|---|---|---|
| Architecture | x86_64 (64-bit) | x86_64 (64-bit) |
| CPU | 2 cores | 4+ cores |
| RAM | 4 GB | 8 GB or more |
| Storage | 50 GB | 100 GB SSD |
| Network | 100 Mbps | 1 Gbps |
Partitioning Scheme
The following partitioning scheme is recommended:
| Partition | Space |
|---|---|
| /boot | 1024 MB |
| /boot/efi | 600 MB (UEFI systems only) |
| /tmp | 2048 MB |
| / | Minimum 50 GB |
Virtualization
DNS Manager is designed to be used in virtualized environments. DNS Manager was tested with the following hypervisors:
- VMware vSphere / ESXi
- KVM / QEMU
- OpenStack
In case of virtualization, we recommend:
- Do not over-provision RAM and CPU
- Use paravirtualized drivers for best performance
