什么是 Azure 上的 SAP HANA(大型实例)?What is SAP HANA on Azure (Large Instances)?

Azure 上的 SAP HANA(大型实例)是一种针对 Azure 的独特解决方案。SAP HANA on Azure (Large Instances) is a unique solution to Azure. 除了提供虚拟机用于部署和运行 SAP HANA 以外,Azure 还可让你在专用的逻辑服务器上运行和部署 SAP HANA。In addition to providing virtual machines for deploying and running SAP HANA, Azure offers you the possibility to run and deploy SAP HANA on bare-metal servers that are dedicated to you. Azure 上的 SAP HANA(大型实例)解决方案在分配的非共享主机/服务器裸机硬件上进行构建。The SAP HANA on Azure (Large Instances) solution builds on non-shared host/server bare-metal hardware that is assigned to you. 服务器硬件嵌入在包含计算/服务器、网络和存储基础结构的较大模具中。The server hardware is embedded in larger stamps that contain compute/server, networking, and storage infrastructure. 这作为组合经过了 HANA 定制数据中心集成 (TDI) 认证。As a combination, it's HANA tailored data center integration (TDI) certified. Azure 上的 SAP HANA(大型实例)提供各种不同的服务器 SKU 或规模。SAP HANA on Azure (Large Instances) offers different server SKUs or sizes. 单元可包含 36 个 Intel CPU 内核和 768 GB 的内存,最多可包含 480 个 Intel CPU 内核和 24 TB 的内存。Units can have 36 Intel CPU cores and 768 GB of memory and go up to units that have up to 480 Intel CPU cores and up to 24 TB of memory.

基础结构模具中的客户隔离在租户中执行,详细情况如下所示:The customer isolation within the infrastructure stamp is performed in tenants, which looks like:

  • 网络:对于分配了租户的每个客户,通过虚拟网络实现基础结构堆栈中的客户隔离。Networking: Isolation of customers within infrastructure stack through virtual networks per customer assigned tenant. 一个租户分配给单个客户。A tenant is assigned to a single customer. 一个客户可以具有多个租户。A customer can have multiple tenants. 租户的网络隔离禁止基础结构模具级别中的租户之间进行网络通信,即使租户属于同一个客户。The network isolation of tenants prohibits network communication between tenants in the infrastructure stamp level, even if the tenants belong to the same customer.
  • 存储组件:通过分配了存储卷的存储虚拟机实现隔离。Storage components: Isolation through storage virtual machines that have storage volumes assigned to them. 存储卷只能分配给一个存储虚拟机。Storage volumes can be assigned to one storage virtual machine only. 存储虚拟机以独占方式分配给 SAP HANA TDI 认证的基础结构堆栈中的单个租户。A storage virtual machine is assigned exclusively to one single tenant in the SAP HANA TDI certified infrastructure stack. 因此,只能在一个特定相关租户中访问分配给存储虚拟机的存储卷。As a result, storage volumes assigned to a storage virtual machine can be accessed in one specific and related tenant only. 这些存储卷在部署的不同租户之间不可见。They aren't visible between the different deployed tenants.
  • 服务器或主机:服务器或主机单元不在客户或租户之间进行共享。Server or host: A server or host unit isn't shared between customers or tenants. 部署到客户的服务器或主机是分配给单个租户的原子裸机计算单元。A server or host deployed to a customer, is an atomic bare-metal compute unit that is assigned to one single tenant. 不使用硬件分区或软分区,这可能会导致某个客户与其他客户共享主机或服务器。No hardware partitioning or soft partitioning is used that might result in you sharing a host or a server with another customer. 分配给特定租户的存储虚拟机的存储卷会装载到这类服务器。Storage volumes that are assigned to the storage virtual machine of the specific tenant are mounted to such a server. 可以按独占方式向一个租户分配具有不同 SKU 的一个到多个服务器单元。A tenant can have one to many server units of different SKUs exclusively assigned.
  • 在 Azure 上的 SAP HANA(大型实例)基础结构模具中,会部署许多不同的租户,并通过网络、存储和计算级别上的租户概念使它们相互隔离。Within an SAP HANA on Azure (Large Instances) infrastructure stamp, many different tenants are deployed and isolated against each other through the tenant concepts on networking, storage, and compute level.

仅支持这些裸机服务器单元运行 SAP HANA。These bare-metal server units are supported to run SAP HANA only. SAP 应用层或工作负荷中间软件层在虚拟机中运行。The SAP application layer or workload middle-ware layer runs in virtual machines. 运行 Azure 上的 SAP HANA(大型实例)单元的基础结构模具连接到 Azure 网络服务骨干网。The infrastructure stamps that run the SAP HANA on Azure (Large Instances) units are connected to the Azure network services backbones. 因此可提供 Azure 上的 SAP HANA(大型实例)单元与 Azure 虚拟机之间的那种低延迟连接。In this way, low-latency connectivity between SAP HANA on Azure (Large Instances) units and virtual machines is provided.

本文档是介绍 Azure 上的 SAP HANA (大型实例)的几个文档之一。This document is one of several documents that cover SAP HANA on Azure (Large Instances). 本文档介绍了该解决方案提供的基本体系结构、责任和服务。This document introduces the basic architecture, responsibilities, and services provided by the solution. 此外介绍了解决方案的高级功能。High-level capabilities of the solution are also discussed. 对于大多数领域(如网络和连接),其他四个文档涵盖了详细信息并进行了深入介绍。For most other areas, such as networking and connectivity, four other documents cover details and drill-down information. Azure 上的 SAP HANA(大型实例)文档不涵盖 SAP NetWeaver 安装或 VM 中的 SAP NetWeaver 部署这些方面。The documentation of SAP HANA on Azure (Large Instances) doesn't cover aspects of the SAP NetWeaver installation or deployments of SAP NetWeaver in VMs. Azure 上的 SAP NetWeaver 在同一 Azure 文档容器的不同文档中介绍。SAP NetWeaver on Azure is covered in separate documents found in the same Azure documentation container.

HANA 大型实例指南的不同文档涵盖以下几个方面:The different documents of HANA Large Instance guidance cover the following areas:
