- cascade
The transfer of statistics from the Node Management Agent
(NMA) on each of the peer nodes into the namespace of the master node. Cascading
provides the NMA of the master node with a view of the entire cluster.
- CGTP
(Carrier Grade Transport Protocol)
A reliable
transport protocol used for the transfer of IP packets over a cluster network.
CGTP duplicates data packets. It transmits the duplicate data packets on both
of the Ethernet networks. If one data packet is lost, the data packet sent
on the second network path is able to reach the destination address.
- CGTP address
The IP address of a CGTP interface.
See also CGTP interface.
- CGTP interface
An interface over which IP packets are transferred by using
the CGTP protocol.
See also CGTP
and virtual physical interface.
- cluster
A group of peer nodes that are connected by a network. To
be highly available, a cluster must have the following characteristics:
See also peer node, master node, and vice-master node.
- Cluster Membership Manager
See CMM.
- cluster network
The private network over which peer nodes communicate with
each other.
See also external network.
- cluster_nodes_table
A configuration file that stores the membership and configuration
information for all peer nodes in a cluster. A node must have an entry in
the cluster_nodes_table file to be part of a cluster.
There is a cluster_nodes_table on both master-eligible
nodes in the cluster.
- CMM
(Cluster Membership Manager)
A service that manages
the cluster membership. The CMM performs the following tasks:
Determines which nodes are members of the cluster
Assigns the roles and attributes of nodes
Detects the failure of nodes
Notifies clients of changes to the cluster
- CompactPCI
(Compact Peripheral Component Interconnect)
- CompactPSB
(CompactPCI Packet Switched Backplane)
- custom installation
Manual installation or installation using the nhinstall tool.
