Networking considerations

Networking issues to consider when planning for your Lenovo ThinkAgile CP installation.

You need to consider the following topics before proceeding with the installation of the ThinkAgile CP solution.

System network cables

ThinkAgile CP delivers with network cables having lengths to enable installation of all equipment in the stack into a single customer rack.

  • Cables - ThinkAgile CP can be ordered with optional cables for uplinks to the customer's data center network. If these cables are insufficient, plan the correct cable types and lengths with the customer.

  • Adapters - ThinkAgile CP can be ordered with optional adapters to provide an uplink to the customer's data center through the solution interconnects. You must plan and purchase additional adapters for the customer's existing data center network hardware.

  • Routes - prior to installation, the customer must decide on the routing protocol used to connect to the data center network, and must configure the routes on the hardware connected to the ThinkAgile CP interconnect.

Pre-install network configuration

The following figure provides an overview of the network planning to be performed before the installation of ThinkAgile CP.

VLANs

  • Prior to installation, the customer must provide a list of VLANs to trunk into the ThinkAgile CP network.

  • We recommend trunking VLANs into the ThinkAgile CP network during the initial setup process.

IP address ranges

  • Prior to installation, the customer must provide at least one IP address range for use by the ThinkAgile CP system to automate IP address allocation.

  • We recommend assigning one or more dedicated class B or class C networks to ThinkAgile CP.

Firewall rules

  • Prior to installation, the customer must configure their network firewall settings to allow the ThinkAgile CP system access to the internet. This is required for some functions to properly work.

  • We recommend configuring both outgoing and incoming firewall rules.
