DataCenter

A datacenter is a set of servers, communication/security infrastructure, and electronic equipment to provide, maintain and support network services (Internet/Intranet/Extranet). Organizations, companies, and individuals can launch their network-based information and services on the Internet (intranet/extranet) by using the services provided by the website data center. A data center can act as a processing center, data storage center, data collection center, or all of these, depending on the type of application it is defined for.

more details

A data center is a building, a dedicated space in a building, or a group of buildings, used to house computers and related systems. Components such as telecommunications and storage systems.
Because IT operations are critical to business continuity, they generally include additional or backup components and infrastructure for power supplies, data communication connections, environmental controls (such as air conditioning, fire suppression), and various security devices. A large data center is an industrial-scale operation that consumes as much electricity as a small city.

 

Date

The data center has its roots in the large computer rooms of the 1940s, characterized by ENIAC, one of the first examples of a data center. That required a lot of cables to connect all the components, and methods were devised to accommodate and organize them, such as standard racks for mounting equipment, raised floors, and cable trays (mounted overhead or under the raised bed). A single mainframe required a lot of power and had to be cooled to prevent overheating. Security became important – computers were expensive and often used for military purposes.

The availability of inexpensive network equipment and new standards for structured network cabling made it possible to use a hierarchical design that housed servers in a specific room within the company. As applied to specially designed computer rooms, the term dataCenter began to gain general recognition.

The term cloud data center (CDC) is used. Data centers are usually expensive to build and maintain. Increasingly, the division of these terms has almost disappeared, and they are being merged into the time “data center.”

Requirements for modern data centers

Datacenter renovations and transformations increase performance and energy efficiency.

Information security is also a concern, so a data center must provide a secure environment that minimizes the possibility of security breaches. Therefore, a data center must maintain high standards to ensure the integrity and performance of its host computer environment.

The industry research firm International Data Corporation (IDC) considers the average age of a data center to be nine years. Gartner, another research firm, says data centers over seven years are obsolete. Data growth (163 zettabytes by 2025) is one of the factors driving the need for data centers to modernize.

The focus on modernization is nothing new:

Concerns about obsolete equipment were criticized in 2007, and 2011 the Uptime Institute was concerned about the age of existing equipment. Staff age: “Data center staff age faster than equipment.

Compliance with data center standards
Telecommunication infrastructure standard for datacenter

The Communications Industry Association specifies minimum telecommunications infrastructure requirements for data centers and computer rooms, including single-tenant enterprise and multi-tenant Internet hosting data centers. The topology proposed in this document is intended to apply to any size data center.

Telcordia GR-3160, NEBS Requirements for Telecommunications Data Center Equipment and Spaces, provides guidelines for data center spaces in telecommunications networks and environmental requirements for equipment intended to be installed in those spaces. Telcordia and industry representatives jointly developed these standards. They may apply to data center spaces that house data processing or information technology (IT) equipment.

This equipment may be used for:

• Setting up and managing the telecommunications network of a telecommunications company
• Deliver data center-based applications directly to operator customers
• Provide hosted applications for third parties to provide services to your customers
• Offer a combination of these and similar data center applications

DataCenter transformation

Data center transformation is a step-by-step approach through integrated projects carried out over time. This differs from the traditional data center upgrade approach, which takes a serial and siled approach. Typical tasks in a data center transformation initiative include standardization/consolidation, virtualization, automation, and security.

Standardization/Consolidation:

Reducing the number of data centers and avoiding server expansion (both physical and virtual) often involves replacing old data center equipment, and standardization helps.

Virtualization:

Reduces capital and operating costs and reduces energy consumption. Virtual desktops can be hosted in data centers and rented on a subscription basis. Investment bank Lazard Capital Markets estimated in 2008 that 48% of enterprise operations would be virtualized by 2012.

Automation:

Automated tasks such as provisioning, configuration, modification, release management, and compliance are needed, not just when dealing with less skilled IT workers.

Making safety:

The protection of virtual systems is integrated with the security of the existing physical infrastructure.

Telcordia Technologies, a subsidiary of Ericsson, developed the high-level standards guide GR-2930.

Although the first high-floor computer rooms were built by IBM in 1956, and they’ve “been around since the 1960s,” it wasn’t until the 1970s that computer centers allowed cool air in this way—more efficient circulation.

The first purpose of the raised floor was to allow access to wiring.

light off

A “lights off” data center,[37] also known as a dark or dark data center, is a data center that, ideally, has eliminated the need for direct personnel access except in extreme circumstances.

Noise levels

Local authorities generally prefer noise levels in data centers to be “10dB less than the nighttime background noise level in the nearest residential area”.

OSHA regulations

OSHA regulations require monitoring of noise levels in data centers if noise exceeds 85 decibels.
The average noise level in the server areas of a data center may reach 92-96 dB(A).

Residents who live near the data centers have described the noise as “loud 24/7” and said: “It’s like an airplane engine running on a tarmac. .. except that the plane is idling and never leaving.”

External sources of noise include HVAC equipment and power generators.

 

 

Datacenter levels

The two organizations in the United States that publish data center standards are the Telecommunications Industry Association (TIA) and the Uptime Institute.
International standards EN50600 and ISO22237 Information technology – Data center facilities and infrastructure

Class 1 single-path solution
Class 2 single path with redundancy solution
Multiple Class 3 courses provide a simultaneous repair/operation solution
Class 4 multipathing provides a fault-tolerant solution (except during maintenance).

Telecommunications Industry Association

The Telecommunications Industry Association’s TIA-942 standard for data centers, published in 2005 and updated four times since then, defined four levels of infrastructure.

Rank 1 – A server room, following basic instructions
Rated-2 – Additional components are additional vital components
Rank 3 – Concurrently maintainable, able to maintain any part of the distribution path or any single piece of equipment without interrupting the operation of the data center.
Rank 4 – Fault tolerance, capable of handling one fault at a time in any part of the distribution path or equipment without interrupting data center operations.

Uptime Institute – Data Center Tier Classification Standard
The Uptime Institute standard defines four tiers:

Row I

Vital capacity and should include a UPS (uninterruptible power supply).
Tier II – Adds extra ability and extra power and cooling. Level III – Concurrently maintainable and ensures that any component can be removed from service without affecting production.

Row IV – FAULT Tolerant

allows any production capacity to be isolated from failure.
The fifth rank is trademarked by Switch (the company), which used the row to define The Citadel, the largest datacenter in the world.

Data center design

Data center design has been evolving for decades in various directions, including new construction, large and small, and the creative reuse of existing facilities, such as abandoned retail space, old salt mines, and wartime bunkers.

By 2016, the number of data centers had grown to more than 3 million across the United States and more than tripled worldwide.

Local building codes may govern minimum ceiling heights and other parameters.

 

Some considerations in the design of datacenters are:

• Size – one room of a building, one or more floors, or the whole building,
• Capacity – Can hold up to 1000 servers or more
• Other considerations – space, power, cooling, and costs in the data center.
• Mechanical Engineering Infrastructure – Heating, Ventilation, and Air Conditioning (HVAC); Dehumidification and dehumidification equipment; Pressure.
• Electrical engineering infrastructure design – Urban service planning. Distribution, switching, and bypassing of power sources; uninterruptible power supply systems (UPS); and more.

Design criteria and Trade-offsAvailability expectations: The costs of avoiding downtime should not exceed the price.

• Choosing the site (for example, the availability of electricity is the most difficult.)
• High Availability: There are various metrics for measuring data availability, which results from the data center being available more than 95% of the time uploaded, with the top of the scale
• counting the number of “no” after “99%”.
• Modularity and flexibility: Modularity and flexibility are vital elements that allow a data center to grow and change over time.
• Environmental control
• Electric power
• Low-voltage cable routing
• Airflow: Corridor containment
• Fire protection
• security

energy consumption

• Emission of greenhouse gases
• Energy efficiency and overhead
• Analysis of energy consumption and projects
• Power and cooling analysis
• Energy efficiency analysis
• Computational
• Analysis of fluid dynamics (CFD).
• Thermal zone mapping
• Green data centers
• Energy reuse

Dynamic infrastructure

Dynamic infrastructure provides the ability to intelligently, automatically, and securely move workloads across the data center anytime, anywhere, for migration, provisioning, improving performance, or creating co-location facilities. It also facilitates routine maintenance on physical or virtual systems while minimizing downtime.

Additional benefits include

Reduce costs
Facilitate business continuity and high availability
Enabling cloud and network computing

Today, communication in data centers is often based on networks that run the Internet Protocol Suite.

 

Software/data backup-exclusive options for data backup include:
On-site :

It is on traditional premises, and a significant advantage is immediate availability.

Off-site

Off-site backup storage

Data backup techniques include having an encrypted copy of the data off-site.

The methods used to transfer data are:

Ask the client to write the data to a physical medium such as magnetic tape and then transfer the video to another location.
Transfer data directly to another site during backup using appropriate links. Upload data “to the cloud.”

Several major hardware vendors have developed mobile/modular solutions for rapid deployment or disaster recovery that can be installed and deployed.

It should be noted that there are pervasive explanations and cases about Data Centers. Unfortunately, paying for all the articles and materials in this regard is impossible, so we did our best to compress the actual headlines, and I hope you enjoy it. Thanks 🙂
