Planning the Fabric
TCP/UDP/IP
Chapter 214
TCP/UDP/IP
TCP/UDP/IP is supported on all HF2 hardware. Although some of the
HyperFabric adapter cards support both HMP and TCP/UDP/IP
applications, in this section, the focus is on TCP/UDP/IP HyperFabric
applications.
Application Availability
All applications, including Oracle 9i and HP-MPI, that use the
TCP/UDP/IP stack are supported.
Features
This section discusses the following HyperFabric features on
TCP/UDP/IP:
• OnLine Addition and Replacement (OLAR): Supported
The OLAR feature allows the replacement or addition of
HyperFabric adapter cards while the system (node) is running.
HyperFabric supports this functionality on the SD64A, rx8620,
rx4640, rp54xx (L-class), rp74xx (N-class), rp8400 and Superdome
systems, running on the HP-UX 11i v2 platform.
For more information on OLAR, including instructions for
implementing this feature, see “Online Addition and Replacement”

B2355-90698 November 2000 Edition.
• Event Monitoring Service (EMS): Supported
In the HyperFabric version B.11.23.01, the HyperFabric EMS
monitor enables the system administrator to separately monitor
each HyperFabric adapter on every node in the fabric, in addition to
monitoring the entire HyperFabric subsystem. The monitor can
inform the user if the resource being monitored is UP or DOWN. The
administrator defines the condition to trigger a notification (usually
a change in interface status). Notification can be accomplished with
one of the following:
— A Simple Network Management Protocol (SNMP) trap
