Aggregate Managers

In OMF, Aggregate Managers (AM) are software components used for management of various testbed resources. Each AM implements a set of services that are organized in service group as specified in the ​AM API. Following OMF 5.5 AMs are available in ORBIT:

• Inventory - manager responsible for description of testbed resurces and configurations needed by other managers
• Chassis Manager Controller - group of services related to power and status management (of nodes and other testbed resources)
• PXE - AM that supports network booting of nodes
• Frisbee - services used for loading node image
• SaveImage - service group used for saving node image
• Accounting and Scheduling - collection of service groups that provides access control management including scheduling
• Scheduler - service group facilitate scheduling
• Result - services that are used to retrieve experimental results from the OML database
• Status - services that are used to show ​status of various domains
• Interference - AM that manages interference injection in the grid
• Intrumentation - AM that manages RF Test System in Sanbox 4 testbed domain
• WiMAX RF - group of services used to manage WiMAX Base Station
• Delegated Account Management - service group that facilitates delegated account management

(in earlier versions of OMF, AMs were also known as "gridservices").
