Hardware requirements (2024)

The hardware requirements for storage providers are tied to the computational resources needed to seal a sector and generating regular Proof of Spacetime for every sealed sector.

The Filecoin network requires storage providers to run computationally expensive operations to generate sealed sectors. The cost of these operations depends on which network the storage provider is running; some testnets use a smaller sector size to increase the speed of sealing artificially. For reference, the requirements listed below correspond to 32GiB sectors, as used by mainnet and the calibration network (testnetwork).

General hardware requirements #

The Filecoin consensus relies on multiple stages, which are very difficult to execute on a single type of hardware. Therefore, it is strongly not recommended to try to run all parts of an SP from a single machine, as supporting such a setup economically is impossible. To complement the hardware recommendations for each task type or process, it is advisable to configure and delegate sealing phases to lotus-worker, particularly in setups where multiple sectors need to be sealed in parallel. This will help ensure that each specific operation requirement is met and that the lotus-miner process run smoothly.

CPU #

To run the just the lotus-miner process without any sealing tasks, it is recommended to have at least a CPU with 8 cores.

PC1 #

For the PreCommit1 task a CPU model with support for Intel SHA Extensions: AMD since Zen microarchitecture, or Intel since Ice Lake, is a must. Lack of SHA Extensions results in a very significant slow down.

PC2 #

For the PreCommit2 task a CPU with a lot of cores will speed up the process, unless the task is offloaded to a GPU, which is highly recommended to speed up the task.

C2 #

For the Commit2 task a CPU with a lot of cores will speed up the process, unless the task is offloaded to a GPU, which is highly recommended to speed up the task.

RAM #

128 GiB of RAM are recommended at the very least if the lotus-miner when the windowPoSt task is not outsourced to a windowPoSt worker. This should be complemented with 128 GiB of swap on a fast NVMe SSD.

If the windowPoSt task is outsourced to a separate windowPoSt worker, one can expect that both the RAM and swap requirement to just run the lotus-miner process to be lower. See the specific operation requirements for more information about the windowPoSt hardware requirements

Sealing tasks #

Check the specific task hardware requirements table for RAM usage per task.

GPU #

If windowPoSt tasks are not outsourced to a separate windowPoSt worker, a powerful GPU is highly recommended to have on the server that runs the lotus-miner process, as it speeds up the proving tasks significantly.

PC2 #

The PreCommit 2 tasks is significantly faster when running on a GPU compared to when running on the CPU. The minimum VRAM requirement to run the PC2 process on a GPU is 5GiB VRAM.

C2 #

The Commit 2 tasks is significantly faster when running on a GPU compared to when running on the CPU. The minimum VRAM requirement to run the C2 process on a GPU is 11GiB VRAM.

Mixing AMD and Nvidia GPUs in the same machine is known to cause issues with OpenCL and should be avoided. In general Nvidia GPUs have better support then AMD cards.

Disk #

The lotus-miner process in itself does not require a very large disk space. But it is recommended to have the process running on a fast storage medium like a NVMe disk, especially if the windowPoSt process is not outsourced to a separate worker.

PC1 #

Each PreCommit 1 sector will generate data to the amount of 384GiB. Since this sealing task can be write heavy if many sectors are sealing in parallel, it is recommended to use SSDs or NVMe drives.

PC2 #

Each PreCommit 2 task will read all the previously generated data by the PreCommit 1 sealing task, which means that this process is very read heavy. Running this task on NVMe drives with great read speeds are recommended.

C2 #

Each Commit 2 task uses the 16MiB file generated in the Commit1 phase. This process can comfortably be run on SSDs.

Specific operation requirements #

The following table shows what hardware resources are needed to run a single tasks of the given sealing phase or proof calculation:

Future proofing #

The above requirements will not increase in the foreseeable future, and money spent on hardware should provide users with many years of reliable service.
