HP StorageWorks Multi-protocol Router Installation Guide (A7437-96003, September 2005)

Overview18
Software features
XPath OS 7.4.x runs on the MP Router. The firmware provides full Fibre Channel switch capability,
FC-FC Routing Service, and Fibre Channel over IP tunneling.
You can configure individual ports on the MP Router to support the switch functionality or services
that you need.
Fibre Channel switch support
XPath OS 7.4.x includes the following Fibre Channel features:
• Name Server support
• Zone Server support
• ISL exchange-based trunking
See the
HP StorageWorks XPath OS 7.4.x administrator guide for additional information on these
features.
Multi-protocol SAN routing services
Multi-protocol SAN routing services are available on the MP Router. These services include the
FC-FC Routing Service, iSCSI Gateway Service, and the FCIP Tunneling Service.
FC-FC Routing service
The FC-FC Routing Service provides connectivity to devices in different fabrics without merging the
fabrics. A major component of this service is the MP Router. It allows data to flow across it while it
controls the visibility of devices behind it. FC-FC routing allows the creation of Logical Storage Area
Networks (LSANs). An LSAN can span multiple fabrics, allowing Fibre Channel zones to cross
physical SAN boundaries without merging the fabrics yet still maintaining access control of the
zones. FC-FC routing also allows you to share devices, such as tape drives, across multiple fabrics
without the potential administrative problems that sometimes result from merging the fabrics.
See the
HP StorageWorks XPath OS 7.4.x administrator guide for additional FC-FC routing
information.
iSCSI Gateway service
The iSCSI Gateway service provides connectivity to Fibre Channel targets for servers using iSCSI.
Servers use an iSCSI adapter or an iSCSI driver and Ethernet adapter to connect to a Fibre Channel
fabric over IP. See the
HP StorageWorks XPath OS 7.4.x administrator guide for additional iSCSI
Gateway information.
