Avaya 555-245-600 manual S8720 and S8730 Servers, S8700-series Servers

Avaya Application Solutions platforms

Because the inter port network TDM traffic flow is supported by a Center Stage Switch (CSS) or an Asynchronous Transfer Mode (ATM) switch using fiber-optic cables, this configuration is called fiber-PNC. The call control traffic between the server and the gateways is usually, but not necessarily, over a private dedicated Ethernet network that is provided by Avaya.

This solution is scalable to up to 44 port networks (PNs) through CSS configuration, and up to

64 PNs in an ATM configuration. The fiber-PNC solution has three reliability options:

●Standard. Duplicated S8700-series Servers with memory shadowing, two uninterruptible power supplies (UPS), one Layer-2 Ethernet switch, and one IPSI in each IPSI-connected PN.

●High. Standard reliability, plus a second Layer-2 Ethernet switch and a second IPSI in each IPSI-connected PN. This design provides for a second redundant call control network.

●Critical. High reliability plus duplication of the bearer network.

S8720 and S8730 Servers

The Avaya S8720 and S8730 Server Platforms are high-performance servers with AMD Opteron processors running Avaya Communication Manager software. The S8720 is a replacement server for the S8700 and S8710 Servers and the S8730 is a replacement for the S8720 Server. The S8720 and S8730 support a software duplication option that eliminates the need for the DAJ1 and DAL1 or DAL2 hardware-assist duplication cards.

The S8720 and S8730 systems support the Avaya MCC1, SCC1, CMC1, and G650 Media Gateways. The Avaya G700, G450, G350, G250, and G150 Media Gateways are also supported if there is a TCP/IP connection between the media gateway and a C-LAN circuit pack located in a MCC1, SCC1, CMC1, or G650 Media Gateway. The S8720 and S8730 have the capacity to support up to 64 port networks.

The S8720 Server is available in two configurations:

●Standard configuration.

●Extra large configuration that provides higher capacities.

The S8730 Server is available in a single extra large configuration with 4 GB of RAM and RAID controllers and an optional duplicated hard disk.

S8700-series Servers

Table 4: Avaya Application Solutions comparison matrix — components, performance, and capacities on page 34 summarizes the performance and capacity specifications of the Avaya S8700-series Servers.

The Avaya S8700-series Server platform always consists of two servers running on a Linux operating system. In S8700-series fiber-PNC and IP-PNC configurations, the S8700-series Server provides the main feature and management processing capabilities of the system. The server is connected to other system and external components primarily through IP networks.
