OpenStack
Managing OpenStack Clusters
• Managing OpenStack Clusters even more difficult then other types of clusters
• Without proper infrastructure, OpenStack will not be able to run
• Setting up OpenStack manually is often extremely complex for production setups
• Bright Cluster Manager provides single-pane-of-glass to manage and monitor all aspects of OpenStack cluster
• Includes:
• Hardware (set up, configuration, monitoring)
• Operating system (provisioning, updates)
• OpenStack installation
• OpenStack configuration
• Bright Cluster Manager provides perfect environment for OpenStack to run on
16
Ease of Installation
• Deploying OpenStack private clouds made simple
• Bright pre-packages OpenStack (Icehouse) on the DVD
• Bright installs Linux, OpenStack & itself
• OpenStack can be enabled during installation or afterwards
• OpenStack will run as services on top of Bright cluster
• Bright configures, manages and monitors physical cluster (hardware + OS + other middleware)
• Virtual Machines are managed through OpenStack
• Support various network setups (VLAN, VxLAN, flat, etc.)
• Bright integrates with Ceph, can be used for OpenStack
36
OpenStack Configuration
OpenStack configuration through roles
• OpenStack consists of several services to accomplish specific tasks
• Tasks can be assigned by assigning roles to nodes
• Example roles:
Compute (Nova) Image (Glance)
Block Storage (Cinder) Dashboard (Horizon) Auth (Keystone) Networking (Neutron)
• Assigning/unassigning role will:
• Write out config file based on role parameters
• Start/stop/monitor relevant services
• Add/remove entries to Keystone service registry
• OpenStack configuration is dynamically updated with cluster changes (e.g. hostname, network settings)
USE CASE: problem
Developers need clusters to test their code
Support engineers need clusters to reproduce issues Need to quickly spin up clusters with:
• Different version of Bright, including custom builds
• Different base distributions (eg RedHat, CentOS, SUSE, etc.)
• Different types of configurations
Limited amount of hardware available
38
USE CASE: solution
We drink our own Champagne Build our own private cloud
Runs Bright to manage the hardware and OS Use Bright to deploy and configure OpenStack
Create set of end-user tools to spin up virtual clusters
• Command-line driven
• Make use of OpenStack API’s
• Use web based dashboards for console access
Each user has an isolated environment
Users have full control over their virtual clusters
Virtual clusters directly accessible from office network Load is balanced automatically
USE CASE: plans & considerations
Automated virtual head node installation Automated nightly installationsHead node installation using volume snapshots
Works in POC and allows big clusters to spin up in minutes Make sure you have a fast network

OpenStack in HPC
• Improved flexibility
• User can manage their code, libs, etc.
• OpenStack Ironic also allows non-virtualized instances to be created
• SR-IOV allows HPC resources (e.g. InfiniBand and GPU) to be made available directly to VMs at near-native performance (work in progress)
Conclusion
• Bright provides tried & tested method of cluster management
• Hundreds of clusters world-wide being managed using Bright Cluster Manager
• Inclusion of OpenStack management capabilities provides complete solution for setup, management & monitoring of OpenStack based private clouds.
• Single pane of glass for management of cluster & OpenStack
• Especially well suited for clusters that run various workloads (e.g. OpenStack, HPC compute, Hadoop)
