A.2.1 Servers/Network

What has to be considered when operating multiple search servers that are different in hardware specification?

If the machines with different specification, such as the number of CPU block on a search server or the size of memory etc., are used in search process, the system waits for the search result from the search server whose performance is the lowest (slowest) and then returns the result to an application.
As a result, the performance of the whole system depends on the lowest performance search server. Therefore, the servers with same specification are recommended.

Refer to the Operator's Guide for more information.

Is there any influence on the Shunsaku operation if director servers and search servers are constructed on the LAN with different segment?

It is necessary to set the LAN environment (such as routing) so that the TCP/IP network is available between both segments. However, the director servers and search servers in Shunsaku operation can be constructed on the LAN of different segments.

For the best performance of Shunsaku, the private line should be used between director servers and search servers. If the data that is not related with the Shunsaku process flows between director servers and search servers, there might be an influence on performance from the network load.
