Virtual Connect modules 232
When configuring horizontal or primary slice stacking, observe the following:
• A brief network outage occurs when you change the domain stacking mode.
• The following connections must reside within their configured logical interconnect for proper
functionality. These connections must not span outside of their logical interconnect:
o Network uplink ports ("Define Ethernet Network screen" on page 120)
o Shared uplink sets ("Define Shared Uplink Set screen" on page 134)
o Monitored ports ("Ethernet Settings (Port Monitoring) screen" on page 93)
o sFlow ports ("sFlow Settings (General) screen" on page 111)
When configuring networks, uplink ports are filtered to ensure that all ports belong to the same logical
interconnect.
• If there are connections not configured as stacking links between modules, the ports are linked and
function as normal uplink ports.
• Server to server communications between logical interconnects requires a connection between the
logical interconnects.
• Multiple enclosure configurations are supported and requires the primary slices of the enclosures be
connected with stacking cables.
• Profile migrations are not supported in multi-enclosure domains.
• Double-dense mode is not supported.
• HP BladeSystem c3000 Enclosures are not supported.
• HP recommends enabling Smart Link (on page 87).
Observe the following information when Ethernet modules are horizontally-adjacent:
• HP VC Flex-10 Enet modules
Uplink ports X7 and X8 form internal stacking links between the modules when left unpopulated.
• HP VC FlexFabric 10Gb/24-Port modules
Uplink ports X7 and X8 form internal stacking links between the modules when left unpopulated.
• HP VC Flex-10/10D Modules
Ports X11, X12, X13, and X14 are dedicated internal stacking links.
• HP VC FlexFabric-20/40 F8 Modules
Ports X9 and X10 are dedicated internal stacking links.
Determine the status of the stacking link:
• Connection Status indicates whether all of the VC-Enet modules within the domain are interconnected
with stacking links and accessible. Lack of connection status to all VC-Enet modules results in a critical
alert.
o OK indicates that all modules are connected.
o Failed indicates that one or more modules are not connected properly. Check the cable
connections.
• Redundancy Status indicates whether all VC-Enet modules would remain fully interconnected if a
module or external cable was removed or had failed. Horizontally-adjacent modules are considered to
have OK redundancy status because of the reliability of their internal link.
o OK indicates that redundant/reliable connections exist.
