Server Environment Hardware Requirements

Table 3 lists the minimum hardware requirements for the server environment.

Disk Space Requirements

Siebel Enterprise Server architecture is designed to scale across multiple application servers to meet the needs of large, complex deployments. For further assistance in capacity planning and sizing hardware platforms for Siebel Enterprise Server, contact your Oracle sales representative for Oracle Advanced Customer Services to request assistance from Oracle's Application Expert Services.

The number of servers, the CPU resources, and the memory resources required for operating Siebel Business Applications increases with the number and types of users and Siebel modules deployed.

Up to 1 gigabyte of disk space can be required on each application server to install the Siebel Enterprise Server software. In addition, servers operating Siebel Remote require 15 MB of usable disk space for each mobile user. Oracle recommends using high-performance and high-availability storage solutions as appropriate for use in deployments of Siebel applications. This is especially important in high- capacity deployments. Oracle recommends using high-performance disks or fault-tolerant disk arrays for all application servers, file system servers, and database servers.

Hardware or software high-availability disk configurations are critical for Siebel Remote Servers, Database Servers, and Siebel File System Servers. It is recommended that other Siebel Application Servers, Siebel Web Servers and other Siebel Server components are configured to use hardware or software RAID level 1, SAN or comparable configurations.

About Clustering

High-availability solutions, such as clustering, are also recommended on critical components and may be used in conjunction with the high-availability storage solutions stated in Disk Space Requirements. Clustering is critical for high availability of the Gateway Name Server, Remote Servers and the Database Server. Clustering is also recommended for any application server that is not load-balanced.

You are responsible for ensuring that clustering is supported on each server component. Oracle users are responsible for making sure that Siebel Server hardware operates with the supported server operating systems and clustering solutions. See Table 5 for a list of the supported server operating systems. See Table 7 for a list of the supported Web servers. For more information about clustering, see Cluster Technology Support.
