 The OpenGENI rack is implemented on Dell hardware, here is the [wiki:GENIRacksHome/OpenGENIRacks/DellPartsList parts list].
 
+=== Q. How can I tell if experiments are running in my OpenGENI rack? ===
+On the control node you can check the list of experiments that are currently active by issuing an !OpenStack command 
+as follows: 
+{{{
+$ source /etc/novarc 
+$ $ keystone tenant-list|egrep slice
+| 8f38b505cbef4c4a82463f250d3f9ad6 |    ch.geni.net:ln-test+slice+OG-EXP-1    |   True  |
+| cc16776ac7b44341a2430546c2907684 | ch.geni.net:ln-test+slice+gr-clem-ig-gpo |   True  |
+| 559624c7d7b043aeb3a3128bb393e9d3 |    ch.geni.net:ln-test+slice+lnexp23     |   True  |
+}}}
+The list returned shows that there are 3 experiments that have active resource allocations.
+
+=== Q. Are there OpenGENI logs? ===
+The OpenGENI rack runs GENI Rack Aggregate Manager (GRAM) software to manage rack compute and network resources. There are 4 gram processes to provide these functions and
+their logs are:
+  - /var/log/upstart/gram-am.log - The aggregate manager logs which AM API requests and the quantum commands used to allocate the requested resources. 
+  - /var/log/upstart/gram-ctrl.log - The !OpenFlow Controller running on the OpenGENI rack which will capture request for OF resources. 
+  - /var/log/upstart/gram-opsmon.log - Monitoring log is created by the gram-mon daemon, file captures relevant information from the GRAM snapshots which are logged in this file easier readability.
+  - /var/log/upstart/gram-vmoc.log - VLAN-based Multiplexing !OpenFlow Controller (VMOC) is a switch to experimenter provided controller, that multiples based on VLAN tag and switch DPID/port. A default Layer2 Learing controller is used for slices that do not specify a controller.
