NOTE: You can extend system performance and data capacity by expanding
the minimum requirements specified for each component. See “Hardware
Recommendations” on page 201 for more information about the hardware
and software appropriate for your specific network.
System Requirements—User Interface
Table 8 on page 7 describes the minimum system requirements that must be met for
the User Interface.
Table 8: Minimum System Requirements—User Interface
Minimum Requirement Component
Microsoft Windows Vista, or
Microsoft Windows XP, or
RHEL 32-bit ES 4.0 or 32-bit ES 5.0, RHEL 32-bit AS 4.0 or RHEL 32-bit AS
5.0 (Minimal and Full Install) US English versions only
Software
IBM compatible PC
Pentium 4 or equivalent
RAM: 2 GB. For managing large scale setups (for example, with more than
1000 devices on the NSM server), Juniper recommends a minimum of 4
GB RAM.
384 Kbps (DSL) or LAN connection — minimum bandwidth required to
connect to the NSM management system.
Hardware
Choosing Standalone, Distributed, or High Availability Configurations
The two most important installation considerations are:
• Scale — The size of the network.
The NSM management system is designed to scale from the management of a few
devices to huge networks of up to 3000 devices. For smaller networks, you can install
the entire system on a single Linux or Solaris server. For larger networks, you can
distribute the NSM management system by installing the Device Server and GUI Server
on separate machines, and by using external shared disk systems.
•
Failure tolerance — The effect on the organization upon failure of an NSM component
and the downtime during repair.
You can increase fault tolerance by installing a standby management system on a
single server for smaller installations, or on distributed servers for larger installations.
