Noroo Paint & Coating Co., Ltd., a paint maker with a 60-year history carried out a project for migrating the numerous business systems, which had accumulated for decades in the server room, to a private cloud. The best part of this project is that servers,
storage and networks are integrated on one rack and 50 or so tasks are residing in individual environments (multi-tenants). This integration of the whole system was possible because Windows Server 2012 and System Center 2012. DIT Co., Ltd., an IT subsidiary
of Noroo Paint & Coating Co., Ltd., who carried out this project, thought that the integration of different tasks in a virtual environment would require the virtualization of the operating systems, networks and storage layers and it would be possible to integrate
different workloads into a single piece of equipment when multi-tenants were possible. The Santa Cloud system DIT developed with their own technology was applied to the project of migrating the cloud system Noroo Paint & Coating Co., Ltd. DIT believed that,
for the cloud environment to create the effect of IT integration, it must be possible to control everything from a single window. Under these standards, Noroo Paint & Coating Co., Ltd. realized the value of System Center 2012. Now centralized control and operation
has become possible over 50 servers, which used to be managed individually, and the maintenance speed and fault response time is now much faster than before.
||As VMWare or Citrix is still concentrating on virtualization itself, they lack many elements in integrated management. If other solutions are adopted, the monitoring and integrated management of storage systems and networks is not
easy. For this reason, it was not easy to find the causes of faults during the operation of the private cloud. So from a realistic point of view, the risks of IT integration may be higher than the benefits.

Noroo Paint & Coating Co., Ltd. has been achieving solid growth since its foundation in 1945, and has become the leading paint maker in Korea. The company planned to relocate its server room at the same time as the construction of the new office building.
It involves not simply moving the equipment, but a broadscale structural change involving the integration of 50 servers onto a single rack. What is often called virtualization technology will be used for IT integration and it will be relocated to the new server
room. Noroo Paint & Coating Co., Ltd. decided to integrate their IT before moving the equipment to the new office building for several reasons.
The first reason was the convenience of the new server room construction and equipment relocation. If the cost of moving over 50 servers, storage devices and network devices one by one, along with the cost of such equipment as the Thermo-Hygrostat and UPS
fit for the size of the equipment, wiring and network cable installation were taken into consideration, the minimum cost was 700-800 million KRW. What mattered was the cost of moving to the same-size server room. The rack space in the old server room was insufficient
for 50 servers and, in consideration for the development of new business systems, a larger server room was necessary. So the construction of a new server room and relocation would have been more costly.
The second reason for IT integration was the difficulties in operations. Most companies, whose computer room is in an ordinary building and not in a dedicated data center, cannot design their own server room and have all the necessary facilities under a
coherent plan looking ahead 10-20 years. In most cases, they establish a rough plan for expansion based on the number of systems they have now and construct the server room from there. As the years go by, the server room will naturally be filled with various
equipment, as well as wires and network cables getting entangled here and there.
Noroo Paint & Coating Co., Ltd. had a similar experience. They add new equipment, such as servers, storage, network and security devices, year after year, then the server room gets filled with equipment, and becomes so crowded that it would be difficult
to know where anything was. Instead of using a single tool for the integrated management of the servers, they were operated individually. So as the server room became more crowded, it became more difficult to quickly respond to faults and operational burdens
increased. “As they were introduced at different times and designed differently, just checking the system status was a big thing,” said Mr. Sung-Min Kim, director of the DIT Technical Research Lab, which is providing IT service for Noroo Paint & Coating Co.,
Ltd.. “Also, to find the cause when the service was down, the server, network and application companies must meet and put their heads together. We had trouble with maintenance.”
The third reason was the belief that resources were not utilized efficiently. Every company with a server room can feel the same way. Even if Noroo Paint & Coating Co., Ltd. predicted that faults were imminent, due to excessive workload for a certain business,
it could not expand the system right away and so the server would go down. Even if other servers have enough CPU or memory resources, these resources were tied up so they could not be used. For a combination of several reasons, Noroo Paint & Coating Co., Ltd.
planned a project to put 50 or so servers (except ERP) on one rack in 2012.
The integration that Noroo Paint & Coating Co., Ltd. had in mind was not a simple virtualization of servers. To be precise, it was to ensure that all layers of the operating systems, networks and storage devices were virtualized and to build a 'private cloud'
environment that could provide a multi-tenants based service. In mid-2012, when the company decided on IT integration, there were technical restrictions to perform all of the tasks using only one piece of equipment. It was not just a physical integration of
servers of the same type, but also required the assurance of multi-tenants to put other types of systems like the web, groupware and document management all in one physical space. It was not easy. There was a good reason for Noroo Paint & Coating Co., Ltd.
to decide to push forward with IT integration, even though they knew
it would be difficult. It recognized the possibility of Windows Server 2012 claiming to be a cloud OS.
“As the appearance of Windows Server 2012 released the restrictions on the number of cores, the limitations on migrating the database server or all important business systems to the virtual environment has gone,” said Mr. Sung-Min Kim, director of the DIT
Technical Research Lab. “Also, as we now have the cloud OS that can accommodate the core component of the cloud system, i.e. virtualization and the integrated management of networks and storage systems, we can meet the actual needs of the company.”
System Center 2012 has made a large contribution for Noroo Paint & Coating Co., Ltd. to take Microsoft's solution in planning the integration of all business systems (except ERP). System Center 2012 has convinced the company
about the private cloud. To find the solution that meets the requirements of Noroo Paint & Coating Co., Ltd., DIT thoroughly reviewed several technologies and arrived at a conclusion. The point was whether the infrastructure, including the operating systems,
storage systems and networks can be managed through a single window. DIT reviewed these two standards, found the answer right away and suggested that Microsoft's solution is the best for Noroo Paint & Coating Co., Ltd.
“As VMWare or Citrix is still concentrating on virtualization itself, they lack many elements in integrated management,” said Mr. Sung-Min Kim, director of the DIT Technical Research Lab. “If other solutions are adopted, the monitoring and integrated management
of storage systems and networks is not easy. For this reason, it was not easy to find the causes of faults during the operation of the private cloud. So from a realistic point of view, the risks of IT integration may be higher than the benefits.” One may think
there is not much to do since everything is on one rack, but the reality is about 50 tasks being performed independently in the complex multi-tenant environment. So DIT thought that, if centralized control is not possible, the difficulty of maintenance would
be ten times greater than before.
Realizing that centralized control is key to the cloud service, Noroo Paint & Coating Co., Ltd. and DIT began the IT integration project based on Windows Server 2012 and System Center 2012. The highlight of this project is to integrate about 50 systems,
including servers, storage systems and networks, on one rack. That single rack became a virtual server room. This system was a package product for the private cloud named "Santa Cloud" developed by DIT. DIT migrated the 50 business systems of Noroo Paint &
Coating Co., Ltd. to the Santa Cloud equipment. These systems were migrated to Hyper-V of Windows Server 2012. Migration was performed as if individual servers were physically moved one by one. The systems were divided into types that require high performance
and a large quantity of resources, like the database server, and types that do not, with workloads allocated to individually separated virtual environments for each of the multi-tenants.
Meanwhile, Noroo Paint & Coating Co., Ltd. completed the IT integration in the second half of 2012 and updated the private cloud management environment to System Center 2012 SPI in early 2013, thus greatly reinforcing the monitoring functions for infrastructure
Convenient equipment migration and a pleasant computer room environment
Having completed IT integration, Noroo Paint & Coating Co., Ltd. relocated their equipment to the new computer room in the new office building in the second half of 2012. If they had to move over 50 servers, they would have conducted a simulation exercise
to check the traffic line, procedures and roles to be very careful. However, as it involved moving only one rack, Noroo Paint & Coating Co., Ltd. had no burden when it came to relocating it to the new server room. Not only the burden of equipment relocation
but also the system shutdown time had been minimized. It is virtually impossible for enterprises without the Disaster Recovery Center to relocate their server room without interruption. The procedure for Noroo Paint & Coating Co., Ltd. was so simple that only
one rack was relocated, network cables were connected and the system was powered on. So the interrupted relocation was not any different from an uninterrupted relocation case. The new server room of Noroo Paint & Coating Co., Ltd. is significantly different
than the old server room where it was hectic with heat and noisy fans. With only one rack besides the ERP server, the new server room is quite pleasant without any heat or noise. The pleasant atmosphere of the new computer room leads to smoother operations.
Managing the integrated environment with one tool
Noroo Paint & Coating Co., Ltd. can check its integrated IT environment at a glance. It secured the visibility of the entire infrastructure. As a result, their level of management is now higher than their previous level when they managed their equipment
physically. Actually, Noroo Paint & Coating Co., Ltd. is realizing the power of the System Center while operating the private cloud. Noroo Paint & Coating Co., Ltd. used to manage their existing infrastructure by manually placing consoles to each system, one
by one. So it took a great deal of time to check server status and if any faults occurred, they had no idea what went wrong and had to call every maintenance company to find the solution. It was routine practice. Now the private cloud has changed the situation.
The System Center operates 50 servers and it is now possible to manage systems, networks and storage devices through a single window. As operations became easier and Microsoft's solution was chosen, Noroo Paint & Coating Co., Ltd. could reduce the burden of
securing professional manpower. Mr. Sung-Min Kim, director of the DIT Technical Research Lab said, “VMWare or Citrix is unfamiliar to most administrators, while the private cloud environment based on the Windows Server and System Center will allow any administrator
to control all the IT infrastructures with simple training.”
Infrastructure without fear of faults
While upgrading its private cloud management environment to System Center 2012 SPI, Noroo Paint & Coating Co., Ltd. raised the fault response level as well. Noroo Paint & Coating Co., Ltd. paid attention to the reinforced monitoring function of System Center
2012 SP1. The company actively accommodated it in its own management environment, thereby raising the level of fault response. “In general, not many enterprises can monitor their IT infrastructure and applications environment in real time,” said Mr. Sung-Min
Kim, director of the DIT Technical Research Lab. “In most computer rooms, they perceive the problem after the system goes down, but Noroo Paint & Coating Co., Ltd. can detect symptoms of abnormalities and respond to them before faults occur.” On the other
hand, Noroo Paint & Coating Co., Ltd. says another effect of the private cloud is that it is now easier to assure business continuity in case a disaster occurs. Noroo Paint & Coating Co., Ltd. implemented both disk and tape backup for the servers. As it had
50 servers, they conducted daily backup and weekly backup according to the order of importance. After the implementation of the private cloud, the data of all 50 servers is backed up every day, and the company is considering using the public cloud for remote
backup as well.
