IMPORTANT:
In previous releases, the X9720 system shipped with access to the management,
user and cluster networks through a single FSN bond. The field setup moved the user and cluster
network access to a separate bond once the connection between a FSN and the customer network
was established.
X9730 systems default to a unified network configuration that places the chassis management
components on one subnet and the user/cluster components on a separate subnet. File serving
nodes are configured to access the user, cluster, and management networks through a single bond
attached to the user/cluster subnet. File serving node access to the components on the management
subnet requires a route in the customer network that connects the management and user/cluster
subnets.
IMPORTANT:
The default unified network layout requires the customer to configure a router to
provide a level-3 route that connects the user/cluster subnet and the management subnet. The setup
process will not complete if the level-3 route is not in place for system installation. During the setup
process, the installer software makes sure that it can ICMP ping the OA to verify the route between
the user/cluster and management subnets. If it is unsuccessful, the installer software prompts the
user to correct the problem before proceeding.
IP address requirements
You will need the following IP addresses when you perform the installation for the unified network.
The HP IBRIX X9000 Network Storage System Network Best Practices Guide describes the
components in more detail, and also lists IP address requirements for the other supported network
layouts.

You also need to provide the IP addresses of the DNS servers, NTP servers, and, optionally, the
default gateway.
HP recommends that you use sequential addresses for the blades, iLOs, and Interconnect.
