About
Microsoft Windows Clustering
Node Manager, Configuration Database Manager, Resource
Manager/Failover Manager, Event Communications Manager, Processor Global Update
Manager are all parts of the cluster membership and contribute to the health of
the other cluster systems. A collection of software, the Cluster Services provides
automatic recovery from failure and an ability to move workloads for planned maintenance
without downtime. It controls all aspects of cluster operations on a cluster system
and has closely related cooperating components:
These software groups together maintain the cluster configuration database, make
all resource/group management decisions and initiate appropriate actions, such as
startup, restart and failover.
The Event Processor connects the components of the Cluster Service and handles common
operations and controls Cluster Service initialization.
Communications Manager manages communications with all other nodes of the cluster,
while Global Update manager provides a global update service used by other components
within the Cluster Service.
Resource Monitor, while not a part of the Cluster Service, communicates with the
Cluster Service via Remote Procedure Calls (RPC). It monitors the health of each
resource through callbacks to the resources. Time Service maintains consistent time
within the cluster.
The Cluster Services in each node of a cluster are in constant communication with
each other. In small clusters, all nodes are in direct communication. Intra-cluster
communication uses RPC mechanisms to guarantee reliable and one-time delivery of
messages. Applications are linked to the clustering services through Microsoft Cluster
Server Resource DLL (dynamic link library). These resources may be customized to
provide advanced services such as automated installation, to speed shutdown and
recovery, or to detect subtle error conditions
