Setup and Install

HP Virtual Connect Manager 78
o
An Ethernet network that is assigned to a profile or an sFlow configuration
o An FCoE network that is associated with a shared uplink set
VCEM enforces consistent in-use definitions across all domains in each domain group. If a domain
is in maintenance mode and changes are made which would increase the number of in-use
networks beyond 1000 for any domain in the domain group, the complete maintenance operation
fails, and the domain stays in maintenance mode.
HP recommends limiting the total number of FCoE VLANs on any individual VC ENET module to 32.
• 8,192 Ethernet and FCoE VLANs can be defined per domain.
• 4,094 Ethernet and FCoE VLANs can be defined per shared uplink set.
Shared uplink sets support a maximum of 32 FCoE networks.
• 162 VLANs can be defined per physical server port.
For example, if you configure 150 VLAN mappings to FlexNIC-a, then only 12 VLANs can be
configured for the remaining FlexNICs (FlexNIC-b, FlexNIC-c, and FlexNIC-d).
o Duplicate VLANs cannot be configured on the same physical port.
o Do not map more than 162 VLANs to one physical server port. If you exceed the 162 VLAN limit,
the physical server port is disabled and the four server connections are marked as failed.
When the domain is configured with the Legacy VLAN Capacity mode, observe the following:
• The option to select Legacy VLAN Capacity mode is disabled when creating new domains with VC
firmware 3.70 or higher. Reverting from Expanded VLAN Capacity mode back to Legacy VLAN
Capacity mode is not allowed.
• To maintain compatibility for VC domains configured with Legacy VLAN Capacity mode and
upgrading firmware from VC 3.30 to VC3.70 or higher, the VCM CLI maintains the functionality of the
Legacy VLAN capacity setting. This allows the use of existing scripts that configure the VLAN capacity
mode.
Multiple Networks Link Speed Settings
When using mapped VLAN tags (multiple networks over a single link), these settings are used for the overall
link speed control. Select the checkbox next to each item to set the value.
These settings affect only newly created profiles.
Versions of VC prior to v4.01 used the "preferred speed" to control bandwidth allocation. When existing
profiles are upgraded to VC v4.01 or later, the "maximum speed" from the network is set automatically on
the connection. If no maximum speed was configured prior to the upgrade, then the maximum speed is 20
Gb for Ethernet connections. The 20Gb maximum speed is dependent on 20Gb NICs and the HP VC
FlexFabric-20/40 F8 Module being present in the domain. The pre-4.01 behavior can be retained by setting
"maximum speed" to the same value as "preferred speed". When the maximum speed and preferred speed
for a network are set to the same bandwidth, then the profile connection bandwidth does not exceed the
custom speed set on the connection.
IMPORTANT: Depending on the NIC firmware versions in use, you might need to upgrade the
NIC firmware for these speed enforcement settings to work correctly.
To change these settings:
1. Click the selection box, and then select a setting (100Mb to 20Gb):
