Implementing Cluster Export Services
Cluster Export Services (CES) provides highly available file and object services to a GPFS™ cluster by using Network File System (NFS), Object, or Server Message Block (SMB) protocols.
Note: This feature is available with IBM Spectrum Scale™ Standard
Edition or higher.
CES is an alternate approach to using a clustered Network File System (CNFS) to export GPFS file systems. For more information about CES and protocol configuration, see the Configuring the CES and protocol configuration.
