块 blob 存储用于流式处理和存储文档、视频、图片、备份和其他非结构化文本或二进制数据。

块 blob 存储的总成本取决于：

  • 每月存储的数据量。
  • 执行操作的次数和操作类型，以及任何数据传输成本。
  • 选择的数据冗余选项。

常见问题

Blob 存储

  • Blob 存储帐户专用于将数据作为 blob 存储，使用户可以根据该帐户中的数据访问频率指定访问层。常规用途帐户可用于存储 Blob、文件、磁盘、表和队列。

  • 否。常规用途存储帐户中的块 Blob 价格尚未改变。

  • 如果资源名称中出现“热”、“冷”或“存档”，则意味着该费用与 Blob 存储帐户相关。例如，如果看到“标准 IO - 冷块 blob (GB)”，则意味着正在使用 blob 存储帐户或常规用途 v2 帐户，并需支付相关费用。“标准 IO - 块 blob (GB)”是与常规用途存储帐户中的块 blob 使用相关的指标。

  • 高级* blob 存储仅适用于高级块 blob 存储帐户类型，最适合用于需要一致的低存储延迟的 IO 密集型工作负载。

    存储 GB 定价按“存档”、“冷”、“热”、“高级”的顺序逐层增加。相反，事务费用按“高级”、“热”、“冷”、“存档”的顺序逐层增加。“存档”层和“冷”层应分别用于几乎无访问和偶有访问的数据。“冷”层的可用性 SLA 比“热”层低。

    请注意，在 Blob 存储帐户和常规用途 v2 帐户中，可将 blob 的访问层设为“热”、“冷”或“存档”。目前，不能将数据从“高级”层分层到“热”、“冷”或“存档”层，也不能将“热”、“冷”或“存档”层中的数据分层到“高级”层。我们正致力于将来支持“高级”层的对象分层。

  • 将 blob 存储帐户或常规用途 v2 帐户从冷存储层切换到热存储层时，两个读取操作均需付费（按每 10,000 个 blob 和每 GB 数据检索收费）。例如，如果在 Blob 存储帐户或常规用途 v2 帐户中有 10,000 个 blob（等于 100 GB 的数据），将该帐户从“冷”切换到“热”时，需支付的数据检索费用为 10,000 x ($-/10,000) + 100 × $- = $-。

  • 对于常规用途 v2 帐户，只需为写入操作付费（按 10,000 计）。对于 blob 存储帐户，写入操作不收费。

  • 将数据写入到 GRS 帐户时，该数据将被复制到另一个 Azure 区域。异地复制数据传输费用是将数据复制到另一个 Azure 区域的带宽成本。将帐户从 RA-GRS 切换到 GRS 或 LRS（或者从 RA-GZRS 切换到 GZRS 或 ZRS）时，自转换日期起 30 天内仍将按 RA-GRS（或 RA-GZRS）对该帐户计费。

  • 不能从“存档”层直接读取 blob。要读取存档存储层中的 blob，用户首先必须将该层更改为热存储层或冷存储层。例如，从存档存储层检索并读取该层中已存在 90 天的单个 1,000 GB 存档 blob，需支付以下费用：

    从存档层进行数据检索（按 GB 计）：每月 $-/GB x 1,000 GB = $-

    解除冻结操作（SetBlobTier“存档”到“热”）：$-/10k = $-

    早期删除价格：（180 - 90 天）/30 天 x $-/GB/每月 x 1,000 = $-

    从“热”读取 blob 操作 = $-/10k = $-

    总计 = $- + $- + $- + $- = $-

  • 对于 blob 存储帐户和常规用途 v2 帐户，块 blob 存储的定价是相同的，除了数据写入（按 GB 计）和冷存储层中的提前删除费用。blob 存储帐户对冷存储层数据写入收费（按 GB 计），但不对冷存储层提前删除收费，而常规用途 v2 帐户则对冷存储层提前删除收费，但不对冷存储层数据写入收费（按 GB 计）。

  • 收取一次性费用（所有数据的总量乘以该主要区域的异地复制费用）。对于存储在“存档”层中的数据，从主要区域读取所有数据（按每 10,000 个 blob 和每 GB 数据检索）和将所有数据写入次要区域（按每 10,000 的写入操作）均需付费。

  • 目前，不能将数据从“高级”层分层到“热”、“冷”或“存档”层，也不能将“热”、“冷”或“存档”层中的数据分层到“高级”层。我们正致力于将来支持“高级”层的对象分层。

    若要移动数据，可通过使用新的通过 URL 放置块 API（示例代码）或支持此 API 的 AzCopy 版本来同步复制 blob。“通过 URL 放置块”可同步复制数据服务器端，这意味着数据复制在调用结束时完成，所有数据移动都在 Azure 存储内部进行。

Azure Storage Reserved Capacity FAQs

  • Azure Storage Reserved Capacity helps you lower your data storage cost by committing to one-year or three-years of Azure Storage on Block Blob or Azure Data Lake Storage Gen2.

  • Azure Storage Reserved Capacity provides options to purchase standard storage capacity in units of 100 TB and 1 PB per month blocks for one-year or three-years terms. To purchase Azure Storage Reserved Capacity, you can choose the required number of units for Hot, Cool or Archive storage tier on any of the available storage redundancies (e.g. LRS, ZRS, GRS), and for a specific region (e.g., US West 2). Additionally, you can choose to pay with a single, upfront payment or monthly payments.

    Get started in the Azure portal.

  • Reservations are available today for 100 TB or 1 PB blocks, with higher discounts applicable on 1 PB blocks. In the reservation purchase experience through Azure portal, Microsoft may provide you recommendations based on your previous usage to help determine the sizes you should purchase.

  • For Enterprise Agreement (EA) customers, Azure Monetary Commitment will be used first to purchase Azure Storage Reserved Capacity. In scenarios where EA customers have used all their monetary commitment, Azure Storage Reserved Capacity can still be purchased, and those purchases will be invoiced for the single, upfront payment on their next overage bill.

    For customers purchasing via Azure.com, at the time of purchase, the credit card on file will be charged for the full upfront payment (or monthly fixed payments) of Azure Storage Reservations.

  • As soon as purchase is completed. If the purchase is made in the middle of the month, the reserved amount is pro-rated for that month.

  • Azure Storage Reserved Capacity is purchased at a single subscription or shared resource group scope. Therefore, reservation is applied to your usage aggregated to the purchased scope and cannot be limited to a specific storage account, container or object within the subscription.

  • No, all purchases are at the aggregate, subscription level only. Purchases cannot be split across multiple subscriptions.

  • Azure Storage Reserved Capacity allows you to purchase data storage capacity for Standard (GPv2) storage and Blob Storage accounts. The purchased capacity can be used for Block Blobs and Azure Data Lake Storage Gen2. Currently Premium Storage, other storage types (Managed Disks, Files, Queues, Page Blobs and Tables), early deletion charges, operations and data transfer are not included in Azure Storage Reserved Capacity.

  • Azure Storage Reserved Capacity is purchased for a specific region (e.g., US West 2 or any other region of your choice), storage tier (e.g., Hot, Cool or Archive) and redundancy (e.g., LRS, GRS or ZRS), and therefore cannot be used outside these constructs. You can always purchase an additional Azure Storage Reserved Capacity for your data storage need in other regions or redundancies.

  • Select the ‘Reservations’ menu on the left side of the Azure portal to view all the Azure Reserved Storage Capacity details associated with your account. All the details associated with the Azure Storage Reserved Capacity that you have purchased will be displayed on the right.

  • An exchange allows you to receive a prorated refund based on the unused amount, which applies fully to the purchase price of a new Azure Storage Reserved Capacity. A cancellation terminates your Azure Storage Reserved Capacity and you'll receive a prorated refund based on the remaining term of the Azure Storage Reserved Capacity minus a 12 percent early termination fee.

  • There's no limit on the number of exchanges you can make. Additionally, there's no fee associated with an exchange. The new Azure Storage Reserved Capacity purchased however must be of equal or greater value than the prorated credit from the original Azure Storage Reserved Capacity. Additionally, Azure Storage Reserved Capacity can only be exchanged with another Azure Storage Reserved Capacity.

  • You can cancel Azure Storage Reserved Capacity at any time (up to $50000 per year). Cancelling allows you to return the remaining months of an Azure Storage Reserved Capacity back to Microsoft for an early termination fee of 12 percent. The remaining prorated balance, minus the fee, will be refunded to your original purchase.

  • If you decide that you wish to exchange your Azure Storage Reserved Capacity (e.g., exchange a purchase 7 units of 100 TB block for 1 unit of 1 PB block ), you can initiate exchange from management portal and view the inventory of Azure Reserved Capacities. Click on a purchased capacity and two buttons will appear in the command bar stating “refund” or “exchange”. Once selected, a support ticket, prepopulated with all of the Azure Storage Reserved Capacity details, will open. Once submitted, the request will be processed, and an email will be sent to you to confirm completion of the request.

  • You will receive email notifications 30 days prior to expiration, and again on the expiration date. Once the reservation expires, deployed capacity will continue to run and will be billed at the then current pay-as-you-go rate.

  • Let’s assume you purchased 100 TB of reserved capacity for 1-year for LRS Hot Storage in US West 2.

    100 TB reserved capacity pricing for Hot LRS Data Stored (US West 2) = $18540.

    You can pay the full amount upfront, or pay fixed monthly installments at $- every month for the next 12 months. Let’s assume you signed up for a monthly reservation payment plan.

    Scenario 1 - If in any given month within the reservation period, you use 101 TB, your bill will include $- for 100 TB of reserved capacity and $19 for 1 TB at pay-go prices. Your total bill for data stored that month is now $1564.

    Scenario 2 – If in any given month within the reservation period, you use 80 TB of capacity, your bill will include $- for 100 TB of reserved capacity.
