Duplex LAN Configuration
The operable network configuration is described here.
3.1
Functional Overview
Duplicating a LAN is achieved by binding multiple adapters to the same virtual switch (NIC teaming). If an uplink
adapter fails, it switches to another adapter to continue the operation.
3.2
Operable Network Configuration
For NEC Express5800/ft series, network interface names are based on the naming convention as described in
the table below. Network duplication is achieved by pairing network interfaces of PCI slots in CPU/IO module 0
and network interfaces in the same PCI slots in CPU/IO module 1 (i.e. Two network interfaces are bound to a
switch).
When installing ESXi, the standard switch (vSwitch0) is created in the port #1 (vmnic_100600, vmnic_110600)
of On Board (1 Gigabit) of CPU/IO modules 0 and 1, and network duplication is achieved.
You can configure the setting of and check the network interfaces from vSphere Client.
For more specific setting method, see VMware vSphere document “
ESXi Configuration Guide
”.
The network may be disconnected for up to about one minute when failover occurs on CPU/IO module due to
hardware failure.
It is necessary to be used after carefully examining the setting of application and client.
When I/O modules 0 (10) and 1 (11) were duplexed after startup of ESXi host, an alert is issued to NEC
ESMPRO Manager.
[Message: The device is now in a DUPLEX state.]
After this alert is issued, the following alert may be issued for the device such as network adapter of which
status is changed to SIMPLEX.
[Message: The device is now in a SIMPLEX state.]
However, it is not the problem if an alert that notifies of completion of duplication is issued immediately after this
alert message.
