===== Summary =====
Red Hat purchased 5 servers and a 100Gb switch to be used for RGW Scale testing in Q1 2021. I just decided to put them in Sepia due to physical space constraints in Octo.

===== PXE/Reimaging =====
These PXE using Legacy/BIOS mode and can be provisioned via Cobbler normally.
===== Network Config =====
==== qfx-rgw ====
These nodes have a regular 1Gb uplink but then 2x 25Gb connections per server to a QFX5120-32C for backend storage traffic. This switch is managed by Ceph Infra and not uplinked.
I purchased qty 5 100Gb -> 4x 25Gb breakout cables with this. See https://docs.google.com/spreadsheets/d/1_ETaz5ollV_66ODFGXiVWEibecdBZIvHg9X1zN1pF88/edit#gid=0
I just created a ''/24'' vlan on the switch giving each server it's own Aggregated Ethernet interface.

The switch is named ''qfx-rgw.ipmi.sepia.ceph.com'' and can be accessed via SSH. Here's the current switch config that seems to be working.

==== Server bond config ====
Here's what I ran to set up the bonds initially. The bonding type may change.
nmcli connection add type bond con-name bond0 ifname bond0 bond.options "mode=802.3ad"
nmcli connection add type ethernet slave-type bond con-name bond0-port1 ifname eno1np0 master bond0
nmcli connection add type ethernet slave-type bond con-name bond0-port2 ifname eno2np1 master bond0
### Change the IP in this line!
nmcli connection modify bond0 ipv4.addresses '172.20.23.X/24'
nmcli connection modify bond0 ipv4.gateway '172.20.23.254'
nmcli connection modify bond0 ipv4.method manual
nmcli connection modify bond0 connection.autoconnect-slaves 1
nmcli connection up bond0
