Basic Data Center Concept
A data center is a physical facility that is used to place critical applications along with their data. Fundamentally, the data center design is based on computer networks and storage resources that allow the data center (DC) to share applications and data. Modern business today is very dependent on applications, services, and data located in the data center. As a result, the data center becomes a critical asset because it is used in daily business operations.
Today's modern data center is different from DC a few years ago. The infrastructure has shifted from a traditional on-premises physical server presence to a virtualized infrastructure environment that supports applications and workloads distributed across the physical infrastructure and including the cloud network environment.
Currently, modern DCs are scattered in various places, where data and applications are located. Crossing public or private cloud networks to the network edge via mobile or embedded computing. This is an environment that is constantly changing, DC must follow the interests of users and applications.
Why Are Data Centers Important for Business?
In today's modern enterprise or business organization, data centers are designed to support business applications and activities that include, among others:
a. Email and file sharing
b. Productivity apps
c. Applications for customer relations management and enterprise resources planning
d. Big data
e. Artificial Intelligence
f. Communication and collaboration services
g. Data Center Core Components
Datacenter design includes the existence of applications such as routers, switches, firewalls, storage systems, servers, and application delivery controllers. Because this component stores and manages critical business data and applications. Security is a critical part of data center design. Together they facilitate:
Computer network infrastructure. Connecting servers (physical or virtual), data center services, storage, and external connectivity to end-user locations.
Storage infrastructure. Data is the fuel of the modern data center. Storage is used to store this valuable commodity.
Computing resources. Applications are data center engines. This server provides processing capabilities, memory, local storage, and network connectivity that can control applications.
How Do Data Centers Work?
The data center is not a single object, but a combination of various elements. At a minimum, the data center functions as a storage area for all IT devices. Among others: servers, routers, switches, firewalls, storage, cabling, racks that are organized and connected. In addition, there are other infrastructures such as buildings, distribution of electricity, electrical equipment, cooling systems, as well as support from network carriers for WAN connections. All of them work together so that the data center can operate and provide the necessary services.
Standard in Data Center
The standard commonly used for data center infrastructure is ANSI/TIA-942 and includes certification. Ensure that the data center complies with one of the 4 categories of the data center tier that assesses the level of redundancy and fault tolerance.
Data Center Type
There are several types of data centers and service models today. The classification depends on whether it is owned by one or more organizations, how it can match the topology of other data centers, the technology used for computing and storage, and its energy efficiency.
Data Center Architecture and Design
Even though any location or space can be used as a data center. Datacenter design and implementation must be carried out with great care. Apart from basic issues such as fees and taxes. So the location must be selected based on several criteria, such as geographical location, seismic stability, access to roads and airports or terminals, availability of electrical energy and telecommunications, even including the socio-political conditions where the data center will be built.
After the location problem has been resolved, the data architecture can be designed with attention to the mechanical and electrical infrastructure aspects as well as the composition and layout of IT equipment. All of these issues must be addressed with guidance on aspects of efficiency and the fulfillment of the Tier targets to be achieved.
Energy Efficiency and Consumption
A data center is an infrastructure that is greedy in terms of energy consumption. The higher the IT service capacity and the Tier target, the consumption will be calculated in megawatts. Even a data center containing 60 full 42 U racks with a Tier 3 level can consume 2 megawatts of electricity.
Therefore, the layout design and the placement of the racks along with the cooling are the keys to saving electricity. Because the electricity consumption of the device and cooling absorbs 70% of the total electricity provided. The data center layout with the Hot Aisle / Cold Aisle concept is the key to electrical energy efficiency. In addition, of course, the use of server and network devices that save electricity.
That's why big players like Google, Microsoft, Alibaba, etc. prefer to put their DC in cold climate countries. Because DC operating costs in tropical countries are more expensive than in cold climates because of the large cooling system requirements. However, government regulations forced them to finally set up a data center in Indonesia.
