Zettabyte Reliability with Flexible End-to-end Data Integrity

In this paper, the authors introduce flexible end-to-end data integrity for storage systems, which enables each component along the I/O path (e.g., memory, disk) to alter its protection scheme to meet the performance and reliability demands of the system. They apply this new concept to Zettabyte File System (ZFS) and build Zettabyte-Reliable ZFS (Z2FS). Z2FS provides dynamical tradeoffs between performance and protection and offers Zettabyte Reliability, which is one undetected corruption per Zettabyte of data read.
