Target Code


EMC Isilon recommends the following versions of OneFS as Target Code. A OneFS release is designated as Target Code after it  satisfies specific criteria, which includes production time in the field, deployments across all support node platforms, and other  quality metrics. To ensure that your clusters are running the most stable and reliable version of OneFS, upgrade to the latest  Target Code available for the OneFS family that meets your business needs.
