Info

C–VirtualNIC Interface Configuration and Administration VirtualNIC Interface Configuration and Administration IB_MULTICAST Defaults to TRUE. The InfiniBand multicast parameter can be set to either TRUE or FALSE. When the parameter is set to true, it will take effect only if the corresponding CLI command (ethVirtVnic2Mcastset) is executed on the EVIC. This command is supported on EVIC FW 4.3 and above.

D SRP Configuration SRP Configuration Overview SRP stands for SCSI RDMA Protocol. It allows the SCSI protocol to run over InfiniBand for Storage Area Network (SAN) usage. SRP interfaces directly to the Linux file system through the SRP Upper Layer Protocol (ULP). SRP storage can be treated as another device. In this release, two versions of SRP are available: QLogic SRP and OFED SRP. QLogic SRP is available as part of the QLogic OFED Host Software, QLogic InfiniBand Fabric Suite, Rocks Roll, and Platform PCM downloads. SRP has been tested on targets from DataDirect Networks and Engenio (now LSI Logic ® ). NOTE: Before using SRP, the SRP targets must already be set up by your system administrator. Important Concepts • A SRP Initiator Port is a adapter port through which the host communicates with a SRP target device (e.g., a Fibre Channel disk array) via a SRP target port. • A SRP Target Port is an IOC of the VIO hardware. In the context of VIO hardware, an IOC can be thought of as a SRP target. An FVIC contains 2 IOCs. IOC1 maps to the first adapter on the FVIC, and IOC2 maps to the 2nd adapter on the FVIC. On an FCBM, there are also 2 IOCs, and IOC1 maps to port 1 of the adapter of the FC BM and IOC2 maps to port 2 of the adapter of the FC BM. • A Fibre Channel Target Device is a device containing storage resources that is located remotely from a Fibre Channel host. In the context of SRP/VIO hardware, this is typically an array of disks connected via Fibre Channel to the VIO hardware. D000046-005 B D-1
