Azure NetApp 文件的资源限制Resource limits for Azure NetApp Files

了解 Azure NetApp 文件的资源限制,可帮助你管理卷。Understanding resource limits for Azure NetApp Files helps you manage your volumes.

Maxfiles 限制 Maxfiles limits

Azure NetApp 文件卷具有称为 maxfiles 的限制。Azure NetApp Files volumes have a limit called maxfiles. Maxfiles 限制是卷可以包含的文件数。The maxfiles limit is the number of files a volume can contain. 根据卷 (配额) 大小对 Azure NetApp 文件卷的 maxfiles 限制进行索引。The maxfiles limit for an Azure NetApp Files volume is indexed based on the size (quota) of the volume. 对于每个 TiB 的预配卷大小,卷的 maxfiles 限制会增加或降低20000000文件的速率。The maxfiles limit for a volume increases or decreases at the rate of 20 million files per TiB of provisioned volume size.

服务基于其预配的大小动态调整卷的 maxfiles 限制。The service dynamically adjusts the maxfiles limit for a volume based on its provisioned size. 例如,最初配置为大小为 1 TiB 的卷的 maxfiles 限制将为20000000。For example, a volume configured initially with a size of 1 TiB would have a maxfiles limit of 20 million. 对卷大小的后续更改会导致自动 readjustment 基于以下规则的 maxfiles 限制:Subsequent changes to the size of the volume would result in an automatic readjustment of the maxfiles limit based on the following rules:

卷大小 (配额) Volume size (quota) Maxfiles 限制的自动 readjustmentAutomatic readjustment of the maxfiles limit
<= 1 TiB<= 1 TiB 2000 万20 million
> 1 TiB,但 <= 2 TiB> 1 TiB but <= 2 TiB 4000000040 million
> 2 TiB,但 <= 3 TiB> 2 TiB but <= 3 TiB 6000 万60 million
> 3 TiB,但 <= 4 TiB> 3 TiB but <= 4 TiB 8000000080 million
> 4 TiB> 4 TiB 1 亿100 million

如果已为卷分配至少 4 TiB 的配额,则可以启动 支持请求 ,以将 maxfiles 限制增加到100000000以上。If you have already allocated at least 4 TiB of quota for a volume, you can initiate a support request to increase the maxfiles limit beyond 100 million. 对于增加的每个100000000文件 (或) 的分数,需要将相应的卷配额增加 4 TiB。For every 100 million files you increase (or a fraction thereof), you need to increase the corresponding volume quota by 4 TiB. 例如,如果将100000000文件中的 maxfiles 限制增加到200000000个文件 (或) 之间的任意数字,则需要将卷配额从4个 TiB 增加到8个 TiB。For example, if you increase the maxfiles limit from 100 million files to 200 million files (or any number in between), you need to increase the volume quota from 4 TiB to 8 TiB.

请求限制增加 Request limit increase

可以创建 Azure 支持请求,增加上表中的可调整限制。You can create an Azure support request to increase the adjustable limits from the table above.
