Prevent Loss of Services in a WAN Failure
Prevent Loss of Services in a WAN
Failure
The SBM provides survivable communication services in the event of a WAN
failure. If you find that, when the WAN link fails, the SBM provides services
for about fifteen minutes and then stops providing services, your site might
not be properly configured for the SBM deployment. The branch site requires
local DNS services. Your company’s solution designers should read the HP
SBM Planning and Design Guide and plan how they will provide these
services.
