You use the USB-Key InitTool  to set up the cluster IP address. You must set the two service IP addresses after the system is installed. Record the cluster and service IP address settings for the storage enclosure in Table 3-3.

## 3.2.2 Interface card connections 

This section describes the information that is needed for various interface card connections and for the connection switches. 

Important:  Each host must be connected to both canisters to add redundancy and improve performance. If a host is not connected to both canisters, its state shows as degraded. 

## Fibre Channel 

Each canister supports the following optional Fibre Channel (FC) interface cards: 

GLYPH<SM590000> 16 Gb FC cards supporting either two 16 Gb FC optics in the two leftmost ports on the card (ports 1 and 2 in Table 3-4 on page 79) or four 8 Gb FC optics/ports 

GLYPH<SM590000> 16 Gb FC-NVMe cards supporting four 16 Gb FC optics/ports 

Important:  Small form-factor pluggable (SFP) transceivers must be obtained and deployed in pairs to support multipathing. 

In order to use FC-NVMe make sure your SAN infrastructure is supporting this protocol. 

For a more detailed description of the options on interface cards and optics, see Chapter 5, “Non Volatile Memory express” on page 133.
