Chapter 7: ESS Maintenance Object
ESS (Enterprise Survivable Server)
S8700 | 8710 / S8500
The Enterprise Survivable Server (ESS) maintenance object (MO) monitors the status of the
ESS feature.
On the Main server the MO will:
● Monitor the registration status for all administered ESS servers. See display
system-parameters ess for a list of administered ESS servers. The registration status
of all ESS servers is initially checked approximately ten minutes after the Main server
boots up. Subsequent to this, the registration status for all ESS servers is monitored each
time an ESS server registration status change is received at the Main server.
On an ESS server the MO will:
● Monitor the registration status of the active server within an ESS server. Only the active
server of an ESS server pair (
S8700 | 8710), registers with the active Main server. The ESS
MO at an ESS server does not track the registration status of other ESS servers.
● Monitor the IP Server Interface (IPSI) socket connections for all administered IPSI circuit
packs. Each ESS server establishes a socket connection to all administered IPSI circuit
packs. These connections are used to advertise the ESS server administered values to all
IPSIs. If needed, the IPSI will use this socket connection to request service from the
ESS.server
