eNAS I/O Modules are dedicated to eNAS and cannot be shared for other connectivity. When planning host to eNAS connectivity for performance and availability, connect at least two physical ports from each Data Mover to the network. Similarly, connect at least two ports from each host to the network. In this way, eNAS can continue to service the host I/O, in case of a component failure.
For best performance and availability, use multiple file systems and spread them across all the Data Movers serviced by different Ethernet interfaces. Each NAS share created on the Data Mover is accessible from all ports on the Data Mover, so it is essential that the host has connectivity to all the ports of the Data Mover. With SMB 3.0, the host can take advantage of load balancing and fault tolerance if multiple Ethernet ports are available on the host. For non-SMB 3.0 environments, create virtual network devices that are available to selected Data Movers, selecting a type of Ethernet channel, link aggregation, or Fail Safe Network (FSN). Do this before you create an interface.
VNX documentation provides information about configuring virtual Ethernet devices.
The cables that need to be connected are:
Note: The entire network infrastructure must also support jumbo frames.
