* High-availability Service Management - Provides failover of services from one cluster node to another in case a node becomes inoperative.
* Cluster administration tools - Configuration and management tools for setting up, configuring, and managing a Red Hat cluster. The tools are for use with the Cluster Infrastructure components, the High-availability and Service Management components, and storage.
* Linux Virtual Server ([[LVS]]) - Routing software that provides IP-Load-balancing. LVS runs in a pair of redundant servers that distributes client requests evenly to real  servers that are behind the LVS servers.
Optional components that are outside the scope of [[RHCS]] are:
* GFS2 - Global File System v2 provides a cluster file system for use with Red Hat Cluster Suite. GFS/GFS2 allows multiple nodes to share storage at a block level as if the storage were connected locally to each cluster node.
* Cluster Logical Volume Manager ([[CLVM]]) - Provides volume management of cluster storage.
* Global Network Block Device ([[GNBD]]) - An ancillary component of GFS/GFS2 that exports block-level storage to Ethernet. This is an economical way to make block-level storage available to GFS2.

Note: This is a dumping ground for me to use while reading more into detail on RHCS v2 clustering.

Overview

These notes came from this Red Hat PDF (single, multiple HTML pages).

Types

Four major types of clusters:

  • Storage (GFS/GFS2)
  • High availability (aka "Failover Cluster", High Availability Systems Management)
  • Load balancing (Linux Virtual Server)
  • High performance (aka "Computational Cluster" or "Grid Computing")

Implemented clusters can combine the above types.

RHCS Components

  • Cluster infrastructure - Provides fundamental functions for nodes to work together as a cluster: configuration-file management, membership management, lock management, and fencing.
  • High-availability Service Management - Provides failover of services from one cluster node to another in case a node becomes inoperative.
  • Cluster administration tools - Configuration and management tools for setting up, configuring, and managing a Red Hat cluster. The tools are for use with the Cluster Infrastructure components, the High-availability and Service Management components, and storage.
  • Linux Virtual Server (LVS) - Routing software that provides IP-Load-balancing. LVS runs in a pair of redundant servers that distributes client requests evenly to real servers that are behind the LVS servers.

Optional components that are outside the scope of RHCS are:

  • GFS2 - Global File System v2 provides a cluster file system for use with Red Hat Cluster Suite. GFS/GFS2 allows multiple nodes to share storage at a block level as if the storage were connected locally to each cluster node.
  • Cluster Logical Volume Manager (CLVM) - Provides volume management of cluster storage.
  • Global Network Block Device (GNBD) - An ancillary component of GFS/GFS2 that exports block-level storage to Ethernet. This is an economical way to make block-level storage available to GFS2.

Acronyms

  • CCS: Cluster Configuration System
  • CLVM: Clustered Logical Volume Manager
  • CMAN: Cluster MANager
  • DLM: Distributed Lock Manager
  • GFS2: Global File System (version 2)
  • GNDB: Global Network Block Device
