Abstract
A background process is configured to periodically scrub a boot storage of a storage controller to ensure operational correctness of the boot storage. One or more foreground processes store a system configuration data of the storage controller in the boot storage of the storage controller. The background process and the one or more foreground processes are executed to meet predetermined performance requirements for the background process and the one or more foreground processes.
Claims18
A method, comprising:
- configuring a background process to periodically scrub a boot storage of a storage controller to ensure operational correctness of the boot storage;
- storing, via one or more foreground processes, a system configuration data of the storage controller in the boot storage of the storage controller;
- and
- executing the background process and the one or more foreground processes to meet predetermined performance requirements for the background process and the one or more foreground processes, wherein the predetermined performance requirements include executing the background process at least once in a predetermined interval of time, and completing execution of each of the one or more foreground processes within a predetermined amount of time.
A method, comprising:
- configuring a background process to periodically scrub a boot storage of a storage controller to ensure operational correctness of the boot storage;
- storing, via one or more foreground processes, a system configuration data of the storage controller in the boot storage of the storage controller;
- and
- executing the background process and the one or more foreground processes to meet predetermined performance requirements for the background process and the one or more foreground processes, wherein in response to starting an execution of the background process if a number of executing foreground processes are greater than a predetermined threshold, then suspending some or all of the one or more foreground processes.
A system, comprising:
- a memory;
- and
- a processor coupled to the memory, wherein the processor performs operations, the operations performed by the processor comprising:
- configuring a background process to periodically scrub a boot storage to ensure operational correctness of the boot storage;
- storing, via one or more foreground processes, a system configuration data in the boot storage;
- and
- executing the background process and the one or more foreground processes to meet predetermined performance requirements for the background process and the one or more foreground processes, wherein the predetermined performance requirements include executing the background process at least once in a predetermined interval of time, and completing execution of each of the one or more foreground processes within a predetermined amount of time.
A system, comprising:
- a memory;
- and
- a processor coupled to the memory, wherein the processor performs operations, the operations performed by the processor comprising:
- configuring a background process to periodically scrub a boot storage to ensure operational correctness of the boot storage;
- storing, via one or more foreground processes, a system configuration data in the boot storage;
- and
- executing the background process and the one or more foreground processes to meet predetermined performance requirements for the background process and the one or more foreground processes, wherein in response to starting an execution of the background process if a number of executing foreground processes are greater than a predetermined threshold, then suspending some or all of the one or more foreground processes.
A computer program product, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform operations, the operations comprising:
