The SAN-based network is the creation of a separate internal network which is specifically designed to provide high-bandwidth storage device. It allows you to separate the storage systems of servers, and deploy the drives directly to the Fibre Channel network which allows you to create multiple connections between dedicated servers and data storage, and vice versa.
This approach provides the use of storage devices and benefits the traditional networks in the form of improving scalability, availability and performance. Additionally, data backup is no longer affected in the rest of the network, as traffic associated with the backup is performed on a separate SAN network, that is, outside the LAN.
SAN – is a separate, high performance managed network, optimized and concentrated to provide storage, collaborate servers, the operation of data centers and backup devices. It removes the need for traffic to the corporate network that is optimal for the clients-dedicated servers interaction. This technology provides instant access and it is also a technology that does not disable the system to update it. SAN or network data store is the best choice to ensure continuous work on the principle of 24×7.
In accordance with the progress of technology, a new era of networked storage offers solutions that may be suitable for large and small user environments. This new approach also allows the storage and networking solutions to grow with the user, providing the scalability, performance, availability, and centralized management. It must be remembered that the basic unit of data storage is cheaper but the complexity is expensive.
The data center market is boiling. The projects in this area live a moment of expansion, both in corporate and commercial sector to meet the demands of IT, which increased with the growing economy, and also to prepare the ground for cloud. With these requirements, companies are beginning to look at a new alternative for the construction of data centers. Sites are boxed in container, which follow the business where they are in parking facilities, in the sea, dams or in the mountains.
Called Container Data Center (CDC), these new types of data centers are not intended to replace the traditional masonry buildings. They are more to meet specific business needs.
These projects have their targeted audience who need to rapidly expand infrastructure, public companies, oil drilling, civil construction, and mining companies that hold temporary events such as those promoting concerts and sports competitions, among other businesses .
The main advantage of this model, according to the evaluation of consultants in the industry, is the possibility of rapid assembly and disassembly of data centers, since they are mobile and can be transported by truck to anywhere.
Advantages of the data center container
One of the advantages of the CDC is the speed of installation. A data center container can be installed within 60 days. And more importantly, this type of solution reduces energy consumption by over 40% and meets all safety requirements. The CDC are modular and can grow with the needs of customers, adding new boxes, as pieces of lego game, to provide non-stop IT.
The mobile data center can be transported and installed up on the mountain. Even with these advantages, I believe that the CDC will not replace the data centers of bricks, because this solution is an alternative for situations in which companies cannot put the infrastructure in conventional buildings.
According to us, this is a good way to assess the risks and benefits of the cloud computing model.
There are many potential benefits for deploying cloud services, including agility, reduced costs, reduced complexity, greater focus, more innovation and ability to leverage the knowledge and skills of people outside the company.
According to the research, the clue for IT professionals is to perform a thorough analysis, which identifies the benefits that the company hopes to achieve by moving to the cloud. There are still reasons to not to take the path of cloud computing. Among them, the inability to obtain service level agreements that you want, regulatory issues and compliance concerns for disaster recovery and the realization that the cloud might end up saving money.
An accurate cost analysis is particularly complicated, since the user is weighing the cost of capital versus recurrent costs. Customers tend to underestimate the costs of using the cloud, and most companies that intend to move toward a model of professional services contracts to manage the process which increases costs.
There are a number of potential risks. Among them, the executive points out, security, transparency and integration issues. If the company decides to start migrating applications to the cloud, it must do so first by the points and then work your way to the core. The most common applications in these first steps are email, development, productivity applications and web servers.
Another point to keep in mind is that the individual business units have probably moved into software as a service (SaaS), so we recommend that IT executives make concerted effort to get ahead.
