Database servers using NAS as storage? (alien.top)

I am thinking of running multiple database/messages servers such as postgres, redis, mongo, influxdb on old computers and use a centralized NAS to store the data.

One advantage is that I don't need to worry about getting appropriate local storage for the computers that host these services. For example, I could run postgres on an old desktop with spinning disks or even a raspberry pi.

But I am still concerned about the I/O speed and reliability. I wonder if anyone has experience doing it like this. Can you share the pros and cons? I really appreciate it.

If your NAS can keep up and your networking gear can keep up…. It might work for you.

You need to give a better info about what you have, what you want to run, and how you want to run it. How tolerant of data loss are you in there event of hardware failure?

I feel like if you have an excess of old machines and a NAS a kube cluster might be your next stop.
