PXE/Reimaging
These PXE using Legacy/BIOS mode and can be provisioned via Cobbler normally.
Network Config
These nodes are connected to the officinalis QFX5200 (s/n WH0218170419 [formerly WH3619030401]) uplinked and managed by Red Hat IT. For an example of how to report an outage, see https://redhat.service-now.com/surl.do?n=INC1201508.
The 100Gb connection is the only uplink for now. The top-of-rack switch in that rack probably has capacity if we need a 1Gb uplink and reserve the 100Gb NIC for backend traffic.
