Limits

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_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

Reference: https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-hyperpod-eks-prerequisites.html

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.
