Share files with Xsan in macOS Server
Xsan lets you share files over a storage area network (SAN). A storage area network is a way of connecting computers and storage devices so that the computers have fast, shared access to files while making it easy for administrators to expand storage capacity.
An Xsan SAN consists of:
Shared data volumes
RAID systems that provide storage space that’s protected against disk failure
At least one computer acting as a metadata controller that combines the RAID arrays and presents their storage to clients as one or more volumes that behave like local disks
Client computers that access storage in accordance with established permissions and quotas
Underlying Fibre Channel, Distributed LAN Client (DLC), and Ethernet networks
After you set up Xsan, you administer it using the Server app.
