Storage server forsecure and performant execution of user code in a data center storage

A method executed by at least one storage server for a data center, the method comprising:

• obtaining a data request, which indicates target data and a user-defined code;
• obtaining the target data by using a storage software of the at least one storage server;
• executing the user-defined code in an isolated execution environment using the target data as an input, wherein the execution environment is separated from the storage software;
• obtaining a result of executing the user-defined code as an output related to the data request;
• wherein the executing the user-defined code further comprises:
• determining one or more idle processors among at least one processor of the at least one storage server;
• executing the user-defined code by using the one or more idle processors;
• and
• wherein before determining the one or more idle processors, the method further comprises storing the data request in a queue, and during or after determining the one or more idle processors, the method further comprises picking up the data request from the queue.

A method for a system, wherein the system comprise at least one storage server and at least one of a compute server and a frontend server, wherein the at least one of the compute server and the frontend server is connected to the at least one storage server, and the method comprises:

• providing, by the at least one of the compute server and the frontend server, a data request to the at least one storage server;
• obtaining, by the at least one storage server, the data request, which indicates target data and a user-defined code;
• obtaining the target data by using a storage software of the at least one storage server;
• executing, by the at least one storage server, the user-defined code in an isolated execution environment using the target data as an input, wherein the execution environment is separated from the storage software;
• obtaining, by the at least one storage server, a result of executing the user-defined code as an output related to the data request;
• wherein the executing the user-defined code further comprises:
• determining one or more idle processors among at least one processor of the at least one storage server;
• executing the user-defined code by using the one or more idle processors;
• and
• wherein before determining the one or more idle processors, the method further comprises storing the data request in a queue, and during or after determining the one or more idle processors, the method further comprises picking up the data request from the queue.
