System requirements for the Proxmox cluster

So, we have talked so much about the Proxmox cluster. To use this mode, we have to first prepare at least two machines that are installed with Proxmox VE. If we want to have a basic testing platform, what would be the minimum requirement for our machines?

The minimum system requirements as listed on the Proxmox website are as follows:

• CPU: 64-bit (Intel EMT64 or AMD64)
• Intel VT/AMD-V capable CPU/Mainboard (for KVM)
• Minimum 1 GB RAM
• Hard drive
• One NIC

However, I would recommend that you have at least 2 GB memory if you want to test online migration on the Windows platform.

For a production environment, the following hardware is suggested by Proxmox:

• CPU: The CPU must support 64-bit (Intel EMT64 or AMD64), multicore CPU is recommended, and Intel VT/AMD-V capable CPU/mainboard is required (for KVM support)
• 8 GB RAM is good; the more the better
• Hardware RAID with battery backup unit (BBU) or flash-based protection (software RAID is not officially supported by...
