Your Tasks

The data centers behind the IONOS Cloud IaaS consist of hypervisor machines hosting the customer VMs and the storage machines providing the persistent storage. The machines are interconnected via a low latency rdma network. The software side of our storage stack is based on the upstream linux kernel drivers, yet to be open-sourced in-house solutions and the provisioning/cloud orchestration software. Further design and development, maintenance and troubleshooting as well as performance-, reliability- and efficiency- evaluation and optimization of this stack is the task of the platform storage development team.
