CHAPTER 6 Redundant Configuration

 

6.5

Redundancy of the Business LAN (Use of 

PRIMECLUSTER GLS)

If MMBs and GSWBs are duplicated, networks in a PRIMEQUEST cabinet, such as 
the management LAN, the private LAN, and the business LAN are also duplicated.  
This section describes the implementation of redundancy for a business LAN as 
related to the construction of a business system.

To implement redundancy for of a network and the network interface, at least two 
network interfaces and optional software to switch the interfaces are needed.

Linux supports PRIMECLUSTER Global Link Services (GLS) as optional software.  
Windows supports duplication using a driver.  This section shows an example of 
network redundancy that can be implemented by combining PRIMEQUEST and 
PRIMECLUSTER GLS.  For details, see the manual for PRIMECLUSTER GLS.
