A storage system comprising:
- a memory;
- and
- a controller configured to communicate with the memory and with a host comprising host memory, wherein the controller is further configured to:
- receive a write command from the host that is recognized by the storage system as a read host memory command;
- in response to receiving the write command, send an identification of a location in the host memory to the host;
- and
- receive, from the host, data that is stored in the location in the host memory.
A method comprising:
- performing the following in a storage system in communication with a host comprising host memory:
- receiving, from the host, at least one of the following:
- a command to write data to the storage system and a command to read data from the storage system;
- and
- instead of executing the command(s) received from the host, performing at least one of the following:
- writing data to the host memory and reading data from the host memory.
A storage system comprising:
- a memory;
- means for receiving a command from a host that establishes a communication channel between host memory in the host and the storage system;
- and
- means for, in response to receiving the command, writing data to and/or reading data from the host memory via the communication channel.
