An InfiniBand fabric consists of one or more InfiniBand switches connected via inter-switch links. The most commonly deployed fabric topology is a fat tree or its variations. A subnet manager is required to manage and control an InfiniBand fabric. The subnet manager functionality can be provided by either a rack-mount InfiniBand switch with an embedded fabric manager (aka internally managed switch) or host-based subnet manager software on a server connected to the fabric. OpenSM is a host-based subnet manager that runs on a server connected to the InfiniBand fabric. Mellanox OFED software stack includes OpenSM for Linux, and Mellanox WinOF includes OpenSM for Windows. For comprehensive management and monitoring capabilities, Voltaire Unified Fabric Manager™ (UFM) is recommended for managing the InfiniBand fabric based on Voltaire InfiniBand switch products and Mellanox ConnectX-based mezzanine HCA running Voltaire OFED stack.

Embedded fabric manager is available on Voltaire internally managed 36-port 4X QDR switch, 24-port, 96-port, and 288-port DDR switches. Please refer to: http://h18000.www1.hp.com/products/quickspecs/13078_na/13078_na.html for information about InfiniBand rack switches.

The following InfiniBand products based on QLogic technology are available for the HP BladeSystem c-Class from HP:

• QLogic 4X QDR IB Mezzanine HCA for HP BladeSystem c-Class

The QLogic 4X QDR IB Mezzanine HCA is based on the QLogic TrueScale ASIC architecture which has a unique hardware architecture that delivers unprecedented levels of performance, reliability, and scalability, making it an ideal solution for highly scaled High Performance Computing (HPC) and high throughput, low-latency enterprise applications.

InfiniBand host stack software (driver) is required to run on servers connected to the InfiniBand fabric. For HCAs based on QLogic technology, HP supports QLogic OFED driver stacks on Linux 64-bit operating systems.

The QLogic BLc 4X QDR IB Switch for HP BladeSystem c-Class uses the QLogic TrueScale ASIC architecture designed to cost-effectively link workgroup resources into a cluster or provide an edge switch option for a larger fabric. Customers have the ability to internally or externally manage the modular IB switch. The QLogic BLc 4X QDR IB Switch also has an optional management module that includes an embedded subnet manager. This management module is an option for both the 32-port QDR BladeSystem switch and the 36-port QDR edge switch. When combined with the optional InfiniBand Fabric Suite software, users can mange up to a 288 node fabric using only the management capability of the unit, without requiring additional host processing. In a bladed environment this alleviates the need to use a node for fabric management.

An InfiniBand fabric is constructed with one or more InfiniBand switches connected via inter-switch links. The most commonly deployed fabric topology is a fat tree or its variations. A subnet manager is required to manage an InfiniBand fabric. OpenSM is a host-based subnet manager that runs on a server connected to the InfiniBand fabric. QLogic OFED software stack includes OpenSM for Linux.
