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
18.4 About network sets
A network set is a collection of tagged Ethernet networks that form a named group to simplify
server profile creation. Network sets are useful in virtual environments where each server profile
connection needs to access multiple networks. Network sets define how packets will be delivered
to the server when a server Ethernet connection is associated with the network set. Network sets
also enable you to define a VLAN trunk and associate it with a server connection.
Instead of assigning a single network to a connection in a server profile, you can assign a network
set to that connection.
•
Using network sets, you can quickly deploy changes to the network environment to multiple
servers. For example, you have 16 servers connected to a network set. To add a new network
to all 16 servers, you only need to add it to the network set instead of each server individually.
•
You can create a network set for your production networks and one for your development
networks.
•
You can configure a hypervisor with a vSwitch to access multiple VLANs by creating a network
set as a trunk that includes these networks.
Network set details
•
Network sets are supported for use in server profiles.
•
All networks in a network set must be Ethernet networks and must have unique external VLAN
IDs. Untagged and tunnel networks are single networks and do not use network sets.
•
All networks in a network set must be configured in the same appliance.
•
A network can be a member of multiple network sets.
•
When a network is deleted, it is automatically deleted from all network sets to which it
belonged.
•
A network set can be empty (contain no networks) or can contain one or more of the networks
configured in the appliance. Empty network sets enable you to create network sets in the
configuration before you create the member networks, or to remove all of the member networks
before you add their replacements. However, if a server profile adds a connection to an empty
network set, the server cannot connect to any data center networks using that connection.
•
When you create or modify a network set, you can designate a network for untagged packets.
If you do not designate a network an untagged network, untagged packets are rejected on
the profile connection associated with this network set.
•
Server traffic must be tagged with the VLAN ID of one of the Ethernet networks in the network
set. Untagged server traffic is either sent to the untagged network (if an untagged network is
defined) or is rejected (if no untagged network is defined).
