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.
