Migrating from HyperFabric to other interconnect solutions such as Infiniband and Gigabit/10-Gigabit Ethernet

• /var/adm/clic_log.old
The backup copy of the log file that is created when the log file grows larger than 100 Kbytes.
• /var/adm/OLDclic_log
The log file from the previous time the clic_start command was executed.
• /usr/conf/lib/libclic_dlpi_drv.a
The kernel library that contains the HyperFabric software.
• /usr/conf/lib/libha_drv.a
The kernel library that contains the High Availability (HA) software.
• /usr/conf/master.d/clic
This file is described along with the other master files in the master man page (type man master at
the HP-UX prompt).
• Remove the subdirectories under /opt/clic such as share, bin, firmware, include, and lib.
• /opt/clic/lib/libclic_mgmt.a
The Hyper Fabric management API library.
• /opt/clic/bin
The directory containing the HyperFabric management commands: clic_diag, clic_init,
clic_probe, clic_shutdown, clic_start, clic_stat, and clic_dump. Also,
clic_ping is replaced by clic_probe. This directory also contains the HyperFabric
management process (clic_mgmtd) and the HyperFabric EMS monitor process (clic_mond).
Cluster Interconnect options beyond HyperFabric
Apart from HyperFabric, HP has other clustering interconnect solutions like InfiniBand and 10
Gigabit/Gigabit Ethernet which are used by customers who are looking for a more competitive and
industry standard clustering interconnect technology on HP-UX platforms. The following sections
discuss these products.
InfiniBand
InfiniBand is supported by HP Fabric Clustering System as a fabric for high-performance technical
computing clusters and as a fabric for commercial database clusters. InfiniBand is a switched I/O
fabric architecture. It was created to meet the increasing demands of the data center, and allows data
centers to harness server computing power by delivering an I/O fabric that provides reliable low
latency communication both from one server to another server, and between server and their shared
I/O resources.
InfiniBand technology refers to both a communications and management infrastructure that increases
the communication speed between CPUs, devices within servers, and subsystems located throughout a
network. It defines a switched communications fabric that allows many devices to concurrently
communicate with high-bandwidth and low latency in a protected, easily managed environment.
Advantages of Infiniband
Infiniband addresses four problems:
• Application to application latency
• Application CPU consumption
