(Why) would it be "bad practice" to separate CPU and storage to separate devices? (lemmy.world)

TLDR: I am running some Docker containers on a homelab server, and the containers' volumes are mapped to NFS shares on my NAS. Is that bad performance?

  • I have a Linux PC that acts as my homelab server, and a Synology NAS.
  • The server is fast but has 100GB SSD.
  • The NAS is slow(er) but has oodles of storage.
  • Both devices are wired to their own little gigabit switch, using priority ports.

Of course it's slower to run off HDD drives compared to SSD, but I do not have a large SSD. The question is: (why) would it be "bad practice" to separate CPU and storage this way? Isn't that pretty much what a data center also does?

With each "gate" between the devices, the performance, security and stability suffers additional setbacks and limitations. In your case, you introduced a few new "gates":

  • the connection between NAS, router and your PC (Wifi/cable)
  • router
  • network stability

Of course it's theory, since the actual performance depends on details, he amount and type of data, how you access it and what you're doing with/to it.
