Welcome to Mirantis OpenStack Documentation — Mirantis OpenStack v6.1. Reference Architectures — Mirantis OpenStack v6.0. OpenStack Environment Architecture Fuel deploys an OpenStack Environment with nodes that provide a specific set of functionality.
Beginning with Fuel 5.0, a single architecture model can support HA (High Availability) and non-HA deployments; you can deploy a non-HA environment and then add additional nodes to implement HA rather than needing to redeploy the environment from scratch. The OpenStack environment consists of multiple physical server nodes (or an equivalent VM), each of which is one of the following node types: Controller: The Controller manages all activities in the environment. nova-controller maintains the life cycle of the Controller. along with RabbitMQ, HAProxy, MySQL/Galera, the Pacemaker Cluster (Corosync and Pacemaker), Keystone, Glance, and Cinder.
Compute: Note In environments that Fuel deploys using vCenter as the hypervisor, the Nova-compute service can run only on Controller nodes. Storage: OpenStack requires block and object storage to be provisioned. Service Chaining using Neutron Networks Implemented as Standard Compliant Layer 3 VPNs. OpenStack Docs: ML2 plug-in. How to enable SCTP traffic in Icehouse - Ask OpenStack: Q&A Site for OpenStack Users and Developers. Hi I have configured two servers.
One act as a SCTP Server and other act as a SCTP Client. Client send SCTP request to server but from server end couldn't see any traffic coming from the client. Please help me to sort this issue. *netstat -nap | grep sctp* sctp 10.210.10.131:55600 LISTEN 23515/sctp_test *tcpdump -ni any sctp* tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on any, link-type LINUX_SLL (Linux cooked), capture size 65535 bytes ------------------------ Nothing -------------------------------- OpenStack Neutron — Network Technologies in Distributed Computing Systems. Chapter 1. Example Architectures - OpenStack Operations Guide.
This particular example architecture has been upgraded from Grizzly to Havana and tested in production environments where many public IP addresses are available for assignment to multiple instances.
You can find a second example architecture that uses OpenStack Networking (neutron) after this section. Each example offers high availability, meaning that if a particular node goes down, another node with the same configuration can take over the tasks so that service continues to be available. The simplest architecture you can build upon for Compute has a single cloud controller and multiple compute nodes. The simplest architecture for Object Storage has five nodes: one for identifying users and proxying requests to the API, then four for storage itself to provide enough replication for eventual consistency. An asterisk (*) indicates when the example architecture deviates from the settings of a default installation. MySQL follows a similar trend. Diving into OpenStack Network Architecture - Part 1 (Ronen Kofman's Blog)
OpenStack networking has very powerful capabilities but at the same time it is quite complicated.
In this blog series we will review an existing OpenStack setup using the Oracle OpenStack Tech Preview and explain the different network components through use cases and examples. The goal is to show how the different pieces come together and provide a bigger picture view of the network architecture in OpenStack. This can be very helpful to users making their first steps in OpenStack or anyone wishes to understand how networking works in this environment. We will go through the basics first and build the examples as we go. According to the recent Icehouse user survey and the one before it, Neutron with Open vSwitch plug-in is the most widely used network setup both in production and in POCs (in terms of number of customers) and so in this blog series we will analyze this specific OpenStack networking setup. Neutron/LBaaS/Architecture. This document describes the internal architecture of LBaaS and workflows.
Modules Decomposition LBaaS architecture is based on advanced services introduced into Quantum. The structure is following: LBaaS Quantum Extension - is responsible for handling REST API calls (BP: lbaas-restapi-tenant) LBaaS Quantum AdvSvc Plugin - is a core of service, it is responsible for: (BP: lbaas-plugin-api-crud) DB storage Request validation Scheduling of load balancing services (deployment to LB devices) LBaaS Agent - is stand-alone service that manages drivers (BP: lbaas-agent-and-rpc) Driver - is a module that transforms LBaaS object model into vendor-specific model and deploys configuration onto load-balancing device (BP: lbaas-driver-api) Workflow LBaaS management is performed via REST API.
There are two types of locks: Object-level lock is done on an instance (vip, pool, member) and restricts concurrent changes. Ordinary update workflow is: Driver API See Quantum/LBaaS/DriverAPI for details. Openstack-ops-manual. Openstackneutron.pdf.
