Purpose
This enhancement will provide a basic implementation of a resolver for the SDD Runtime that can process and resolve file system properties as modeled in a SDD.
Requirements
- Based on the CIM type of CIM_FileSystem, the resolver must be able to recognize the type of file system being utilized.
- Typically, the operating system must be known in order to determine the proper method of utilizing and asking for file system properties.
- The resolver must be able to provide a core set of property handlers.
- The resolver must be able to check to see if a defined file system resource meets minimum and maximum size requirements.
- The resolver must be able to determine if a defined file system resource is hosted by the the parent of defined resource in topology.
- The resolver must be able to determine if a defined file system resource exists.
- Interfaces to the class must adhere to a common api for existing in the Profile Module.
Design details
- "FileSystemResolver" will take the file system properties defined in the SDD and see if the conditions that are required can be satisfied.
- This resolver will use other defined resources in topology of the SDD to validate the existance.
- Resolution of file system properties often will require other resources in topology to be resolved.
Known Limitations
Impacts of this enhancement
- The SDD runtime will be able to interact with defined topology file system services and use this data to help in resolution of defined SDD resources and requirements on the defined service.
