TCP/IP requirements for Lenovo Storage V7000

Plan your installation, considering TCP/IP address requirements and service access.

To plan your installation, use Table 1 and consider the TCP/IP address requirements of the Lenovo Storage V7000clustered system and the requirements for the Lenovo Storage V7000 to access other services. You must also plan for the Ethernet address allocation, and for the configuration of the Ethernet router, gateway and firewall.

Figure 1 shows the TCP/IP ports and services that are used by Lenovo Storage V7000.

Both IPv4 and IPv6 addresses are supported. Lenovo Storage V7000 can operate with either internet protocol or with both internet protocols concurrently.

For configuration and management, you must allocate an IP address to the system, which is referred to as the management IP address. For additional fault tolerance, you can also configure a second IP address for the second Ethernet port on the node.The addresses must be fixed addresses. If both IPv4 and IPv6 are operating concurrently, an address is required for each protocol.

Note: Lenovo Storage V7000 Gen1 models 2076-312 and 2076-324 have two 10 Gbps Ethernet ports per node canister, numbered ports 3 and 4. The 10 Gbps ports can only be used for iSCSI or Fibre Channel over Ethernet host attachment. They cannot be used for configuration or management. A Lenovo Storage V7000 Gen2 model 2076-524 can have up to eight 10 Gbps Ethernet ports per control enclosure when two 4-port 10 GbE host interface adapters are installed.

In addition to the management IP addresses, the system is configured with one or more service IP addresses.Service IP addresses are used to gain access to the service assistant when a node is not operating correctly as part of the system. As with the management IP addresses, service IP addresses can be IPv4 addresses, IPv6 addresses, or both. You should choose a fixed IP address per Ethernet port, or you can configure Lenovo Storage V7000 to use a DHCP-allocated address.

Attention: The address for a management IP cannot be the same address that is used for the service IP. Using the same IP address causes an error.

Any system that accesses the service IP address must be able to access a management IP address, or a dynamically-allocated service address if DHCP is used.

You can configure Lenovo Storage V7000 for event notification by SNMP, syslog or email. To configure notification, you must ensure that the SNMP agent, syslog IP addresses or SMTP email server IP addresses can be accessed from all Lenovo Storage V7000management addresses.

Lenovo Storage V7000 does not use name servers to locate other devices. You must supply the numeric IP address of the device. To locate a device, the device must have a fixed IP address.

The nodes in a Lenovo Storage V7000system can receive native IPv4 or IPv6 packets. The nodes cannot operate as an endpoint of a tunnel where an IPv4 packet contains an IPv6 payload or where an IPv6 packet contains an IPv4 payload.

To summarize then, with regards to IPv6 protocols supported:
  • IPv6 for iSCSI data traffic (to Control Enclosure) is supported
  • IPv6 for Management is not supported.
