2.2.2 Designing the Server Configuration

Design the configuration of the servers where conductors, directors, sorters, and searchers will be allocated. Shunsaku can be operated using the following server configurations:

• Single server operations
• Operations with separate searcher servers
• Operations with applications on separate servers
• Operations with additional director servers
• Operations with additional sort servers

The following section explains how to determine the number of director servers, search servers and sort servers.

Determining the Number of Director Servers

If placing more than one director on a single director server is likely to reach the limits of the hardware capacity, prepare more than one director server and install a director on each server.

Determining the Number of Search Servers

If the amount of data stored in Shunsaku is likely to exceed the memory capacity for the search server, prepare more than one search server according to the amount of data stored.

To obtain the full performance of searchers, install search servers so that a single CPU is allocated to each searcher.

Determining the Number of Sort Servers

If the number of concurrent sort processes is large and sort processes consume a large amount of CPU capacity, locate multiple sort servers to distribute the load.

Director servers, search servers and sort servers can be added while the system is in operation.
