Local failover option
Server for Avaya SIP Enablement Services
An optional local failover option may be configured to replicate the SES database and server
software for any particular system node (home, edge, or combination home/edge). In this
duplicated (duplex) configuration, one server is active and the other is in standby mode. If the
active server fails or is taken out of service, it "fails-over" to the duplicated server. The
duplicated server then becomes active and maintains service. When the originally active server
is put back into service, it goes into standby mode. The duplicated server continues in active
mode, providing service to the SIP endpoints.
In each server in a duplex server configuration, a dual-port NIC card must be installed. One port
of the dual-port NIC card on each server is then connected to that of the other server with a
CAT5e or Cat 6 cable. The servers use this link to maintain database synchronization.
Additionally, an RS-232 serial port on each of the servers must be cabled together. Each server
uses this link for monitoring the status of the other server.
Components
The server hardware required for an Avaya SES Server Release 3.1 is the IBM e-server xSeries
305 (S8500A), an IBM xSeries 306 (S8500B), or an IBM xSeries 306m (S8500C). These
servers are referred to as the x305 or x306.
Note:
Note: SES runs on simplex x305 (S8500A) platforms only, not on duplex x305
platforms.
IBM includes various CDs with its e-servers, including Director CDs, NetXtreme gE CD, eServer
xSeries 305 CD, and Enhanced Diagnostics CD.
! CAUTION:
CAUTION: The IBM CDs are not used for installation of SES. You must use the Avaya SES
Setup and Install CD.
An IBM Installation Guide is provided with the server. This guide includes instructions for
installing the IBM Remote Supervisor Adapter (RSA) module and for installing the dual inline
memory module (DIMM). Note that this memory must be added before use.
The IBM Installation Guide for the x306 includes instructions to install the SAMP card, and
instructions on how to install extra memory.
To be used as an SES Home Server with fewer than 3,000 users, the x305 or x306 needs one
additional 512MB DIMM of PC2100 266MHz CL2.5 ECC DDR SDRAM added to the existing
512MB installed by default. The total installed RAM is then 1GB.
To be used as an SES Edge Server, or as a Home supporting more than 3,000 but less than
6,000 users, the x305 or x306 needs two 1GB DIMMs in addition to the RAM above. The total
installed RAM is then 3GB.
