x8i.64xlarge EKS max pods and allocatable memory — quick answers
- How many pods can a x8i.64xlarge run as a node with EKS, VPC CNI default (ENI limit)? Up to 1514; kubelet keeps 17009 MiB of memory and 710m CPU, leaving 4,079.39 GiB and 255.29 vCPU for pods.
- How many pods can a x8i.64xlarge run as a node with EKS, prefix delegation? Up to 250; kubelet keeps 3105 MiB of memory and 710m CPU, leaving 4,092.97 GiB and 255.29 vCPU for pods.
- How many 500m / 1 GiB pods fit? 510 per node after DaemonSets; 1 nodes for 10 replicas, about $20,447.48/month on demand.
What kubelet reserves on x8i.64xlarge
| 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 | 1514 | 710m | 16909 Mi + 100 Mi | 255.29 | 4,079.39 GiB | 99.6% |
