Which OpenStack component allows management of IBM XIV and IBM DS8884 through a dashboard that gives administrators control while empowering users to provision resources through a web interface?
A. Swift
B. Horizon
C. Cinder
D. Nova
Correct Answer: B
Explanation/Reference:
Horizon is the canonical implementation of OpenStack’s Dashboard, which provides a web based user interface to OpenStack services including Nova, Swift, Keystone, etc.
Incorrect Answers:
A: Swift functions as a distributed, API-accessible storage platform that can be integrated directly into applications or used to store VM images, backups, and archives as well as smaller files, such as photos and email messages.
C: Cinder is the project name for OpenStack Block Storage; it provides persistent block storage to guest virtual machines (VMs). Block storage is often necessary for expandable file systems, maximum performance, and integration with enterprise storage services as well as applications that require access to raw block-level storage.
D: Nova is the OpenStack project that provides a way to provision compute instances (aka virtual servers). Nova supports creating virtual machines, baremetal servers (through the use of ironic), and has limited support for system containers. Nova runs as a set of daemons on top of existing Linux servers to provide that service. References: https://docs.openstack.org/horizon/latest/
