Basic Hardware Requirement
This chapter provides the recommended basic configuration to run the application.
POS Server is a central application. The following configuration applies to one HW node running one JVM server (running ECON, SDC, MWB, LPS, POS Server, POS Service).
Each server contains several JVM instances. Their number can increase the performance (scaling).
See the Master Sizing Guide which contains the following:
- Explained principle of horizontal scaling - Master Sizing Guide: 2.3 Cluster Sizing
- Information about storage capacity - Master Sizing Guide: 5 Storage
- The recommended configuration for the application - Master Sizing Guide: 4 Process Configuration
- Global configuration for DB server - Master Sizing Guide: 7.3 Sizing Calculation for Database
Application
The configuration shown here is sufficient to run one JVM Server:
| CPU | RAM | JVM heap size | Dedicated space (meta space) |
|---|---|---|---|
| 2.13 GHz, 4 Cores | 12 GB | 6 GB | 2 GB |
The principle of horizontal scaling is explained in detail in the Master Sizing Guide, chapter Cluster Sizing.
Storage
| Recommended storage capacity | |
|---|---|
| Local [GB] | Share [GB] |
| 80 | 1 |
The recommended configuration for the application and database along with detailed information on the storage capacity are included in Master Sizing Guide, chapter Storage.
