See documentation for the latest supported version 3 or the latest supported version 4.15.5. 配置巨页
节点必须预先分配在 OpenShift Container Platform 集群中使用的巨页。使用 Performance Addon Operator 在指定节点上分配巨页。
OpenShift Container Platform 提供了创建和分配巨页的方法。Performance Addon Operator 提供了一种更易于使用性能配置集的方法。
例如，在性能配置集的 hugepages pages 部分，您可以指定多个块的 size、count 以及可选的 node:
- 1
node是分配巨页的 NUMA 节点。如果省略了node，该页面将平均分布在所有 NUMA 节点中。
注意
等待显示更新已完成的相关机器配置池状态。
这些是分配巨页的唯一配置步骤。
验证
要验证配置，请查看节点上的
