红帽全球峰会4.2.4.3. 存储开销
使用以下指南来估算 OpenShift Virtualization 环境的存储开销要求。
- 集群存储开销
Aggregated storage overhead per node ≈ 10 GiB在安装 OpenShift Virtualization 时，集群中每个节点的磁盘存储影响估计值为 10 GiB。
- 虚拟机存储开销
- 每个虚拟机的存储开销取决于虚拟机内的具体资源分配请求。该请求可能用于集群中其他位置托管的节点或存储资源的临时存储。OpenShift Virtualization 目前不会为正在运行的容器本身分配任何额外的临时存储。
- 例如
- 作为集群管理员，如果您计划托管集群中的 10 个虚拟机，每个虚拟机都有 1 GiB RAM 和 2 个 vCPU，集群中的内存影响为 11.68 GiB。集群中每个节点的磁盘存储影响估算为 10 GiB，托管虚拟机工作负载的 worker 节点的 CPU 影响为最小 2 个内核。
