25 Gbps Ethernet host interface adapter ports and indicators

You can install optional 2-port 25 Gbps Ethernet host interface adapters for your Storwize® V7000 Gen2+ (Storwize V7000 2076-624) system.

The system can support 2-port 25 Gbps host interface adapters that use either the RDMA over Converged Ethernet (RoCE) networking protocol or the iWARP (Internet Wide-area RDMA Protocol) networking protocol. Each host interface adapter is used for Internet Small Computer System Interface (iSCSI) connections to host systems. The ports cannot be used for system management. The Small Form-factor Pluggable (SFP) transceivers that are installed on the adapter support data transfer speeds of 25 Gbps.

As Figure 1 shows, the 25 Gbps host interface adapters can be installed in slots 2 and 3 of each node canister.

25 Gbps Ethernet host interface adapter indicators

Each port on the 2-port 25 Gbps Ethernet host interface adapter has one bi-color LED that indicates the status of the link and port. The location of the LEDs varies, depending on the type of adapter.

Figure 2 shows the front of a 2-port 25 Gbps Ethernet (RoCE) host interface adapter.

The LED states and their meanings are explained in Table 1.

Table 1. LED indicators for 25 Gbps Ethernet host interface adapter (RoCE)
Color	State	Meaning
None	Off	The port is not active.
Green	Solid	The port has a valid link with no active traffic.
Green	Blinking	The port has a valid link with active traffic.
Yellow	Blinking	Indicates a problem with the link.

Figure 3 shows the 25 Gbps Ethernet (iWARP)host interface adapter. Each port has a single LED that indicates the status of the port and link.
