STORAGE DEVICE SUPPORTING MULTI-HOST AND OPERATION METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17815720 titled 'STORAGE DEVICE SUPPORTING MULTI-HOST AND OPERATION METHOD THEREOF

Simplified Explanation

The disclosed patent application describes a method for operating a storage device under the control of a hypervisor. Here are the key points:

  • The method involves setting different threshold values for different hosts (first and second hosts) by the hypervisor.
  • Host commands from the first and second hosts are fetched sequentially and stored in an internal command queue.
  • When the number of commands fetched from the first host reaches the first threshold value, fetching from the first host is stopped.
  • Similarly, when the number of commands fetched from the second host reaches the second threshold value, fetching from the second host is stopped.

Potential applications of this technology:

  • This method can be applied in virtualized environments where multiple hosts are accessing a shared storage device.
  • It can be used in cloud computing environments where efficient resource allocation and management are crucial.
  • The method can be implemented in storage systems used in data centers or enterprise environments.

Problems solved by this technology:

  • The method helps in managing the workload of different hosts accessing the storage device.
  • It prevents one host from overwhelming the storage device with a large number of commands, ensuring fair access for all hosts.
  • The method optimizes the performance and resource utilization of the storage device in a multi-host environment.

Benefits of this technology:

  • Improved performance and responsiveness of the storage device by efficiently managing the command queue.
  • Fair resource allocation among multiple hosts, preventing any single host from monopolizing the storage device.
  • Enhanced scalability and flexibility in virtualized and cloud computing environments.


Original Abstract Submitted

Disclosed is an operation method of a storage device which includes setting a first threshold value for a first host and a second threshold value for a second host under control of a hypervisor, sequentially fetching host commands from the first and second hosts, storing the fetched host commands in an internal command queue, stopping fetching a host command from the first host when the number of first host commands fetched from the first host from among the host commands stored in the internal command queue reaches the first threshold value, and stopping fetching a host command from the second host when the number of second host commands fetched from the second host from among the host commands stored in the internal command queue reaches the second threshold value.
