Kolibri hardware requirements at a glance
Kolibri hosts learning content and learner progress. Channel size, simultaneous playback and the local network drive practical sizing.
- RAM
- 1 GB recommended on Linux; 2 GB or more on Windows in upstream server guidance.
- CPU
- Upstream recommends an approximately 1 GHz Intel-class CPU; test actual concurrent playback.
- Storage
- Determined by imported content channels and learner data; no fixed channel-capacity figure applies.
- Required services
- The maintained Kolibri server runtime and channel-import process; client video decoding is a client-side requirement.
- Main sizing variable
- Channel imports, simultaneous video delivery and learner-progress writes.
- Practical Zima starting point
- ZimaBoard 2 832 with SSD-backed active state is an editorial starting point for modest use. Include the OS and all companion services; it is not a measured capacity guarantee.
From official requirements to the right setup
Plan the complete Kolibri workload before selecting a server.
-
Official requirements
Choose the exact edition, stable release and supported container/runtime. The maintained Kolibri server runtime and channel-import process; client video decoding is a client-side requirement.
-
Confirm your needs
Test a representative busy operation: Channel imports, simultaneous video delivery and learner-progress writes. Record peak resident memory, CPU, disk latency and completion time, including other containers.
-
Leave room to grow
Place active state on reliable persistent storage. Kolibri data directory, learner database, imported content channels and backups. Budget working space for an upgrade or import and test recovery before relying on the deployment.
-
Run it on ZimaOS
On ZimaOS, use a compatible amd64 container through Custom Install and reproduce all required services, volume mappings and device access. A server that stores lessons does not make old clients decode every video format; test playback on actual classroom devices.
Check every playback client
- Exact edition and stable release
- Compatible amd64 image/runtime
- All required companion services
- Realistic peak activity
- Persistent data and file ownership
- Free host ports and reachable URLs
- Working space and backup retention
- Successful database/file restore
Official minimum requirements
Reviewed October 30, 2026 against the linked upstream deployment documentation. Numerical values retain their stated minimum, recommendation or example scope; select release-compatible instructions before installation.
Use the requirements and scope above as a starting point, then validate Kolibri under its real workload. Application examples, build-time settings and per-container limits are not interchangeable with a whole-server minimum.
| Requirement | Official minimum | What this supports |
|---|---|---|
| RAM guidance | 1 GB recommended on Linux; 2 GB or more on Windows in upstream server guidance. | Official guidance keeps its original test, recommendation or example scope. |
| CPU guidance | Upstream recommends an approximately 1 GHz Intel-class CPU; test actual concurrent playback. | Core counts do not predict a fixed user, device or document capacity. |
| Storage planning | Determined by imported content channels and learner data; no fixed channel-capacity figure applies. | Installation space is separate from retained content, working files and backups. |
| Service topology | The maintained Kolibri server runtime and channel-import process; client video decoding is a client-side requirement. | Include every stateful companion service in the host budget. |
| Persistent state | Kolibri data directory, learner database, imported content channels and backups. | An image rebuild or container replacement is not a backup. |
| Deployment boundary | A server that stores lessons does not make old clients decode every video format; test playback on actual classroom devices. | Check the linked project instructions for the selected edition and release. |
When to upgrade your hardware
Use observed Kolibri 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.Kolibri data directory, learner database, imported content channels and 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.
★★★★★
Great innovation for mini server!
It is very useful and makes a powerful mini server for many purposes, including university and college students in engineering and electronics. Thank you so much for making this server.

Avaliação ZimaBoard 2
Construí um servidor de uso pessoal. O desempenho está muito bom e funciona perfeitamente onde quer que eu esteja. A surpresa é não dependermos de grandes estruturas para termos nosso próprio servidor de dados. Como iniciante, estou gostando bastante do ZimaOS, pois ele é simples e eficiente.
Frequently asked questions
Answers to Kolibri RAM, CPU, storage, Docker, database and ZimaOS sizing questions.
How much RAM should I plan for Kolibri?
1 GB recommended on Linux; 2 GB or more on Windows in upstream server guidance. Include ZimaOS, the application and its companion services rather than reserving the entire machine for one container.
What drives the CPU requirement?
Upstream recommends an approximately 1 GHz Intel-class CPU; test actual concurrent playback. The workload to test is: Channel imports, simultaneous video delivery and learner-progress writes.
Which data must survive a container update?
Kolibri data directory, learner database, imported content channels and backups. Preserve a consistent database/file set and verify that your recovery procedure restores a working application.
What other services belong in the budget?
The maintained Kolibri server runtime and channel-import process; client video decoding is a client-side requirement.
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?
Use an amd64 container and the current upstream service topology through Custom Install when a suitable maintained image is available. Container availability alone is not a compatibility certification.
What should I check before upgrading hardware?
A server that stores lessons does not make old clients decode every video format; test playback on actual classroom devices. Compare CPU saturation, memory pressure, disk latency and external-service waits during the same reproducible operation.
Which Zima device is a practical starting point?
ZimaBoard 2 832 is the editorial starting point for this modest deployment. Choose ZimaBoard 2 1664 for measured memory/processing pressure or broader shared services; retained data determines storage expansion.
What sources informed this Kolibri hardware guide?
This guide was reviewed against the linked project deployment documentation on October 30, 2026. Zima device choices are editorial workload guidance, separate from upstream requirements and measured performance.
