User Guide
4.1 Open Composable API
The Open Composable API is a RESTful interface for OpenFlex that enables a Unified Fabric Control Plane
for Storage Fabric Devices. This allows for composing disaggregated storage resources—with compute,
networking, and memory—into virtual systems in the future. These virtual systems will be dynamically
provided to the right application at the right time, ensuring SLAs can be met automatically.
• Monitor hardware sensors (temperatures, voltages, hardware state)
• Configure hardware (update firmware, reboot individual components or systems, locate LEDs)
• Capture inventory data (serial number, part number, etc.)
• Capture log information
• Configure policies (user access lists, authentication, HTTPS/TLS encryption/security with certificate/key
settings)
• Self-discovery of other locally-available resources configurable using the Open Composable API for
OpenFlex
4.1.1 Accessing the API
The API is accessible on every fabric device connected to the fabric network. The simplest way to access
the API is to find the IP address of the management port on the rear of the Device that contains all of the
other devices. This is set to DHCP by default. Navigating to that IP address from a browser with
added to the end of the IP address will return top level status information.
The IP addresses/API targets listed in this response body will help in navigating the resources available on
this device, as well as provide links and contextual information related to other devices connected on the
fabric.
4.1.2 RESTful API
This API is based on the true REST architectural style meaning that all actions/verbs will be handled
exclusively by the existing HTTP Methods (GET, POST, PUT, DELETE, HEAD, OPTIONS) along with all URI
patterns containing only fully qualified collections of resources and resource instantiations (nouns only, no
action verbs permitted in the URI). HTTP response data is compressed when requested by the browser for
reduced network traffic. OCGUI and in-band management always compress the response data transparent
to the user.
4.1.3 Discovering and Connecting to NVMe Devices using the Open
Composable API
Before you begin: The user needs to use the GUI or the REST API to set/get the IP address of the 100Gb
high-speed links.
Note: This procedure may be used in cases where the network may not detect the IP
addresses of the adapters that will be connected.
