Best and simplest tradeoffs when installing additional NAS

When installing additional NAS to an existing network, what is the best way to do it? Add to the existing partitions? How would it affect the existing NAS?

There's always a tradeoff between simplest and best. Usually, simplest wins out. The simple way is to just install another NAS box with a new IP address and manage it independently and as a separate file system(s).

If you want to combine the file system with others, use a distributed file system or additional mount points. If you just want to add capacity to your existing NAS, assuming it supports it, just add the storage and use the tools to either extend the file system(s) or create new ones.

Remember, your performance probably won't be improved in this case. Actually, it will probably be negatively affected because you've added capacity without increasing the processing power or the number of network interfaces.
