使用 vCore 购买模型的单一数据库的资源限制Resource limits for single databases using the vCore purchasing model
Azure SQL 数据库 Azure SQL Database
本文提供针对使用 vCore 购买模型的 Azure SQL 数据库中单一数据库的详细资源限制。This article provides the detailed resource limits for single databases in Azure SQL Database using the vCore purchasing model.
有关服务器上单一数据库的 DTU 购买模型限制，请参阅服务器上的资源限制概述。For DTU purchasing model limits for single databases on a server, see Overview of resource limits on a server.
可通过 Azure 门户、Transact-SQL、PowerShell、Azure CLI 或 REST API 为单一数据库设置服务层级、计算大小（服务目标）和存储量。You can set the service tier, compute size (service objective), and storage amount for a single database using the Azure portal, Transact-SQL, PowerShell, the Azure CLI, or the REST API.

注释Notes
注释 1：超大规模是具有单独计算和存储组件的多层体系结构：“超大规模”服务层级体系结构Note 1: Hyperscale is a multi-tiered architecture with separate compute and storage components: Hyperscale Service Tier Architecture
注释 2：对于本地计算副本 SSD 上的数据，延迟为 1-2 ms，这缓存最常用的数据页。Note 2: Latency is 1-2 ms for data on local compute replica SSD, which caches most used data pages. 从页面服务器检索数据的延迟更长。Higher latency for data retrieved from page servers.
