Our OpenStack based private cloud provides a platform for researchers and students supporting various research and teaching activities. The underlying hardware for hosting virtual machines consists of five identically configured servers, each equipped with two Intel Xeon E5-2650v2 CPUs and 128 GB main memory. For hosting controlling and management services, we employ a single server with one Intel Xeon E5-2650v2 CPU and 32 GB main memory. All CPUs have eight cores operating at 2.6 GHz. Moreover, each server is a member of our Ceph cluster, a distributed storage system for our cloud installation. The servers are connected by multiple networks separating management, storage, and tenant VM communication. Specifically, all self-service virtual networks connecting tenant VMs,  as well as the storage network, are operated on a 10 GBit/s physical ethernet network.

For administration we employ several tools, like a web-based GUI for software administration, called Cockpit, as well as an iRMC suite for hardware administration.
