UCS Manager: behind the scenes
UCSM Management Information Model Summary:
• Data Management Engine (DME) contains full representative object model stored in the Management Information Tree (MIT)
• Interaction with DME occurs via Northbound External Interface Layer
• Northbound interfaces all resolve down to XML API
• Application Gateways couple UCSM with end points

UCS XML API Features
XML API
1
Everything is an object
Objects are hierarchically organized
Class identifies object type Card, Port, VNIC…
Class InheritanceServer port is a subclass of port.
A server blade is a subclass of compute entity.
Set of attributes
identity states descriptions
references lifecycle
UCS XML Database contains comprehensive system information Discovered components
System configuration
Operational status including statistics and faults
Managed Objects (MO)
Managed Object
Root
1
Each object is uniquely identified by a DN
Slash delimited sequence of RNs
RNs (Relative Names) are unique within the context they are defined. Example compute blade slot id.
Rn format is defined in naming rules

http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-
central/api/b_UCSC_XML_API_book/b_UCSC_XML_API_book_chapter_01.html
You can use applications developed using this REST (Representational State Transfer) API to do the following:
• Get Cisco UCS Director reports about physical and virtual devices, networks, appliances, groups and users, policies, administration, resource accounting, funds, and other monitored entities within your Cisco UCS domains.
• Invoke orchestrator workflow and task operations.
• Invoke additional operations specific to Cisco UCS Director
