multiple Subnet Managers, but only one master. HP supports the use of an SM on the switch.
About the HP Fabric Clustering System Software Suite
The HP Fabric Software Suite supports the following upper-layer protocols: MPI and IPoIB.
Oracle 10gRAC is also supported.
MPI
MPI stands for Message-Passing Interface, an industry standard for developing portable
message-passing applications. HP MPI provides developers of technical applications with an
application programming interface (API) and software library to support parallel, message-passing
applications that are efficient, portable and flexible.
For more information on HP MPI, consult http://www.hp.com/go/mpi.
IPoIB
For more information on IPoIB, consult http://www.ietf.org/html.charters/ipoib-charter.html.
IPoIB allows IP applications to utilize the HP Fabric. IPoIB is configured like a normal Ethernet
interface. During the installation process, IPoIB interfaces are automatically added to the network
configuration. These interfaces correspond to the ports on the HCA.
Oracle 10gRAC
Oracle Corporation's clustered database.
For more information on 10gRAC, consult http://www.oracle.com and http://www.hp.com/go/oracle.
SKGXP
Middleware layer used by Oracle 10gRAC.
Itutil
The HP-UX Interconnect Transport utility, itutil, is a CLI (command line interface) to administer
and manage HP-UX RDMA infrastructure and HP Fabric.
IT-API
The Interconnect Transport API, IT-API, is an industry standard API for RDMA-capable transports
including InfiniBand.
For more information on IT-API, consult http://www.opengroup.org/icsc.
