Storage requirements - Poolside

Partitioning overview

This page shows recommended partition sizing for single-node Poolside on-premises model deployments running RKE2 and explains how model checkpoints affect storage requirements. The checkpoint estimates cover these model artifacts:

Model Checkpoint size (GB)

laguna_xs_fp8_fp8kv_re_06_2026 33

Partition recommendations for STIG-hardened hosts

For STIG-hardened Linux nodes, Poolside recommends the following partition layout and sizing as a minimum for the listed models:

Mount Size Filesystem Mount options Purpose
/boot/efi 600M fat32 umask=0077 UEFI system partition
/boot 1G xfs nodev,nosuid Kernel, initramfs
/ 50G xfs defaults OS root
/tmp 2G xfs nodev,nosuid,noexec Temporary files
/var 5G xfs nodev,nosuid Cache, spool, backups
/var/tmp 10G xfs nodev,nosuid,noexec Temporary files
/var/log 50G xfs nodev,nosuid,noexec System + audit logs
/var/lib 400G xfs nodev,nosuid kubelet, rancher, containers
/home 50G xfs nodev,nosuid Terraform working directories
/opt/poolside 350G xfs nodev,nosuid Model artifact storage
swap 4G swap none Swap space

The total recommended disk space for the listed model artifacts is 1 TB.

Dedicated /opt/poolside partition for model artifacts

STIG controls recommend dedicated partitions to prevent system partitions from filling up and causing denial of service. Poolside recommends placing model artifact storage on a dedicated /opt/poolside partition rather than the root filesystem. Without separation, model artifact growth can render the OS unusable.

Inference storage impact

When you run inference workloads, each inference pod loads model checkpoints from SeaweedFS into a storage-backed emptyDir volume under /var/lib/kubelet. This means you store at least two copies of the model checkpoint on disk: one copy in SeaweedFS and one copy in the emptyDir volume for each running pod. Each inference workload consumes disk space equal to its model checkpoint size:

Model Checkpoint size (GB) emptyDir consumption (GB) Total disk usage (GB)
laguna_m_fp8_fp8kv_re_06_2026 214 214 428
laguna_xs_fp8_fp8kv_re_06_2026 33 33 66

Plan for sufficient free space in /var/lib to accommodate your largest model’s checkpoint size for each running inference pod.

Scaling prioritization guidance

If you need to scale storage, allocate additional space in this priority order:

  1. /var/lib: Scales per model deployed in-cluster
  2. /opt/poolside: Scales with model checkpoints
  3. /home: Scales with Terraform files. The Poolside Terraform bundle packages container upgrade images.

Core OS partitions (/, /boot, /tmp, /var, /var/tmp, /var/log) can remain fixed regardless of total disk size.
