Batch 服务配额和限制Batch service quotas and limits

与其他 Azure 服务一样,与 Batch 服务关联的某些资源存在限制。As with other Azure services, there are limits on certain resources associated with the Batch service. 其中的许多限制是 Azure 在订阅或帐户级别应用的默认配额。Many of these limits are default quotas applied by Azure at the subscription or account level. 本文描述这些默认值,以及如何请求提高配额。This article discusses those defaults, and how you can request quota increases.

设计和增加 Batch 工作负荷时,请记住这些配额。Keep these quotas in mind as you design and scale up your Batch workloads. 例如,如果池没有达到指定的计算节点目标数量,那么可能是已达到 Batch 帐户的核心配额限制。For example, if your pool doesn't reach the target number of compute nodes you specified, you might have reached the core quota limit for your Batch account.

可以在单个批处理帐户中运行多个批处理工作负荷,或者在相同订阅的不同 Azure 区域的批处理帐户之间分散工作负荷。You can run multiple Batch workloads in a single Batch account, or distribute your workloads among Batch accounts that are in the same subscription, but in different Azure regions.

如果打算在 Batch 中运行生产工作负荷,可能需要将一个或多个配额提高到默认值以上。If you plan to run production workloads in Batch, you may need to increase one or more of the quotas above the default. 如果需要提高配额,可以免费提出在线 客户支持请求If you want to raise a quota, you can open an online customer support request at no charge.

资源配额Resource quotas

配额是一种信用限制,不附带容量保证。A quota is a credit limit, not a capacity guarantee. 如果有大规模的容量需求,请联系 Azure 支持。If you have large-scale capacity needs, please contact Azure support.

另请注意,配额并非获得保证的值。Also note that quotas are not guaranteed values. 配额因 Batch 服务的变化而变化,用户也可以请求更改配额值。Quotas can vary based on changes from the Batch service or a user request to change a quota value.

资源Resource 默认限制Default Limit 最大限制Maximum Limit
每个区域每个订阅的批处理帐户数Batch accounts per region per subscription 1 - 31 - 3 5050
每个批处理帐户的专用核心数Dedicated cores per Batch account 10 - 10010 - 100 不适用1N/A1
每个批处理帐户的低优先级核心数Low-priority cores per Batch account 10 - 10010 - 100 N/A2N/A2

默认限制因用于创建 Batch 帐户的订阅类型而异。Default limits vary depending on the type of subscription you use to create a Batch account. 显示的核心配额适用于 Batch 服务模式下的 Batch 帐户。Cores quotas shown are for Batch accounts in Batch service mode. 查看 Batch 帐户中的配额View the quotas in your Batch account.

1 可以增加每个批处理帐户的专用核心数,但不指定其最大数目。1 The number of dedicated cores per Batch account can be increased, but the maximum number is unspecified. 请联系 Azure 支持以讨论增加选项。Contact Azure support to discuss increase options.

2 可以增加每个批处理帐户的低优先级核心数,但不指定其最大数目。2 The number of low-priority cores per Batch account can be increased, but the maximum number is unspecified. 请联系 Azure 支持以讨论增加选项。Contact Azure support to discuss increase options.

3 已完成的作业和作业计划不受限制。3 Completed jobs and job schedules are not limited.

4 如果请求增加的配额超出此限制,请与 Azure 支持部门联系。4 Contact Azure support if you want to request an increase beyond this limit.

用户订阅模式中的核心配额Cores quotas in user subscription mode

如果创建了 Batch 帐户,并将池分配模式设置为“用户订阅”,则会以不同的方式应用配额。If you created a Batch account with pool allocation mode set to user subscription, quotas are applied differently. 在此模式下,会在创建池后直接在订阅中创建 Batch VM 和其他资源。In this mode, Batch VMs and other resources are created directly in your subscription when a pool is created. Azure Batch 核心配额不会应用到在此模式下创建的帐户。The Azure Batch cores quotas do not apply to an account created in this mode. 对于此类帐户,将应用订阅中的区域计算核心数和其他资源的配额。Instead, the quotas in your subscription for regional compute cores and other resources are applied. Azure 订阅和服务的限制、配额和约束中详细了解这些配额。Learn more about these quotas in Azure subscription and service limits, quotas, and constraints.

池大小限制Pool size limits

池大小限制由 Batch 服务设置。Pool size limits are set by the Batch service. 资源配额不同,这些值无法更改。Unlike resource quotas, these values cannot be changed. 只有那些使用节点间通信和自定义映像的池的限制不同于标准配额。Only pools with inter-node communication and custom images have restrictions different from the standard quota.

资源Resource 最大限制Maximum Limit
启用了节点间通信的池中的计算节点Compute nodes in inter-node communication enabled pool
Batch 服务池分配模式Batch service pool allocation mode 100100
Batch 订阅池分配模式Batch subscription pool allocation mode 8080
使用托管映像资源创建的池中的计算节点1Compute nodes in pool created with a managed image resource1
专用节点Dedicated nodes 20002000
低优先级节点Low-priority nodes 10001000

1 适用于未启用节点间通信的池。1 For pools that are not inter-node communication enabled.

其他限制Other limits

其他由 Batch 服务设置的限制。Additional limits set by the Batch service. 资源配额不同,这些值无法更改。Unlike resource quotas, these values cannot be changed.

1 最长任务生存期(从添加到作业时算起到任务完成时结束)为 180 天。1 The maximum lifetime of a task, from when it is added to the job to when it completes, is 180 days. 已完成的任务会保存 7 天;最长生存期内未完成的任务的数据不可访问。Completed tasks persist for seven days; data for tasks not completed within the maximum lifetime is not accessible.
