How-To Interpret Available Capacity for Infiniband Instances in Crusoe Cloud

Last Updated: Oct 22, 2025

Introduction

This article explains how to check available capacity on Crusoe's InfiniBand (IB) networks using the Crusoe CLI and Console. It clarifies the meaning of the quantity field in the CLI output and provides guidance on retrieving InfiniBand capacity directly from the Console.

Pre-Requirements

• Access to Crusoe CLI.
• Access to Crusoe Console.

Understanding InfiniBand Capacity

When checking for available VM instances (slices) on a specific InfiniBand network, the Crusoe CLI provides a detailed output in JSON format. Understanding this output is key to automating capacity checks and planning deployments.

1. Check for available InfiniBand Networks

You can list the available InfiniBand networks and their capacity using the Crusoe CLI.

$ crusoe networking ib-networks list -f json

You can also get the details of a specific Infiniband Network using the following command: 

$ crusoe networking ib-networks get cff139e8-1a50-4bf7-af23-5075f0369616 -f json

Example Output:

[
	{
		"capacities": [
			{
				"quantity": 0,
				"slice_type": "h100-80gb-sxm-ib.8x"
			}
		],
		"id": "cff139e8-1a50-4bf7-af23-5075f0369616",
		"location": "us-southcentral1-a",
		"name": "us-southcentral1-a H100-80GB SXM IB Network 2"
	}
]

2. Interpreting the quantity field

The most important field for determining availability is quantity.

• slice_type: This field specifies the type of the VM instance, for example, h100-80gb-sxm-ib.8x.
• quantity: This field indicates the number of available slices for the corresponding slice_type that can be provisioned on that specific InfiniBand network.

A value of "quantity": 0 means that there are currently no available slices of that VM type on the specified IB network. You will not be able to create new instances of that slice_type on this network until capacity becomes available.

Alternative Method: Crusoe Cloud Console

You can also visually check for available GPU capacity across different InfiniBand networks directly in the Crusoe Cloud Console.

1. Navigate to the InfiniBand Networking section in the Crusoe Cloud Console.
2. This page provides a summary of all available InfiniBand networks and the number of available GPUs in each. The column Capacity indicates how many GPUs are available, and is equivalent to the "quantity" field in the CLI output.
