Manager by a firewall. The firewall's rules allow a storage subsystem to be accessed only by the
Device Manager server or by any other required management application. Management clients
accessing Device Manager are not allowed to pass traffic through the firewall to directly talk to a
managed storage subsystem, but can directly participate in management operations via Device
Manager or a management application.
This configuration is the second most secure, and is more flexible than the most secure option.
While this configuration protects the devices under management, it does not protect the
management application servers themselves. Therefore, all management application servers should
be hardened to the maximum possible extent.
CAUTION: When Physical View of XP24000/XP20000 or XP12000/XP10000/SVS200, or XP
Remote Web Console of XP1024/XP128 is launched, Java Web Start and the web browser on the
web client computer directly communicate with the storage subsystem. For this reason, if the web
client computer and the storage subsystem exist on different networks, you must set up the
networks so that the computer and the storage subsystem can directly communicate with each
other.
The following figure illustrates a separate management LAN plus firewalled devices under
management.

management servers plus separate management LAN
In this configuration, the management servers themselves act as the intersection point between the
management LAN and production LAN. The server running the Device Manager or other
management applications is dual-homed. One NIC is attached to the management LAN along with
the managed devices. The second NIC is attached to a production LAN along with the management
clients (for example, the Device Manager GUI). Because the management application servers
