CHAPTER 7 High-Availability Configurations with VMware GSX Server

Applications That Can Use Clustering

To take advantage of clustering services, applications need to be clustering-aware.

Such applications can be stateless, such as Web servers and VPN servers. Clustering-

aware applications often include built-in recovery features, like those in database

servers, mail servers, file servers or print servers.

Clustering Software

Available clustering software includes:

• Microsoft Clustering Service (MSCS) — under Windows 2000, MSCS provides fail-

over support for two- to four-node clusters for applications such as databases,

file servers and mail servers. Under Windows Server 2003, MSCS provides failover

support for eight-node clusters.

• Microsoft Network Load Balancing (NLB) — that balances the load of incoming

IP traffic across a cluster of up to 32 nodes for applications such as Web servers

and terminal services.

• Veritas Clustering Service (VCS).

• Novell Clustering Services.

Note: These clustering services are tested and supported by VMware only with

Windows host operating systems.
