Harmony Node - Hardware requirements

Hey, what kind of hardware do you guys suggest to build a node? Would be great to get a spec sheat or build sheat from you.

Hi, Max,

Thanks for the question. We haven’t finalized on the spec of the validator nodes yet.
As a general guidance in our current estimate, we are looking at the AWS m5d.xlarge instance type as a reference of the node machine.



just to update, since our network had grown very fast, we need more storage than before. Nodes in shard0 require at least 300Gb disk storage, shard1/2/3 requires at least 350Gb disk storage right now. To avoid out of space issues, we recommended a 500Gb disk attached to the instance or use local disk storage.


Thanks for the update, @leo. :pray:

Hi Leo, the document said the size for the shard 0 on mainnet is ~16Tb. So is it enough to take only 300GB for shard 0 for syncing the nodes? What is the difference between these two sizes of storage? By the way, the requirements indicated in the document as follow are similar to the size you recommended, so is it usable to follow those requirements ? Thanks !

16TB is the archival node. It is not necessary to ask a regular validator. For a regular validator, it is about 900GB right now. So, please prepare at least 1TB and prepare to grow the disk…


My shard_0 is currently 1.1TB and pruning seems to be stuck at this point. As a result, I recommend at least 1.6TB until pruning is fully working.

Now that there’s a pruned DB, what would you recommend as a storage size? 500 Gb?
