CES features

To successfully use Cluster Export Services (CES), you must consider function prerequisites, setup and configuration, failover/failback policies, and other management and administration requirements.

CES cluster setup
You can set up a Cluster Export Services (CES) environment within a GPFS cluster.
CES network configuration
Cluster Export Services (CES) IP addresses are used to export data via the NFS, SMB, and Object protocols. File and Object clients use the public IPs to access data on GPFS file systems.
CES address failover and distribution policies
When a Cluster Export Services (CES) node leaves the GPFS cluster, any CES IP addresses that are assigned to that node are moved to CES nodes still within the cluster. Additionally, certain error conditions and administrative operations can cause a node to release its addresses to be reassigned to other nodes.
CES protocol management
Cluster Export Services (CES) protocols (NFS, SMB, and Object) are enabled or disabled with the mmces command.
CES management and administration
Cluster Export Services (CES) nodes can be suspended for maintenance reasons with the mmces command.
