- Practical Zima starting point
- ZimaBoard 2 1664 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 ONLYOFFICE Docs workload before selecting a server.
-
Official requirements
Choose the exact edition, stable release and supported container/runtime. Choose the current Community image topology from the official Docker documentation and include its required services.
-
Confirm your needs
Test a representative busy operation: Concurrent editing sessions, large spreadsheets and document conversions. Record peak resident memory, CPU, disk latency and completion time, including other containers.
-
Leave room to grow
Place active state on reliable persistent storage. Document-server configuration, certificates, logs and any persistent services; source documents also remain on the connected platform. 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. The current Docker requirements page lists a higher storage and swap baseline than parts of the repository README; follow the edition-specific requirements page.
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 ONLYOFFICE Docs 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 | 4 GB or more. | Official guidance keeps its original test, recommendation or example scope. |
| CPU guidance | Single core at 2 GHz or better; dual core or better recommended for production. | Core counts do not predict a fixed user, device or document capacity. |
| Storage planning | At least 40 GB free disk plus at least 4 GB swap in the current Community Docker requirements page. | Installation space is separate from retained content, working files and backups. |
| Service topology | Choose the current Community image topology from the official Docker documentation and include its required services. | Include every stateful companion service in the host budget. |
| Persistent state | Document-server configuration, certificates, logs and any persistent services; source documents also remain on the connected platform. | An image rebuild or container replacement is not a backup. |
| Deployment boundary | The current Docker requirements page lists a higher storage and swap baseline than parts of the repository README; follow the edition-specific requirements page. | Check the linked project instructions for the selected edition and release. |
When to upgrade your hardware
Use observed ONLYOFFICE Docs 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.Document-server configuration, certificates, logs and any persistent services; source documents also remain on the connected platform. 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.

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 ONLYOFFICE Docs RAM, CPU, storage, Docker, database and ZimaOS sizing questions.
How much RAM should I plan for ONLYOFFICE Docs?
4 GB or more. Include ZimaOS, the application and its companion services rather than reserving the entire machine for one container.
What drives the CPU requirement?
Single core at 2 GHz or better; dual core or better recommended for production. The workload to test is: Concurrent editing sessions, large spreadsheets and document conversions.
Which data must survive a container update?
Document-server configuration, certificates, logs and any persistent services; source documents also remain on the connected platform. Preserve a consistent database/file set and verify that your recovery procedure restores a working application.
What other services belong in the budget?
Choose the current Community image topology from the official Docker documentation and include its required services.
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?
The current Docker requirements page lists a higher storage and swap baseline than parts of the repository README; follow the edition-specific requirements page. 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 1664 is the editorial starting point for this modest deployment. Choose ZimaCube 2 Pro for measured memory/processing pressure or broader shared services; retained data determines storage expansion.
What sources informed this ONLYOFFICE Docs 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.
