Described are techniques for request processing. A server receives from a client a request for first data to be returned to the client. The first data includes a first property of an object. The object is included in an object model and includes a predefined property. The first property is not a predefined property of the object and is a new property defined using an expression included in the request. The request includes any of the predefined property and a constant. First processing is performed at the server to service the request and obtain the first data. At the server in accordance with the first processing, a response to the request including the first data is generated.

Defining new properties using expressions in API calls

Described are techniques for consolidating tasks into a composite job. A server processes a composite request to create a composite job on the server. The composite request comprises a plurality of nested job create requests. The composite job comprises a plurality of jobs. Each job in the plurality of jobs corresponds to a job create request in the plurality of nested job create requests. The server generates a dependency tree indicating a dependency of each job in the plurality of jobs. The server executes the composite job in accordance with the dependency tree. On determining that a first job is dependent on a second job, the server executes the second job prior to executing the first job. The server passes the output of the second job as input to the first job.

Consolidating tasks into a composite request

Described is a method and system for use in evaluating management operations. A current storage configuration in connection with a data storage system is captured. A management operation event relating to the data storage system is simulated without affecting the data storage system. The management operation event is simulated using the current storage configuration in connection with the data storage system. A management operation event output is provided for enabling evaluation of the potential affect of the management operation event in the data storage system in response to simulating the management operation.

Evaluating management operations

There is disclosed a method and system for use in evaluating a system event. A current storage configuration is captured in connection with a data storage system. A system failure event relating to the data storage system is simulated without impacting the data storage system. The system failure event is simulated using the current storage configuration in connection with the data storage system. A system failure event output is provided for enabling evaluation of the potential impact of the system failure event in the data storage system in response to simulating the system failure event.

Evaluating a system event

Described are techniques for searching. Search criteria including parameters is received. It is determined whether to perform searching based on storage provisioned for one or more selected applications identified in the search criteria. If it is determined to perform searching based on storage provisioned for one or more selected applications, first processing is performed in accordance with the search criteria, and otherwise second processing is performed in accordance with the search criteria. Search results produced as a result of one of the first processing and the second processing are received.
