This information provides planning and installation information
to help guide you through the process of installing a cluster fabric
that incorporates InfiniBand switches.
IBM® server hardware
supports clustering through InfiniBand host channel
adapters (HCAs) and switches. Information about how to manage and
service a cluster by using InfiniBand hardware
is included in this information.
The following figure
shows servers that are connected in a cluster configuration with
InfiniBand switch networks
(fabric). The servers in these networks can be connected through switches
that use IBM GX HCAs. In
System p® Blade servers, the
HCAs are based on
PCI Express™ (
PCIe).
Notes: - Switch refers to the InfiniBand technology
switch unless otherwise noted.
- Not all configurations support the following network configuration.
See your IBM sales information
for supported configurations.
