Current Cluster Information
As of September 2025, the following table summarizes the DSI cluster resources. Some resources are reserved for specific initiatives or grants.
Total Cluster Resources
| Resource Type | Number of Units |
|---|---|
| Number of Nodes | 29 |
| Total Cores | 2,720 |
| Total Storage | 1.5 PB |
| GPUs | 32 NVIDIA A40 48GB 60 NVIDIA A100 80GB 12 NVIDIA L40S 48GB 16 NVIDIA H100 80GB 20 NVIDIA H200 140GB Total: 140 |
Cluster Networking and Topology
The cluster is organized into a series of nodes and storage servers. Storage servers have a mix of different drives and types.
Note that not all nodes are available on all SLURM partitions and queues.
The cluster has a 1Gb/s line to the internet (with a potential upgrade date of July 2026).
The network between nodes and storage servers runs at 10 Gbps.
Space Availability and Server Room
The server room is power-constrained. While each rack can hold 8 nodes physically, power typically supports 4 nodes per rack. With 8 open racks, we anticipate capacity for approximately 24 additional nodes (24 + 29 = 53 total), hardware-dependent.
