虛擬核心模型概觀vCore model overview

虛擬核心(vCore)模型提供數個優點:The virtual core (vCore) model provides several benefits:

  • 較高的計算、記憶體、IO 和儲存體限制。Higher compute, memory, IO, and storage limits.
  • 控制硬體世代,以更符合工作負載的計算和記憶體需求。Control over the hardware generation to better match compute and memory requirements of the workload.
  • Azure Hybrid Benefit (AHB)保留實例(RI)的定價折扣。Pricing discounts for Azure Hybrid Benefit (AHB) and Reserved Instance (RI).
  • 提高計算能力的硬體詳細資料中有更大的透明度;有助於規劃從內部部署進行遷移。Greater transparency in the hardware details that power the compute; facilitates planning for migrations from on-premises deployments.

服務層次Service tiers

VCore 模型中的服務層選項包括一般用途、業務關鍵和超大規模資料庫。Service tier options in the vCore model include General Purpose, Business Critical, and Hyperscale. 服務層通常會定義儲存體架構、空間和 IO 限制,以及與可用性和嚴重損壞修復相關的商務持續性選項。The service tier generally defines the storage architecture, space and IO limits, and business continuity options related to availability and disaster recovery.

選擇服務層級Choosing a service tier

如需針對特定工作負載選取服務層級的詳細資訊,請參閱下列文章:For information on selecting a service tier for your particular workload, see the following articles:

計算層Compute tiers

VCore 模型中的計算層選項包括布建和無伺服器計算層。Compute tier options in the vCore model include the provisioned and serverless compute tiers.

佈建的計算Provisioned compute

布建的計算層提供了與工作負載活動無關的特定計算資源量,並以每小時固定價格的計算數量計費。The provisioned compute tier provides a specific amount of compute resources that are continuously provisioned independent of workload activity, and bills for the amount of compute provisioned at a fixed price per hour.

無伺服器計算Serverless compute

無伺服器計算層會根據工作負載活動自動調整計算資源,並以每秒使用的計算量來計費。The serverless compute tier auto-scales compute resources based on workload activity, and bills for the amount of compute used per second.

硬體世代Hardware generations

VCore 模型中的硬體產生選項包括 Gen 4/5、M 系列(預覽)和 Fsv2 系列(預覽)。Hardware generation options in the vCore model include Gen 4/5, M-series (preview), and Fsv2-series (preview). 硬體世代通常會定義計算和記憶體限制,以及影響工作負載效能的其他特性。The hardware generation generally defines the compute and memory limits and other characteristics that impact the performance of the workload.

第4代/第5代Gen4/Gen5

  • 第4代/第5代硬體提供平衡的計算和記憶體資源,適用于不具較高記憶體、較高 vCore 或更快速的單一 vCore 需求(如 Fsv2 系列或 M 系列所提供)的大部分資料庫工作負載。Gen4/Gen5 hardware provides balanced compute and memory resources, and is suitable for most database workloads that do not have higher memory, higher vCore, or faster single vCore requirements as provided by Fsv2-series or M-series.

如需第4代/第5代可用的區域,請參閱第4代/第5代 availabilityFor regions where Gen4/Gen5 is available, see Gen4/Gen5 availability.

Fsv2 系列(預覽)Fsv2-series (preview)

  • Fsv2 系列是一種計算優化硬體選項,可為最多 CPU 需求的工作負載提供低 CPU 延遲和高頻率速度。Fsv2-series is a compute optimized hardware option delivering low CPU latency and high clock speed for the most CPU demanding workloads.
  • 視工作負載而定,Fsv2 系列可以提供比第5代更多的每個 vCore CPU 效能,而 72 vCore 大小可提供比虛擬核心上80第5代更多的 CPU 效能。Depending on the workload, Fsv2-series can deliver more CPU performance per vCore than Gen5, and the 72 vCore size can provide more CPU performance for less cost than 80 vCores on Gen5.
  • Fsv2 提供比其他硬體更少的記憶體和 tempdb,因此,這些限制的相關工作負載可能會想要改為考慮第5代或 M 系列。Fsv2 provides less memory and tempdb per vCore than other hardware so workloads sensitive to those limits may want to consider Gen5 or M-series instead.  

如需 Fsv2 系列的可用區域,請參閱Fsv2 系列可用性For regions where Fsv2-series is available, see Fsv2-series availability.

M 系列(預覽)M-series (preview)

  • M 系列是記憶體優化硬體選項,適用于需要更多記憶體和更高計算限制的工作負載,而不是由第5代所提供。M-series is a memory optimized hardware option for workloads demanding more memory and higher compute limits than provided by Gen5.
  • M 系列提供每 vCore 29 GB 和128虛擬核心,這會將相對於8月第5代的記憶體限制增加到將近 4 TB。M-series provides 29 GB per vCore and 128 vCores, which increases the memory limit relative to Gen5 by 8x to nearly 4 TB.

若要啟用訂用帳戶和區域的 M 系列硬體,必須開啟支援要求。To enable M-series hardware for a subscription and region, a support request must be open. 如果支援要求經過核准,則 M 系列的選擇和布建體驗會遵循與其他硬體世代相同的模式。If the support request is approved, then the selection and provisioning experience of M-series follows the same pattern as for other hardware generations. 如需 M 系列可用的區域,請參閱m 系列可用性For regions where M-series is available, see M-series availability.
