command with the offsets to the source file or LUN. Token Manager creates a PIT copy of the offsets using sis-clone from source to PIT file and generates a token. This token is given to the host. The host then sends this token with the offsets to the destination file or LUN using an OFFLOAD WRITE cmd. Token Manager decodes the token, finds the data represented by the token and copies from the PIT file to the destination file or LUN. This completes a single token-based copy-offload request. This counter manager table tracks the number of token-based copy-offload requests received (both OFFLOAD READ and OFFLOAD WRITE), their sizes and their latencies. It also tracks various kind of errors that could have happened during token-based copy-offload requests.
