Requirements¤
This page lists software and hardware requirements for eccenca Corporate Memory deployments. For a general overview of a deployment setup please refer to the System Architecture.
Minimal Setup¤
A minimal single-node deployment for testing/evaluation purposes means:
- no memory consuming linking and transformation workflows,
- nearly no concurrent users.
Depending on how much RAM is dedicated to the triple store, Knowledge Graphs up to several million triples can be built and served.
- Operating System / Hardware
- Bare metal server or VM with Debian based linux OS (see Installation for details)
- 16 GB RAM
- 100 GB free disk space (10 GB for docker images + data + logs over time)
- docker and docker compose (we deliver an orchestration including all needed components)
For an example of a single-node installation refer to the following scenarios:
- Scenario: Local Installation
- Scenario: RedHat Enterprise Linux 7
- Scenario: Single Node Cloud Installation
Typical Setup¤
In a typical deployment all components are installed on separate VMs (nodes). Therefore, six separate VMs are required.
The following numbers are based on existing customer deployments running Knowledge Graphs up to 300 million triples with 40 concurrent users.
| Component | CPU | Memory |
|---|---|---|
| eccenca Explore | >= 4 cores1 | >= 8 GB RAM |
| eccenca Build (DataIntegration) | >= 4 cores2 | >= 8 GB RAM2 |
| Triple / Quad Store | >= 4 cores1 | >= 8 GB RAM3 |
| Keycloak incl. PostgreSQL4 | 2 cores | >= 4 GB RAM |
| Proxy Server4 | >= 2 cores1 | >= 2 GB RAM |
