Problem Statement

With 10GB connections becoming the norm, ESXi hosts will generally have less physical connections than in the past where 1Gb was generally used, but more bandwidth per connection (and in total) than a host with 1GB NICs.

In this case, the hosts have only to 2 x 10GB NICs and the design needs to cater for all traffic (including IP storage) for the ESXi hosts.

The design needs to ensure all types of traffic have sufficient burst and sustained bandwidth for all traffic types without significantly negatively impacting other types of traffic.

How can this be achieved?

Assumptions

1. No additional Network cards (1gb or 10gb) can be supported
2. vSphere 5.1
3. Multi-NIC vMotion is desired

Constraints

1. Two (2) x 10GB NICs

Motivation

1. Ensure IP Storage (NFS) performance is optimal
2.Ensure vMotion activities (including a host entering maintenance mode) can be performed in a timely…
