Networking
----------
**Network Hardware**
* 24 or 48 Port TOR Switch
* NICs - Combination of 1GE and 10GE based on network topology options (per server can be on-board or use PCI-e)
* Connectivity for each data/control network is through a separate NIC. This simplifies Switch Management however requires more NICs on the server and also more switch ports
* BMC (Baseboard Management Controller) for lights-out mangement network using IPMI (Intelligent Platform Management Interface)
**Network Options**
* Option I: 4x1G Control, 2x10G Data, 48 Port Switch
* 1 x 1G for lights-out Management
* 1 x 1G for Admin/PXE boot
* 1 x 1G for control-plane connectivity
* 1 x 1G for storage
* 2 x 10G for data network (redundancy, NIC bonding, High bandwidth testing)
* Option II: 1x1G Control, 2x 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, 2x10G 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 lights-out mangement
* 1 x 1G for Admin/PXE boot
* 2 x 10G for control-plane connectivity/storage
* 2 x 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
