Abstract

Disclosed is a software representation of a dense server / chassis topology. This is a dynamic, multi-level, and scalable representation which can be used to manage and monitor all current and future subsytems within a dense server / chassis environment.

Chassis environment topology maping for system management

    With the development of a BladeCenter chassis, where multiple systems and their subsystems are configured together in a dense environment with inter-system dependencies, management of the chassis as a whole requires the knowledge and inter-connection mapping of various components within the chassis. Since almost all the components in the chassis environment are either hot-pluggable, hot-swappable, or have redundant components for fail-over, these topology maps should have the capacity to be dynamically updated. In addition, with popularity of the chassis environment and addition of new components and subsystems, the chassis topology maps should be able to scale both horizontally and vertically. Therefore, a dynamic, multi-level, and scalable chassis topology is necessary when it comes to managing chassis or dense server environments.

    The solution involves the definition of a generic subsystem object along with various subsystem types, which broadly categorizes the modules in the chassis environment. The subsystem type is designed for multi-level categorization based on models, functions, protocols, etc., to provide granular information (Figure 1). For example, in the chassis environment a switch module type can further be categorized as, Ethernet switch module, Fiber Channel switch module, etc (Figure 2). A unique feature about these subsystem types is the ability to identify them interchangeably either at...
