Large numbers of active widgets and health checks add network and Node processing, though the app remains lightweight.
Large homelab dashboards.Dashyのハードウェア要件：RAM、CPU、ディスク＆Docker
Dashyのハードウェアを、公式のシングルコア、256 MB RAM、約250 MBのディスク容量という推奨値と、ZimaOSのワンクリックデプロイに適した実用的なサイジングに基づいて計画する。
Dashy requirements at a glance
Dashy's current deployment documentation provides clear lightweight system-resource guidance for the Node server and Docker image.
- CPU
- Official requirement: any single core on x86-64 or ARM.
- RAM
- The Node server idles around 80–120 MB; 256 MB is described as comfortable and Dashy can work with less.
- Disk
- About 250 MB for the image, plus whatever your config, custom icons and other assets require.
- Architecture
- Current pre-built Docker images support amd64 and arm64; 32-bit armv7/armv6 are no longer supported by current images.
- GPU
- No GPU is required. Dashy is a lightweight dashboard/homepage application.
- Best Zima starting point
- ZimaBoard 2 832 is vastly above Dashy's requirements; choose larger Zima hardware only for the services Dashy links to.
From official requirements to the right setup
Dashy itself is lightweight, so size the server for the rest of your homelab and treat Dashy as a small frontend workload.
-
Official requirements
Use Dashy's published baseline: any single x86-64/ARM core, around 80–120 MB idle RAM, 256 MB comfortable, and about 250 MB image storage.
-
Confirm your needs
Persist /app/user-data because conf.yml and custom assets live there and should survive container upgrades.
-
Leave room to grow
Account for optional widgets, status checks and custom assets, but avoid sizing the host around Dashy when the linked services are far heavier.
-
Run it on ZimaOS
Install Dashy through the ZimaOS App Store, map persistent user-data, then size ZimaBoard/ZimaCube for the underlying media, AI, storage and automation services.
Check every playback client
- Number of dashboard pages
- Widgets/status checks
- Custom icons/assets
- Persistent user-data
- Authentication/SSO use
- Reverse proxy/HTTPS
- Linked homelab services
- Other ZimaOS apps
Official minimum requirements
Dashy's current deployment documentation publishes direct CPU, RAM and disk guidance.
Dashy is one of the lightest apps in this hardware directory. The 256 MB RAM and ~250 MB disk figures describe the app itself; Zima hardware selection should usually be driven by the services behind the dashboard.
| Requirement | Official minimum | What this supports |
|---|---|---|
| CPU | Any single core | x86-64 or ARM. |
| RAM idle | Approximately 80–120 MB | Current Node server idle range. |
| RAM comfortable | 256 MB | Dashy documentation says it works in less. |
| Disk | Approximately 250 MB | For the image, plus config/icons/custom assets. |
| Docker architectures | amd64 and arm64 | Current images do not support armv7/armv6. |
| Bare-metal runtime | Node.js 20+ and Yarn | Only needed when not using the pre-built container. |
When to upgrade your hardware
Dashy itself rarely causes a hardware upgrade; the linked services or unusually heavy dashboard customization usually do.
Widgets and status checks become unusually numerous
Custom assets expand
The host runs many heavy applications
Icons, images and custom files increase persistent storage beyond the small base image size.
Highly customized dashboards.Media servers, AI, databases and automation services dominate CPU/RAM long before Dashy itself does.
All-in-one ZimaOS systems.Plan hardware growth with confidence
Scale the services behind Dashy, not Dashy itself.
Keep Dashy on the smallest Zima host
Its official resource needs are far below even ZimaBoard 2 832 capacity.
ZimaBoard 2 832 is already ample.Persist configuration on reliable storage
Protect conf.yml and custom user-data even though the total storage footprint is small.
Any reliable Zima storage is sufficient for Dashy itself.Add RAM for the linked homelab apps
If the server grows, extra memory benefits databases, automation and media services rather than the dashboard.
ZimaBoard 2 1664 provides 16 GB whole-host headroom.Choose ZimaCube for broader storage/server needs
A larger NAS is justified by media, backups and application consolidation, not Dashy alone.
ZimaCube 2 Standard or Pro depending on the wider workload.Can it run on ZimaOS?
Dashy is currently highlighted by ZimaOS as a one-click App Store application in the Automation and Operations category.
Install Dashy from the ZimaOS App Store
Use the ZimaOS one-click Dashy listing, then persist /app/user-data for conf.yml and custom assets.
Open Dashy in the ZimaOS App Store ↗Use Dashy's official Docker deployment model
The current documentation recommends Docker for self-hosting and publishes a simple lissy93/dashy image workflow.
Review Dashy deployment ↗Keep Dashy sizing separate from homelab sizing
ZimaOS positions Dashy as a homelab homepage; the services it links to should drive the real hardware decision.
Review ZimaOS App Store overview ↗Choose Zima hardware for Dashy
Every current ZimaBoard 2 configuration is massively over the app's own CPU/RAM requirements, so choose hardware for the rest of the homelab.
Is Dashy the main workload or just the homepage for a larger server?
Dashy plus lightweight utilities
Use ZimaBoard 2 832; Dashy consumes only a small fraction of its resources.
- Best starting pointZimaBoard 2 832
Dashy fronts a larger homelab
Choose hardware for the linked apps, storage and network requirements rather than Dashy.
- More app headroomZimaBoard 2 1664
- Broader NAS platformZimaCube 2 Standard
These recommendations apply to Dashy itself; linked services can have completely different requirements.
| Zima hardware | Best for | Example workload | Core configuration | Recommended boundary | Next step |
|---|---|---|---|---|---|
| ZimaBoard 2 832 | Dashy plus lightweight homelab utilities. | Dashboard, status checks, widgets, reverse proxy and small companion services. |

Dashy uses only a small fraction of this hardware; sizing should focus on the other apps. | Get Now |
| ZimaBoard 2 1664 | Dashy as the homepage for a larger self-hosted stack. | Many Docker apps, databases, automation and monitoring services. |

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.
