Efficient Resource Utilization in Data Centers

A system comprising:

• resources of a distributed system;
• and
• a computer processor in communication with the resources, the computer processor:
• identifying high-availability jobs and low-availability jobs that demand usage of the resources;
• determining a first quota of the resources available to low-availability jobs as a quantity of the resources available during normal operations;
• determining a second quota of the resources available to high-availability jobs as a quantity of the resources available during normal operations minus a quantity of the resources lost due to a tolerated event;
• executing the jobs on the resources of the distributed system;
• and
• constraining a total usage of the resources by both the high-availability jobs and the low-availability jobs to the quantity of the resources available during normal operations.

A method comprising:

• identifying high-availability jobs and low-availability jobs that demand usage of resources of a distributed system;
• determining a first quota of the resources available to low-availability jobs as a quantity of the resources available during normal operations;
• determining a second quota of the resources available to high-availability jobs based on a resource type, wherein:
• for storage capacity resources, the second quota of the resources available to high-availability jobs is the quantity of the resources available during normal operations;
• for storage bandwidth resources, the second quota of the resources available to high-availability jobs is the quantity of the resources available during normal operations minus a quantity of the resources lost due to a tolerated event and minus an increased quantity of the remaining resources needed due to the tolerated event;
• and
• for non-storage resource resources, the second quota of the resources available to high-availability jobs is the quantity of the resources available during normal operations minus the quantity of the resources lost due to a tolerated event;
• executing the jobs on the resources of the distributed system;
• and
• constraining a total usage of the resources by both the high-availability jobs and the low-availability jobs to the quantity of the resources available during normal operations.
