Shared; Private; Service Processor Connectivity; Service Processor Connectivity Options - HP 3PAR StoreServ 7450c Planning Manual

Shared

With a shared network topology, the storage system and SP share the internal customer network.
A shared topology requires all of the following:
A static IP address and system name for the storage system
A minimum two Ethernet connections from a switch or hub to the storage system controller
nodes, if there are more than two nodes
A static IP address for the SP
One Ethernet connection from a switch or hub to the SP

Private

With a private network topology, both the storage system and SP reside on the same private
network segment of the customer local area network. All management workstations used to
administer the system must also reside on the same private network segment. A private topology
requires all of the following:
A static IP address for the storage system
Two Ethernet connections from the storage system to a private network segment
A minimum two Ethernet connection from the SP to the private network segment, if there are
more than two nodes
A static IP address for the SP
At least one management station on the private network segment

Service Processor Connectivity

The SP is used to provide remote error detection and reporting, and to support diagnostic and
maintenance activities involving the storage system.
HP uses the data collected by the SP to maintain, troubleshoot, and upgrade any HP 3PAR storage
equipment on the customer site. To perform these activities, the SP must communicate with HP
Central or a local service provider. The connection between the SP and HP Central or a local
service provider can be made by using the customer network and the Internet. Connections using
the customer network pass through a customer's firewall. When a designated management
workstation resides on the same network as the SP and is configured to access the SP, a customer
has the option to block external communications at any time. The SP needs to be on the same
subnet as the storage system.
