x1e.xlarge EKS max pods and allocatable memory — quick answers
- How many pods can a x1e.xlarge run as a node with EKS, VPC CNI default (ENI limit)? Up to 29; kubelet keeps 674 MiB of memory and 80m CPU, leaving 121.34 GiB and 3.92 vCPU for pods.
- How many pods can a x1e.xlarge run as a node with EKS, prefix delegation? Up to 110; kubelet keeps 1565 MiB of memory and 80m CPU, leaving 120.47 GiB and 3.92 vCPU for pods.
- How many 500m / 1 GiB pods fit? 7 per node after DaemonSets; 2 nodes for 10 replicas, about $1,217.64/month on demand.
What kubelet reserves on x1e.xlarge
| 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 | 29 | 80m | 574 Mi + 100 Mi | 3.92 | 121.34 GiB | 99.5% |
| EKS, prefix delegation ENABLE_PREFIX_DELEGATION=true | 110 | 80m | 1465 Mi + 100 Mi | 3.92 | 120.47 GiB | 98.7% |
How these numbers are computed: reservation formulas. How many subnet IPs a x1e.xlarge takes with the VPC CNI: EKS max pods and IP calculator. Check a live node with kubectl describe node → Allocatable.
How many pods fit on one x1e.xlarge
Assumes DaemonSets (CNI, kube-proxy, log and metrics agents) request 200m CPU, 300 Mi and 3 pods per node. Try your own numbers in the node calculator.
