托管磁盘Managed Disks

什么是 Azure 托管磁盘?What is Azure Managed Disks?

托管磁盘是一种通过处理存储帐户管理来简化 Azure IaaS VM 的磁盘管理的功能。Managed Disks is a feature that simplifies disk management for Azure IaaS VMs by handling storage account management for you. 有关详细信息,请参阅托管磁盘概述For more information, see the Managed Disks overview.

如果从现有的 VHD(80 GB)创建标准托管磁盘,需要多少费用?If I create a standard managed disk from an existing VHD that's 80 GB, how much will that cost me?

从 80 GB VHD 创建的标准托管磁盘被视为下一个可用的标准磁盘大小(S10 磁盘)。A standard managed disk created from an 80-GB VHD is treated as the next available standard disk size, which is an S10 disk. 我们按 S10 磁盘定价收费。You're charged according to the S10 disk pricing. 有关详细信息,请参阅定价页For more information, see the pricing page.

非托管磁盘或页 blob 是否支持 P4 和 P6 磁盘大小?Are P4 and P6 disk sizes supported for unmanaged disks or page blobs?

非托管磁盘和页 blob 不支持 P4 (32 GiB) 和 P6 (64 GiB) 磁盘大小作为默认磁盘层。P4 (32 GiB) and P6 (64 GiB) disk sizes are not supported as the default disk tiers for unmanaged disks and page blobs. 需要显式设置 Blob 层,将其设为 P4 和 P6,以便存储映射到这些层的磁盘。You need to explicitly set the Blob Tier to P4 and P6 to have your disk mapped to these tiers. 如果使用少于 32 GiB 或介于 32 GiB 到 64 GiB 之间的磁盘大小或内容长度部署非托管磁盘或页 blob 而不设置 Blob 层,则将继续停留在 P10(500 IOPS 和 100 MiB/秒)和映射的定价层。If you deploy a unmanaged disk or page blob with the disk size or content length less than 32 GiB or between 32 GiB to 64 GiB without setting the Blob Tier, you will continue to land on P10 with 500 IOPS and 100 MiB/s and the mapped pricing tier.

如果在支持较小磁盘(约 2017 年 6 月 15 日)之前创建了小于 64 GiB 的高级托管磁盘,将如何计费?If my existing premium managed disk less than 64 GiB was created before the small disk was enabled (around June 15, 2017), how is it billed?

根据 P10 定价层继续对小于 64 GiB 的现有高级小磁盘计费。Existing small premium disks less than 64 GiB continue to be billed according to the P10 pricing tier.

如何将小于 64 GiB 的高级小磁盘的磁盘层级从 P10 切换到 P4 或 P6?How can I switch the disk tier of small premium disks less than 64 GiB from P10 to P4 or P6?

可以拍摄小磁盘的快照,然后创建磁盘以自动根据预配大小将定价层切换到 P4 或 P6。You can take a snapshot of your small disks and then create a disk to automatically switch the pricing tier to P4 or P6 based on the provisioned size.

是否可以将托管磁盘的大小从小于 4 TiB 调整到最新引入的磁盘大小(最大大小为 32 TiB)?Can you resize existing Managed Disks from sizes fewer than 4 tebibytes (TiB) to new newly introduced disk sizes up to 32 TiB?

是的。Yes.

Azure 备份和 Azure Site Recovery 服务支持的最大磁盘大小是多少?What are the largest disk sizes supported by Azure Backup and Azure Site Recovery service?

Azure Site Recovery 支持的最大磁盘大小为 8 TiB。The largest disk size supported by Azure Site Recovery is 8 TiB. 目前 Azure Site Recovery 中尚不支持高达 32 TiB 的大型磁盘。Support for the larger disks up to 32 TiB is not yet available in Azure Site Recovery.

标准 SSD 和标准 HDD 磁盘大磁盘大小 (>4 TiB) 用于实现优化磁盘 IOPS 和带宽建议的 VM 大小是多少?What are the recommended VM sizes for larger disk sizes (>4 TiB) for Standard SSD and Standard HDD disks to achieve optimized disk IOPS and Bandwidth?

要使标准 SSD 和标准 HDD 大型磁盘 (>4 TiB) 的磁盘吞吐量超过 500 IOPS 和 60 MiB/秒,我们建议部署下列 VM 大小之一的新 VM 来优化性能:B 系列、DSv2 系列、Dsv3 系列、ESv3 系列、Fs 系列、Fsv2 系列、M 系列或 NCv3 系列。To achieve the disk throughput of Standard SSD and Standard HDD large disk sizes (>4 TiB) beyond 500 IOPS and 60 MiB/s, we recommend you deploy a new VM from one of the following VM sizes to optimize your performance: B-series, DSv2-series, Dsv3-Series, ESv3-Series, Fs-series, Fsv2-series, M-series, or NCv3-series. 将大型磁盘附加到现有 VM 或者不使用上述建议大小的 VM 可能会遇到性能下降的问题。Attaching large disks to existing VMs or VMs that are not using the recommended sizes above may experience lower performance.

如何升级在大型磁盘预览期部署的磁盘 (> 4 TiB),以便在正式版中获得更高的 IOPS 和带宽?How can I upgrade my disks (>4 TiB) which were deployed during the larger disk sizes preview in order to get the higher IOPS & bandwidth at GA?

可以停止然后启动该磁盘附加到 VM,或者分离然后重新附加磁盘。You can either stop and start the VM that the disk is attached to or, detach and re-attach your disk. 在正式版中,高级 SSD 和标准 SSD 大型磁盘的性能目标已提高。The performance targets of larger disk sizes have been increased for both premium SSDs and standard SSDs at GA.

哪些区域支持大于 8 TiB、16 TiB 和 32 TiB 的托管磁盘大小?What regions are the managed disk sizes of 8 TiB, 16 TiB, and 32 TiB supported in?

是否支持在所有磁盘大小上启用主机缓存?Do we support enabling Host Caching on all disk sizes?

4 TiB 以下的磁盘大小支持主机缓存(只读和读/写)。Host Caching (ReadOnly and Read/Write) is supported on disk sizes less than 4 TiB. 这意味着,预配到最高 4095 GiB 的任何磁盘都可以利用主机缓存。This means any disk that is provisioned up to 4095 GiB can take advantage of Host Caching. 大于或等于 4096 GiB 的磁盘大小不支持主机缓存。Host caching is not supported for disk sizes more than or equal to 4096 GiB. 例如,预配到 4095 GiB 的 P50 高级磁盘可以利用主机缓存,而预配到 4096 GiB 的 P50 磁盘不能利用主机缓存。For example, a P50 premium disk provisioned at 4095 GiB can take advantage of Host caching and a P50 disk provisioned at 4096 GiB cannot take advantage of Host Caching. 建议利用较小磁盘大小的缓存,以便通过缓存到 VM 的数据观察到明显的性能提升。We recommend leveraging caching for smaller disk sizes where you can expect to observe better performance boost with data cached to the VM.
