Hardware requirements

Who this is for: operators sizing a host before deploying a Lumia RPC node.

Every figure below is a working estimate, not a published spec. Confirm before you provision anything at scale.

RPC node

Resource	Minimum	Recommended	Notes
CPU	4 cores, x86_64	8+ cores	Single-thread performance matters more than core count for sync speed
RAM	32 GiB	64 GiB	Stated as a hard minimum for the execution client, not a soft recommendation
Disk	1 TB NVMe SSD	2×1 TB NVMe	Local NVMe only: no network-attached or spinning storage; current chain state is far smaller than 1 TB, but the figure covers growth
Network	1 Gbps, public IPv4 if serving external clients	1 Gbps+, meaningful monthly egress budget	Egress scales directly with RPC traffic served

This is the node type most operators actually want. See RPC node overview.

Before you provision

• Confirm free disk headroom before starting a snapshot bootstrap: running out of space mid-extract is a common cause of a corrupted data directory. See Node troubleshooting.
