+Networking
+----------
+
+Test-bed network
+
+* 24 or 48 Port TOR Switch
+* NICS - 1GE, 10GE - per server can be on-board or PCI-e
+* Connectivity for each data/control network is through a separate NIC.
+  *This simplifies Switch Management howeverrequires more NICs on the server and also more switch ports
+* Lights-out network can share with Admin/Management
+
+Network Interfaces
+
+* Option I: 4x1G Control, 2x40G Data, 48 Port Switch
+
+  * 1 x 1G for ILMI (Lights out Management )
+  * 1 x 1G for Admin/PXE boot
+  * 1 x 1G for control Plane connectivity
+  * 1 x 1G for storage
+  * 2 x 40G (or 10G) for data network (redundancy, NIC bonding, High bandwidth testing)
+
+* Option II: 1x1G Control, 2x 40G (or 10G) Data, 24 Port Switch
+
+  * Connectivity to networks is through VLANs on the Control NIC.
+    * Data NIC used for VNF traffic and storage traffic segmented through VLANs
+
+* Option III: 2x1G Control, 2x10G Data, 2x40G Storage, 24 Port Switch
+
+  * Data NIC used for VNF traffic
+    * Storage NIC used for control plane and Storage segmented through VLANs (separate host traffic from VNF)
+  * 1 x 1G for IPMI
+  * 1 x 1G for Admin/PXE boot
+  * 2 x 10G for control plane connectivity/Storage
+  * 2 x 40G (or 10G) for data network
+
+Documented configuration to include:
+- Subnet, VLANs (may be constrained by existing lab setups or rules)
+- IPs
+- Types of NW - lights-out, public, private, admin, storage
+- May be special NW requirements for performance related projects
+- Default gateways
