What kind of OS does Oracle ZFS use?
To deliver high performance and advanced data services, the Oracle ZFS Storage Appliance uses a combination of standard enterprise-grade hardware and a unique, storage-optimized operating system (OS) based on the Oracle Solaris kernel with Oracle’s ZFS file system at its core.
How is data integrity achieved in ZFS file system?
Within ZFS, data integrity is achieved by using a Fletcher-based checksum or a SHA-256 hash throughout the file system tree. Each block of data is checksummed and the checksum value is then saved in the pointer to that block—rather than at the actual block itself. Next, the block pointer is checksummed, with the value being saved at its pointer.
