On our VDS, the CPU is dedicated to your VM. The only thing your VDS will share with other VMs is the disk I/O, though as these nodes have fewer VMs on them, there is plenty of that to go around. In contrast, our VPS has shared CPU cores. The only thing that is dedicated on all of them is the RAM, and storage amount (only amount not I/O). All other resources are shared between everyone.
What is the maximum HDD storage size that I can add to a VM?
The maximum that you can add to a VPS is 32 TB.
Can you offer custom resources on your VDS platform?
Sadly, we can't. The underlying nodes that are built for VDS are inherently designed in a way that can fit a certain amount of VMs, with very certain resources only.
Your VM will be limited to 5 Mbps, and you won't be charged any extra amount for this. If you'd like to avoid the speed limit, please reach out to us to upgrade your bandwidth allocation.
