+Sites in GENI have used !OpenFlow switches from HP, NEC, and Pronto. Here's a table of what's currently connected to the mesoscale:

+= !FlowVisor =
+
+Sites typically use !FlowVisor to slice their !OpenFlow switches between multiple experiments. Different sites are running their !FlowVisor on a variety of hardware (including in VMs); Stanford currently recommends that a !FlowVisor server should have at least 3 GB of RAM and at least two CPUs. Fast disks also help, as !FlowVisor (as of 0.8.1) can be I/O intensive. These requirements may increase for larger scale deployments.
+
+It's also advantageous to have a robust control network interface to !FlowVisor. Stanford currently recommends two gigabit interfaces, one to communicate with switches ("upstream") and one to communicate with controllers ("downstream"), if your network design permits. If your upstream and downstream traffic need to share an interface, it might be prudent to have a 10 GB NIC.
