OneFS Job Engine primary functions

In the EMC Isilon OneFS® operating system, the Job Engine manages the scheduling, reporting, and the initiation of cluster protection and maintenance tasks. A significant benefit of the Job Engine is that it can adaptively manage maintenance jobs based on the amount of cluster resources available.

To ensure that your cluster is performing at optimal levels, follow these Job Engine best practices:

  • Schedule jobs to run during your cluster’s low usage hours.
  • When possible, use the default priority, impact, and scheduling settings for each job.
  • Ensure that the cluster, including individual node pools, is less than 90 percent full.
  • If the EMC Isilon SmartPools™ software module for resource management is licensed, ensure that default spillover setting is enabled.
  • Set up notification rules to alert you when the cluster begins to reach capacity thresholds and enable virtual hot spares (VHS) to reserve free space that’s needed in case you need to rebuild data if a disk failure occurs.
  • Do not disable the Snapshot Delete job.
  • Run the FSAnalyze job only if you are using InsightIQ. FSAnalyze creates data for the InsightIQ file system analytics tools and provide details about data properties and space usage with the OneFS file system.

Additional best practices can be found in the white paper, “EMC Isilon OneFS Job Engine.”

In the latest release of OneFS, several enhancements were made to the Job Engine. These enhancements were highlighted in our video, “Key New Features in EMC Isilon OneFS 7.1.” For more information about the enhanced Job Engine, read the white paper, “EMC Isilon OneFS Job Engine.”
