Configure iSER on your ESXi host, so that the iSCSI framework on the host can use the Remote Direct Memory Access (RDMA) transport instead of TCP/IP.
When installed on the host, the RDMA-capable adapter appears in vCenter Server as a network adapter (vmnic).
To make the adapter functional, you must enable the VMware iSER component, and then connect the iSER adapter to the RDMA-capable vmnic. You can then configure typical properties, such as targets and CHAP, for the iSER adapter.
The entire setup and configuration process for the iSER adapters involves several steps.
|Enable the VMware iSER Adapter
|Use the esxcli command to enable the VMware iSER adapter.
|Modify General Properties for iSCSI or iSER Adapters
|If needed, change the default name and alias assigned to your adapter.
|Configure Port Binding for iSCSI or iSER
|You must create network connections to bind the iSER engine and the RDMA-capable network adapter. The process of configuring these connections is called port binding.
Note: iSER does not support NIC teaming. When configuring port binding, use only one RDMA adapter per vSwitch.
|Configure Dynamic or Static Discovery for iSCSI and iSER
|Set up the dynamic discovery. With the dynamic discovery, each time the initiator contacts a specified iSER storage system, it sends the SendTargets request to the system. The iSER system responds by supplying a list of available targets to the initiator. In addition to the dynamic discovery method, you can use the static discovery and manually enter information for the targets.
|Set Up CHAP for iSCSI or iSER Adapter
|If your environment uses the Challenge Handshake Authentication Protocol (CHAP), configure it for your adapter.
|Set Up CHAP for Target
|You can also configure different CHAP credentials for each discovery address or static target.
|Enable Jumbo Frames for Networking
|If your environment supports Jumbo Frames, enable them for the adapter.
