Abstract

Systems and methods for processing copy commands are disclosed. A first controller of the storage device receives a copy command from a host via a first queue. The storage device generates, based on the copy command, a read command and a write command, and submits the read and write commands to a second controller of the storage device via a second queue. The second controller retrieves and processes the read and write commands from the second queue. The storage device reads, based on the processing of the read command, data stored in a first location of a storage media associated with a source address, and writes the data to a second location of the storage media associated with a destination address. The first controller transmits a signal to the host for indicating completion of the copy command.

Claims20

Dependent claims

A method for processing a copy command from a host to a storage device, the method comprising:

receiving, by a first controller of the storage device, the copy command from the host via a first queue, wherein the copy command includes a first source address and a first destination address;
generating, by the storage device, based on the copy command, a first read command and a first write command;
submitting, by the storage device, the first read command and the first write command to a second controller of the storage device via a second queue;
retrieving and processing, by the second controller, the first read command and the first write command from the second queue;
reading, by the storage device, based on the processing of the first read command, data stored in a first location of a storage media of the storage device associated with the first source address;
writing, by the storage device, based on the processing of the first write command, the data to a second location of the storage media associated with the first destination address;
and
transmitting, by the first controller, a signal to the host for indicating completion of the copy command.

5 more elements

A storage device comprising:

a storage media;
one or more processors coupled to the storage media, the one or more processors being configured to respectively:
receive, via a first controller and a first queue, a copy command from a host, wherein the copy command includes a first source address and a first destination address;
generate, based on the copy command, a first read command and a first write command;
submit the first read command and the first write command to a second controller via a second queue;
retrieve and process, via the second controller, the first read command and the first write command from the second queue;
read, based on the processing of the first read command, data stored in a first location of the storage media associated with the first source address;
write, based on the processing of the first write command, the data to a second location of the storage media associated with the first destination address;
and
transmit, via the first controller, a signal to the host for indicating completion of the copy command.
