Suggested protection

Based on the configuration of your Isilon cluster, OneFS automatically calculates the amount of protection that is recommended to maintain EMC Isilon's stringent data protection requirements.

OneFS includes a function to calculate the suggested protection for data to maintain a theoretical mean-time to data loss (MTTDL) of 5000 years. Suggested protection provides the optimal balance between data protection and storage efficiency on your cluster.

By configuring file pool policies, you can specify one of multiple requested protection settings for a single file, for subsets of files called file pools, or for all files on the cluster.

It is recommended that you do not specify a setting below suggested protection. OneFS periodically checks the protection level on the cluster, and alerts you if data falls below the recommended protection.
