OpenStack (x86_64, POWER, & AARCH64)

This wiki provides resources to deploy and manage instances on our OpenStack clusters.

We curently have 3 OpenStack clusters at the OSL: x86_64, POWER, and AARCH64. The x86 cluster is used typically for production hosting while the other two are mainly used to support development and CI for those architectures. All 3 clusters run OpenStack powered by KVM.

OpenStack Dashboards:

• x86_64 cluster

• OpenPOWER cluster

• AARCH64 cluster
