My main node is self-hosted with the following specs:
- Ryzen 3600 (soon to be upgraded to 5800x)
- 64 GB DDR4 RAM (48GB dedicated to Radix)
- 2TB Samsung 980 PRO NVMe SSD
- 2TB HDD for backups
- 1500VA UPS
- 1Gbit/s fiber connection
which costed me approximately 1200€. (most of which were the SSD and RAM)
I have two backup nodes on Hetzner which cost me a total of 82€ a month, with similar spec, but smaller (and cheaper) SSD.
Monitoring is done via Grafana Agent so no need for an additional server for that.
I expect my main server to last three years (maybe even more), with the most likely component to fail being the SSD (sadly most expensive one…). See all my struggles with stopping radixdlt-node from destroying my SSD here.
I also had a 4G failover on my main node but I removed that because failing over to the 4G modem was too slow and buggy, now I just switch to the backup nodes.
Considering a lifespan of 36 months before needing upgrades or replacement I would put the cost to a bit more than 35€ a month, including power costs, excluding my Internet bill.
I would put my total costs at 120€~ a month, but I’m running an unusual self-hosted setup, still maintaining very good uptime though imo.
I also think the subsidy is enough.
