+Infrastructure Overview (INF)
+=============================
-This project implements a real time platform to deploy the O-CU and O-DU.
+This project implements a real time platform (rtp) to deploy the O-CU and O-DU.
-In O-RAN architecture, the O-DU and O-CU could have different deployed scenarios.
-In general the performance sensitive parts of the 5G stack require real time platform,
+In O-RAN architecture, the O-DU and O-CU could have different deployed scenarios.
+The could be container based or VM based, in this release, we only cover the container one.
+In general the performance sensitive parts of the 5G stack require real time platform,
+especially for O-DU, the L1 and L2 are requiring the real time feature,
the platform should support the Preemptive Scheduling feature.
-
-For example, from implementation perspective, the non-virtualized DU,
-VM based DU and container based DU are requiring a real time host system.
+
Following requirements are going to address the container based solution:
-1.Support Node Feature Discovery
-
+1.Support the real time kernel
-2.Support CPU Affinity and Isolation
+2.Support Node Feature Discovery
+3.Support CPU Affinity and Isolation
-3.Support Dynamic HugePages Allocation
+4.Support Dynamic HugePages Allocation
And for the network requirements, the following should be supported:
+
1.Multiple Networking Interface
2.High performance data plane including the DPDK based vswitch and PCI pass-through/SR-IOV.
-This is based on Yocto/OpenEmbedded, so it includes a Yocto/OpenEmbedded compatible
-layers meta-oran and wrapper scripts to pull all required Yocto/OE layers to build
-out the reference platform.
+In the Bronze release, the following components and services are enabled:
+
+1. Fault Management
+
+ - Framework for infrastructure services to raise and persist alarm and event data.
+
+ - Set, clear and query customer alarms
+
+ - Generate customer logs for significant events
+
+ - Maintains an Active Alarm List
+
+ - Provides REST API to query alarms and events, also available through SNMP traps
+
+ - Support for alarm suppression
+
+ - Operator alarms
+
+ - On platform nodes and resources
+
+ - On hosted virtual resources
+
+ - Operator logs - Event List
+
+ - Logging of sets/clears of alarms
+
+ - Related to platform nodes and resources
+
+ - Related to hosted virtual resources
+
+2. Configuration Management
+
+ - Manages Installation and Commissioning
+
+ - Auto-discover of new nodes
+
+ - Full Infrastructure management
+
+ - Manage installation parameters (i.e. console, root disks)
+
+ - Nodal Configuration
+
+ - Node role, role profiles
+
+ - Core, memory (including huge page) assignments
+
+ - Network Interfaces and storage assignments
+
+ - Hardware Discovery
+
+ - CPU/cores, SMT, processors, memory, huge pages
+
+ - Storage, ports
+
+ - GPUs, storage, Crypto/compression H/W
+
+3. Software Management
+
+ - Manages Installation and Commissioning
+
+ - Auto-discover of new nodes
+
+ - Full Infrastructure management
+
+ - Manage installation parameters (i.e. console, root disks)
+
+ - Nodal Configuration
+
+ - Node role, role profiles
+
+ - Core, memory (including huge page) assignments
+
+ - Network Interfaces and storage assignments
+
+ - Hardware Discovery
+
+ - CPU/cores, SMT, processors, memory, huge pages
+
+ - Storage, ports
+
+ - GPUs, storage, Crypto/compression H/W
+4. Host Management
+
+ - Full life-cycle and availability management of the physical hosts
+
+ - Detects and automatically handles host failures and initiates recovery
+
+ - Monitoring and fault reporting for:
+
+ - Cluster connectivity
+
+ - Critical process failures
+
+ - Resource utilization thresholds, interface states
+
+ - H/W fault / sensors, host watchdog
+
+ - Activity progress reporting
+
+ - Interfaces with board management (BMC)
+
+ - For out of band reset
+
+ - Power-on/off
+
+ - H/W sensor monitoring
+5. Service Management
+
+ - Manages high availability of critical infrastructure and cluster services
+
+ - Supports many redundancy models: N, or N+M
+
+ - Active or passive monitoring of services
+
+ - Allows for specifying the impact of a service failure and escalation policy
+
+ - Automatically recovers failed services
+
+ - Uses multiple messaging paths to avoid split-brain communication failures
+
+ - Up to 3 independent communication paths
+
+ - LAG can also be configured for multi-link protection of each path
+
+ - Messages are authenticated using HMAC
+
+ - SHA-512 if configured / enabled on an interface by-interface basis
+6. Support the ansible bootstrap to implement the zero touch provisioning
+
+Enable the ansible configuration functions for infrastructure itself including the image installation and service configuration.
+
+
+NOTE: These features leverage the StarlingX (www.starlingx.io). And in Bronze release, these features are only avalaible for IA platform.
+
+NOTE: In this release single server solution is supported only. All the functionalities include controller functions, storage functions and compute functions are integrated in the single server.
