Scheduler for handling io requests of different priorities

A data management and storage (DMS) system, comprising:

• peer DMS nodes in a node cluster;
• a distributed data store comprising local and cloud storage;
• and
• an IO request scheduler comprising at least one processor configured to perform operations in a method of scheduling IO requests, the operations comprising, at least:
• implementing a kernel scheduler to schedule a flow of IO requests in the DMS system;
• providing an adjustment layer to adjust the kernel scheduler based on an IO request prioritization;
• identifying a flow of IO requests;
• and
• implementing an IO request prioritization based on the adjustments made by the adjustment layer.

A non-transitory machine-readable medium comprising instructions which, when read by a machine of a data management and storage (DMS) system comprising peer DMS nodes in a node cluster and a distributed data store comprising local and cloud storage DMS system, cause the machine to implement operations in a method of scheduling IO requests, the operations comprising, at least:

• implementing a kernel scheduler to schedule a flow of IO requests in the DMS system;
• providing an adjustment layer to adjust the kernel scheduler based on an IO request prioritization;
• identifying a flow of IO requests;
• and
• implementing an IO request prioritization based on the adjustments made by the adjustment layer.
