1

NovaReservedHugePages：从带有 NovaReservedHugePages 参数的巨页池中分配内存（以 MB 为单位）。它与 OvsDpdkSocketMemory 参数的值总量相同。

2

NovaReservedHostMemory：将内存（以 MB 为单位）用于带有 NovaReservedHostMemory 参数的主机上的任务。使用以下指南计算您必须保留的内存量：

每个 OSD 5 GB。
每个虚拟机的 0.5 GB 开销.
4GB 用于常规主机处理。确保您分配足够的内存，以防止通过跨 NUMA OSD 操作导致潜在的性能下降。

3

NovaVcpuPinSet：使用 NovaVcpuPinSet 参数列出 OvsPmdCoreList 中没有找到的 CPU、OvsDpdkCoreList 或 Ceph_osd_docker_cpuset_cpus。CPU 必须与 DPDK NIC 位于同一个 NUMA 节点。
