Hardware Requirements

This section describes the hardware requirements and server preparation for a StarlingX R6.0 bare metal Standard with Rook Storage deployment configuration.

Minimum hardware requirements

The recommended minimum hardware requirements for bare metal servers for various host types are:

Minimum Requirement	Controller Node	Worker Node for rook storage	Worker Node for application
Number of servers	2	2-9	2-100
Minimum processor class	Dual-CPU Intel® Xeon® E5 26xx family (SandyBridge) 8 cores/socket
Minimum memory	64 GB	64 GB	32 GB
Primary disk	500 GB SSD or NVMe (see Configure NVMe Drive as Primary Disk)	120 GB (min. 10k RPM)	120 GB (min. 10k RPM)
Additional disks	None	1 or more 500 GB (min. 10K RPM) for Ceph OSD Recommended, but not required: 1 or more SSDs or NVMe drives for Ceph journals (min. 1024 MiB per OSD journal)	For OpenStack, recommend 1 or more 500 GB (min. 10K RPM) for VM ephemeral storage
Minimum network ports	Mgmt/Cluster: 1x10GE OAM: 1x1GE	Mgmt/Cluster: 1x10GE	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.
