System and method for storing data using ethernet drives and ethernet open-channel drives

A system for storing data, comprising:

• one or more Ethernet drives configured to communicatively connect to a host device;
• and
• a controller in communication with the host device and the one or more Ethernet drives, configured to:
• receive a first write command from the host device, the first write command including a first set of one or more input parameters and a first set of one or more output parameters indicating one or more memory buffers in the host;
• determine a first drive among the one or more Ethernet drives using at least one of the one or more input parameters and a mapping table;
• translate the first write command into a second write command, the second write command including a second set of one or more output parameters indicating one or more memory buffers in the host device;
• and
• send the second write command to the first drive,
• wherein the first drive is configured to
• responsive to receiving the second write command, send a first remote data transfer instruction to the host device independent of the controller, the first remote data transfer instruction to cause the host device to read data from the one or more memory buffers indicated by the second set of one or more output parameters and to remotely write the read data from the one or more memory buffers to the first drive.

A method for reading stored data, comprising:

• receiving, by a controller of a storage system in communication with a host device and one or more Ethernet drives, a first read command from the host device, the first read command including a first set of one or more input parameters and a first set of one or more output parameters indicating one or more memory buffers in the host device;
• determining, by the controller, a first drive among one or more Ethernet drives in communication with the host device, using at least one of the one or more input parameters and a mapping table;
• translating, by the controller, the first read command into a second read command, the second read command including a second set of one or more output parameters indicating one or more memory buffers in the host device;
• sending, by the controller, the second read command to the first drive;
• and
• responsive to receiving the second read command, sending by the first drive a first remote data transfer instruction to the host device independent of the controller, the first remote data transfer instruction including stored data read from the first drive to cause the host device to write the stored data read from the first drive to the one or more memory buffers indicated by the second set of one or more output parameters.

A method for storing data, comprising:

• receiving, by a controller in communication with a host device and one or more Ethernet drives, a first write command from the host device, the first write command including a first set of one or more input parameters and a first set of one or more output parameters indicating one or more memory buffers in the host;
• determining, by the controller, a first drive among the one or more Ethernet drives in communication with the host device, using at least one of the one or more input parameters and a mapping table;
• translating, by the controller, the first write command into a second write command, the second write command including a second set of one or more output parameters indicating one or more memory buffers in the host device;
• sending, by the controller, the second write command to the first drive,
• responsive to receiving the second write command, sending by the controller a first remote data transfer instruction to the host device independent of the controller, the first remote data transfer instruction to cause the host device to read data from the one or more memory buffers indicated by the second set of one or more output parameters and to remotely write the read data from the one or more memory buffers to the first drive.

A method for garbage collection in a storage system, comprising:

• executing, by a controller of a storage system, a garbage collection command, the garbage collection command including a first drive identifier identifying a first drive among one or more Ethernet drives;
• allocating, by the controller, with the first drive identifier using a mapping table, a free block at a destination address in a destination drive among one or more Ethernet drives;
• identifying, by the controller, with the first drive identifier using the mapping table, a source address in the first drive;
• sending, by the controller, a move command to the first drive, the move command including the source address, the destination address, and the destination drive;
• responsive to receiving the move command, reading, by the first drive, data from the identified source address in the first drive;
• and
• sending, by the first drive, a program command to the destination drive and causing the destination drive to copy the data read from the identified source address to the free block at the destination address in the destination drive.
