US 2019/0294373 A1 · STORAGE DEVICE MOUNTED ON NETWORK FABRIC AND QUEUE MANAGEMENT METHOD THEREOF

Abstract

A queue management method of a storage device which is connected to a network fabric and which includes a plurality of nonvolatile memory devices, includes receiving a write command and write data provided from a host through the network fabric, writing the write command to a command submission queue and writing the write data to a data submission queue, wherein the data submission queue is managed independently of the command submission queue, and executing the write command written to the command submission queue to write the write data written to the data submission queue to a first target device of the plurality of nonvolatile memory devices.

Dependent claims

A queue management method of a storage device which is connected to a network fabric, the storage device including a plurality of nonvolatile memory devices, the method comprising:

the storage device receiving a write command and write data provided from a host through the network fabric;
the storage device writing the write command to a command submission queue and writing the write data to a data submission queue;
the storage device managing the data submission queue independently of the command submission queue;
and
the storage device executing the write command written to the command submission queue to write the write data from the data submission queue to a first target device of the plurality of nonvolatile memory devices.

2 more elements

A storage device comprising:

a plurality of nonvolatile memory devices;
and
a storage controller configured to provide interfacing between the plurality of nonvolatile memory devices and a network fabric,
wherein the storage controller comprises
a host interface configured to provide the interfacing with the network fabric,
a memory configured to implement a queue of a single layer, and
a storage manager configured to manage the queue and to control the plurality of nonvolatile memory devices, wherein the storage manager is configured to implement and manage the queue in the memory, for managing a command and data transmitted from a host, and
wherein the queue of the single layer comprises
a command submission queue configured to hold a write command or a read command provided from the host,
a data submission queue configured to write hold data provided together with the write command, wherein the data submission queue is managed independently of the command submission queue, and
a completion queue configured to hold read data output from at least one of the plurality of nonvolatile memory devices in response to the read command.
