  • Mgmt/Cluster: 1x10GE

  • Data: 1 or more x 10GE

BIOS settings

  • Hyper-Threading technology enabled

  • Virtualization technology enabled

  • VT for directed I/O enabled

  • CPU power and performance policy set to performance

  • CPU C state control disabled

  • Plug & play BMC detection disabled

Prepare bare metal servers

Prior to starting the StarlingX installation, the bare metal servers must be in the following condition:

  • Physically installed

  • Cabled for power

  • All disks wiped

    • Ensures that servers will boot from either the network or USB storage (if present)

  • Powered off

  • Cabled for networking

    • Far-end switch ports should be properly configured to realize the networking shown in the following diagram.
