Cannot add vNIC on Flex 10
I have connected the CX4 cable to a pair of Cisco switches and trunked multiple VLAN's over these links.
The VLANs are created and defined under a single Shared Uplink Set with 1 CX4 as active and the other as standby.
I wanted to be able to use 6 vnics for my BL490C server for VMWare.
When I add connections over 2 in my server profile the 3 and subsequent NICs are mapped to the pass-thru ethernet module I have connected to the MEZZ 2 card via slot 5 & 6
How do I make use of the other 6 vNICs as I want to remove the MEZZ 2 card from the scenario.

Re: Cannot add vNIC on Flex 10
When the profile is assigned you should get this mapping:
1 LOM1:a
2 LOM2:a
3 MZ2:1
4 MZ2:2
5 LOM1:b
6 LOM2:b
7 LOM1:c
8 LOM2:c

Re: Cannot add vNIC on Flex 10
However it doesn't seem to like having the same network on multiple vNICs?
I wanted to be able to say use 3 vNICs for vlans x,y & z and then put vlans a,b & c on the other vNICs for redundancy.

Re: Cannot add vNIC on Flex 10
put vLan_x on LOM1:a and vLan_a on LOM2:a,
then vLan_y on LOM1:b and vLan_b on LOM2:b,
and vLan_y on LOM1:c and vLan_c on LOM2:c.
Redundancy and failover it achieved by teaming the pairs a-x, b-y, c-z.
If it is a bandwidth issue, then this adjustable between FlexNic ports, upto an aggregate of 10Gb.

Re: Cannot add vNIC on Flex 10
The idea is to do 2 things but primarily #1
1. Allow for failure of a NIC Port
2. Allow for 3 NICs for aggregated bandwidth

Re: Cannot add vNIC on Flex 10
WHat do you think you will gain from aggregating 3 vNICs?
You are still limited to the 10GB port speed...
Since we are probably talking about embedded nic's here... you are more likely to lose something else before EVER losing a nic port. And if you lost a nic port... it is likely you will lose booth nic ports as there is something probably wrong with the embedded circuitry... requiring a system board replacement.
While dealing with blades, you are probably better off taking care of redundancy with an additional blade... especially in a virtual environment.

Re: Cannot add vNIC on Flex 10
2 or more FlexNICs(a, b, c, d) from the same Flex-10 port i.e. LOM1 can not be a member of the same Virtual Connect Network.
But, you can have duplicate networks across LOMs.
Valid (and provides redundancy):
LOM1:a -> vlan_1
LOM2:a -> vlan_1
LOM1:b -> vlan_2
LOM2:b -> vlan_2
LOM1:c -> vlan_3
LOM2:c -> vlan_3
LOM1:d -> vlan_4
LOM2:d -> vlan_4
Invalid (and doesn't provide redundancy):
LOM1:a -> vlan_1
LOM2:a -> vlan_2
LOM1:b -> vlan_3
LOM2:b -> vlan_4
LOM1:c -> vlan_1
LOM2:c -> vlan_2
LOM1:d -> vlan_3
LOM2:d -> vlan_4
