I would expand this document to include options over OTV. It may only be possible in 6.2 coming out soon that will allow for selective unicast flood. Otherwise, good info to share with the masses.
ITD (Intelligent Traffic Director) is a hardware based multi-Tbps Layer 4 load-balancing, traffic steering, redirection, and clustering solution on Nexus 5K/6K/7K series of switches. It supports IP-stickiness, resiliency, NAT (EFT), VIP, health monitoring, sophisticated failure handling policies, N+M redundancy, IPv4, IPv6, VRF, weighted load-balancing, bi-directional flow-coherency, and IPSLA probes including DNS. There is no service module or external appliance needed. ITD is much superior than legacy solutions like PBR, WCCP, ECMP, etc.
