See “Related information” (page 182) for documents that can have more information on “stacking
links.”
Figure 28 (page 54) illustrates a valid configuration of Ethernet and Fibre Channel Virtual Connect
modules in a VC Domain with multiple enclosures. The black lines linking the Ethernet modules
illustrate the stacking links.
VCEM supports VC Domain Groups containing VC Domains with multiple enclosures, and enables
the VC Domains to contain different numbers of enclosures, as long as each VC Domain contains
the minimum number of enclosures. The Ethernet uplinks define the minimum number of enclosures.
The enclosure with a defined Ethernet uplink port defines the minimum number of enclosures.
In this example, the minimum number of enclosures is two. The second enclosure is the last enclosure
that contains Ethernet uplink ports.
Figure 28 Valid configuration of Ethernet and Fibre Channel VC modules
As in earlier versions of VCEM, all VC Domains within a VC Domain Group must have the same
hardware configuration. VCEM enables each enclosure within a VC Domain with multiple enclosures
to have a different Virtual Connect Ethernet module configuration as described in the Virtual Connect
documentation, but it requires the same Virtual Connect Ethernet Module configuration across the
VC Domain Group members. The base enclosure of every VC Domain within one VC Domain
Group must have the same VC Ethernet module configuration. Similarly, every VC Domain that
has more than one enclosure must have the same VC Ethernet module configuration in all the
enclosures.
Figure 29 (page 55) illustrates a VC Domain Group containing VC Domains with different numbers
of enclosures.
