Requirement Analysis

Requirement Analysis

This section analyzes the multi-zone storage requirements of a TV station's program production center and provides a storage solution.

Requirement

The program production center uses an online media assets library and has both high-definition (HD) and standard-definition (SD) services. This production center needs a storage system that can process both the HD and SD services. Media assets services require high bandwidth, low latency, and the shortest path for application servers to access the storage network. Figure 2-14 shows a typical network diagram.

Figure 2-14  Typical network diagram
The storage requirements of HD and SD services are described as follows:
  • HD services require concurrent access at a bit rate of 200 Mbit/s, high storage bandwidth, average I/O latency smaller than 40 ms, and a storage capacity of 130 TB.
  • SD services require concurrent access at a bit rate of 25 Mbit/s, average I/O latency smaller than 40 ms, and a storage capacity of 50 TB.

SD services grow slowly but HD services grow rapidly. Therefore, the storage system must be capable of allocating storage resources to the two types of services on demand and has a flexible scalability.

In addition, the storage system must be managed and maintained in a unified manner to reduce the operation and maintenance (O&M) costs.

Analysis and Conclusion

Based on the requirement analysis, it is concluded that the program production center needs a storage system that supports both HD and SD services. The solution is as follows:

  • Configure an OceanStor 9000 with six P25 nodes. This storage system supports HD and SD services, reducing the O&M costs while enabling the unified management.
  • Use InfoEqualizer to configure two zones in the OceanStor 9000 and add different number of nodes to the two zones to support HD and SD service clients separately.
  • The administrator configures a forwarder for the DNS server on the customer's network. Then, the DNS server can forward the OceanStor 9000 domain name resolution requests to the OceanStor 9000. In this way, service clients can directly access the OceanStor 9000 without the need to change existing DNS settings.
  • Configure the node throughput load balancing policy for clients in both zones.
  • Configure a shared directory for each zone respectively with no quota specified. Nodes can be added to expand storage capacity to adapt to the ever-increasing file volume. New nodes can also be added to the two zones based at a specific ratio to expand the client access capability of each zone based on service loads.
