Siebel Server Environment Hardware Requirements

Table 4 lists the minimum hardware requirements for the Siebel Server environment.

Siebel Enterprise Server architecture is designed to scale across multiple application servers to meet the needs of large, complex deployments. Siebel Global Services can provide further assistance in capacity planning and sizing hardware platforms for Siebel Enterprise Server.

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

Up to 1 GB of disk space can be required on each application server for installation of 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 Oracle deployments. This is especially important in high-capacity deployments. Oracle recommends using high-performance SCSI disks or RAID arrays for all Siebel Servers, file system servers, and database servers.

Hardware or software RAID 5 or comparable 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 configurations.

High-availability solutions—such as clustering—are also recommended on critical components and may be used in conjunction with RAID level 1 or 5 solutions as stated above. Clustering is critical for high availability of the Gateway Server, remote servers and the Siebel Database Server. Clustering is also recommended for any application server that is not load balanced.

Oracle customers are responsible for making sure that clustering is supported on each Siebel Server component. Oracle customers are also responsible for making sure that Siebel Server hardware is supported to operate with the Siebel-supported server operating systems and clustering solutions. See Table 12 for a list of supported server operating systems. See Table 16 for a list of supported Web servers.
