Portal network
Review these network considerations to help you set up the network in your datacenter to use Lenovo XClarity One as a virtual machine.
To configure network settings, click Portal configuration on the context menu from the Settings view.
Network interface (eth0)
- The network interface is used for discovery and management. XClarity One must be able to communicate with all hubs and devices that you intend to manage.
- Some functions require an Internet connection, preferably through a firewall. If the network interface is not connected to the Internet, those functions will not work.
IPv4 address settings
XClarity One uses IPv4 network settings. You can configure the IP assignment method, IPv4 address, network mask, and default gateway.
For the IP assignment method, you can choose to use a statically-assigned IP address or obtain an IP address from a Dynamic Host Configuration Protocol (DHCP) server. When using a static IP address, you must provide an IP address, network mask, and default gateway. The default gateway must be a valid IP address and must be on the same subnet as the network interface.
If DHCP is used to obtain an IP address, the default gateway also uses DHCP.
- IPv6 addresses are not supported.
- Network address translation (NAT), which remaps one IP address space into another, is not supported.
- Changing the IP address of the XClarity One virtual-appliance after the portal is up and running will cause connectivity issues with the management hubs. If you need to change the IP address, disconnect management hubs from the portal. After the IP address change is complete, reconnect management hubs to the portal..
- If the network interface is configured to use the DHCP, ensure that IP address changes are minimized by basing the DHCP address on a MAC address or configuring DHCP so that the lease does not expire to avoid communication issues. If the IP address changes when the DHCP lease expires, you must disconnect (delete) the management hub from the portal, and then connect it again.
DNS settings
XClarity One uses IPv4 network settings. You can configure the IP assignment method, up to two static DNS IPv4 addresses, and custom host name and domain.
For the IP assignment method, you can choose to use a statically-assigned IP address or obtain an IP address from a DHCP server. When using a static IP address, you must provide an IP address for at least one and up to two DNS servers.
Specify the DNS host name and domain name. You can choose to retrieve the domain name from a DHCP server or specify a custom domain name.
Firewalls
Ensure that the following DNS names and ports are open on the firewall for XClarity One and management hubs. Each DNS represents a geographically distributed system with a dynamic IP address.
| DNS name | Ports | Protocols | Description |
|---|---|---|---|
| soaus.lenovo.com | 443 | https | Create a service ticket with Lenovo Support (Call Home) |
| esupportwebapi.lenovo.com | 443 | https | Send service data to Lenovo Support (Call Home) |
| supportapi.lenovo.com | 443 | https | Retrieve warranty information |
| support.lenovo.com | 443 | https | Retrieve firmware catalog information from Lenovo |
Open ports
If management hubs are behind a firewall and if you intend to manage those hubs from an XClarity One instances that is outside of that firewall, you must ensure that all ports involved with communications between the XClarity One portal and each management hub are open.
If devices are behind a firewall and if you intend to manage those devices from a management hub that is outside of that firewall, you must ensure that all ports involved with communications between the management hub and the baseboard management controller in each device are open (see Configuring the management hub network).
