Data Centre Guidance

Data centres have been around for quite some time, allowing individuals to have the ability to connect and bring technology to a reality.  Having had the chance to work in this industry over the past few years I know about the extensive job opportunities it brings with it. So where do we go from here? Let's start with strategy.

Data centres are using technology to build hardware goods as well as collecting information, enforcing better decisions and acting on them correctly. As technology progresses, digital data grows, allowing individuals working in IT to apply their excellence and expertise to multiple data centres, leading to more efficiency and lower costs. 

Some of the duties and tasks may differ depending on the data centre and location. Some data centres have quite simple processes such as storage for data backup and execution. Other centres act as a connection to each other, where different parts of equipment will be requested to be sent between different centres. Meanwhile others will optimise for individual companies they work with providing suitable equipment.

This blog paints a picture regarding some of the key functions of a data centre and the type of roles they’re looking to hire for. If you’re new to the market, a computer enthusiast and looking for new opportunities, keep reading. We might need to connect soon.


Why are data centres important?

Let’s start with the big ‘why’. Large companies accumulate an immense amount of data that require many servers and enormous storage space to hold this data. Maintenance brings an increase in high energy and at times simple servers cannot cope with the flow of data. 

That’s where DC’s have become useful, locations of data centres are monitored therefore the data stored is secure. Temperature is controlled at all times to avoid servers overheating and in case of an emergency the power supply ensures all data stored is backed up and the risk of server failure is reduced. 


How data centers work?

Large organisations operate globally on data centres facilities to deliver the best service to their consumers. A lot of work goes into the back-end process before parts or products are delivered and serviced to multiple locations and companies who are in need of technology starting from as small as components for PC’s and laptops to servers ending with programming and cloud data.  

Since COVID19 more businesses moved to a digital sphere with the need to have effective equipment enabling almost half of the population to work comfortably  from home. The organisations and users were in desperate need to rely on data centre workers to act fast on providing the best high tech service with network connectors allowing end-to-end users to gain rapid access to information working remotely matching up the speed they had in the office. 

At that crucial time when the remote working environment was rapidly growing, Data Centers became more relevant than ever thus increasing the large scale of head-count over the last 2 years of hires. 

What is a server? It is a high functioning and powered machine that pulls and pushes data between itself and clients. This device is designed to process requests from other devices and programmes to deliver data via internet or local network. 


Data centres in Ireland

In Ireland currently there are about 70 data centres out of which 65 are up and running in Dublin. Tech companies such as Amazon, Facebook, Microsoft and Google hold the most facilities. Of course let’s not forget some of the smaller companies who work in conjunction with each other, and provide servers and equipment to each other. 

“There is more to data centres than meets the eye! They are the heart of a digital transformation movement!”

Globally the internet traffic has increased by 40% since 2020, doubling internet users and traffic by 30% per year. Data centres providing us with a service has given people the privilege to work from anywhere in the world and work-from-home.


Now that we know the why and how, let’s dive into the who.

When considering a data centre role an individual needs to have knowledge of computer/server hardware, networking, cabling/wiring, systems and electrical/mechanical engineering wisdom.
Of course some technology driven enthusiasts may only hold a passion not experience for the above and this is where GemPool comes in. We have seen tech-passionate individuals who have massively progressed their career from just building PC’s to obtaining certificates allowing them to up-skill to IT Technicians.

Key traits that are considered essential for a  successful data centre candidate  are collaboration, willingness to take ownership, passion for growing knowledge, positive and creative attitude.

Data centres look for discipline and integrity in the workplace and lastly meeting stands and completion of the workflows i.e projects. 

Standards & process workflows

Traditionally data centres provide end-to -end lifecycle of data centre operations including:

  • Rack Insulation/ Design and deployment 
  • Management and troubleshooting
  • Decommissioning of components 
  • Maintenance of mechanical and electrical machinery 
  • Electrical and mechanical engineering
  • Security & supply-chain management 

A significant proportion however takes place at the logical level with workflows, system design, engineering and design architecture of the IT environment.

With the workflows integrating with each other, opportunity opens for professionals to apply their expertise to multiple data centres and teams which leads to more efficiency and lower cost.


Components of operation 

Data centre operations also known as “DCO” can refer to the process, systems and workflows used to operate a DCO facility.

In IT data centres it includes several areas: Maintenance and procurement of the infrastructure in the data centre. IT systems and security such as hands-on hardware work and troubleshooting. Data centre management which includes warehousing - equipment being requested from teams and sent out to different locations.

Server hardware includes technical components that are built into individual computers, through a high performance of a CPU.

Network components, devices such as switches, firewalls and routers are required to activate the operation and connection of network components. 


Let's take a look at inventory 

Hardware inventory is a discovery of the physical servers and infrastructure equipment which needs to be replaced. This can include data centre network servers, PC’s routers, firewalls, printers, modems, uninterruptible power supplies, backup devices and the list goes on. For each piece of equipment however you will need to gather detailed inventory such as; CPU, memory and storage along with adaptors. 

The above may surprise you but  all the key components and equipment are critical to make ancient servers still serve their purpose which you may not have realised contributes to sustainability!


Benefits working with recruiters 

working with an IT recruiter for your job search

There are a number of key advantages putting your faith into a recruiter, here's a few:

  • Tailored search: recruiters understand the candidates needs, wants, skills, experience and career goals and use that to match them up with the job opportunity that aligns with their needs, interests and qualifications. In a perfect match maker. 
  • Access to hidden job opportunities: recruiters may start pipelining for roles which are not yet on the market however they are on the look-out for talent should an opportunity arise the qualified candidate will be the first to know. This holds a greater advantage as recruiters may hold information which has not yet reached the market therefore less competition for the role.
  • Expertise and support: recruiters provide guidance starting from a candidate’s CV to preparation for an interview and after care. After care usually refers to regular check-ins with the candidate on how they are progressing in their search or if placed how they are finding their new journey. In addition to the above salary negotiation.
  • Networking opportunities: recruiters hold events which candidates as well as clients are invited to attend, this is a fantastic way to build a network with like minded people and potentially lead to a career change or full-time role if contracting on and off. For those who are in contrat & perm roles this experience is mainly for networking.
  • Wider pool: recruiters have access to a wider range of companies that are tailored and relevant to the applicant’s skill-set. A recruiter can usually identify if a candidate is suitable for a role after their first conversation.  This saves the candidate time as they don’t need to apply to roles he/she may not get a response from which is disheartening.
  • Reduced risk: agencies help navigate the candidate for the best choice for both the individual making a move and the client. Recruiters help candidates migrate the risk of poor choices whether it be the position or the company. 


In conclusion, to make this an exciting experience let us help you find your dream job!
