Detailed Description

The structure of a slice command.

This structure can split into 4 parts:

Todo:
  • address: The logical address of the underlying slice command.

  • request type:

    As described in the structure of request pool REQ_POOL, this structure is used for distinguishing the type of requests.

  • request info
  • relation between requests:
