This document discusses Zero touch on-premise storage infrastructure with OpenStack Cinder. It describes Viettel's IT infrastructure with mixed storage resources and the challenges of managing it. The solution presented uses OpenStack Cinder and additional tools to automate the management and provisioning of block storage for bare metal servers and OpenStack instances. This removes manual configuration steps and improves performance by pre-zoning storage connections. The goal is to make volume management simpler and allow adding new storage resources without additional configuration through the unified management solution.
Room 3 - 1 - Nguyễn Xuân Trường Lâm - Zero touch on-premise storage infrastructure with OpenStack Cinder
- 1. Zero touch on-premise storage infrastructure with OpenStack Cinder Nguyễn Xuân Trường Lâm
- 2. Agenda ● Viettel IT Infrastructure with mixing storage resources ● The solution for management using OpenStack Cinder
- 3. Viettel IT Infrastructure with mixing storage resources
- 4. In Viettel DataCenter Storages Baremetals Cloud Computes SAN Switches
- 5. ❖ Traditional Infrastructure ➢ Risks on many manual configurations to the infrastructure ➢ With many Vendors, different approaches ❖ Cloud Infrastructure ➢ More than 50 volume attachment zoning processes when evacuating if one compute is down Problems on mixing storage resources
- 6. Mapping LUN to a baremetal ❖ Zoning on SAN Switches ● Get WWPN, WWNN of a host ● Add zone ● Add zoneset ➢ Twice on fabric
- 7. ❖ Export LUN ● Create LUN ● Create Host, Initiator ● Export LUN to baremetal Mapping LUN to a baremetal
- 8. The solution using OpenStack Cinder
- 9. Components ★ OpenStack cluster with 2 of 6 core services: Cinder and Keystone ★ Some tools to store WWN information for thoudsands nodes ★ A dashboard to manage all volumes and storage resources ❖ Made of 3
- 10. Source of trust for thousands nodes ❖ Viettel DCIM ● Store all server inventory, including HBA card information ● APIs to get WWN information
- 11. Manage volumes and storage resources ❖ VStorage Administration & Automation - VSA2 ● Volume CRUD ● Allow attach/detach Cinder volumes to baremetals with WWN information collected from DCIM
- 12. Applying the solution ❖ For physical infrastructure ● Simplest provisioning block storage for Baremetals ● Minimum risks by removing any manual configurations on Switches and Storages ❖ To OpenStack Cloud infrastructure ● Pre-persistent zoning for Computes and Storages by attaching a tiny volume ● Remove zoning at Cinder configurations
- 13. Tunning OpenStack ❖ With the removal of zoning on cinder volume configuration ● Nearly also remove block device mapping time ● Save time when action on Compute Instances like creating, deleting, migrating and specially evacuating ➔ Successfully evacuated 40 VMs using SAN backend in one Compute at the same time
- 14. Vision for the solution ❖ Make VSA2 become greater ★ “docker-compose up -d” initiate the whole stack ★ Can do more actions to SAN Switches ★ Be an unified management solution for operating any SANs ★ Cinder volume auto implementation when adding more Storage resources ★ ….
