New OpenStack Rocky works on bare metal without server OS

OpenStack continues to conquer the corporate environment. At present, the complex, which unites several Open Source projects and serves the creation of infrastructure of cloud services and cloud storage, operates in 75 public data centers and thousands of private clouds, scaling by 10 million computing cores. However, as noted by the portal ZDNet, OpenStack always pursued two problems - a problematic transfer from one version to another, as well as difficulties with deployment on servers without pre-installed OS, or bare metal. Recently released version of OpenStack 18 Rocky is aimed at eliminating the accumulated shortcomings, as well as introducing new opportunities.

OpenStack open source cloud has always worked well on various hardware architectures - virtual machines (VMs), graphics processors, containers and physical servers, but, as already mentioned, the deployment of OpenStack on bare metal was accompanied by complexities. To simplify this, the OpenStack Ironic service has gained new and improved capabilities for management and automation. In turn, the OpenStack Compute (Nova) service, which is responsible for creating, starting, restarting, stopping the VM, has got support for servers without OSs-that is, users can manage the physical infrastructure in the same way that they manage the VM.

Among other improvements Ironic can include the following:

User BIOS settings: The BIOS is used to initialize the hardware and has many configuration options that support various configuration options. Among other things, they can improve performance, configure power management settings, or enable technologies such as SR-IOV or the Data Plane Development Kit. Ironic is also responsible for configuring the virtualization of network functions;

Groups of conductors: by conductor in Ironic is a service that uses drivers to perform operations on the equipment. The new version of OpenStack has the property conductor group that imposes restrictions on the access of nodes to a specific conductor. This allows users to isolate nodes based on their physical location, which reduces network junctions and increases the security and performance of connections;

RAM interface for disk deployment: Ironic has a new interface for diskless deployments, which can be useful for scalable and high-performance computing. The interface is needed to create instances and quickly deploy large-scale work environments.
