Overview

Swarm Cluster Services (SCS) is a replacement for CSN but in a modernized form that is easy to install and maintain. It provides multiple services bundling them into a single package for booting and configuring Swarm storage.

Some of the major services that SCS provides are:

PXE booting
Configuration management
Logging server
DHCP
NTP
