AS/400 IBM Network Station: Techniques for Deployment in a WAN
Figure 11. Flash Card Support for Emulators from a Remote Location
3.2.2 Scenario Advantages
The scenario has the following advantages:
• Users at the remote location experience quick boot up times as the
required code to start the IBM Network Station is contained on the local
Flash card or file system.
• The emulation applications is also located on the Flash card and does not
need to be sent across the network.
• The WAN traffic is reduced releasing the bandwidth for other use.
• The volatile user configuration settings continues to be managed on the
central server system.
• User authentication is maintained and authenticated on the central server
system.
• The use of peer boot is allowed in the future.
3.2.3 Scenario Disadvantages
The following disadvantages apply to this scenario:
• There is no automated central management of the Flash cards.
The system administrator must ensure that the remote user’s Flash card
remains up to date when any new releases are applied to the central
server system.
• The Flash card is a single point of failure for the remote user.
