Ceph Cluster Hardware Planning & Design Tool
For users deploying a Ceph cluster with their own selected server hardware, proper hardware selection is critical to avoid performance issues or over-specification, ensuring system requirements are met.
The Ceph Cluster Design Tool assists in selecting suitable hardware based on your cluster’s needs.
By entering parameters such as usable HDD/NVMe capacity, disk size, data protection method (Replication or Erasure Coding), and CPU/memory per OSD, the tool provides a solution summary shown on the right side of the page.
