inf1.24xlarge EKS max pods and allocatable memory — quick answers
- How many pods can a inf1.24xlarge run as a node with EKS, VPC CNI default (ENI limit)? Up to 321; kubelet keeps 3886 MiB of memory and 310m CPU, leaving 188.21 GiB and 95.69 vCPU for pods.
- How many pods can a inf1.24xlarge run as a node with EKS, prefix delegation? Up to 250; kubelet keeps 3105 MiB of memory and 310m CPU, leaving 188.97 GiB and 95.69 vCPU for pods.
- How many 500m / 1 GiB pods fit? 187 per node after DaemonSets; 1 nodes for 10 replicas, about $3,446.33/month on demand.
What kubelet reserves on inf1.24xlarge
| Setup | Max pods | kube-reserved CPU | Memory reserved + eviction | Allocatable CPU | Allocatable memory | Memory usable |
|---|---|---|---|---|---|---|
| EKS, VPC CNI default (ENI limit) secondary IPs per ENI | 321 | 310m | 3786 Mi + 100 Mi | 95.69 | 188.21 GiB | 98.0% |
| EKS, prefix delegation ENABLE_PREFIX_DELEGATION=true | 250 | 310m | 3005 Mi + 100 Mi | 95.69 | 188.97 GiB | 98.4% |
How these numbers are computed: reservation formulas. How many subnet IPs a inf1.24xlarge takes with the VPC CNI: EKS max pods and IP calculator. Check a live node with kubectl describe node → Allocatable.
