DFINITY strongly recommends using hardware that meets the exact specification for hardware components.
To simplify:
- System must be one of {Dell, Supermicro[0], Gigabyte[0], ASUS[1], HPE[1]}
- Processors must be Dual AMD EPYC Milan. Minimum model number: 7313 (higher end models are OK)
- RAM must be 16x 32GB 3200 MT/s. All from the same manufacturer. Don’t mix and match.
- SSD’s must be 5x 6.4TB mixed mode NVMe (DWPD >=3). All from the same manufacturer. Don’t mix and match.
- Must have dual port 10G SFP or BASE-T
- Must have TPM 2.0
Choice of manufacturer of SSD or RAM can be decided by the NP. These choices may be constrained by the vendor.
Deviate from this specification at your own risk. DFINITY does not provide hardware support or troubleshooting. Deviating from the spec will cause issues during installation of node software and risks losing NP rewards.
You may have noticed the previous validated configurations for Supermicro and Gigabyte had deviated from the specification by either doubling the size of each RAM stick or using 7.68TB SSD’s (DWPD ~=1). We don’t recommend doing this. Sorry if that caused confusion.
[0] We will re-run validation on the Gigabyte and Supermicro with components which meet the exact specification.
[1] SEV-SNP validation is still pending for the ASUS configuration. Complete validation is still pending for HPE.
