In Mac OS X Lion 10.7, logical volume encryption (known as FileVault 2) was added to the operating system. This addition to the operating system in no way changed the logical structure of the file system. Apple's logical volume manager is known as Core Storage and its encryption at the volume level can apply to file systems other than HFS Plus.
Xsan (/ ˈ ɛ k s æ n /) is Apple Inc.'s storage area network (SAN) or clustered file system for macOS. Xsan enables multiple Mac desktop and Xserve systems to access shared block storage over a Fibre Channel network. With the Xsan file system installed, these computers can read and write to the same storage volume at the same time.
Hierarchical File System (HFS) is a proprietary file system developed by Apple Inc. for use in computer systems running Mac OS. Originally designed for use on floppy and hard disks , it can also be found on read-only media such as CD-ROMs .
Core Storage is a logical volume management system on macOS that was introduced by Apple to Mac OS X Lion. Core Storage is a layer between the disk partition and the file system.

The volume has a bitmap of used blocks. Other than this, there is no central file allocation table. A ProDOS 8 volume formatted by Apple's tools has a boot sector that supports booting both ProDOS and SOS depending on what computer it is booted on. Block 0 is the Apple II boot block and block 1 boots SOS.
