Abstract
A storage system includes a host and a storage device. The storage device includes a device memory. The host and the storage device communicate with one another through a CXL interface. The storage device receives an access request including a key value from the host, reads stream data from the device memory based on the key value and transmits the read stream data to the host.
Claims20
A storage system comprising:
- a host;
- and
- a storage device including a device memory,
- wherein the host and the storage device communicate with one another through a Compute Express Link (CXL) interface,
- wherein, in response to the storage device receiving an access request including a key value of a key from the host, the storage device reads stream data from the device memory and transmits the stream data to the host based on the key value synchronized between the host and the storage device according to a consistency mechanism of the CXL interface.
2 more elements
A storage system comprising:
- a storage device comprising a Compute Express Link (CXL) interface and a device memory that stores stream data;
- and
- a host connected to the CXL interface and configured to generate an access request including a data identifier,
- wherein the storage device reads the stream data from the device memory at a logic block address corresponding to the data identifier, and transmits the stream data to the host, and
- wherein the data identifier included in the access request is synchronized between the host and the storage device according to a consistency mechanism of the CXL interface.
2 more elements
A storage device comprising:
- a device CXL.mem protocol which receives stream data from a host;
- a device CXL.cache protocol which synchronizes the host with a key associated with the stream data in accordance with a consistency mechanism, and checks a key value of the key;
- and
- a device memory which stores the stream data together with the key value,
- wherein the storage device is configured to read and transmit the stream data to the host based on the key value synchronized between the host and the storage device.
