Pre-Purchase
Connection between OpenFlow switches should ideally appear like layer 1 connections to the experimenters. This can be accomplished in various ways including using dedicated fiber, existing pseudo-wire technologies, OF switches to pass traffic, or applying special configurations to traditional layer 2 VLANs such as disabling mac learning and STP.
- Does your site require any additional hardware or support in preparing your network environment for hosting a GENI rack?
- Do you need an additional transceiver to connect the 10Gb uplink connection from the rack to your network?
Post-Purchase
Important: If the following information is not or cannot be provided prior to the rack being sent to your site, you will receive the hardware with only a bare OS installed on all servers and the switch un-configured. In order to have your rack delivered as a ready to be deployed product, you MUST provide the following:
OS Installation
Hostname:
- What is a unique name for your location? (Example: USC-Spartburg; USC-Columbia)
- How do we check conflicts??
- Use this information to generate a unique identifier for GENI.
- Ie: <company>-<location>-<function>-<number>
- Clemson-main-ctrl-1, Clemson-main-comp-1,etc
- Generated by us based on customer. Information given to customer after they purchase the unit.
- Tracked by integrator so if 2nd order is placed we know which number to start off on.
GRAM software
Range and subnet of public IP addresses for virtual machines:
- Define a range of contiguous IP addresses to be assigned to the Virtual Machines.
o Start_ip to end_ip must be a contiguous block of ip addresses not in use. There must be at least one, e.g.. 130.127.39.130 - 130.127.39.131. o xxx.xxx.xx.xx1-xxx.xxx.xx.xx2
VLAN information for external plane:
- Provide the external plane VLAN number for your site.
o Needed for switch configuration
External network configuration on control nodes and compute nodes
Assign the following for the control node attached to the system. (DHCP is not recommended as a change in IP address can disrupt the software utilized by GENI)
- Static IP address:_
- Subnet: _
- Gateway: _
- DNS Server:
Will the following ports be allowed through your campus/network firewall, to the entire rack subnet:
- 22 - ssh
- 25 - smtp (outbound connections only, from control node)
- 80 - http (must also allow outbound connections from control node)
- 443 - https (must also allow outbound connections from control node)
- 843 - Flash Policy Server
- 5001 - GRAM
- 5002 - GRAM
- 30000-65535 - Ports used by software.
- GRE - Not a port, but an IP protocol, required for constructing tunnels between racks.
- ICMP - ping
iDRAC network configuration Static IP address Subnet Gateway DNS server
- If we use control plane, IP address is assigned internally within the rack. (After talking with Dell I don’t think this is an option. iDRAC needs its own interface)
Force10 switch network configuration
Assign the following:
- Static IP address
- Subnet
- Gateway
PT7048 switch network configuration
Assign the following:
- Static IP address
- Subnet
- Gateway
