Case Study :
A Prominent TV Station in China -- Part 2 of 2

Review

The Customer. Our case subject is a prominent China-based media conglomerate, which actively serves its national audience base with broadcast content over television, newspaper, Internet and new media. To protect its privacy, our customer has requested that we write this story under a disguised name. We honor that request and from here on out, will simply refer to it as CSTV, short for Case Study Television Station.

Cloud Computing Technology in the TV Broadcasting Industry. To view cloud computing at the 30,000FT level, it is simply the centralization of traditional computing and storage technologies through networking and management, which forms a public or private resource pool that offers on-demand services to users. Applying this exact concept, the television industry should streamline its supporting IT infrastructure, by integration of computing resources through virtualization technology, combined with FC (Fibre Channel) and SAN (Storage Area Network) technologies; which would then provide the base for improving its editing and production systems to achieve better resource utilization, higher availability, more stability and structural flexibility.

High-Availability Access and Protection for Digital TV Production Operations. The system’s high availability (HA) must be addressed at all levels, including application, host, network, and storage. A sound HA system should deploy software-clustered hosts and virtual host technology, to ensure the availability of hosts and continuity of applications; as well as fully redundant SAN switches to ensure the availability of network paths. In addition, the storage must be enabled to deliver equivalent availability, so that an end-to-end redundancy from hosts through network to storage may be achieved.

While the applications of host virtualization and networking technologies for HA purpose have largely reached maturity, the same could not be said about storage HA. Therefore selecting a best-fit HA SAN architecture was identified as one of the key requirements for the project team.
