ceph cluster

[mguidon]

A ceph storage cluster will be deployed at z43 that replaces the current minio based solution. The cluster will allow decoupling of computational and storage hardware, allow for more storage use cases and improve the backup situation. This is the hardware specific part of #513

Step 1: Initial setup

• Setup of prototype cluster by oetikers on two nodes
• Discussion for 3rd node

Step2: Internal testing

• Familiarize with technology
• S3 compatibility with osparc
• Behavior under high network traffic
• Behavior under failure
• Deploy registry
• Create network shares with token-based access
• How to do backups/versioning
