Juniper JUNOS SPACE 2.0 - RELEASE NOTES, Руководство по установке

Страница: 19 / 64

The distributed Junos Space Virtual Appliance files are created with 5 GB of disk space,
and you add an additional 40GB of disk resources when you first deploy the virtual
appliance to a VMware ESX server. In many cases, the 45 GB of disk space will be
sufficient; however, if the percent of Junos Space disk resources utilized reaches 80%
capacity, Juniper recommends that you add another 40 GB of disk space to your virtual
appliance. You can monitor the percent of disk space utilized in the Fabric Monitor
inventory panel in the Junos Space user interface.
Configuring an NTP Time Source For Each Appliance
To ensure consistent behavior among all nodes in a multi-node fabric, each node’s time
must be synchronized with every other node in the fabric. When you configure the first
Junos Space Virtual Appliance (and JA1500 Junos Space 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. Additional nodes
installed into the same fabric will automatically get their time setting from the first node
in the fabric without any additional NTP server configuration.
NOTE: By default, Junos Space translates time so that the time displayed in
the user interface corresponds to Junos Space server time, but the time is
mapped to the local time zone of your client computer.
To ensure time remains synchronized across all nodes in the fabric, Juniper strongly
recommends that you add an NTP server to the first appliance (physical or virtual) during
initial set up.
NOTE: You must add the NTP server before you add the appliance/node to
the fabric from the Junos Space user interface.
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 JA1500 Junos Space 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 Administration workspace. To add, manage, and monitor
nodes in the fabric, a fabric administrator connects to a single virtual IP address, as shown
in the illustration.
