Bastille is our Lenovo Nextscale chassis donated by jpo from his VT Surplus spoils.
It contains twelve like 'blades', with:
- 2x Intel(R) Xeon(R) E5-2680 v3 (48) @ 3.30 GHz, 12 cores 24 threads each
- 256 GiB DDR4
- a fully-featured remote management interface, with a webUI kvm
- two gigabit eth NICs, and one Intel X520 2x10G SFP+
- notably, no peripheral ports other than a multiplexed one that uses a proprietary adapter to VGA, Serial, 2x USB
These blades are appropriately named:
[ "backbiter" "damocles" "durendal" "eyelander" "excalibur" "gram" "gryffindor" "kusanagi" "narsil" "oathbringer" "riptide" "sting" ]
They are at the moment netbooted from Infrastructure:Vesuvius as NixOS k3s nodes.

| prospit | - | - | User:Enzoisotton took this out of the server room to test pxe booting, yell at him until it's back |
| gryffindor | 10.98.0.31 | 10.98.3.8 | |
| kusanagi | 10.98.0.32 | - | the SFP+ NIC appears broken. may work if re-seated. |
| narsil | 10.98.0.33 | 10.98.3.10 | |
| oathbringer | 10.98.0.34 | 10.98.3.11 | |
| riptide | 10.98.0.35 | 10.98.3.13 | |
| sting | 10.98.0.36 | 10.98.3.14 |
Each machine has a management interface on 10.98.2.0/24, with the same last octet as its backend IP -- i.e. riptide can be managed from 10.98.2.13.

Guide
Technical
Each listed blade has four connections: two 8p8c NICs attached to Infrastructure:Magma, one for the frontend network, and one for its management interface, then two SFP+ NICs bonded together and connected to Infrastructure:Pahoehoe via QSFP+ breakout cable. The 20G bonded interface is used for the cluster's backend interconnect.
The frontend networks, uses DHCP with Infrastructure:Shellshock, while the backend network is statically routed.
You can spy their config here [1]
Operational
All users with a VTLUUG SSO account (read: FreeIPA/acidburn) can SSH to Infrastructure:Vesuvius on the VTLUUG LAN.
From there, all users with sudo access can use `kubectl` to manage the cluster, or proxy/jump to other nodes through the backend fabric.
