Supported Features
The following are HP Fabric Clustering System features:
Diagnostics: Supported You can run diagnostics to obtain information on many of
the HP Fabric Clustering System components using the
itutilcommand. For a more about the itutil
command, see “Using Itutil” (page 56)
For information on HP Fabric switch diagnostics, see
“Troubleshooting the HP Fabric Network” (page 126).
OnLine Addition and Replacement
(OL*): Limited Support
On-Line Addition and Replacement (OL*) of HP Fabric
adapters is supported on HP Fabric Clustering System
version B.11.23.02 or newer with a couple of limitations
related to replacing an HP Fabric HCA, see “Replacing an
HP Fabric Clustering System HCA (HP-UX 11i v2 only)”
(page 39) for details.
Serviceguard: Supported Serviceguard is supported with IPoIB. See “Configuring
IPoIB Interfaces for Serviceguard Clusters” (page 72) for
details. Within a cluster, Serviceguard groups application
services (individual HP-UX processes) into packages.
Configuration Parameters
This section discusses the limits for HP Fabric Clustering System configurations. There are
numerous variables that can impact the performance of any particular configuration. For more
information on specific configurations for applications, see “Supported Configurations” (page 52).
HP Fabric Clustering System is supported on many HP servers. For the latest list of supported
servers, see the HP Fabric Clustering System Support Matrix on http://www.docs.hp.com in the I/O
Cards and Networking Software section under Fabric Clustering System for InfiniBand.
Maximum Supported Nodes and Adapter Cards (AB286C)
A maximum of 8 fabric 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.
Maximum Number of Switches You can interconnect (mesh) two 24-port copper switches
in a single cluster. HP recommends only meshing a
maximum of two 24-port copper switches. A subsequent
software release may support more switches or a switch
with a higher port count in order to accommodate more
