Hardware Recommendations for Hummingbird SearchServer

Hummingbird SearchServer can be installed on the same server as the Siebel Enterprise Server or the Siebel Database Server. For larger installations, however, it is recommended that SearchServer be installed on a dedicated server, with a minimum of 250 MB of RAM. The CPU and memory resources required for operation of Hummingbird SearchServer increase with the number of active users at any one time. Each concurrent user requires approximately 2 MB of RAM on the server. A concurrent user is defined as an employee or partner with search center open, or a customer with the Search view active.

Up to 50 MB of disk space is required on the application server for installation of the Hummingbird SearchServer software. The size of indices is approximately 30% of the size of the original text, and the indexing step requires temporary space of up to two to four times the ultimate size of the index files. Additionally, indices which are based on business components pointing to files in the Siebel file system require additional temporary storage space roughly equal to 2X the size of the compressed files being indexed.
