Cloud storage device implementing composite zoned namespace architecture

A method comprising:

• receiving, with a cloud storage device, data and a command from a host application to write the data to a corresponding zone of a first storage device of a plurality of storage devices;
• initializing, with the cloud storage device, a buffer in response to receiving the data;
• storing, with the cloud storage device, the data in the buffer that is initialized;
• determining, with the cloud storage device, one or more parameters in response to receiving the command;
• determining, with the cloud storage device, whether the command is error-free based on the one or more parameters;
• and
• writing, with the cloud storage device, the data from the buffer into the corresponding zone in response to determining that the command is error-free,
• wherein writing the data into the corresponding zone includes:
• determining that one or more logical block addresses (LBAs) have not been received;
• in response to determining that the one or more LBAs have not been received,
• checking whether an I/O wait timer has expired, and
• in response to determining that the I/O wait timer has expired:
• discarding the command, and
• providing an LBA error message to the host application.

A non-transitory computer-readable medium comprising instructions that, when executed by a cloud storage device, causes the cloud storage device to perform a set of operations comprising:

• receiving data and a command from a host application to write the data to a corresponding zone of a first storage device of a plurality of storage devices;
• initializing a buffer in response to receiving the data;
• storing the data in the buffer that is initialized;
• determining one or more parameters in response to receiving the command;
• determining whether the command is error-free based on the one or more parameters;
• and
• writing the data from the buffer into the corresponding zone in response to determining that the command is error-free,
• wherein writing the data into the corresponding zone includes:
• checking whether one or more logical block addresses (LBAs) have been received;
• in response to determining that the one or more LBAs have been received,
• creating a batch of the one or more LBAs, and
• submitting the batch and the command to the first storage device;
• and
• in response to determining that the one or more LBAs have not been received,
• checking whether an I/O wait timer has expired, and
• in response to determining that the I/O wait timer has expired:
• discarding the command, and
• providing an LBA error message to the host application.
