I am implementing 1000v on ESXi servers connected via 2242UPs to 5596UPs via CNAs.
The port configuration on the 5/2Ks is using the Cisco default which assigns 50% of the bandwidth of the 10Gb link to the server to FCoE (should it be needed)
The question now arises when configuring QoS on the 1K uplinks when I configure a percentage for a traffic class what is it a percentage of ?
Is it a percentage of 10Gb or of 5Gb ? Has DCBX pushed the 50% for FCoE down the servers CNAs and does the 1K know this or does it think it still has a 10Gb interface all to itself ? I am trying to guarantee vmotion 1Gb and don't know whether that means I should assign a minimum of 10% or 20% in the 1K uplink QOS.
(A tad confused)
