Ip Address Requirements For Flat (Unified) Networks - HP StoreAll Series Installation Manual

IMPORTANT:
HP StoreAll 9730 Storage systems default to a flat network configuration that places the chassis
management components on one subnet and the user/cluster components on a separate
subnet. Nodes are configured to access the user, cluster, and management networks through
a single bond attached to the user/cluster subnet. Node access to the components on the
management subnet requires a route in the customer network that connects the management
and user/cluster subnets.
The default flat network layout requires the configuration of a router to provide a level-3 route
that connects the user/cluster subnet and the management subnet. The setup process does 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 ping the OA to verify the route between the
user/cluster and management subnets. If the verification is unsuccessful, the installer software
prompts the user to correct the problem before proceeding.

IP address requirements for flat (unified) networks

Obtain the following IP addresses when performing the installation for the flat (unified) network.
The HP StoreAll Storage 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.
Subnet Minimum number of addresses
user/cluster 1 (one virtual IP address to assign to the entire
cluster for management use)
user/cluster 2 ( virtual IP address for failover)
user/cluster 2 (one IP address per server to assign to the
network bond)
