x1e.8xlarge EKS max pods and allocatable memory — quick answers
- How many pods can a x1e.8xlarge run as a node with EKS, VPC CNI default (ENI limit)? Up to 58; kubelet keeps 993 MiB of memory and 150m CPU, leaving 975.03 GiB and 31.85 vCPU for pods.
- How many pods can a x1e.8xlarge run as a node with EKS, prefix delegation? Up to 250; kubelet keeps 3105 MiB of memory and 150m CPU, leaving 972.97 GiB and 31.85 vCPU for pods.
- How many 500m / 1 GiB pods fit? 55 per node after DaemonSets; 1 nodes for 10 replicas, about $4,870.56/month on demand.
What kubelet reserves on x1e.8xlarge
| 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 | 58 | 150m | 893 Mi + 100 Mi | 31.85 | 975.03 GiB | 99.9% |
| EKS, prefix delegation ENABLE_PREFIX_DELEGATION=true | 250 | 150m | 3005 Mi + 100 Mi | 31.85 | 972.97 GiB | 99.7% |
How these numbers are computed: reservation formulas. How many subnet IPs a x1e.8xlarge 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.8xlarge
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.
