Enables native support for HGST Solutions software Spaces as Cinder volumes or snapshots. Each Cinder Volume or Snapshot is mapped to a single HGST Space. This space may be named differently from the actual volume/snap ID and so we store the Space Name<->ID mapping in the volume provider_id. Snapshots are not supported with the current HGST Solutions software, so they are implemented as heavyweight copies in the driver. All Spaces are made visible on the Cinder host for speed of access, and only the spaces requested by Nova instances are actually made visible on other members of the cluster. Not all nodes need SSD storage to take advantage of these volumes, cinder.conf entries specify which nodes share their local SSDs. Prerequisites: HGST Solutions is a software-SAN-like package which allows local SSDs in a cluster to be combined into a single storage pool. The driver has a series of configuration options which must be set in the cinder.conf, prefixed with hgst_*. Nodes should have the HGST software installed and connected to the HGST domain prior to rolling out Nova nodes using this storage. Additional patches required for full functionality (being tracked under the same blueprint): OS-brick patch @ https://review.openstack.org/#/c/186588/ Nova patch @ https://review.openstack.org/#/c/186594/ Nova patch required until os-brick<->nova connection finalized in https://review.openstack.org/#/c/175569/ Change-Id: Ie0ff03856edd4b5610f4412951ea7c970ad63c8c Implements: blueprint add-volume-driver-hgst-solutions |
