Cluster Components and Requirements
Your cluster requires the following components:
• Operating System
• Cluster nodes(servers)
• Cluster Storage
Operating System
Table 1-1 provides an overview of the supported operating systems. See your
operating system documentation for a complete list of features.
NOTE: Some of the core services are common to all the operating systems.
NOTE: The amount of RAM supported per node also depends on your cluster platform.
NOTE: Running different operating systems in a cluster is supported only during a
rolling upgrade. You cannot upgrade to Windows Server 2003, Enterprise x64
Edition/Windows Server 2003 R2, Enterprise x64 Edition. Only a new installation is
permitted for Windows Server 2003, Enterprise x64 Edition/Windows Server 2003 R2,
Enterprise x64 Edition.
NOTE: MSCS and Network Load Balancing (NLB) features cannot coexist on the
same node, but can be used together in a multi-tiered cluster. For more information,
see the Dell High Availability Clusters website at www.dell.com/ha or the Microsoft
website at www.microsoft.com.
