VMWare VMKernal ports and over subscription with Equallogic SANs

Previously it was possible to assign multiple VMkernel ports to physical nics. This was called over subscribing and was done to attempt to obtain more bandwidth for the environment especially when the ESX server had 10Gb nics and the SAN was running multiple 1Gb ports. Dell and VMware have changed the support for this practice and now only recommend using a 1:1 VMkernel binding process as described in this updated technical report.
