什麼是 SAP HANA on Azure (大型執行個體)?What is SAP HANA on Azure (Large Instances)?

SAP HANA on Azure (大型執行個體) 是 Azure 獨有的解決方案。SAP HANA on Azure (Large Instances) is a unique solution to Azure. 除了提供虛擬機器讓您部署和執行 SAP HANA 外,Azure 還可讓您在您專屬的裸機伺服器上執行並部署 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. SAP HANA on Azure (大型執行個體) 解決方案會建置在指派給您的非共用主機/伺服器裸機硬體上。The SAP HANA on Azure (Large Instances) solution builds on non-shared host/server bare-metal hardware that is assigned to you. 伺服器硬體會內嵌在更大的戳記中,該戳記會包含計算/伺服器、網路和儲存體基礎結構。The server hardware is embedded in larger stamps that contain compute/server, networking, and storage infrastructure. 這是經過 HANA Tailored Data Center Integration (TDI) 認證的組合。As a combination, it's HANA tailored data center integration (TDI) certified. SAP HANA on Azure (大型執行個體) 提供不同的 SKU 或大小。SAP HANA on Azure (Large Instances) offers different server SKUs or sizes. 單位可具有 36 Intel CPU 核心和 768 GB 記憶體,並移至具有多達 480 Intel CPU 核心和多達 24 TB 記憶體的單位。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.

客戶在基礎結構戳記內是利用租用戶來區隔,如下所示:The customer isolation within the infrastructure stamp is performed in tenants, which looks like:

  • 網路:透過每個客戶的虛擬網路的基礎結構堆疊內區隔客戶指派給租用戶。Networking: Isolation of customers within infrastructure stack through virtual networks per customer assigned tenant. 一個租用戶只會指派給單一客戶。A tenant is assigned to a single customer. 但一個客戶可以擁有多個租用戶。A customer can have multiple tenants. 租用戶的網路區隔會在基礎結構戳記層級禁止租用戶之間的網路通訊,即使租用戶屬於相同客戶亦然。The network isolation of tenants prohibits network communication between tenants in the infrastructure stamp level, even if the tenants belong to the same customer.
  • 儲存體元件:透過已指派給它們的儲存體磁碟區的存放虛擬機器的隔離。Storage components: Isolation through storage virtual machines that have storage volumes assigned to them. 存放磁碟區只能指派給一個存放虛擬機器。Storage volumes can be assigned to one storage virtual machine only. 一個存放虛擬機器只會指派給已通過 SAP HANA TDI 認證之基礎結構堆疊中的一個租用戶。A storage virtual machine is assigned exclusively to one single tenant in the SAP HANA TDI certified infrastructure stack. 因此,指派給存放虛擬機器的存放磁碟區只能在一個特定且相關的租用戶中受到存取。As a result, storage volumes assigned to a storage virtual machine can be accessed in one specific and related tenant only. 它們在已部署的不同租用戶之間是不可見的。They aren't visible between the different deployed tenants.
  • 伺服器或 vsphere 主機:在伺服器或主機單位不是客戶或租用戶之間共用。Server or host: A server or host unit isn't shared between customers or tenants. 部署給客戶的伺服器或主機是不可分割的裸機計算單位,並且只會指派給一個租用戶。A server or host deployed to a customer, is an atomic bare-metal compute unit that is assigned to one single tenant. 無法使用任何可讓您與其他客戶共用主機或伺服器的硬體分割或軟體分割。No hardware partitioning or soft partitioning is used that might result in you sharing a host or a server with another customer. 指派給特定租用戶之存放虛擬機器的存放磁碟區會掛接到這類伺服器。Storage volumes that are assigned to the storage virtual machine of the specific tenant are mounted to such a server. 一個租用戶可以獨佔方式獲得不同 SKU 的一個到多個伺服器單位。A tenant can have one to many server units of different SKUs exclusively assigned.
  • SAP HANA on Azure (大型執行個體) 的基礎結構戳記內會部署許多不同的租用戶,並透過租用戶概念在網路、儲存體和計算層級將這些租用戶彼此區隔。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.

這些裸機伺服器單位只支援用來執行 SAP HANA。These bare-metal server units are supported to run SAP HANA only. SAP 應用程式層或工作負載中介軟體層會在虛擬機器中執行。The SAP application layer or workload middle-ware layer runs in virtual machines. 執行 SAP HANA on Azure (大型執行個體) 單位的基礎結構戳記會連線至 Azure 網路服務骨幹。The infrastructure stamps that run the SAP HANA on Azure (Large Instances) units are connected to the Azure network services backbones. 如此,即可提供 SAP HANA on Azure (大型執行個體) 單位與虛擬機器之間的低延遲連線。In this way, low-latency connectivity between SAP HANA on Azure (Large Instances) units and virtual machines is provided.

在多份說明 SAP HANA on Azure (大型執行個體) 的文件中,本文件是其中之一。This document is one of several documents that cover SAP HANA on Azure (Large Instances). 本文件將介紹解決方案所提供的基本架構、責任和服務。This document introduces the basic architecture, responsibilities, and services provided by the solution. 此外也會討論解決方案的高階功能。High-level capabilities of the solution are also discussed. 其他四份文件會詳述並深入探討其他大多數的層面,例如網路和連線。For most other areas, such as networking and connectivity, four other documents cover details and drill-down information. SAP HANA on Azure (大型執行個體) 的文件並未說明 SAP NetWeaver 安裝方面或在 VM 中部署 SAP NetWeaver 方面的內容。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 可在相同 Azure 說明文件容器中的個別文件中找到。SAP NetWeaver on Azure is covered in separate documents found in the same Azure documentation container.

HANA 大型執行個體指南的不同文件涵蓋下列領域:The different documents of HANA Large Instance guidance cover the following areas:
