Network connectivity is provided to the VMs by a virtual NIC (vNIC). The vNIC is connected to the internal network providing communication to PowerMaxOS and other VM instances. The VM management external network connectivity is provided through a PowerMaxOS component called the network address translation (NAT) Gateway which is part of the Infrastructure Manager (IM) emulation. The NAT Gateway provides translation services between external and internal IP addresses and uses a separate network connection on each of the two Management Module Control Stations (MMCS). A PowerMax with eManagement and Secure Remote Services connectivity would require a total of four physical network connections and four IP addresses. More IP addresses would be required if Embedded NAS is also configured. Management of Cloud Mobility is strictly performed through the eManagement in Unisphere and does not require any management IP addresses.
