Overview of Virtual System
A virtual system is a logical device created on a physical
device. Virtual systems are independent from each other.
A FW can be logically
divided into multiple virtual systems. Like a physical device, each
virtual system has its interfaces, address sets, users and user groups,
routes, and policies. Virtual system administrators can manage and
configure them.
Virtual systems have the following features:
- Each virtual system has its own administrators and can be managed
independently. With virtual systems, a large network can be divided
into smaller subnets with each being served by a virtual system, simplifying
the network management.
- Each virtual system has its own configurations and routing table
so that networks connected to different virtual systems can have overlapping
private addresses.
- Each virtual system has its own resource quota so that a busy
virtual system has no impact on other virtual systems.
- The traffic of different virtual systems is separated to ensure
security. However, different virtual systems can still communicate
with each other if needed.
- Virtual system technology reduces hardware investment, power consumption,
and equipment footprint.
