5 OpenSAF System Management Model (continued…) System configuration flow at Initialization time Management Access Server (MAS) BAM MAA Persistent Store Server (PSS) System Description XML 1.Initial configuration is read from XML (NCSSystemBOM.xml) by BAM and is fed to MAS. 2.MAS sends this configuration to OAA (of AvD and AvM) and PSS. 3.The Availability director (AvD) distributes their configuration to node directors when they come up, and node director enforces it on its node. AVSV AvD AvM OAA

6 OpenSAF System Management Model (continued…) System Model Consumed at Run Time Management Access Server CLI MAA Persistent Store Server (PSS) 1.Configuration to the system can be added by user at run time by SNMP MIB sets. Modifications have semantic limitations. 2.Persistent configuration can be retrieved from PSS. SNMP Master Agent SNMP Sub-Agent AVSV MAA AvM AvD OAA

10 AMF Integration with IMM When will it happen? Information Model Management (IMM) Service exists in OpenSAF Integration of AMF with IMMSv will be done in OpenSAF release.

11 AMF Integration with IMM System configuration flow at Initialization time IMM System Description XML (imm.xml) 1.Initial configuration is read from XML (containing System deployment configuration) by IMMSv and is retrieved by AMF from IMMSv. 2.The Availability director (AvD) distributes their configuration to node directors when they come up, and node director enforces it on its node. AVSV AvD AvM OI & OM

12 AMF Integration with IMM Configuration can be fed to the system dynamically by any IMMSv-OM (such as CLI, SNMP) which will forward it to respective OI (AMF in case of AMF entities). System Model Consumed at Run Time IMM CLI OM SNMP Master Agent SNMP Sub-Agent OM AVSV AvD AvM OI System Description XML (imm.xml)

14 Integration Impact on AMF Interface Removal: Interface of AMF with PSSv will get removed. –AMF shall rely on IMMSv for persistency of objects. Interface of AMF with MASv will get removed.

15 Integration Impact on AMF Addition of Interaction between AMF and IMM: using Object Management APIs using Object Implementer APIs Responding to CCB & Admin Operation callbacks Responding to Runtime Objects Management callbacks

16 Integration Impact on AMF SNMP interface with AMF: It is currently supported by MASV which will be removed. It can be supported if SNMP Sub-Agent becomes an IMM-OM.

17 Integration Impact on AMF Compatibility Issues: Currently AMF is B compliant. Currently IMMSv is A compliant, which supports AMF B Information Model. So, AMF will support B Information Model.

19 Integration Impact on Applications It need become an IMM-OI/OM. It need to deprecate existing MASV interface. Same can be done in other SAF Services like CPSV, GLSV, etc.
