The OCF has multiple physical machines. Some of these are hypervisors, which host virtual servers running on QEMU and KVM. We also have servers that are workers for our Kubernetes cluster, and others comprise our High Performance Computing cluster.
Below is a list of some servers and other hosts at the OCF. VMs are grouped under the hypervisor hosting them.
Hypervisor
KVM hypervisor, purchased 2011. Used for backups.
Hypervisor
KVM hypervisor for production VMs, our main hypervisor since 2017
Virtual Machine
PuppetDB server, stores puppet reports and facts.
Virtual Machine
LDAP and Kerberos server; crucial to the rest of our infrastructure working.
Virtual Machine
Public MariaDB server, used for both users and OCF internal services like print accounting.
Virtual Machine
