Junos Space Appliance Overview
The Juniper Networks Junos Space Appliance is a dedicated hardware device that is
engineered to provide the computing power and meet specific requirements to be able
to install and run the Junos Space Network Management Platform. Junos Space Network
Management Platform is an open, extensible platform that simplifies the management
and orchestration of networks, and allows you to develop and host applications that
simplify network operations, scale services, and automate support. The all-in-one design
of the Junos Space Appliance enables administrators to easily deploy Junos Space
Network Management Platform.
Junos Space Appliances are currently available in two models: JA1500 and JA2500.
The JA1500 Junos Space Appliance has been tested with up to six appliances connected
in a cluster (fabric) ability to manage up to 15,000 devices without the Network Monitoring
functionality enabled.
The JA2500 Junos Space Appliance has been tested with up to eight appliances (four
Junos Space nodes and two database (DB) nodes and two fault monitoring and
performance monitoring (FMPM) nodes, or six Junos Space nodes and two FMPM nodes)
connected in a cluster (fabric) with the ability to manage up to 25,000 devices.
