Hardware allocation

  • CPUs: 32 CPUs,
  • 256GB RAM

  • Disk: 4 X 174 GB + 4 X 600 GB Disk

  • CPU unit resource ratio: 1 Unit = {1 Core; 2 GB RAM; 36 GB Disk}

  • With 256 GB RAM, unit is 1;8;36
  • Assumption: 1 Unit sufficient for container, 2 units required for VM
  • Assume largest VM requirement: 16 GB RAM = 8 units, with 8 CPUs and 288 GB disk.
