Overview

novdocx (ENU) 29 January 2007

Overview

Novell®Cluster ServicesTM is a server clustering system that ensures high availability and

manageability of critical network resources including data, applications, and services. It is a

multinode clustering product for Linux that is enabled for Novell eDirectoryTM and supports failover,

failback, and migration (load balancing) of individually managed cluster resources.

1.1 Product Features

Novell Cluster Services includes several important features to help you ensure and manage the

availability of your network resources. These include:

Support for shared SCSI, iSCSI or fibre channel storage area networks.

Multinode all-active cluster (up to 32 nodes). Any server in the cluster can restart resources

(applications, services, IP addresses, and file systems) from a failed server in the cluster.

A single point of administration through the browser-based Novell iManager cluster

configuration and monitoring GUI. iManager also lets you remotely manage your cluster.

The ability to tailor a cluster to the specific applications and hardware infrastructure that fit

your organization.

Dynamic assignment and reassignment of server storage on an as-needed basis.

The ability to automatically notify administrators through e-mail of cluster events and cluster

state changes.

1.2 Product Benefits

Novell Cluster Services allows you to configure up to 32 Linux servers into a high-availability

cluster, where resources can be dynamically switched or moved to any server in the cluster.

Resources can be configured to automatically switch or be moved in the event of a server failure, or

they can be moved manually to troubleshoot hardware or balance the workload.

Novell Cluster Services provides high availability from commodity components. Lower costs are

obtained through the consolidation of applications and operations onto a cluster. The ability to

manage a cluster from a single point of control and to adjust resources to meet changing workload

requirements (thus, manually “load balance” the cluster) are also important benefits of Novell

Cluster Services.

An equally important benefit of implementing Novell Cluster Services is that you can reduce

unplanned service outages as well as planned outages for software and hardware maintenance and

upgrades.

Reasons you would want to implement Novell Cluster Services include the following:

Increased availability

Improved performance

Low cost of operation

Scalability

Disaster recovery

Data protection

Server Consolidation

Storage Consolidation

Shared disk fault tolerance can be obtained by implementing RAID on the shared disk subsystem.

An example of the benefits Novell Cluster Services provides can be better understood through the

following scenario.

Suppose you have configured a three-server cluster, with a Web server installed on each of the three

servers in the cluster. Each of the servers in the cluster hosts two Web sites. All the data, graphics,

and Web page content for each Web site is stored on a shared disk subsystem connected to each of

the servers in the cluster. The following figure depicts how this setup might look.

Figure 1-1 Three-Server Cluster

During normal cluster operation, each server is in constant communication with the other servers in

the cluster and performs periodic polling of all registered resources to detect failure.

Suppose Web Server 1 experiences hardware or software problems and the users depending on Web

Server 1 for Internet access, e-mail, and information lose their connections. The following figure

shows how resources are moved when Web Server 1 fails.
