System Hardware Requirements¶
StarlingX has been tested to work with specific hardware configurations. For more information, see Self Validated and Certified Hosts.
If the minimum hardware requirements are not met, system performance cannot be guaranteed.
All-in-One Simplex¶
The recommended minimum hardware requirements for bare metal servers for various host types are:
Minimum Requirements |
All-in-one Controller Node |
---|---|
Number of servers |
1 |
Minimum processor class |
Dual-CPU Intel® Xeon® E5 26xx family (SandyBridge) 8 cores/socket or Single-CPU Intel® Xeon® D-15xx family, 8 cores (low-power/low-cost option) Note
|
Minimum memory |
64 GB
|
Primary disk |
500 GB SSD or NVMe (see Configure NVMe Drive as Primary Disk) |
Additional disks |
|
Minimum network ports |
|

1 (Only required if used for initial installation of controller-0). |
Power profile |
C-states (up to C6) may be configured for some use cases where application workloads can tolerate additional scheduling/timer latency. Note C-states may be enabled depending on application requirements. |
Boot order |
HD, PXE, USB |
BIOS mode |
BIOS or UEFI Note UEFI Secure Boot and UEFI PXE boot over IPv6 are not supported. On systems with an IPv6 management network, you can use a separate IPv4 network for PXE boot. For more information, see PXE Boot Controller-0. |
