Physical component list
Review the minimum configuration of physical components recommended for deploying a CDP Private Cloud Base cluster.
| Component | Configuration | Description | Quantity |
|---|---|---|---|
| Physical servers | Two-socket, 8-16 cores per socket, > 2 GHz; minimum 128 GB RAM. | Hosts the various cluster components. | Based on cluster design. |
| NICs | 10 Gbps Ethernet NICs (minimum required). | Provides the data network services for the cluster. | At least one per server, although two NICs can be bonded for additional throughput. |
| Internal HDDs | 500 GB HDD or SSD/NVMe recommended for operating system and logs; HDD for data disks (size varies with data volume requirements). SSD/NVMe can be used for YARN local directories. | Ensures continuity of service on server resets and contains the cluster data. | 10-24 disks per physical server. The largest storage density currently supported is 100 TB per DataNode. |
| Ethernet ToR/leaf switches | Minimum 10 Gbps switches with sufficient port density to accommodate the cluster. These require enough ports to create a realistic spine-leaf topology providing ISL bandwidth above a 1:4 oversubscription ratio (preferably 1:1). | Although most enterprises have mature data network practices, consider building a dedicated data network for the Hadoop cluster. | At least two per rack. |
| Ethernet spine switches | Minimum 40 Gbps switches with sufficient port density to accommodate incoming ISL links and ensure required throughput over the spine (for inter-rack traffic). | Same considerations as for ToR switches. | Depends on the number of racks. |
