When inspecting your server's hardware (using lscpu on Linux or Task Manager on Windows), you might notice that the processor is identified as an older model, such as Intel Sandy Bridge.
Do not worry: This is not the actual physical hardware running your server.
The Technical Explanation: CPU Masking
Tilaa uses a diverse fleet of physical servers, ranging from previous generations to the latest Enterprise CPUs. To ensure your VPS remains stable, we use a technique called CPU Masking in our virtualization layer.
Why do we do this?
We mask the specific details of the physical CPU to a common baseline (Sandy Bridge) to guarantee Live Migration compatibility.
- Stability: If we passed through the exact physical CPU model (e.g., a modern Xeon Gold), and we needed to move your VPS to a host with a slightly different CPU generation (during maintenance or load balancing), your server would crash immediately due to mismatched CPU instruction sets.
- Mobility: By presenting a standardized "virtual CPU" model that is understood by all servers in our fleet, we can seamlessly move your VPS between hosts without downtime or errors.
Does this affect performance?
No. You still benefit from the raw clock speed and processing power of the underlying modern hardware.
The "Sandy Bridge" label is merely a compatibility flag for the Operating System to ensure it doesn't try to use CPU instructions that might not be available on every single host in our cluster.
