having to replicate configuration changes across multiple servers. In addition, the logical and physical network resources can be configured for high availability, including:

Providing redundant physical links to the data center networks

Configuring stacking links between interconnects in an enclosure to provide redundant paths from servers to data center networks

Using logical resources, such as logical interconnects, that represent multiple physical resources to allow continued uninterrupted operation if a physical component fails

The Virtual Connect interconnect modules in enclosures support the following types of networks:

Fibre Channel for storage networks, including both Fabric attach (SAN) Fibre Channel connections and Direct attach (Flat SAN) Fibre Channel connections

Ethernet for data networks

15.4.1About Fibre Channel networksYou can use Fibre Channel networks to connect to storage devices.15.4.1.1Fibre Channel network types

The Virtual Connect interconnect modules in enclosures support two types of Fibre Channel connections to storage devices:

Fabric attach connections—The enclosure interconnects connect to data center SAN fabric switches.

Direct attach connections—Also called Flat SAN, in which the enclosure interconnects connect directly to a supported storage device, such as an HP 3PAR StoreServ Storage system.

You cannot change the type of a Fibre Channel network, but you can delete the network from the appliance, and then add the network as a different type.

A logical interconnect can use both Direct attach storage and Fabric attach storage at the same time.
