JIRA hardware requirements at a glance
Size JIRA from verified upstream requirements first, then add headroom for workload and persistent data.
- RAM
- Small-instance sizing guidance starts around 8 GB system memory
- CPU
- No single universal core minimum in the sizing guide
- Storage
- Small sizing guidance: roughly 10–50 GB total; attachments often dominate
- Java
- Current Jira Data Center 11.3 requires Java 21 runtime level
- Database
- Current Jira 11.3 supports PostgreSQL 16/17 among supported databases
- Best Zima starting point
- ZimaCube 2 Pro for a lab/small single-node evaluation; not a substitute for enterprise Data Center architecture
From official requirements to the right setup
Start with current upstream facts for JIRA, then size the real workload rather than copying generic container or app-store labels.

Official minimum requirements
Atlassian publishes sizing guidance rather than one universal hardware minimum. Jira Server is end-of-support; current supported self-managed deployments are Jira Data Center.
For small historical/single-node sizing, Atlassian's guide starts at about 8 GB system RAM, >1 GB JVM heap, and roughly 10–50 GB disk, but current production Jira Data Center must also follow version-specific supported-platform and architecture guidance.
| Requirement | Official minimum | What this supports |
|---|---|---|
| Jira Server support ended February 15, 2024 | Current self-managed product is Jira Data Center. | |
| About 8 GB for small profile | Higher profiles exceed 8/16 GB. | |
| >1 GB small profile | Larger profiles require more. | |
| About 10–50 GB small profile | Attachments and indexes can be much larger. | |
| Use fastest disks possible / SSD | Index I/O matters. | |
| Java 21 runtime level | Current supported platform. | |
| Not required | No GPU workload. |
When to upgrade your hardware
Issue/user growth
Index/database pressure
HA/enterprise requirement
Plan hardware growth with confidence
Fast index storage
Keep Jira home/index on fast SSD/NVMe.
SSD/NVMeMore RAM
Jira and JVM/database caches benefit from substantial headroom.
16 GB+Attachment capacity
Expand storage for attachments and backups.
ZimaCube storageEnterprise architecture
Use supported Data Center clustering/database infrastructure at scale.
Multi-node infrastructureCan it run on ZimaOS?
Custom install / VM only for lab or evaluation
No specific public official ZimaOS per-app page was verified, and modern Jira Data Center is not a lightweight home-server app.
Custom install JIRA in the ZimaOS app ↗Use current Jira Data Center supported-platform guidance
Current Jira 11.3 uses Java 21 and version-specific supported databases.
Open Jira supported platforms ↗Do not deploy unsupported Jira Server as if it were current
Server support ended February 15, 2024.
Open Jira Server sizing/EOL context ↗Zima hardware for JIRA
Jira is a heavyweight Java/database/indexing workload. A single Zima machine is suitable only for lab/small evaluation scenarios, not as a blanket enterprise Data Center recommendation.
Choose by workload
Use the strongest practical Zima option with SSD-backed indexes and an external supported DB.
Follow Jira Data Center architecture and cluster sizing rather than home-server rules.
Current self-managed Jira is Data Center; the JSON does not treat end-of-support Jira Server as a current supported product.
| Zima hardware | Best for | Example workload | Core configuration | Recommended boundary | Next step |
|---|---|---|---|---|---|
| ZimaCube 2 Pro | CPU-heavy, database-heavy, and higher-concurrency services | Jira, larger helpdesk/collaboration stacks, and heavier indexing |

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
Is Jira Server still supported?
No. Atlassian Server product support ended on February 15, 2024.
What is the current self-managed Jira product?
Jira Data Center.
How much RAM does the small sizing profile use?
Atlassian's sizing guide starts around 8 GB system memory for a small profile.
Which Java version does current Jira 11.3 use?
Java 21 runtime level.
What storage matters most?
Indexes need very fast storage; attachments and backups often dominate capacity.
Can ZimaCube 2 Pro run Jira?
It can support a lab or small evaluation, but it should not be treated as a universal production Data Center platform.
Does Jira need a GPU?
No.
When should Jira move beyond one host?
When production HA, larger scale, or enterprise performance requirements apply.
