Enterprise

Worldwide

The 100 Gbit/s RDMA interface module is used to connect a controller enclosure to another controller enclosure or a smart disk enclosure.

Function

A 100 Gbit/s RDMA interface module provides two 100 Gbit/s optical ports.

Figure 4-123 and Figure 4-124 show the appearances of 100 Gbit/s RDMA interface modules. SO stands for scale-out and BE stands for back-end.

Table 4-50 describes the indicators on a 100 Gbit/s RDMA interface module after the storage system is powered on.

Table 4-50 Indicators on a 100 Gbit/s RDMA interface module

Indicator	Status and Description
Module Power indicator	Steady green: The interface module is working correctly. Blinking green: There is a hot swap request to the module. Steady yellow: The module is faulty. Off: The module is powered off or hot swappable.
Port Speed indicator	Steady blue: The speed is the highest. Blinking blue (2 Hz): The port is transmitting data at the highest speed. Steady yellow: The optical module or cable is faulty or not supported by the port. Off: The link to the port is down.
