UCS 5108+UCS B200 M4 + Cisco UCS VIC 1340 modular LOM+vNICs & vHBA

[reply2vinay]

Hello all,

I need a guidance to do a NIC partitioning part at Blade level, as per below configuration.

• Enclosure : 1xUCS 5108
• Blade : UCS B200 M4 + Cisco UCS VIC 1340 modular LOM  ( No port extender)
• Chassis to FI  Connectivity - FEX-A & FEX-B 2+2= 4 connections ( Not using remaining 2+2 ports from FEX-A & FEX-B)
• FI - 2x6248UP

Assumption - As per above physical connectivity, I get 40G FCOE bandwidth per chassis and blade will get 40/8=5G FCOE bandwidth coorect me If I'm wrong.

Requirement :

1. vNICs - 6
2. vHBA - 2

Please guide me step by step how can I meet my requirement by starting from Blade server NIC partitioning settings.

Thank you in Advance!!

Hi

See eg. https://ucsguru.com/2012/05/18/understanding-ucs-vif-paths/

With two IOM-to-FI links, servers in slots 1,3,5,7 use link number 1, while slots 2, 4, 6, 8 link number 2.

Best practise is to configure port-channel between IOM and FI. This has the advantage, that if one link fails, there is no disruption, only a loss of 50% of the bandwidth; in the non pc case, half of the slots per fabric are down.

I would start doing a configuration without any QoS and then do a baselining. You could then later add QoS, if necessary:

Thank you for your inputs.

Do we have any document for the best practices which can be used for UCS manager configuration ? If yes please share it.
