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.

If you require some other type of dataplane connections for your OpenFlow experiment, please contact ​geni-users@googlegroups.com.
