|
|
- Support for Replication and Erasure Coding
|
|
- Dynamic addition and removal of nodes and OSDs
|
|
- User-friendly interface with modern design
|
|
- Dark/Light Mode support
|
|
- Export/Import of configurations
|
|
- PDF report generation
|
|
- Responsive design for all devices
|
|
- Fault tolerance analysis for nodes and OSDs
|
|
|
|
## Installation
|
|
|
|
1. Clone repository:
|
|
```
|
|
git clone <repository-url>
|
|
cd ceph-calculator
|
|
```
|
|
|
|
2. Install Node.js dependencies:
|
|
```
|
|
npm install
|
|
```
|

|
|
|
5. Open in a browser: `http://localhost:5000`
|
|
|
|
## Usage
|
|
|
|
1. Select the replication type: Replication or Erasure Coding
|
|
2. Enter the corresponding parameters:
|
|
- For Replication: Number of replicas and min_size
|
|
- For Erasure Coding: k (data chunks) and m (coding chunks)
|
|
3. Add nodes and configure their OSDs with appropriate storage sizes
|
|
4. Select the desired storage unit (GB/TB)
|
|
5. Click on "Calculate Capacity" to see the result
|
|
6. Optional: Export the configuration or generate a PDF report
|
|
|
|
