The following table lists the models of the Lenovo Storage V3700 V2 expansion enclosures.

Each Lenovo Storage V3700 V2 expansion enclosure ships with two expansion canisters. Each expansion canister provides 12 Gb SAS connectivity to the internal drives and two external 12 Gb SAS x4 ports (Mini-SAS HD SFF-8644 connectors labelled Port 1 and Port 2) that are used for connections to the Lenovo Storage V3700 V2 or V3700 V2 XP node canisters and for daisy chaining the expansion enclosures between each other. The expansion port (Port 1) on the left and right node canisters is connected to the Port 1 on the left and right expansion canisters, respectively. The Port 2 on the left and right expansion canisters is connected to the Port 1 on the left and right expansion canisters in the adjacent enclosure, respectively, and so on.
