OpenStack Summit; Operations Track November 7th, 2013 AsiaWorld-Expo, Hong Kong Mark Detrick – Brocade & Gary Thunquest – HP Taking Advantage of Fibre Channel SAN Infrastructure in OpenStack Environments

Openstack Summit in Hong Kong Agenda Why is FC support important? Blueprints What is planned for the Icehouse release? FC Zoning A Proof of Concept November 2013 Openstack Summit in Hong Kong

Why is FC support important? Leverage existing FC environments Simplified Zone Management Automatic detection of zone configuration Automatic detection of SAN context Automatic application to current active zone set No manual intervention To take advantage of FC storage benefits Performance Resiliency Security Support requirements for block storage applications November 2013 Openstack Summit in Hong Kong

FC Support Architecture

FC Block Storage Initiatives 2 Blueprints FC Block Storage No automated zoning Blueprint approved Implemented in Grizzly FC SAN Zone Controller Blueprint Contains automated zoning Coding – work in progress Icehouse release November 2013 Openstack Summit in Hong Kong

FC Support in OpenStack Cinder Volume Manager Available in Cinder’s block storage services FC Volume Driver Storage vendors’ specific driver FC SAN Lookup Service New: required to associate correct storage ports with compute pWWN FC Zone Manager Zone lifecycle management FC Zone Driver Fabric vendors’ specific driver November 2013 Openstack Summit in Hong Kong

FC Support with OpenStack Volume/Zone Manager Operations Nova makes a volume request to Cinder Cinder’s Volume Manager gathers Initiator/Target WWN map info Volume Manager calls FC Zone Manager (zoning is enabled) FC Zone Mgr + FC Zone Driver provide initiator/target access control Cinder’s Volume Mgr completes request by providing connectivity info to Nova November 2013 Openstack Summit in Hong Kong

FC Zoning

FC Support in OpenStack Zone Lifecycle Management Operations Zoning Modes Fabric Volume Manager is responsible for configuration of zoning None Volume Manager is not responsible for configuration of zoning Manual or other automated process may be used (e.g., Peer Zoning) In an Active Zone Set… Add/Update a zone Remove a zone Read/Get a zone November 2013 Openstack Summit in Hong Kong

FC Support with OpenStack FC Zoning Single Initiator Zoning Single initiator with multiple targets per zone Volume attach operation could result in: Adding a new zone to the active zone set Updating an existing zone already in use Single Initiator & Target Zoning Single initiator to a single target Every volume attach operation could result in a new zone Zoning for multiple FC fabrics/SANs Automatically determine the fabric/SAN context to apply zone config November 2013 Openstack Summit in Hong Kong

FC Support with OpenStack FC Zone Manager Zoning mode “fabric” and volume driver type “fibre_channel” Instantiates appropriate vendor specific FC Zone Driver Delegates the zoning responsibility to the proper FC Zone Driver The Brocade FC Zone Driver supports zoning for Brocade products November 2013 Openstack Summit in Hong Kong
