Overview

The IoT platform stores data generated during device access and routine device management. The IoTDA console integrates the storage management function of IoT Analytics. You can store historical device data for free for a maximum of 7 days, either in warm or cold data storage mode.

• Warm data storage: optimized storage mode based on IoT time sequence features. This storage offers excellent data compression and supports efficient aggregation query in the time dimension. Data that needs to be queried frequently should be kept in warm storage.
• Cold data storage: cost-effective object storage mode, suitable for archiving historical IoT data. The offline analysis engine of IoT Analytics can easily process petabytes of data.

Storage Configuration

When using storage management for the first time, you must enable mutual access of IoTDA and IoT Analytics and apply for the open beta test (OBT) of IoT Analytics. During the OBT, only data storage is provided for free for seven days by default. If you want to continue using the service, you can change the storage duration and pay for the service on demand.

1. Log in to the IoTDA console.
2. In the navigation pane, choose Storage Management, select Authorize mutual access between IoT Data Access and IoT Analytics, and click Subscribe Now.

   

3. If you have not subscribed to IoT Analytics, the page for applying for the OBT is displayed. Complete the information on the page, select I have read and agree to the OBT Trial Use Agreement, and click Apply Now. After the service is subscribed to, you will receive an SMS message and a message notification from the HUAWEI CLOUD website.

   

4. Log in to the IoTDA console, choose Storage Management in the navigation pane, and click Use Now in the upper part of the page to access IoT Analytics.
   

   Based on the IoT asset models, IoT Analytics streamlines IoT data integration, cleaning, storage, analysis, and visualization to provide one-stop services, reducing the development threshold and period and monetizing IoT data.

After the storage configuration is complete, you can click Query Historical Data in the upper right corner of the device list page to analyze and explore historical data of all devices in batches. You can also view the historical data of an individual device on the device details page.
