Planning the Fabric

TCP/UDP/IP

Chapter 2 17

Switch Management is not supported. Switch management will not

operate properly if you enable it on a HyperFabric cluster.

• Diagnostics: Supported

Diagnostics can be run to obtain information on many of the

HyperFabric components using the clic_diag, clic_probe and

clic_stat commands, as well as the Support Tools Manager (STM).

For more information on HyperFabric diagnostics, see “Running

Diagnostics” on page 133.

Conﬁguration Parameters

This section describes the maximum limits for TCP/UDP/IP HyperFabric

conﬁgurations. There are numerous variables that can impact the

performance of any HyperFabric conﬁguration. For guidance on speciﬁc

HyperFabric conﬁgurations for TCP/UDP/IP applications, see the

section, “TCP/UDP/IP Supported Conﬁgurations” on page 21.

• HyperFabric is supported only on the HP 9000 series servers and

workstations.

• TCP/UDP/IP is supported for all HyperFabric hardware and

software.

• Maximum Supported Nodes and Adapter Cards

In point-to-point conﬁgurations, the complexity and performance

limitations of having a large number of nodes in a cluster make it

necessary to include switching in the fabric. Typically, point-to-point

conﬁgurations consist of only 2 or 3 nodes.

In switched conﬁgurations, HyperFabric supports a maximum of 64

interconnected adapter cards.

A maximum of 8 HyperFabric adapter cards are supported per

instance of the HP-UX operating system. The actual number of

adapter cards a particular node is able to accommodate also depends

on slot availability and system resources. See node speciﬁc

documentation for details.

HyperFabric subsystem supports a maximum of 8 conﬁgured IP

addresses per instance of the HP-UX operating system.
