## 8.2 Management Console software 

The MC, which is based on Linux, includes the following application servers: 

GLYPH<SM590000> DS Management GUI 

The DS GUI server is used to perform configuration and management tasks. 

GLYPH<SM590000> IBM Enterprise Storage Server Network Interface (ESSNI) server 

ESSNI is the logical server that communicates with the DS GUI server and interacts with the two processor nodes of the DS8880. It is also referred to as the DS Network Interface (DSNI). 

GLYPH<SM590000> RESTful Application Programming Interface (API) services 

The DS8880 provides industry-standard Representational State Transfer (RESTful) API services for management applications and RESTful clients. RESTful services are running on the MC and can be upgraded without requiring a DS8880 LIC update. 

The DS8880 MC provides the following management interfaces: 

GLYPH<SM590000> DS Management Graphical User Interface (GUI) 

GLYPH<SM590000> Data Storage Command-Line Interface (DS CLI) 

GLYPH<SM590000> DS Open Application Programming Interface (DS Open API) 

GLYPH<SM590000> RESTful Application Programming Interface (RESTful API) 

GLYPH<SM590000> Web-based User Interface (Web UI or WUI) 

GLYPH<SM590000> Copy Services Manager interface (CSM) 

GLYPH<SM590000> LDAP proxy through CSM 

The GUI and the DS CLI are comprehensive, easy-to-use interfaces for a storage administrator to perform DS8880 management tasks to provision the storage arrays, manage application users, and change MC options. The interfaces can be used interchangeably, depending on the particular task. 

The DS Open API provides an interface for external storage management programs, such as IBM Spectrum Control, to communicate with the DS8880. It channels traffic through the IBM System Storage Common Information Model (CIM) agent, which is a middleware application that provides a CIM-compliant interface. 

Similar to DS Open API, the RESTful API services provide an interface for external management programs and applications to interact with the DS8880. Clients can develop and tailor their specific DS8880 management applications based on the standard RESTful APIs.
