HP Virtual Connect for c-Class BladeSystem Version 3.00 Setup and Installation Guide for HP Integrity BL8x0c i2 Series Server Blades, Fifth Edition

Installation 41
The VC manager in the primary enclosure accesses all remote modules and OAs over the management
network. The OAs for each enclosure to be managed as part of a VC domain must be on the same
management subnet along with all of the VC-Enet and VC-FC modules that are in each of the enclosures.
All enclosure OAs and VC modules within the same VC domain must be on the same lightly loaded
subnet. The OA IP addresses used must be configured to be static. The VC-Enet modules use stacking
cables between enclosures to route network traffic from any server port to any uplink port within the VC
domain. Bay 1 and bay 2 of the primary enclosure must have Fibre uplinks.
IMPORTANT: In multi-enclosure configurations, the HP 1/10 Gb VC-Enet Module is not
supported in bay 1 or bay 2 of the primary enclosure. The HP 1/10 Gb VC-Enet Module is
supported in bays 3 -8 of the primary enclosure, and in all bays of a remote enclosure.
The VC-FC modules do not support stacking. Connecting multiple enclosures requires identical VC-FC
module bay configuration in each enclosure. For additional information, see "FC bay configuration using
multiple enclosures (on page 43)."
The following figure shows an example of stacking multiple enclosures.
To add additional enclosures to a domain, see the HP Virtual Connect for c-Class BladeSystem User
Guide.
