A data center is a facility where a centralized organization shares IT operations and equipment, as well as a physical location where data is recorded and calculated. Businesses and other organizations use these facilities to store, disseminate, process and organize large amounts of data. Data centers are able to communicate between multiple sites on-premises and in the cloud. Key components of a data center design include switches, routers, storage systems, servers, firewalls, and application delivery controllers. Therefore, the security and reliability of the data center and its information is a top priority for any organization.
Why data centers are important?
Most businesses need to store data, and they store data on servers, which are like specialized computers connected to the business’s local network, usually to the Internet. However, as businesses and their needs grow, more servers and space are required. So at this time, a data center is needed to store the data in a secure facility.
The Role of the Data Center
A data center is an integral part of an enterprise, designed to support business applications and provide: data storage, management, backup and recovery; large e-commerce transactions; big data, machine learning and artificial intelligence services.
Virtually every company and government entity sets up and maintains its own data center, or has access to someone else’s data center. Renting servers at co-location facilities, using data center services run by other parties, and using public cloud-based services from other organizations are also options.
Types of Data Centers
- Enterprise data centers
- Managed services data centers
- Colocation data centers
- Cloud data centers
The Standards for Data Center
- Tier 1 – It is the most basic type of data center and needs to include a UPS.
- Tier 2 – System, power and cooling redundancy is required.
- Tier 3 – Provides partial fault tolerance, allowing any production capacity to be isolated from any type of failure.
- Tier 4 – Need to ensure that any component can stop service without affecting production.
The Core Components of a Data Center
Key components of a data center design include switches, routers, storage systems, servers, firewalls, and application delivery controllers.
Infrastructure: Space available for IT equipment, providing 24/7 access to information, keeping equipment within a specific temperature/humidity range. This connects servers, data center services, storage, and external connections to end-user locations.
Core components: IT hardware and software, as well as data and application storage. Storage systems, servers, network infrastructure such as switches, routers, and firewalls, cabling, and physical racks used to arrange and integrate IT equipment are all examples.
Support infrastructure: Power distribution and backup generators; uninterruptible power supplies (UPS); ventilation and data center cooling systems such as computer room air conditioning, heating, ventilation and air conditioning systems, exhaust systems; physical security systems, biometric and video surveillance systems; operations personnel, Personnel who operate and maintain IT and infrastructure equipment 24/7.
