Audience This Document is intended for customers who have their cluster interconnect solutions on HyperFabric/HyperFabric2 and are looking to migrate from HyperFabric to other cluster interconnect options such as Infiniband and Gigabit or 10-Gigabit Ethernet. HyperFabric/HyperFabric2 HyperFabric is an HP high-speed, packet-based interconnect for node-to-node communications.

Removing HyperFabric on HP9000 and Integrity servers This section discusses the procedure to remove HyperFabric from a HP9000 server. You can follow the same procedure to remove HyperFabric from HP Integrity servers and for HP-UX 11iv3. Login as root and complete the following steps: 1. Run the following command to halt all HyperFabric processes #opt/clic/bin/clic_shutdown 2. Find the HyperFabric software with the following command #swlist |grep hyper 3.

• /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.

• • Network bandwidth Fabric Management Capabilities of InfiniBand InfiniBand is a standard-based interconnects that enables the following: • High-bandwidth, 10 Gbps connectivity. With PCIe, it provides 20Gbps in each direction.
PAGE 6
• Rapid and flexible deployments requiring minimal training, due to leveraged Ethernet knowledge Key performance and manageability features/benefits include • • • • • • • Substantial bandwidth in one large pipe; 10GbE can be as an uplink to overcome existing Gigabit Ethernet bottlenecks TCP Segmentation Offload (TSO) and Checksum Offload (CKO) allow segmentation and error checking to be handled by the adapter itself; thus saving CPU cycles when sending large amounts of data over the network Jumbo fram
