HP StoreAll Storage Network Best Practices Guide

IP address usage
In this configuration, the StoreAll 9730 requires the following IP addresses.

Because of the manner in which the OA dynamically assigns the addresses to the enclosure
components, all enclosure bays must have addresses assigned for potential management components
even if the bay will not be populated in the shipped configuration. The enclosure management IP
addresses are assigned when the enclosure is initially configured.
Customer use of VLANs or multiple user network VIFs can require additional IP addresses beyond
those specified in this table.
Management subnet
When using the flat configuration, HP recommends that the management network be placed on a
separate subnet to limit the amount of non-management traffic that the enclosure components need
to process. The management interfaces are implemented by embedded systems that do not have
the processing power of a full server and can potentially be overwhelmed if subjected to the full
network traffic of the data/cluster subnet.
It is the customer’s responsibility to ensure that a route exists between the user/cluster subnet and
the management subnet. Since the route must be set up somewhere in the customer’s networking
infrastructure, it is not possible for the StoreAll platform to automatically create this route as part
of the installation process.
Physical description
The physical connection from the enclosure to the customer network is routed through either the
VC modules or the OA modules. Network traffic between the enclosure and the customer network
must traverse these modules to exit the enclosure. All other physical connections are routed internally
via the enclosure’s midplane. Network traffic between servers within an enclosure is routed through
the VC modules and does not count against the total external bandwidth availability.
