It provides a familiar yet powerful interface for the management of servers, storage systems, and other devices.

Reading from Sysman files obtains active information from devices being managed by Sysman. Writing to Sysman files initiates tasks such as turning on/off server blades, discovering new devices, and changing the boot order of a blade. The combination of the file access semantics and existing UNIX utilities such as grep and find that operate on multiple files allow the creation of very short but powerful system management procedures for large clusters. Sysman is an extensible framework and has a simple interface through which new system management procedures can be easily added. We show that by ...
