CloudStack hardware requirements at a glance
Cloud computing software for creating, managing, and deploying infrastructure cloud services. A scheduler is smaller than the jobs it starts. Include worker processes, browser/model integrations and external API limits; bound concurrency before adding more workers.
- RAM
- 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.
- CPU
- No fixed numerical whole-host figure is inferred here; follow the selected release and deployment requirements. Measure CPU use during realistic activity.
- Storage
- Persist workflow definitions, credentials, job metadata, logs and retained input/output artifacts.
- Required services
- Use the supported upstream runtime and complete service topology for the selected release. The repository references MariaDB / MySQL. These may be optional integrations or alternatives; install only services required by your chosen deployment.
- Main sizing variable
- parallel jobs, task duration, browser sessions and separately executed scripts
- Practical Zima starting point
- Conditional lab, data-storage or supporting-service hardware only; a complete production deployment requires a separately verified host meeting the upstream requirements. A scheduler is smaller than the jobs it starts. Include worker processes, browser/model integrations and external API limits; bound concurrency before adding more workers.
From official requirements to the right setup
Plan the complete CloudStack workload before selecting a server.
-
Official requirements
Choose the exact edition, stable release and supported container/runtime. Use the supported upstream runtime and complete service topology for the selected release. The repository references MariaDB / MySQL. These may be optional integrations or alternatives; install only services required by your chosen deployment.
-
Confirm your needs
Test a representative busy operation: parallel jobs, task duration, browser sessions and separately executed scripts 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 workflow definitions, credentials, job metadata, logs and retained input/output artifacts. 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. A scheduler is smaller than the jobs it starts. Include worker processes, browser/model integrations and external API limits; bound concurrency before adding more workers.

| Requirement | Official minimum | What this supports |
|---|---|---|
| RAM guidance | 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. | Official guidance keeps its original test, recommendation or example scope. |
| CPU guidance | No fixed numerical whole-host figure is inferred here; follow the selected release and deployment requirements. Measure CPU use during realistic activity. | Core counts do not predict a fixed user, device or document capacity. |
| Storage planning | Persist workflow definitions, credentials, job metadata, logs and retained input/output artifacts. | Installation space is separate from retained content, working files and backups. |
| Service topology | Use the supported upstream runtime and complete service topology for the selected release. The repository references MariaDB / MySQL. These may be optional integrations or alternatives; install only services required by your chosen deployment. | Include every stateful companion service in the host budget. |
| Persistent state | Persist workflow definitions, credentials, job metadata, logs and retained input/output artifacts. | An image rebuild or container replacement is not a backup. |
| Deployment boundary | A scheduler is smaller than the jobs it starts. Include worker processes, browser/model integrations and external API limits; bound concurrency before adding more workers. | Check the linked project instructions for the selected edition and release. |
When to upgrade your hardware
Use observed CloudStack 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 workflow definitions, credentials, job metadata, logs and retained input/output artifacts. 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.
