Resilient File System

Microsoft Windows Server 2012 introduced the new Resilient File System (ReFS). ReFS has built-in integrity checks and error correction, is highly scalable, and supports native tier optimizations. If Exchange is deployed with ReFS, the data integrity features must be disabled. ReFS is supported only on volumes that house database files, log files, or content index files.

When ReFS data integrity features are enabled, they protect data that is stored on basic disks, or JBODs. However, HPE does not recommend using ReFS for HPE Nimble Storage arrays, which have built-in data protection and other enhancements such as adaptive flash, inline compression, replication, and deduplication.
