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 Anki Sync Server 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 | No universal numerical whole-host baseline is specified in the reviewed deployment source. Size the full stack during the busy operation described below. | Official guidance keeps its original test, recommendation or example scope. |
| CPU guidance | No universal numerical whole-host baseline is specified in the reviewed deployment source. Measure CPU use during realistic activity. | Core counts do not predict a fixed user, device or document capacity. |
| Storage planning | The directory selected by SYNC_BASE, collection/media state and configured account credentials. | Installation space is separate from retained content, working files and backups. |
| Service topology | Official packaged/Python/Rust server routes; the manual links a user-contributed Dockerfile rather than promising an official container image. | Include every stateful companion service in the host budget. |
| Persistent state | The directory selected by SYNC_BASE, collection/media state and configured account credentials. | An image rebuild or container replacement is not a backup. |
| Deployment boundary | Client/server protocol versions must stay compatible; keep the server directory separate from a desktop client's ordinary Anki folder. | Check the linked project instructions for the selected edition and release. |
When to upgrade your hardware
Use observed Anki Sync Server 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.The directory selected by SYNC_BASE, collection/media state and configured account credentials. 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.
★★★★★
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 Anki Sync Server RAM, CPU, storage, Docker, database and ZimaOS sizing questions.
How much RAM should I plan for Anki Sync Server?
No universal numerical whole-host baseline is specified in the reviewed deployment source. 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 universal numerical whole-host baseline is specified in the reviewed deployment source. Measure CPU use during realistic activity. The workload to test is: First full sync, many media files and simultaneous client updates.
Which data must survive a container update?
The directory selected by SYNC_BASE, collection/media state and configured account credentials. Preserve a consistent database/file set and verify that your recovery procedure restores a working application.
What other services belong in the budget?
Official packaged/Python/Rust server routes; the manual links a user-contributed Dockerfile rather than promising an official container image.
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?
Client/server protocol versions must stay compatible; keep the server directory separate from a desktop client's ordinary Anki folder. 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 Anki Sync Server 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.
