# Limits
<a name="ds-limits"></a>

Spaces run as pods on HyperPod EKS nodes with attached EBS volumes. The number of Spaces that can be deployed per node is constrained by AWS infrastructure limits.

**EBS Volume Limits per Node**

Reference: [https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/volume\$1limits.html](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/volume_limits.html)

EC2 nodes have a maximum number of EBS volumes that can be attached. Since each Space typically uses one EBS volume, this limits how many Spaces with dedicated EBS storage can run on a single node.

**Maximum Pods per HyperPod Node**

Each HyperPod instance type supports a maximum number of pods based on available IP addresses from the VPC CNI plugin. Since each Space runs as a pod, this directly caps the number of Spaces per node.

**Impact**

The effective limit for Spaces per node is whichever constraint is reached first.
