We are in the middle of standing up new clustered exchange servers into our new data center. Part of the process is to build the new cluster servers and move mailboxes over to new exchange server. We probably will build a new cluster within a year and go for exchange 2007. Knowing the cluster components are critical therefore I have decided to post below table here at my blog. Microsoft Cluster Service is consisting of several device drivers and services. These modules reside on top of the Operating system (Windows enterprise edition) and behave as a service. The cluster service provides basic functions that the operating system needs in order to support clustering
- Understanding each component is crucial going trough setting up and managing clusters.
- It makes daily admin life easier in my opinion.
Maintains resource group ownership of cluster nodes
based on resource group node preferences and the
Availability of cluster nodes.
Utilizes the cluster resource API and RPCs to maintain
communication with the resource DLLs. Each monitor runs
as a separate process.
Works in conjunction with the resource monitors to
manage resource functions within the cluster such as
failovers and restarts.
Maintains and updates application states and registry
keys on the cluster quorum resource.
Configuration Database Manager
Maintains and ensures coherency of the cluster database
on each cluster node that includes important cluster
information such as node membership, resources,
resource groups, and resource types.
Processes events relating to state changes and requests
from cluster resources and applications.
Manages cluster node membership and polls cluster
nodes to determine state.
Event Log Replication Manager
Replicate system event log entries across all cluster
Global Update Manager
Provides updates to the Configuration Database
Manager to ensure cluster configuration integrity and
Provides management of all cluster service objects and
the interface for cluster administration.
Works with the Checkpoint Manager to ensure that the
recovery log on the cluster quorum disk is current and
