Hello @NineWonders ,
Welcome to the forum!
You can run multiple nodes, just use different external ports.
Please note: each new node must be vetted, the unvetted node can receive only 5% of customers’ uploads until got vetted. To be vetted on one satellite the node should pass 100 audits from it. For the one node in the /24 subnet of public IPs it should take at least a month.
We filter out nodes behind the same /24 subnet of public IPs for uploads, so all such nodes will act as a one big node - we want to be decentralized as much as possible.
If you would start several new nodes in the same /24 subnet of public IPs the vetting process could be in the same amount of times longer as a number of such nodes.
Thus it’s better to start the next node only when the previous one almost full or at least vetted.
So from the technical point of view 3 nodes x10TB is equivalent to one node with 30TB with one exception - the vetting could be longer if you start all three at once.
But there is another point - three almost empty nodes will consume more power, while the amount of data will be the same. So, again - it’s better to start a next one only when the previous one almost full. Then the power consuming will grow with data growing.
Please also take a look at Realistic earnings estimator to have an idea how long it may take to fill up all that free space and how much you may earn.
