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, fan speeds, hardware state)
• Configure hardware (update firmware, reboot individual components or systems, assert 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 Chassis 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.
Query/
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).
4.2 In-band Enclosure Management
The OpenFlex Data24 provides In-Band Enclosure Management functionality through the OCAPI. To leverage
the In-Band Management features, users must install a standalone version of the OCAPI onto an initiator
or host and connect a management device that is presented up to the fabric via the IOM enclosure
manager(EM) and discoverable using

4.3 NVMe-CLI
NVMe-CLI is an open-source management tool for NVMe storage devices in Linux®. The tool allows users to
manage device firmware, erase data securely, output error logs, and other similar management functions. It
is a command-line utility and can be used to script management functions for large storage arrays.
