Notes​

  • Routers A and B are the two MikroTiks described on the Calypso network page; router C is an FS S3600-48T4S switch attached to the CCR2004 on port sfp+12.
  • pagode0 / pagode1 are the Pagode AI workstation pair, momentarily removed from the rack.
  • epyc0 / epyc1 (dual-EPYC Gigabyte R282-Z92) are the servers earmarked for the future Proxmox infrastructure — see Future work. epyc0 runs Proxmox already (VM-type MAC addresses answer on 192.168.91.247 / .248).
  • rumba is the Rumba GPU server; calypsomaster is the Calypso cluster master.
  • The seven spare Dell R630 (U26–33) are racked and reachable over iDRAC but not active as Calypso nodes.
