Learn the overview for configuring the network for Lenovo Converged System.
Note: The initial configuration of your Lenovo Converged System is performed
by the Services Team and is included with your purchase. To ensure
initial configuration success, it is important that you do not change
the default shipped configuration until these services are complete.
The Lenovo Converged System configuration
5V with feature code ETS2 and configuration 7V come with three networks,
each of which is isolated from the others by Virtual LAN (VLAN) assignment
within the Ethernet switches. Your view to each network is through
one or more "uplink" ports, which are untagged. (That is, the frames
that are coming out of those ports do not have any IEEE 802.1q VLAN
tags, and incoming untagged frames are automatically sent to the right
network.) The networks can be differentiated by the color of the cabling
used: Green, Purple, and Gold.
- Green network
- The green network is for your data and it is assigned to VLAN
4092. There are no IP addresses assigned to this network in manufacturing,
so you can assign them to meet your needs.
- Purple network
- The purple network is assigned to VLAN 4091. All entities on the
purple network are assigned IPv4 addresses within the 10.91.0.0/16
network (that is, 10.91.*.* with netmask 255.255.0.0). This address
is the network where you access the Flex System Manager node on
its external Ethernet (eth1) interface. You can also directly access
the following nodes:
- The ESXi hypervisor on X-Architecture compute nodes
In addition, any guest operating systems that you want to manage
by using the Flex System Manager must
have an IP address on this network.
- Gold network
- The gold internal device management network is assigned to VLAN
4093 on single-chassis systems without any top-of-rack switches, and
is entirely isolated on the top-of-rack switches, if present. This
network contains the following endpoints:
- The internal Ethernet (eth0) interface on the Flex System Manager node
- The chassis management modules
(CMMs)
- The management interfaces for any Ethernet or SAN switches
- The integrated management modules (IMMs) of X-Architecture compute
nodes
- The Storwize V7000 management
interfaces
Each of these endpoints is assigned a fixed IPv4 address on the
192.168.93.0/24 network (that is, 192.168.93.* addresses with netmask
255.255.255.0), and an IPv6 Unique Local Address (ULA) that will not
to conflict with any address on the customer's network. The Flex System Manager node manages
all of these endpoints by using the IPv6 addresses, so you can choose
to reassign the IPv4 addresses as wanted to fit into your network.
As noted above, the Flex System Manager is able
to communicate on both the purple and gold networks.
