OpenStack Ironic is a framework for bare metal provisioning, allowing users to deploy workloads on actual physical servers rather than virtual machines, thus addressing specific performance and hardware needs. It features various components such as ironic-api and ironic-conductor, with support from multiple vendors to manage diverse hardware. Fujitsu plays a significant role in the community by contributing to new features and integrating their hardware into the Ironic framework.
Ironic - Vietnam OpenStack Technical Meetup #12
- 1. OpenStack Baremetal provisioning with Ironic 12 Nov 2016 Dao Cong Tien (irc: tiendc, email: [email protected]) Fujitsu Vietnam Limited Copyright 2016 Fujitsu Vietnam Limited
- 2. Agenda 1 • Ironic introduction • Ironic overview • Ironic works by community • Ironic works by Fujitsu • Q&A Copyright 2016 Fujitsu Vietnam Limited
- 3. Agenda 2 • Ironic introduction • What is Ironic? • Why need Ironic? • Ironic overview • Ironic works by community • Ironic works by Fujitsu • Q&A Copyright 2016 Fujitsu Vietnam Limited
- 4. Ironic introduction 3 OpenStack Ironic is a set of projects that perform bare metal provisioning and related activities. Ironic is a virt driver for Nova like libvirt, xen, hyperv, … Ironic virt dirver starts a Nova instance in a real machine instead of virtual ones. Copyright 2016 Fujitsu Vietnam Limited
- 5. Ironic introduction 4 Why do we need Ironic? In some cases, user has some requirements: • User prefers to have an actual, physical server • User wants to use hardware directly • User wants to deploy the workloads with higher performance Why do user need bare metal service? • Mission-critical legacy applications that aren’t designed for cloud architectures • Real-time and “near real-time” systems • HPC (High-Performance computing) • BigData and related Data Science and Machine Learning projects • Tasks accessing devices and resources that cannot be virtualized What do Ironic provide? Ironic brings the advantages of both bare metal and virtualization: performance and manageability. Copyright 2016 Fujitsu Vietnam Limited

Ironic overview – Components 8 Ironic main components: ironic-api and ironic-conductor python-ironicclient is a Python client program ironic-python-agent is an agent (small program) that is launched inside the Bootstrap image. It prepares a node for deployment and downloads the target system image. ironic-inspector helps with hardware introspection. bifrost, ironic-webclient, ironic-ui, ironic-lib, pyghmi… Copyright 2016 Fujitsu Vietnam Limited
- 10. Ironic overview – Key technologies 9 PXE – Preboot Execution Environment. Booting computers via a network. NBP – Network Bootstrap Program is responsible for loading the OS kernel into memory so that the OS can be bootstrapped over a network. IPMI – Intelligent Platform Management Interface is a standardized computer system interface used by system administrators for out-of-band management of computer systems and monitoring. DHCP – Using PXE, the BIOS uses DHCP to obtain an IP address for the network interface and to locate the server that stores the network bootstrap program (NBP). TFTP – Trivial File Transfer Protocol. TFTP is used to download NBP over the network using information from the DHCP server. iSCSI – Internet Small Computer Systems Interface is used to copy an image to the target machine local disk.

- 12. Ironic overview – Vendor Drivers 11 Many vendors have contribution to Ironic to make Ironic support their hardware. Cisco (UCS drivers) Cray (pxe_snmp driver) Dell (DRAC drivers) Fujitsu (iRMC drivers) HP, HPE (iLO, OneView drivers) IBM (pxe_ipminative driver) SeaMicro (SeaMicro drivers) NOTE: Ironic provides some generic drivers that can support provisioning a wide range of hardware from multiple vendors even there is no equivalent vendor driver. Eg. Using driver pxe_ipmitool may provision hardware that supports PXE and IPMI. Copyright 2016 Fujitsu Vietnam Limited
