The new Cisco Validated Design document is out:
http://www.cisco.com/c/dam/en/us/td/docs/unified_computing/ucs/UCS_CVDs/flexpod_saphana_n9k.pdf
It describes a wholistic ACI-ready datacenter design based on FlexPod for SAP applications, including HANA. It also gives an introduction to Cisco and NetApp hardware. Definitely one of the most comprehensive design guides for SAP solutions today!
