Cisco Systems Media Gateway Controller Node Manager manual Hardware Requirements, Medium Network

Chapter 1 Installation Overview and Planning

Determine Your Hardware Requirements

•Cisco VSPT (only) installed on a Cisco PGW 2200 Softswitch host machine

•Cisco MNM installed on a network management server and Cisco VSPT installed on a separate server

Caution Cisco MNM is not supported on a Cisco PGW 2200 Softswitch host machine.

Hardware Requirements

The Cisco MNM hardware requirements for various network sizes are described in Table 1-1. Except in a very small network, each operator requires an X terminal workstation.

1.Two-drive machines work for smaller networks that have less traffic and fewer operators. Response time to operator commands slows down as the network grows and additional operators are added.

Note Disk drive requirements are based on the number of drives. The Cisco MNM host machine requires the minimum number of drives indicated in Table 1-1. These are recommendations to aid you in planning. The total amount of disk space required depends on many factors, such as the amount of alarm and performance data collected.

Disk Drives and Database Storage

In a medium or large network, using multiple disk drives to store databases helps alleviate I/O bottlenecks and improves software performance. If you are using multiple disk drives for database storage, or you expect to generate large database files, use raw partitions, as described in the Cisco Element Management Framework Installation and Administration Guide at

http://www.cisco.com/en/US/docs/net_mgmt/element_manager_system/3.2_service_pack_7/installatio n/guide/3_2p7adm.pdf

Note If you are using Unix File System (UFS) partitions, installing more than one drive for database storage does not improve performance because the databases cannot span multiple partitions.
