Network ports

The network ports transmit and receive data communications between the appliance and external sources.

Network ports are grouped and located by function.
  • Two fixed management Ethernet ports.
  • Two fixed 10 Gb small-form-factor pluggable SFP+ ports.
  • One removable 1 Gb Ethernet module with eight ports for the RJ45 interface.
  • One removable 10 Gb Ethernet module with four SFP+ ports.
  • Two removable 40 Gb Ethernet modules, each with two QSFP+ ports.

Management Ethernet ports

The management Ethernet ports provide remote management access to the appliance and should not be used as data ports. Use the ports in the Ethernet modules for handling data traffic.

Consider management traffic in the overall availability, network, and management plan for the deployment. Management traffic, with the exception of IPMI, is not fundamentally different than any other kind of traffic the appliance processes. The same techniques that separate network zones apply equally to management traffic.

mgt0
This Ethernet interface can manage all management data. This port also supports IPMI over LAN, which includes serial over LAN.
mgt1
This Ethernet interface can manage all management data. This port also supports IPMI over LAN, which includes serial over LAN.

10 Gb Ethernet ports

The appliance has two 10 Gb small-form-factor pluggable SFP+ ports that are part of the appliance. The SFP+ ports support optical or electrical interfaces with the appropriate transceiver. These two ports are functionally the same with the ports in the 10 Gb Ethernet module.

Ethernet modules

The appliance has three Ethernet modules for network connectivity. The right module contains eight 1 Gb Ethernet ports. The middle modules contain four 40 Gb Ethernet ports. The left module contains four 10 Gb Ethernet ports.

1 Gb Ethernet module
Has eight RJ45 Ethernet ports. The Ethernet ports are placed in two rows. The numbering start with 10 and are sequential from lower-left to upper-right. Each port has an associated speed LED and activity LED. The speed and activity LEDs on the lower and upper rows have opposite orientation.

10 Gb Ethernet module
Has four 10 Gb SFP+ ports. The numbering start with 20 and are sequential from left to right. Each port has an associated activity LED. By default, eth20 is used for the replication link in a disaster recovery configuration and eth21 is used for the replication link in a high availability configuration.

40 Gb Ethernet modules
Has two 2 x 40 Gb QSFP+ ports. They are numbered 30, 31, 32, 33 respectively. Each port has an associated activity LED.

Each 40 Gb Network module provides a total of 40Gb of bandwidth that is shared between the two physical ports on that module. You can create an aggregate interface using one physical connection to each network module (for example, eth30 and eth32) to boost total bandwidth and the availability characteristics of the link.
