d3.2xlarge EKS max pods and allocatable memory — quick answers
- How many pods can a d3.2xlarge run as a node with EKS, VPC CNI default (ENI limit)? Up to 18; kubelet keeps 553 MiB of memory and 90m CPU, leaving 63.46 GiB and 7.91 vCPU for pods.
- How many pods can a d3.2xlarge run as a node with EKS, prefix delegation? Up to 110; kubelet keeps 1565 MiB of memory and 90m CPU, leaving 62.47 GiB and 7.91 vCPU for pods.
- How many 500m / 1 GiB pods fit? 15 per node after DaemonSets; 1 nodes for 10 replicas, about $729.27/month on demand.
What kubelet reserves on d3.2xlarge
| 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 | 18 | 90m | 453 Mi + 100 Mi | 7.91 | 63.46 GiB | 99.2% |
| EKS, prefix delegation ENABLE_PREFIX_DELEGATION=true | 110 | 90m | 1465 Mi + 100 Mi | 7.91 | 62.47 GiB | 97.6% |
How these numbers are computed: reservation formulas. How many subnet IPs a d3.2xlarge 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 d3.2xlarge
