p5.48xlarge EKS max pods and allocatable memory — quick answers
- How many pods can a p5.48xlarge run as a node with EKS, VPC CNI default (ENI limit)? Up to 100; kubelet keeps 1455 MiB of memory and 550m CPU, leaving 2,046.58 GiB and 191.45 vCPU for pods.
- How many pods can a p5.48xlarge run as a node with EKS, prefix delegation? Up to 250; kubelet keeps 3105 MiB of memory and 550m CPU, leaving 2,044.97 GiB and 191.45 vCPU for pods.
- How many 500m / 1 GiB pods fit? 97 per node after DaemonSets; 1 nodes for 10 replicas, about $40,179.20/month on demand.
What kubelet reserves on p5.48xlarge
| 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 | 100 | 550m | 1355 Mi + 100 Mi | 191.45 | 2,046.58 GiB | 99.9% |
| EKS, prefix delegation ENABLE_PREFIX_DELEGATION=true | 250 | 550m | 3005 Mi + 100 Mi | 191.45 | 2,044.97 GiB | 99.9% |
How these numbers are computed: reservation formulas. How many subnet IPs a p5.48xlarge 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 p5.48xlarge
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.
