Junos Space JA1500 Appliance Overview
The Junos Space JA1500 appliance is a Juniper Networks, dedicated, physical, hardware
device that is engineered to provide the computing power and specific requirements
needed to install and run the Junos Space application. The JA1500 appliance all-in-one
design makes the Junos Space application deployment simpler by giving administrators
a turnkey solution. You can power up a the JA1500 appliance, make required configuration
changes, then start using the Junos Space application without concerning yourself with
hardware and OS and application installation. (See Figure 1 on page 3).
Figure 1: Junos Space JA1500 Appliance
The JA1500 appliance allows administrators to migrate from a strategy of one large
server in the corner, to distribute multiple servers based on load and geography. You can
combine Junos Space appliances in clusters for high availability or increased throughput.
The JA1500 appliance ensures that consistent infrastructure is deployed across an
organization, reducing complexity. The JA1500 appliance means that only one
vendor—Juniper Networks—supports integrated components reducing complexity.
The administrator can also deploy and run the Junos Space application as a virtual
appliance. The administrator can combine Junos Space appliances in clusters for high

Understanding How Nodes Are Connected in a Fabric
Each Junos Space appliance (physical or virtual) that you install and configure is
represented as a single node in the fabric. You can add nodes without disrupting the
services that are running on the fabric. When you install and configure the first appliance,
Junos Space automatically creates a fabric with one node. For each additional appliance
you install and configure, you must add a node to logically represent the appliance in the
fabric. Youadd nodes to the fabric from the Administration workspace in the Junos Space
user interface. Each node that you add to the fabric increases the resource pool for the
node functions to meet the scalability and availability requirements of your network. By
default, Junos Space automatically enables node functionality across the nodes in the
fabric to distribute workload.The nodes in the fabric work together to provide a virtualized
resource pool for each of the node functions: load balancer, database, and application
logic.
In a fabric comprising two or more nodes, Junos Space provides failover when a node
functioning as the active server (load balancer server or database server) goes down. By
default, Junos Space marks a particular node down and routes failover requests to the
node that Junos Space designates as standby server. Junos Space uses a heartbeat
mechanism to check whether the nodes in the fabric are running. When a node functioning
as the active server fails (the appliance crashes or stops sending heartbeats), the node
functioning as the standby server takes over all resources that were managed by the
node functioning as active server. Nodes in a Junos Space fabric rely on IP multicast
messagesto discover each other, thereforeensure that IP multicast packets are reachable
among all nodes in the Junos Space fabric.

Documentation
To add, manage, and monitor the nodes in the fabric, a Junos Space user connects to a
single Web IP address. The IP address of first (active) node and second (standby) node,
and the Web (virtual) IP address must all be in the same subnet. The Web IP address
must work on both the first and second node in the fabric. When both nodes are in same
subnet, and the first (active) node goes down, the second (standby) node becomes the
active node and packets continue to be directed from the router to the Junos Space Web
IP address, and then to the second node. However, if the second (standby) node is
configuredin a different subnet from the first (active) node, and the first node goes down,
the second node becomes the active node, but because the Web IP address now points
to a different subnet address, packets originally destined for first node will not be received
by the second node.

NTP Time Source For Each JA1500 Appliance
To ensure consistent behavior among all nodes in a multinode fabric, each node’s time
must be synchronized with every other node in the fabric. When you configure each Junos
Space JA1500 appliance with an NTP server, you ensure that, if the first node (which is
used to synchronize time for all nodes in the fabric) goes down, all other nodes in the
fabric remain synchronized. To ensure this behavior, all nodes in a fabric must use the
same external NTP source that you configure for the first appliance.
NOTE: By default, Junos Space translates time so that the time displayed in
the user interface corresponds to Junos Space server time, but is mapped to
the local time zone of your client computer.
The default system clock for a JA1500 appliance may not be precise enough for some
networks. To ensure time synchronization across all nodes in the fabric, Juniper strongly
recommends that you use the following guidelines:
Chapter 1: Overview of the Junos Space JA1500 Appliance
•
Add an NTP server to the first virtual appliance during initial setup.
•
For each additional appliance, add the same NTP server that you specified for the first
appliance.

Fabric Management Overview
You can deploy Junos Space appliances to create a fabric that provides the scalability
and availability that your managed network requires as you add more devices, services,
and users.
A Junos Space fabric comprises one or more IP-connected nodes. A node is a logical
object that represents a single Junos Space JA1500 appliance or Junos Space virtual
appliance, its operating system, and the Junos Space software that runs on the operating
system. Each Junos Space appliance or virtual appliance that you install and configure
is represented as a single node in the fabric. You can add nodes without disrupting the
services that are running on the fabric. When you add nodes to the fabric, you can manage
and monitor the nodes from the Administrationworkspace. To add, manage, and monitor
NOTE: You must add the NTP server before you add the first node to the
fabric from the user interface.

nodes in the fabric, a fabric administrator connects to a single virtual IP address. See

Fabric Nodes
Single Node Functionality
When the fabric comprises a single appliance, all devices in the managed network connect
to the appliance. When you install and configure the first appliance, Junos Space
automatically creates a fabric with one node. By default, a fabric that consists of a single
node provides complete Junos Space management functionality. The following node
functions are enabled for the node:
•
Load Balancer— for processing HTTP requests from remote browsers and NBI clients
•
Database— for processing database requests (create, read, update, and delete
operations)
•
Application Logic— for processing Junos Space service requests and Data Manipulation
Language (DML) workload (device connectivity, device events, and logging)
NOTE: A fabric that comprises a single node provides no workload balancing
and no backup if the appliance goes down.
Copyright © 2012, Juniper Networks, Inc.10
Multinode Functionality
As your network expands with new devices, services, and users, you can add Junos Space
appliances to handle the increased workload. When you install and configure the first
appliance, Junos Space automatically creates a fabric with one node. For each additional
appliance you install and configure, you must add a node to logically represent the
appliance in the fabric. Each node that you add to the fabric increases the resource pool
for the node functions to meet the scalability and availability requirements of your network.
By default, Junos Space automatically enables node functionality across the nodes in
the fabric to distribute workload. The nodes in the fabric work together to provide a
virtualized resource pool for each of the node functions: load balancer, database, and
application logic.
The Junos Space node functions distribute workload across operating nodes according
to the following load-distribution rules:
•
Chapter 1: Overview of the Junos Space JA1500 Appliance
LoadBalancer—When a node that functions as the active load balancer server is down,
all HTTP requests are automatically routed to the standby load balancer server that
is running on a separate node.
•
Database— When a node that functions as the active database server is down, all
database requests (create, read, update, and delete) are routed to the node that
functions as the standby database server.
•
Application Logic— Device connections and user requests are distributed among the
nodes, and device-related operations are routed to the node to which the device is
connected.
Junos Space uses the following algorithm to ensure that the number of devices
connected to a node does not exceed the threshold limit for each node:
Threshold Limit = [ (number of devices in database) / (number of nodes running) ] + 2
The following workflow describes how the node functions are enabled across the fabric
as nodes are added:
•
First node: The load balancer, database, and application logic functions are enabled
on the node. Each node function provides both scalability and high availability. Figure
6 on page 11 shows all functions enabled on a fabric comprising one node.
Figure 6: Functions Enabled on Fabric Containing One Node
11Copyright © 2012, Juniper Networks, Inc.
JA1500 Appliance User Guide
•
Second node: When a second node is added to the fabric, the first node functions as
the active load balancer server and active database server, and the second node
functions as the standby load balancer server and standby database server. The load
balancer and application logic node functions provide scalability and high availability.
The database node function on the second node provides high availability only. Figure
7 on page 12 shows the functions enabled on a fabric comprising two nodes.
Figure 7: Functions Enabled on Fabric Containing Two Nodes
•
Third and subsequent nodes: Only the application logic functionality is enabled on the
third node to provide equal distribution of device connections and user requests across
all nodes, and to route device-related operations to the node to which the device is
connected. The application logic functionality provides both scalability and high
availability. Figure 8 on page 12 shows the functions enabled on a fabric comprising
three nodes.
Figure 8: Functions Enabled on Fabric Containing Three Nodes
NOTE: For the third node and each subsequent node added to the fabric,
only the application logic functionality is enabled.

Node Function Availability
In a fabric comprising two or more nodes, Junos Space provides failover when a node
functioning as the active server (load balancer server or database server) goes down. By
default, Junos Space marks a particular node down and routes failover requests to the
node that Junos Space designates as standby server. Junos Space uses a heartbeat
mechanism to check whether the nodes in the fabric are running. When a node functioning
as the active server fails (the appliance physically crashes or stops sending heartbeats),
the node functioning as the standby server takes over all resources that were managed
by the node functioning as the active server.
