# FrostFS Storage node configuration file
|
|
|
|
This section contains detailed FrostFS 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.
|
|
|
