„A subset of the QLogic InfiniBand Fabric Suite, the enablement tools, are offered with this release.

„Two separate SCSI RDMA Protocol (SRP) modules are provided: the standard OpenFabrics (OFED) SRP, and QLogic SRP.

„QLogic MPI supports running exclusively on a single node without the installation of the HCA hardware.

„OpenMPI and MVAPICH libraries built with the GNU, PGI, PathScale™, and Intel® compilers are available, with corresponding mpitests RPMs. You can use mpi-selectorto choose which MPI you want. These all run over PSM.

„4K Maximum Transfer Unit (MTU) is supported and is on by default. To take advantage of 4KB MTU, use a switch that supports 4KB MTU. QLogic also supports 2KB switches, and 4KB MTU switches configured for 2KB MTU.

QLogic switches with firmware version 4.1 or later are recommended.

„The Lustre® cluster filesystem is supported.
