Connections

Ensure that you are familiar with the specific connection types for the system.

Each system requires the following connections:

Each Lenovo Storage V series control enclosure requires two Ethernet cables to connect it to an Ethernet switch or hub. One cable connects to port 1 of the left node canister, and the other cable connects to port 1 of the right node canister. For 1 GbE ports on Lenovo Storage V3700 V2 and Lenovo Storage V3700 V2 XP systems, the minimum link speed is 100 Mbps. On a Lenovo Storage V5030 system, 10 GbE ports require a minimum link speed of 1 Gbps. Both Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) are supported.
Note: For increased redundancy, an optional second Ethernet connection is supported for each system node canister.
To ensure system failover operations, Ethernet port 1 on each node canister must be connected to the same set of subnets. If used, Ethernet port 2 on each node canister must also be connected to the same set of subnets. However, the subnets for Ethernet port 1 do not have to be the same as Ethernet port 2.

Short-wave SFP transceivers are preinstalled in the control enclosure Fibre Channel ports and any 10 Gbps Ethernet ports. You can order long-wave SFP transceivers to replace the short-wave transceivers in the Fibre Channel ports only. 10 Gbps Ethernet ports for FCoE and iSCSI do not use long-wave transceivers.
