Azure Stack 容量规划概述Overview of Azure Stack capacity planning

评估 Azure Stack 解决方案时,应考虑硬件配置选择,因为它直接影响到 Azure Stack 云的总体容量。When you're evaluating an Azure Stack solution, consider the hardware configuration choices that have a direct impact on the overall capacity of the Azure Stack cloud.

例如,需要就 CPU、内存密度、存储配置和总体解决方案规模或服务器数目进行选择。For example, you need to make choices regarding the CPU, memory density, storage configuration, and overall solution scale or number of servers. 不同于传统的虚拟化解决方案,简单地评估这些组件并不能很好地确定可用的容量。Unlike a traditional virtualization solution, the simple arithmetic of these components to determine usable capacity doesn't apply. 构建 Azure Stack 是为了在解决方案自身内部托管基础结构或管理组件。Azure Stack is built to host the infrastructure or management components within the solution itself. 另外,解决方案的某些容量保留用于支持复原;更新解决方案的软件时,必须将租户工作负荷的中断降到最低程度。Also, some of the solution's capacity is reserved to support resiliency, the updating of the solution's software in a way to minimize disruption of tenant workloads.

Azure Stack 解决方案是作为超融合群集构建的,包含计算和存储。An Azure Stack solution is built as a hyperconverged cluster of compute and storage. 可以通过超融合性来共享群集中的硬件容量(称为“缩放单元”)。 The convergence allows for the sharing of the hardware capacity in the cluster, referred to as a scale unit. 在 Azure Stack 中,缩放单元为资源提供可用性和可伸缩性。In Azure Stack, a scale unit provides the availability and scalability of resources. 缩放单元包含一组称为“主机”的 Azure Stack 服务器。 A scale unit consists of a set of Azure Stack servers, referred to as hosts. 基础结构软件托管在一组虚拟机 (VM) 中,与租户 VM 共享相同的物理服务器。The infrastructure software is hosted within a set of virtual machines (VMs), and shares the same physical servers as the tenant VMs. 然后所有 Azure Stack VM 可以通过缩放单元的 Windows Server 群集技术和独立的 Hyper-V 实例来管理。All Azure Stack VMs are then managed by the scale unit’s Windows Server clustering technologies and individual Hyper-V instances.

缩放单元简化了 Azure Stack 的获取和管理。The scale unit simplifies the acquisition and management Azure Stack. 缩放单元还可以跨 Azure Stack 移动和缩放所有服务(租户和体系结构)。The scale unit also allows for the movement and scalability of all services (tenant and infrastructure) across Azure Stack.
