This article will demonstrates that how to install and configure Openstack Storage nodes for the Block Storage service (cinder). For the tutorial simplicity , we will use the local disk in LVM as back-end storage. In the upcoming articles ,we will replace the LVM with CEPH storage, once we familiar with cinder services and functionalities. In […]

The Openstack block storage service(cinder) provide the access to the block storage devices to the openstack instances using various back-end storage drivers like LVM ,CEPH etc.  The Block Storage API and scheduler services runs on the openstack controller node and openstack storage node is responsible to provide the volume service. You can configure N-number of […]

Horizon Dashboard is an optional component in Openstack which provides the webpage to launch the instances in few clicks. Horizon is fully depend on openstack core functionalities like keystone (Identify), Glance (Image Service), nova-compute (Compute), and Networking (neutron) or legacy networking (nova-network). Object Storage service can’t be used in dashboard since its a stand alone service. […]

Openstack instances can be launched using command line without using the horizon dashboard service. In this tutorial series, we yet configure horizon. I would like to create the new openstack instance without horizon using command line. To launch an instance, we must at least specify the OS flavour, image name, network, security group, key, and instance […]

This article will demonstrate that how to configure the Neutron configuration on compute node part. The compute node handles the network connectivity and security groups for each instance. In the compute node, we need to enable certain kernel parameters and install the networking components for neutron. Once the required networking components are installed , we just need […]

Configuring the Neutron services in openstack is quite lengthy process since we need to make the necessary configuration changes on controller node (API node), Network node & Compute node. In the previous article , we have configured the neutron services on Openstack controller node. This article will demonstrate that how to configure the Network node […]

Openstack provides two options for networking. The default network type is nova-network which enables the basic networking for the instances.  Nova-network has limitation and it can support only one network  per instance.  The advanced networking option can be obtained using Openstack neutron service.  It supports plug-ins and provides the different networking equipment and software, providing flexibility […]
