Each node weighs approximately 100 kg.
CPU-only nodes
6 CPU-only nodes are available, each with 1 TB RAM, for memory-intensive workloads that do not require GPU acceleration.
Storage
The system provides approximately 4.3 PB of usable all-NVMe capacity, combining:
- 48 × 30 TB TLC drives
- 48 × 122 TB QLC drives
