# NeoFS Storage node configuration file
This section contains detailed NeoFS Storage node configuration file description
including default config values and some tips to set up configurable values.
There are some custom types used for brevity:
1. `duration` -- string consisting of a number and a suffix. Suffix examples include `s` (seconds), `m` (minutes), `ms` (milliseconds).
2. `size` -- string consisting of a number and a suffix. Suffix examples include `b` (bytes, default), `k` (kibibytes), `m` (mebibytes), `g` (gibibytes).
3. `file mode` -- octal number. Usually, it starts with `0` and contain 3 digits, corresponding to file access permissions for user, group and others.
4. `public key` -- hex-encoded public key
5. `hash160` -- hex-encoded 20-byte hash of a deployed contract.
