IBM Systems and Technology GroupzFS IntroductionzFS is a new z/OS UNIX file system. Advantages of zFS if compared with HFS:Significant performance enhancements can be achievedzFS is a logging file system. It logs metadata changes, so it can recover incase of a system crash (metadata-only journaling file system, like e.g. AIXJFS)Supports z/OS UNIX ACLs for fine-grain access authorizationClone-support for complete file systems (read-only point-in-time copies)More details can be found in the Redbook “z/OS Distributed File Service zSeriesFile System Implementation” (SG24-6580) and in the zFS admin guide(“Distributed File Service zSeries FileSystem Administration”, SC24-5989)35 z/OS RMF – The Latest and Greatest© 2003 IBM Corporation
