It equipment bodyguard APC helps Ningbo Grand Champs Terminal IT system

Ningbo Grand Pavilion Merchants International Terminal Co., Ltd. (hereinafter referred to as the Grand Champs Pier) is located in the Ningbo, Zhejiang Province, located in the main pavilion, the Chinese coastline, the south wing of the Yangtze River Delta, the Changjiang Gold coastline of the intersection, the location is superior, domestic and foreign shipping to enter the Yangtze River delta

Project description

As an important part of Port business, the informatization degree of Wharf container operation plays a vital role in speeding up port travel turnover, increasing freight speed and reducing overall transportation cost. The container operation involves a series of links, such as ship entering and exiting port, container handling, container transportation, large loading and unloading machinery control, yard planning and Operation schedule control. From a container port, to the boat, transport, drop-yard storage, and eventually transport to the ship, accompanied by the entire business process generated data up to dozens of, and the daily need to deal with more than tens of thousands of data records.

With 3.54 billion RMB invested in the terminal project, only 7 of the maintenance staff of IT systems, IT systems must reach 99.9999% (so-called "5 9") availability standards to protect the business. "If the core production IT system is paralyzed, the container cannot enter the gate, the collection card (the truck that ships the container) will line up and all the terminals will stop loading and unloading." The economic loss per hour may reach hundreds of or even tens of millions of, and more serious is the loss of credibility, will lose customers, the ship no longer dock the Grand Pavilion Pier. Now the wharf competition is strong, each wharf relies on better management system to win the households, if which terminal system has the total problem, the customer will not choose this dock again. Ningzhiyong, vice minister of the Grand Champs Pier Engineering, explained to reporters how important IT system "5 9" availability was to them.

In this case, the newly completed data center room has become the backbone of the entire system. According to Zhang Yi, an IT engineer at the Champs Quay Engineering department, the establishment of the data center cost them a lot of thought. One of the server selection took 7 months, not only to the surrounding dock, port for the search, but also with a variety of experts to discuss the selection problem, light related to a thick stack of data. In the end, the Grand Champs Quay chose HP 9000 server and Cisco network Equipment, and chose the dock-specific operating system of China merchants ' system as software. "It can be said that in order to ensure the continuous operation of the terminal business, all of these software hardware is based on the highest standards of choice." "Zhang Yi talked.

However, after the server and network devices have been selected, a new problem emerges in the Ningzhiyong brain---the best devices stack together to show that the system is highly usable?

High availability device = high availability system?

"We have a very good server, very good network equipment, these are not necessarily guarantee that our system can achieve the required 99.999% stability?" In an interview with reporters, Ningzhiyong to reporters that they have thought about many questions.

"Finally, we found that there is a big gap between device availability and system availability, and there are a number of key points to consider in the system environment." "Ningzhiyong told reporters. These key points, is the network key physical infrastructure---ncpi, that is, including power supply, cabinets, refrigeration, services, management and other subsystems, supporting the upper-level IT system operation of the infrastructure.

NCPI is not an isolated view of the various parts of the computer room, but as a unified whole, the ultimate goal is to focus on the power, air-conditioning, monitoring and other key subsystems of the construction of it micro-environment. If the entire network environment as a water bucket, UPS has become the tallest plank. But to improve the availability of the overall system, that is, to expand the entire barrel of water, distribution links, cable wiring, room heat management, rack heat management, as well as the entire system management and other boards must be increased, but also to strengthen the coordination between the Board of the degree.

"You might not have imagined that we had spent two months in the selection of physical infrastructure in these rooms." "Zhang Yi told reporters.

Previously, in the Grand Pavilion Wharf bidding process in a total of nearly 10 suppliers to come to tender, they are focused on ups, cabinets, air-conditioning, wiring and other fields. "It can be said that each supplier is a related field of experts, but if these things together, can play a 1+1=2, or even more than 2 effect?" Moreover, our future IT job establishment only 7 people, management work they can cope with it? "In response to these problems, the leadership of the Grand Champs Pier has been discussed many times."

Separate purchase of different products to combine, the initial cost of investment than to buy a package of solutions cheaper, but, due to the staffing and security of the system, after several discussions, the Grand Champs Terminal has opted for the Apc-infrastruxure (Infineon Integrated System) based on NCPI standard.

Overall Solution simplification Management

As an integrated system of racks, refrigeration, power supply, management and maintenance, Infrastruxure has ensured high power supply reliability through n+1 redundancy structure, and has avoided many unreliable factors through the design of integrated power infrastructure, thus greatly improving the overall usability of the system. At the same time, because of the modular and pre-designed standard components, Infrastruxure integrates basic power supplies and management components into a flexible, easy-to-use standard module, helping to reduce complex power installation processes, ensuring high reliability, manageability, and serviceability.

The integration of the solution to make the management of the room more convenient, it is understood that the current computer room operation and maintenance personnel only 1, and not full-time in this, but also responsible for some weak project work. According to Mr. Jung Myung Seok, the engineer of the management room, he doesn't have to go into the computer room at all, and all the maintenance work is done remotely. Speaking, he opened the remote monitoring screen, for the reporter made a further demonstration.

Due to the choice of integrated solutions, the temperature of the room, humidity, cabinet temperature, UPS status, and even the load of each socket in the cabinet is clearly/shown in the management software. If there is a problem, the system will also notify the administrator the first time by e-mail.

"In the past, we always have to work overtime in the computer room, now, a few people with permission to remote monitoring through the browser at home, for us to reduce a lot of work." "Zhang Yi talked.

Dual System Guarantee "5 9"

Another major feature of the Grand Pavilion Terminal is the complete use of the two-way design from end to end, which fully protects the power supply of IT systems. Dual power supply module design greatly improve the redundancy of the system, the normal state, two power supply modules to play a load-balanced effect, and when one module is damaged, the other one to bear all the work.

And this, is also in many user's room inside have not seen. "Many users connect two power modules to the same ups, and once the UPS is in trouble, the system will be paralyzed," he said. "Zhang Yi told reporters.

In the room of the Grand Pavilion Pier, the reporter saw two sets of UPS distribution system, connected to the server's two power modules, to achieve a "thorough" of the two inputs, will likely be caused by the outage to minimize the loss, while greatly reducing the impact of precision it instruments. It is understood that with the current configuration, in the absence of air-conditioning, the computer room can run two hours. At the same time, the pier is also equipped with a third power input, by its air-conditioning power supply, the main Pavilion dock room can be maintained for two hours of operation.

Zhang Yi also pleased to tell reporters: "The system on the line, there has not been any problems, has maintained a very stable state, I believe it will be able to achieve ' 5 9 ', or even higher system availability." ”
