Abstract
Systems and methods for providing input/output (I/O) determinism. An I/O instruction and at least one service level indicator are received, wherein the at least one service level indicator includes a required time for executing the I/O instruction. It is determined whether the I/O instruction can be executed on the storage within the required time. When it is not determined that the I/O instruction can be executed on the storage within the required time, a notification is sent.
Claims14
A method for providing input/output (I/O) determinism for a server hosting at least a remotely accessible storage, comprising:
- receiving an I/O instruction and at least one service level indicator from a client device, wherein the at least one service level indicator includes a required time for executing the I/O instruction;
- determining whether the I/O instruction can be executed on the storage within the required time, wherein determining whether the I/O instruction can be executed on the storage within the required time further comprises:
- determining a first latency of communication between the server and the client device;
- and
- determining a first execution time for executing the I/O instruction on the storage, wherein it is determined that the I/O instruction can be executed on the storage within the required time when a sum of the first latency and the first execution time is less than the required time;
- and
- sending, to the client device, a notification, when it is not determined that the I/O instruction can be executed on the storage within the required time.

A system for providing input/output (I/O) determinism, comprising:
- a storage;
- a processing circuitry;
- and
- a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to:
- receive an I/O instruction and at least one service level indicator from a client device, wherein the at least one service level indicator includes a required time for executing the I/O instruction;
- determine a first latency of communication between the system and the client device;
- determine a first execution time for executing the I/O instruction on the storage;
- determine whether the I/O instruction can be executed on the storage within the required time, wherein it is determined that the I/O instruction can be executed on the storage within the required time when a sum of the first latency and the first execution time is less than the required time;
- and
- send, to the client device, a notification, when it is not determined that the I/O instruction can be executed on the storage within the required time.
7 more elements
A method for providing input/output (I/O) determinism for a server hosting at least a storage, the server including a processing circuitry, comprising:
- sending, by the processing circuitry to the storage, an I/O instruction and at least one service level indicator, wherein the at least one service level indicator includes a required time for executing the I/O instruction;
- determining, by the storage, whether the I/O instruction can be executed on the storage within the required time;
- and
- sending, to the processing circuitry by the storage, a notification, when it is not determined that the I/O instruction can be executed on the storage within the required time;
- sending the I/O instruction to another server including at least one other storage, wherein the I/O instruction is sent to the other server when the I/O instruction can be executed on the at least one other storage within the required time;
- determining a latency of communication between the server and the other server;
- determining an execution time for executing the I/O instruction on the at least one other storage, wherein the I/O instruction can be executed on the at least one other storage within the required time when a sum of the determined latency and the determined execution time is less than the required time;
- and
- sending, to the at least one other storage, the I/O instruction for execution, when it is determined that the I/O instruction can be executed on the at least one other storage within the required time.

- determine a latency of communication between the server and the other server;
- determine an execution time for executing the I/O instruction on the at least one other storage, wherein the I/O instruction can be executed on the at least one other storage within the required time when a sum of the determined latency and the determined execution time is less than the required time;
- and
- send, to the at least one other storage, the I/O instruction for execution, when it is determined that the I/O instruction can be executed on the at least one other storage within the required time.
