2-1 Overview of Network Configuration
HP StorageWorks XP Series disk arrays come equipped with a service processor, which is known as
the SVP. The SVP has two Ethernet adapters. The first adapter is for a private (internal) Ethernet
LAN, which is intended for intra-array communications only. There are only two devices that can
access the internal LAN: the Service Processor (SVP) and the Remote Console for XP512/XP48.
The second adapter is used for other applications to talk to the SVP. This LAN is referred to as the
public LAN, because it is visible to other computers outside the array. The XP12000/XP10000 and
XP1024/XP128 Remote Web Console, Command View XP AE Device Manager, Enterprise Resource
Manager and Enterprise Storage Resource Manager applications use the public LAN to communicate
with the SVP about the array and configuration changes.
CAUTION: HP StorageWorks XP Series disk arrays have a public LAN and a private LAN. Device Manager
uses the public LAN to communicate with the SVP about the array and configuration changes. Do not under
any circumstances attach the private LAN to an external network because this can cause serious problems
on the array.
Figure 2-1 illustrates an incorrect LAN connection.
