From official requirements to the right setup
Plan the complete Rook workload before selecting a server.

Official requirements
Choose the exact edition, stable release and supported container/runtime. Follow the supported upstream runtime and complete Rook deployment topology for the selected release. Rook is a Kubernetes storage operator, not the storage cluster itself. Include the selected backend daemons, devices, node resources and recovery topology in addition to operator pods.
-
Confirm your needs
Test a representative busy operation: metadata operations, active cached data, client concurrency, replication and recovery traffic Record peak resident memory, CPU, disk latency and completion time, including other containers.
-
Leave room to grow
Place active state on reliable persistent storage. Persist cluster metadata, volume/object contents, journals, placement configuration, snapshots and independent backups. Budget working space for an upgrade or import and test recovery before relying on the deployment.

Run it on ZimaOS
Follow the supported upstream runtime, operating system and complete service topology for the selected release. On ZimaOS, consider Custom Install only when a maintained compatible amd64 image and every required host capability have been verified. Otherwise use a separately supported Linux environment; this guide does not certify an unverified container deployment. Rook is a Kubernetes storage operator, not the storage cluster itself.

When to upgrade your hardware
Use observed Rook workload pressure to decide when an upgrade is warranted.
Busy operations exceed the available window
The complete stack runs short of memory
Persistent data approaches available capacity
Inspect the application and each required service for OOM events, sustained swap or growing queues. Reduce unnecessary concurrency before adding capacity.
Shared hosts and background work.Persist cluster metadata, volume/object contents, journals, placement configuration, snapshots and independent backups. Track primary state and backup retention separately.
Long-lived installations and growing collections.Plan hardware growth with confidence
Address storage, memory, compute and deployment limits separately.
Use suitable active storage
Put latency-sensitive application/database state on durable local SSD storage and keep recoverable copies.
SATA or PCIe SSD according to measured data growth.Add memory for the complete stack
Choose a higher-RAM host when peak application and companion-service usage leaves inadequate OS headroom.
ZimaBoard 2 832 or ZimaBoard 2 1664 according to the measured constraint.Separate capacity from compute
A multi-drive system helps when retained content and backup storage are the problem; it is not automatically a faster application.

Zima Blade Little yet Powerful
Maybe I am not digital natives but I live with PCs since 12 years old in 1984 when IBM PC clone come to my home. Many years have passed and many operating system I've tried. For me Zima blade and CasaOS was a quantum leap for home PC enthusiast and server lab machine to make me stay curious and relevant for this era.

Very good!!
I use ZimaCube Pro as 5th Proxmox cluster node. It runs several VMs and containers, including a VM with GPU passthrough to run a self-hosted LLM. A specific LXC container runs a Samba server for NAS capabilities using four of six RAID 6 SATA HDDs with ZFS.

Frequently asked questions
Answers to Rook RAM, CPU, storage, Docker, database and ZimaOS sizing questions.
How much RAM should I plan for Rook?
No fixed numerical whole-host figure is inferred here; follow the selected release and deployment requirements. Size the full stack during the busy operation described below. Include ZimaOS, the application and its companion services rather than reserving the entire machine for one container.
What drives the CPU requirement?
No fixed numerical whole-host figure is inferred here; follow the selected release and deployment requirements. Measure CPU use during realistic activity. The workload to test is: metadata operations, active cached data, client concurrency, replication and recovery traffic
Which data must survive a container update?
Persist cluster metadata, volume/object contents, journals, placement configuration, snapshots and independent backups. Preserve a consistent database/file set and verify that your recovery procedure restores a working application.
What other services belong in the budget?
Follow the supported upstream runtime and complete Rook deployment topology for the selected release. Rook is a Kubernetes storage operator, not the storage cluster itself. Include the selected backend daemons, devices, node resources and recovery topology in addition to operator pods.
Does this workload need a dedicated GPU?
A dedicated GPU is not assumed for the core workflow described here. Optional AI, acceleration or media-processing integrations must be evaluated separately against the selected backend.
Can I deploy it on ZimaOS?
Follow the supported upstream runtime, operating system and complete service topology for the selected release. On ZimaOS, consider Custom Install only when a maintained compatible amd64 image and every required host capability have been verified. Otherwise use a separately supported Linux environment; this guide does not certify an unverified container deployment. Rook is a Kubernetes storage operator, not the storage cluster itself. Include the selected backend daemons, devices, node resources and recovery topology in addition to operator pods.
What should I check before upgrading hardware?
Rook is a Kubernetes storage operator, not the storage cluster itself. Include the selected backend daemons, devices, node resources and recovery topology in addition to operator pods. Measure the same representative operation before and after a configuration or hardware change.
Which Zima device is a practical starting point?
Conditional lab, data-storage or supporting-service hardware only; a complete production deployment requires a separately verified host meeting the upstream requirements. Rook is a Kubernetes storage operator, not the storage cluster itself. Include the selected backend daemons, devices, node resources and recovery topology in addition to operator pods.
What sources informed this Rook hardware guide?
This guide was reviewed against the linked project deployment documentation on November 11, 2026. Zima device choices are editorial workload guidance, separate from upstream requirements and measured performance.
