Microsoft cluster service components

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.
  

Component	Role/Function
Node Manager	Maintains resource group ownership of cluster nodes based on resource group node preferences and the Availability of cluster nodes.
Resource Monitor	Utilizes the cluster resource API and RPCs to maintain communication with the resource DLLs. Each monitor runs as a separate process.
Failover Manager	Works in conjunction with the resource monitors to manage resource functions within the cluster such as failovers and restarts.
Checkpoint Manager	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.
Event Processor	Processes events relating to state changes and requests from cluster resources and applications.
Membership Manager	Manages cluster node membership and polls cluster nodes to determine state.
Event Log Replication Manager	Replicate system event log entries across all cluster nodes.
Global Update Manager	Provides updates to the Configuration Database Manager to ensure cluster configuration integrity and consistency.
Object Manager	Provides management of all cluster service objects and the interface for cluster administration.
Log Manager	Works with the Checkpoint Manager to ensure that the recovery log on the cluster quorum disk is current and consistent.
