Configuring LLT over RDMA for Veritas Access
During the Veritas Access installation, the installer automatically configures LLT over RDMA if there are InfiniBand NICs on the cluster nodes, unless the InfiniBand NICs are excluded.
This section describes the required hardware and configuration for LLT to support RDMA for Veritas Access. The high-level steps to configure LLT over RDMA are as follows:
1. Choose NICs, network switches, and cables that support RDMA.
Table: RDMA-enabled hardware
Hardware | Supported types | Reference |
---|---|---|
Network card | Mellanox-based Host Channel Adapters (HCAs) (VPI, ConnectX, ConnectX-2 and 3) | For detailed installation information, refer to the hardware vendor documentation. |
Network switch | Mellanox, InfiniBand switches Ethernet switches must be Data Center Bridging (DCB) capable | For detailed installation information, refer to the hardware vendor documentation. |
Cables | Copper and Optical Cables, InfiniBand cables | For detailed installation information, refer to the hardware vendor documentation. |
2. Connect the first two non-excluded InfiniBand NICs as private NICs.
Note:
Cross-links connection is not supported for private NICs in an RDMA environment.
3. Make sure that the required packages to enable RDMA, InfiniBand drivers, and utilities are installed with the base operating system. Or they can be installed from the yum repository.
