InstaGENI Aggregate

University of Utah Downtown Data Center InstaGENI

This InstaGENI aggregate supports the GENI Aggregate Provider Agreement (08/13/2013).

InstaGENI Aggregate Overview

Aggregate Manager URL	​https://utahddc.geniracks.net:12369/protogeni/xmlrpc/am
Aggregate Manager URN	urn:publicid:IDN+utahddc.geniracks.net+authority+cm
Aggregate Manager Common Name	utahddc-ig
Aggregate Resources	This InstaGENI aggregate includes 33 hosts (12 XEN VM Servers and 21 dedicated PCs) that can load experimenter specified OS images. This aggregate also supports OpenFlow topologies. Rack servers are HP ProLiant DL380p Gen8.
Typical Experiments	InstaGENI provides a controllable, predictable, and repeatable network environment. Experimenters can get virtual machines or dedicated PCs on which they have full "root" access, run available operating systems of their choice, and connect nodes in an arbitrary topology that can support OpenFlow.

OpenFlow over GENI Network Stitching

This rack supports running hardware OpenFlow experiments over stitched GENI network connections. Please be advised that the following restrictions apply:

• Network stitching on the InstaGENI rack allocates and enforces link bandwidth, which cannot be modified by OpenFlow.
• VLANs allocated to stitched connections on the rack cannot be modified, because InstaGENI rack switches operate in hybrid mode, preventing VLAN tag rewriting.

The following is the layout of OpenFlow switch connections for the InstaGENI Aggregate. Shown are the OpenFlow Switches:

• InstaGENI Switch procurve2: Model: HP J8697A Switch E5406zl

Port List

InstaGENI Rack OF Switch UEN OpenFlow connection is via port name="B22" num="46" on the procurve2 switch.

All host eth1, eth2 and eth3 interfaces are connected to the OpenFlow switch for experimental use. Full list of port names and port numbers:
