Performance optimization engagement for a 7-host Proxmox R&D cluster.
Captures the accumulated work across host tuning, network analysis,
fleet assessment, and kubernetes architecture planning.

Contents:
- Host-side tunings (scripts/): CPU governor, swappiness, BBR, NFS
  nconnect, tuned profiles -- complete on 5 of 7 hosts
- Validation + benchmarking scripts: iperf matrix, bond/NFS fixes
- Collected host data (returned-logs/): check.sh output from all 7
  hosts + iperf results, including newly-validated pfv-tsys9
- AGENTS.md: operating context for AI agents
- PROJECT.md: board-ready fleet assessment with VM placement and
  storage redundancy analysis (40 VMs across 7 hosts)
- K8S.md: kubernetes architecture deep-dive covering cnode/wnode
  distribution, StorageClass design, and ETL/HPC workload planning

!# pfv-r3-tor-stor
!#
!# Rack 3 storage TOR (VLAN1000 storage + VLAN1).
!# Carries the 4-port LACP to pfv-core-sw01 (Rack 5).
!# Most important switch for cross-rack storage throughput.
!#
!# Paste from enable mode after `terminal datadump` (DNOS 4/6) or
!# `terminal length 0` (DNOS 9 / OS9). Capture to returned-logs/pfv-r3-tor-stor.log
