Logical interconnects
The appliance enables you to define multiple enclosure interconnect modules as a single
administrative entity called a
logical interconnect , which provides universal access to data center
Ethernet networks from all servers connected to any member interconnect. A logical interconnect
is the set of physical interconnects and their links, including the following:
•
Uplinks to data center networks as mapped by their uplink sets
•
Downlinks to the servers
•
Stacking links (connections to each other)
Logical interconnect groups
A logical interconnect group is a collection of logical interconnects that have the same configuration
for features such as the following:
•
Stacking domain
•
Firmware
•
Uplink sets
•
Uplink port redundancy and fault tolerance
When you add an enclosure and associate it with an enclosure group, the enclosure is automatically
configured according to the logical interconnect group associated with the enclosure group. This
feature enables you to provision hundreds of enclosures consistently and efficiently.
After you create a logical interconnect, it continues to be associated with the logical interconnect
group and reports if its configuration differs from the group.
Network sets
You can define a collection of Ethernet data center networks to be identified by a single name,
called a
network set . You can specify a network set instead of an individual network when you
define a connection from a server to the data center networks. By using network sets, you can
make changes to networks that are members of a network set without having to make changes to
each server profile that uses that network set.
Network sets are useful in virtual machine environments where each server profile connection must
access multiple networks. For example, you can configure a hypervisor with a vSwitch to access
multiple network VLAN IDs by creating a network set as a trunk that includes the networks that
have these VLAN IDs.
