BIA config changes when adding an application server to a BI instance(?)

[Former Member]

hi

standard setup is a 1Gb direct production lan (redundant) from the BIA to the host BI 9one server, DBCI). Cu wants to add another app server to the host BI - do they need another lan connectiosn from the app server to the BIA?

I would have thought all BIA request go via the OLAP processor but not sure whether there is one on the app server or not.

Basically; will the setup work with teh existing Lan?

Will adding a connection from the app server to teh BIA improve things?

TIA

Hello Peter,

you can find the answer in the BIA Installation Guide (https://www.sdn.sap.com/irj/sdn/bia)

Productive BIA LAN:

This LAN must be used exclusively for the connection between the BI system and the BI Accelerator. It is mandatory to have the BI Accelerator and the BI system together in a dedicated subnet of their own. Otherwise, full BIA performance cannot be guaranteed.

There has to be a dedicated LAN connection between the BI system as logical unit on the one hand and the BI Accelerator as a logical unit on the other hand. The network reachability between every BI application and every BI Accelerator blade must be guaranteed. This connection should not be established between each BI application server and the BI Accelerator, since a local gateway should be used.
