Data Center Design Report
Data centers design is a popular topic in the network’s field. There is a possibility that data centers may be in high demand in an institution with a capacity as big as 15,000 people. Every company has its own data center in which they use different layered devices. Switch router firewall MPLS among others. It is well known that a data center maybe considered as the lifeblood of any organization dealing with huge volumes of data. Hence, professionals working in a data center should have a good understanding of the hardware and design principles that should be used in such a facility. In data center, different operating systems and processors are used.
When the internet users use the IS platforms or other online medium the data flow is also increased with the usage not everything can be stored on transactional databases for long periods of time. So the information is backed up to data centers. So it is important that data should be captured the data center. In a data center, there are a variety of machines running in the rack and connected with different cables present that store the information. These machines are hardware devices.
A data centre can be built in any location but preferably cold areas to keep the hardware cooled as there are multiple machines engaged in the collection, storing, processing and distribution of massive amounts of data. Data centres collect the data, process the queries, process the data, give the outputs and distribute it. Usually, data centres are the most critical facilities in big companies, institutions, and organizations since they aid in ensuring the effectiveness of daily operations. One important thing to note is that data centres should maintain a high level of security and reliability is that the security and reliability of information making it a top priority for the institution. Security is necessary because data must be secured and protected at all times. Data can be accessed by authorized personnel’s and no unauthorized users are allowed whatsoever.
Components of Data Center
A bunch of servers are connected through the network to run a complex application and give the output against the action. Cooling system to manage the heat released by the machine and maintain room temperature. In data, the Center has the proper Ventilation system which ensures the optimal air-flow. Here is the security is the most important, prevent unauthorized users. Use Security cameras for physical checking which is accessing your data centre room and also implementing the firewalls and many other security measures to revoke the unauthorized users.
Power distribution & backup units (Generator, batteries etc.) for smooth execution using power supply units. Having backup systems make sure that the data centre is always running on the maximum uptime. In backups not necessary to build in the same location you make it in other locations where if youyou sever collapses then you can retrieve your data from the the backup server and managemanage it.
Servers and Racks
The primary objective of establishing a data centrecentre is to host the servers required to support students’ information and websites as well as ensure proper management of various infrastructures. Servers are designed in ranks which may be assigned a particular configuration within the managed hosting that aids improve cooling.
A rack server is designed and installed in a framework referred to as a rack. There are numerous mounting slots known as bays that help manage a given hardware unit and they are fastened with screws. There may be several servers stacked together one over the other in a single rack and this unites network resources as well as reducing the required floor space. Cabling between network elements is significantly reduced. A cooling system is also necessary to ensure that unnecessary rise in temperatures is controlled. Such a situation occurs when multiple power-dissipating components are placed together in a limited space.
Power
Every data centrecentre requires a reliable source of power to make sure that all components are running without failure. In case there is redundant electricity a backup generator must bea backup generator must be available to provide power when there the centre experiences power disruptions. Hence, uninterruptible energy supply (UPS) should be installed to maintain a consistent running during a power outage. Moreover, a backup power source compensates for voltage fluctuations and frequency to ensure that sensitive electronic components are protected. Besides, the power in the data-centre has four phases which that comes from the main power supply going through the transformer then enters to the data-center (UBS) then enters into servers and rocks.
Network Layout
Network data-center is considered as a computer system that is connected to an internet connection to ease access of various information technology solutions. In addition, there are systems of network switches that are distributed among servers. There may be one or more switches in every rack.
Security of the Data Center
Security is the most important in the data center. Security Cameras must be installed in building which check on the unauthorized persons. Only authorized person access the data center room and check the racks and machines. And revoke the unauthorized persons. Because which not don’t have the knowhow that will do henky phenky with your system. Take the security measures in which you can use the different technology in which retina scanner and hand sized fingerprint scanning device. By the way only allowed person can access and enhance the security. Security of data is varied based on the data center available. In most cases experts support redundant use of data centers (Barroso & Hölzle, 2009). Also, they promote versatile power sources and multiple environmental handles. Having a reliable data center demands that enough security should be enhanced and it is reliant on the network virtualization level used.
Connectivity
Mostly of the data centers connected through internet which provide the sevices to the users. Now data center provide the services in which companies no need to make the serately data centers for the company.
Fire Protection
As we know that in data center have millions of dollars of equipment in one building and producing heat continuously so have the risk of burning so we need the proper measurement for the burning effect in which use the cooling systems which cool down the systems.
Power Continuity
Must have to install the backups in the data center which provide the continuously services. It is a most important part of the data center. In case of disaster we maintain the backups because if any issue face or lost the data then we have backup and can retrieve data from the backup and must be located in any other place.
The Monitoring Systems
A data center should have enough monitoring systems to be used by operators in managing a working environment. Energy consumption is monitored using the monitoring systems by observing things such as temperature and relative humidity (Gupta et al., 2011). In addition, keeping watch the network closet and enterprise level data centers inclusive of environmental monitoring solutions.
Configure alert notices to get Email, SMSs, or voice call alerts to inform the employee when something turns out badly. Switch particular outlets on or off on caution or physically through the GUI.
Storage
In a data center, storage is a common title that refers to the tools, technologies, and other infrastructures inside a data center. Storage of data primarily relate to devices, gadgets, and other storage methods that make storing of data in a data center possible. There are various ways through which information in a data center may be stored. They include hard disk drives, tapes, and other internal and external forms of storage (Barroso et al., 2013). Secondly, storage and backup management software utilities may be used in the maintenance of data. External storage facilities like cloud or remote storage are a reliable way to store information in a data center and should be utilized. Storage area networks (SAN), network attached storage (NAS), among other may also be used in a data center as alternative forms of data storage.
Raised Flooring
A raised floor is a data center development in which a marginally higher floor is built over the building’s unique solid section. It leaves an open space that is made between the two cooling systems. In addition, a raised floor is built and it is intended to accommodate the expected data heap from the data center hardware. Besides that, the fact that the raised floor display was previously the standard method to convey control and give availability, more up to date configuration models move the cables overhead and utilize the space under the raised floor for the cooling funnels or wind stream for hot aisle.
Data center Services
Data center services (DCS) refers to the services that are performed in the facility which are not limited to creating, implementing or maintaining a data center, also to optimize what the data center has been established for to make a different side of the performance that related to the institution. Moreover, though it is a very broad term it includes several sorts of services that may aid planners in brainstorming around how to establish data center. Additionally, there are many different services that the data center provides in an organization with high efficiency.
Building a data center needs a considerable amount of research about an organization’s broader IT infrastructure. At the start, organizers need to consider what sorts of information are profitable to the business, what estimated volume of data storage will be required, and how data from a wide cluster of sources can stream into a focal storehouse easily and be taken care of reliably (Pan, 2008). Managers will regularly need to modify or enhance particular procedures for better performance. Here, data center services can assist with improving data backup or data recovery, the stream of information to singular employees or students in the institution, and the utilization of accumulated huge information to encourage use of technology to investigate the future of the institution.
Computer Connectivity
Network-topology may be understood as a network components’ pattern. It is a unified pattern of different network components which may be physical, a mapping appliance configuration which map the way that data is distributed keeping in mind that the requirements are to ensure that there is proper connection throughout the systems. There are various variant topologies but they are not strict and that shows that any of them may be consolidated. Nevertheless, every topology has a different standard and might utilize diverse hardware techniques so they cannot be interchanged.
In network-topology, a physical-topology relates to a particular physical design. Also, a logical-topology shows how data is controlled within the network without necessarily looking its physical topology. Moreover, a Local Area Network (LAN) is a decent instance of a network that shows both an intelligent and physical topology. In the local area network, there is a connection among all the terminals that are joined together. The physical topology is taken as mapping for this form of interconnection, while the logical topology of the network is determined by the way through which data flows.
Star-Topology-Network
Star-topology relates to a network where every single piece of the network is connected to the central node, (which has another name called hub or switch). The connectivity of these network parts to the central element appears to be represented in a form similar to a star. Moreover, there are several advantages that are associated with star-topology. They include the fact that; it has a centralized management of the network, it uses a central computer, hub, or switch and it is easy to add several computers within the network. Moreover, if one computer on the network fails, the rest of the network may still continue to function the right way.
The star-topology may be recommended as the main connectivity for the data center as the perfect way since it can be utilized in several ways. That is because it is easy to replace, add, or configure nodes, per Nodes are inherently divided by the link that attaches it to the centralized device. In addition, by star-topology can isolation also prevents any non-centralized failure from harming the network and does not let any interruptions to the network while connecting or removing machines. Besides that, Star topology makes it impossible for data packets to pass through various nodes. It makes sure that at most, three devices and 2 links are used in all communications involving at least two devices at a time.
