Overview of the ExtremeWare XOS Software

The ExtremeWare XOS software platform is a distributed software architecture. The distributed
architecture consists of separate binary images organized into discreet software modules with
messaging between them. The software and system infrastructure subsystem form the basic framework
of how the ExtremeWare XOS applications interact with each other, including the system startup
sequence, memory allocation, and error events handling. Redundancy and data replication is a built-in
mechanism of ExtremeWare XOS. The system infrastructure provides basic redundancy support and
libraries for all of the ExtremeWare XOS applications.

Like any advanced operating system, ExtremeWare XOS gives you the tools to manage your switch and
create your network configurations. With the introduction of ExtremeWare XOS, the following
enhancements and functionality have been added to the switch operating system:
File system administration
●
Configuration file management
●
Process control
●
Memory protection
●
File system administration-With the enhanced file system, you can move, copy, and delete files from
the switch. The file system structure allows you to keep, save, rename, and maintain multiple copies of
configuration files on the switch. In addition, you can manage other entities of the switch such as
policies and access control lists (ACLs).
Configuration file management-With the enhanced configuration file management, you can oversee
and manage multiple configuration files on your switch. In addition, you can upload, download,
modify, and name configuration files used by the switch.
