Case Study :

A Provincial Waterway Bureau in China -- Part 2 of 2

Review :

The Customer. Our case subject is a Chinese Provincial Waterway Bureau. As a branch of the Provincial Department of Transportation, it is responsible for construction, maintenance and administration of all provincial waterways, to assure safe and clear passage. To protect its privacy, our customer has requested that we write this story under a pseudo name. We honor that request and from here on out, will simply refer to it as CSWB, short for Case Study Waterway Bureau. Based on the water systems, CSWB further sets up 16 regional water bureaus and a survey & map center.

Background: Need for Protection and Intelligent Management of Mission-Critical Data. CSWB is at the heart of information exchange for all regional bureaus that are spread across the entire province. As information technologies advance through the years, CSWB absorbs, adopts and progresses along the way, which makes it become increasingly dependent on the smooth operation of its IT infrastructure. Should any of its business sub-systems fail, there would be severe disruption to its daily operation. A primary objective of its new data storage center, therefore, is to assure that the bureau’s mission-critical data stays protected at all times, and is managed intelligently for optimal availability.

Challenge: Guaranteed Business Continuity and Data Protection. CSWB’s business sub-systems are mission-critical applications. The safety of data lays the very foundation for its new data storage center. The project team is tasked with finding a hardware/software solution that is advanced and yet matured, safe and highly reliable, to meet the objectives of data protection and business continuity. To accomplish these key objectives, CSWB needs an effective active-active datacenter solution –- a platform that supports both round-the-clock data protection and availability.

The active-active datacenter’s design must be of high availability (HA), which must be addressed at all levels, including application, host, network, and storage. A sound HA solution 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.
