Efficient resource utilization in data centers

A method comprising:

• identifying, using a data processing device, high-availability jobs and low-availability jobs that demand usage of data storage resources of a distributed storage system, the data storage resources having spindles;
• determining, using the data processing device, a spindle quota for the high-availability jobs;
• determining, using the data processing device, a spindle quota for the low-availability jobs;
• and
• redistributing, using the data processing device, at least a portion of the spindle quota associated with the low-availability jobs to the high-availability jobs during a failure event.

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 resources of a distributed system, the high-availability jobs have a higher execution priority than the low-availability jobs;
• allocating resource usage to the jobs;
• determining a first load of the jobs on resources available during a failure event;
• determining a second load of the jobs on resources lost during the failure event;
• determining a scaled third load of the jobs on the resources available during the failure event based on the first and second loads;
• and
• reallocating resource usage assigned to the low-availability jobs to the high-availability jobs during the failure event, the reallocation associated with the scaled third load of the jobs.
