Storage and Partition Details

Minimum disk space requirement is 500 GB. Only locally mounted SSD storage is supported - NAS and network-attached storage are not supported. SWAP must be disabled.

Performance baseline (minimum):

  • IOPS: ≥ 4,500 sustained

  • Throughput: ≥ 250 MB/s sustained

  • Latency: <1 ms typical. NAS introduces bursty throttling and is unsuitable.

Note: For optimal performance, use NVMe SSDs. Alternatively, enterprise-grade locally mounted SSDs are acceptable.
Partition guidance:

  • / (root) - at least 20 GB, minimum 32M inodes

  • /var - at least 20 GB

  • /var/lib/rancher - at least 500 GB (or at least 80% of total allocated disk)

  • /tmp - at least 75 GB.

Note: If neither /var, /var/lib/rancher, nor /tmp is assigned to a dedicated partition, assign the full 500 GB to /root. If /var is assigned but /var/lib/rancher is not, assign 500 GB to /var. If /var/lib/rancher is assigned but /var is not, assign 500 GB to /var/lib/rancher.
