5. P4000 SAN segment
IMPORTANT:
Instructions and illustrations in this document describe the installation and configuration of a 2–node
P4000 G2 Unified NAS Gateway. If you purchased the 1–node P4000 G2 Unified NAS Gateway,
all instructions related to installing and configuring the second node of the solution do not apply. The
1–node solution does not support full High Availability (HA) capability, but is HA ready and can be
upgraded to a full HA solution by purchasing and installing an additional 1–node P4000 G2 Unified
NAS Gateway.
After installing the P4000 G2 Unified NAS Gateway nodes as detailed in the HP StorageWorks
P4000 G2 Unified NAS Gate wa yQuick Start Guide, the system components should be racked, cabled,
powered on, and you should be logged in to the systems with Administrative privileges. In addition,
P4000 SAN storage should be created and mapped to the P4000 G2 Unified NAS Gateway nodes
using P4000 Centralized Management Console (CMC) software, Microsoft iSCSI Initiator, and
Windows Disk Manager.
For complete information about creating and managing HP StorageWorks P4000 SAN Solutions,
see the user documentation at http://www.hp.com/go/p4000. Click HP Support and Drivers, select
your HP StorageWorks P4000 SAN Solution model, and then click Manuals.
Creating and configuring the cluster
The following section describes the process of creating the P4000 G2 Unified NAS Gateway cluster.
Set IP addresses for the network connections
In order to accurately describe the physical connections between the clustered components, the P4000
G2 Unified NAS Gateways are designated as Server 1 and Server 2 in this section.
Each P4000 G2 Unified NAS Gateway includes six NIC connectors, each reserved for a specific
network connection purpose as shown in the figure below:
• One NIC connector is reserved for heartbeat connectivity between the two P4000 G2 Unified
NAS Gateway storage systems (shown in red).
• Two NIC connectors are reserved for multi-path connectivity to P4000 SAN storage nodes (shown
in green and blue).
• Three NIC connectors are reserved for front file serving into a client network (shown in black).
