It also depends if you are using Multipath HA or single path if you're using shelves. &nbsp;If you are using Multipath HA then each controller is connected to every shelf, otherwise the shelved depend on the controller that goes down

robocat is right on. paulsolov's comment has nothing to do with your question. &nbsp;I would also suggest single-mode vifs to multiple switches, and spanning-tree portfast in order to ensure network redundancy and quick recovery.

What is network behavior like when dual NetApp controllers are connected via a single Ethernet link each to two upstream switches? Is there a need for any loop prevention under this scenario? What are some design guidelines for this topology?

Netapp Controller Connectivity to Two Upstream Switches

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
