Requirement Analysis

Requirement Analysis

This section describes how InfoTier meets the data storage and management requirements of a TV station.

Requirement Source

The TV station uses the OceanStor 90000 to store and manage data. Some facts of the data services in this TV station:

  • Some data is accessed frequently, and some data is seldom accessed.
  • Data of VIP customers is accessed frequently.
  • New files are accessed frequently.
  • Data access frequencies gradually decrease.

This TV station requires automatic data categorizing and customized intelligent data storage. Its specific requirements are as follows:

  • Automatic data categorizing

    Data is automatically categorized and stored based on specific policies.

  • Flexible policies of data storage

    When service requirements change, the storage system can automatically adjust data storage locations based on the new data storage policy, improving storage system performance and cutting down costs.

Requirement Analysis and Conclusions

The requirements indicate that this TV station needs a solution that can automatically categorize and intelligently manage data. Table 3-8 lists considerations when selecting a solution.

Table 3-8  Considerations in selecting an automatic data categorizing and intelligent data management solution

Consideration

Description

Data storage location

Store different data in different locations to achieve category-based data management.

Hotspot data detection

To manage data with different access popularity based on their categories, hot data criteria is required.

Distinguishing of critical user data

Priority must be given to critical user data.

Storage capacity reliability

When space in the storage device becomes insufficient, customers must be notified and corresponding solutions must be available.

Data storage policies adaptable to service changes

Data storage policies should be modifiable when services change.

Detailed analysis must incorporate the following:

  • Data storage location

    Data storage involves the initial storage of newly created data and the storage relocation of existing data. Both are determined by storage policies.

  • Hot data detection

    Statistics of newly created files, frequently accessed data, and seldom accessed data must be collected to determine hotspot data.

  • Distinguishing of critical user data

    Data of VIP customers are frequently accessed, and must be high priority.

  • Storage capacity reliability

    When space in a storage node becomes insufficient, notifications will be displayed, and data will be relocated to those storage nodes with sufficient space.

  • Data storage policies adaptable to service changes

    Data storage policies should be adjusted to meet new service requirements.

Based on the preceding analysis, InfoTier is the optimal solution for this TV station. Details of the solution are as follows:

  • This TV station needs to purchase OceanStor 9000 P25 and C72.
  • It should use P25 nodes to deploy performance node pools and C72 nodes to deploy capacity node pools.
  • In addition, the TV station must obtain the required license to enable InfoTier and make file pool policies to intelligently manage file storage.
