The HP IB 4X DDR HCA connects to the InfiniBand fabric through the HP 4X DDR IB Switch Module.
Both of these devices are configured for DDR operation, therefore the mezzanine cards will always
operate at DDR rates.
The Switch Modules external ports will negotiate down to SDR speeds if they are connected to a device
which can not operate at DDR.
Self-discovery is supported by Subnet Manager. Check the documents of specific subnet manager used
to manage the InfiniBand fabric.

For the mezzanine, configuration and management can be handled through the PCI Express interface or
in-band through the InfiniBand fabric.
HP HPC IB 4X DDR HCA (part number 409377-B21) shipped with Voltaire® GridStack includes drivers
and utilities to configure and manage the HCA in Linux and Windows CCS environments.
HP Cisco IB 4X DDR HCA (part number 438670-B21) shipped with Cisco IB drivers that are supported
in Linux environments.
The HP 4X DDR IB HCA (part number 410533-B21) does not ship with any driver software and it is
intended to use open source software: see OFED support discussion above for more details.
The Switch Module is an unmanaged switch, meaning that management for the InfiniBand fabric must
be provided by either a rack-mount internally managed switch or by a subnet manager software running
on a server in the fabric.
InfiniBand fabric has to be set up with a subnet manager. When a Voltaire internally managed Grid
switch product is used, the GridVision subnet manager runs on the embedded processor on the switch.
The fabric manager can also be provided by using Cisco SFS 7000D 24-port switch. The Voltaire fabric
manager and Cisco fabric manager do not interoperate.
OpenSM can also be used to establish an InfiniBand fabric; however, customer has to work with
OpenFabrics community for the support of OpenSM.
