Data Center Technician Job Description

Data Center Technician Job Description

Data center technicians are skilled, hands-on professionals who provide a variety of services to keep computer data servers and hardware networks operating smoothly. They are the first line of defense in safeguarding a company ‘s valuable information. Most data center technicians have full-time schedules but do not work a typical 9 to 5 shift. They work shifts that are 8-12 hours long on nights, weekends, and holidays. They normally work in server rooms where usual office noise, machine noise, or construction noise is present. Data technicians must be willing to respond to emergency calls 24 hours a day, since data support is vital to any business’s core operations.

 Data Center Technician Duties and Responsibilities

Specific job responsibilities of a data center technician differ according to where they work. However, there are several core tasks associated with the role. Based on our analysis of multiple job listings, these include:

Perform Preventative Maintenance

On a daily basis, data center technicians complete preventative maintenance of equipment and data network devices. They operate in tight spaces, run cables, and improve physical security around their assigned data center. Data center technicians engage in building projects and check utilities. To make sure the center does not overheat, they carefully examine power sources and heating and cooling controls.

Server Management and Repair

Data center technicians troubleshoot and repair servers that have hardware and network issues. They run hardware diagnostics and replace failing parts. They are responsible for day-to-day performance and capacity management of servers. If something goes wrong, data center technicians are called on to quickly fix it in order to keep business data flowing.

Monitor System Processes

Monitoring and maintaining operation of all network processes is the primary duty of data technicians. They evaluate machine temperature levels for optimal performance. Data technicians are expected to maintain accurate work records and event logs. They also create concise virtual information reports to keep company management informed of status updates.

Cross-Collaborate to Protect Data

Data technicians install and arrange new equipment for data centers. This may include physically upgrading internal system components (CPU), memory hard drives, fiber cables, copper, and more. Once they install new equipment, data technicians often collaborate with software and networking engineering teams to ensure cybersecurity and network efficiency.

Technical Support and Education

Data center technicians provide live support to clients and coworkers, and are expected to troubleshoot problems as they occur.

Active Contingent Definition

Let's say you've found your dream home online on the multiple listing service, but the status of the property is marked "active contingent." What does "contingent" mean, and is the real estate still up for grabs? Does "active" paired with "contingent" mean that the property can still be yours, if you make the right offer to a seller?

Read on for some explanation about this real estate listing status and for some insight into making an offer that will make the seller and buyer happy when a property is labeled contingent.

What does 'active contingent' mean?
If a home's status is "active contingent," it means that the buyer has submitted an offer to the seller with contingencies, or issues that must be resolved before the sale of the property can be finalized.
When a home is listed as "Active Contingent" or "Active with Contingencies," it means the seller has accepted an offer from a buyer and a Purchase and Sale Agreement exists, but that certain conditions (or contingencies) must be satisfied before the sale can be finalized. These conditions may include a home inspection or getting approved for a mortgage loan. Once these conditions are met, the home is no longer listed as Active Contingent. In certain areas, Active Contingent is also known as Active CAPA (can accept purchase agreement). What is the difference between contingent and pending?

Can I do freelance work while employed?

 freelance workers online

Yes, I have freelanced workers online while holding a full-time development job. It is possible, but everything needs to be right. Any time you do something like this, it is important to act with integrity ... both to your employer and the person you are working with. If you don't, it will likely all cave in on you. Here are a few things I think are important if you decide to do something like this:

1. You have to love what you do. If you don't love writing software, you will not be able to handle the fact that you are spending ALL of your time working. If you love what you do, then you aren't working, you are doing what you love.
2. You need to have a job where you have time do freelancing. In my case, my boss wanted me to put in 40 hours/wk and no more. I have been at organizations where they believe the own you 24x7. If you are already working 60 hrs/wk or more, you don't really have time to do any freelancing.
3. Your current employer needs to be aware of what you are doing. In my case, I asked my boss (who also happened to own the business) and he said, "Yes, I think everyone should own their own business". This kind of attitude is rare in the business world, but if you care about your employees, this is the right attitude to have. Sure, you could freelance without talking to your employer, but only do this if you don't care if you will be fired. In many companies, having a "second job" of any kind is grounds for termination. The world is smaller than you think.
4. You need to be doing something that is not in competition with or interfering with the market of your main job. The customers need to be different, the focus needs to be different and you need to make sure that you are not courting customers that are already customers or potential customers of your main job. This points back to the integrity point. This may be a bit vulgar, but dogs have a rule: "Don't poop at the same place where you eat." It's a good rule for your work life as well.

If the situation is right and you follow the advice above, you can do well freelancing and potentially turn it into a full-time business for yourself. If the situation isn't right and/or you don't follow these rules ... you will be putting both your full-time job and your freelancing career in jeopardy.

Noc Definition

 

Stands for "Network Operations Center." It is the central location where a company's servers and networking equipment are located. The NOC may reside either within a company's campus or at an external location. Smaller businesses and organizations often have an internal NOC, in which local technicians administer and monitor the servers. Larger companies may have a NOC setup at a location developed specifically to house server equipment.

Network operations centers, often called datacenters, are almost always connected to a high-speed Internet connection. Large NOCs, such as those used by Web hosting companies, are often connected directly to the Internet backbone. This gives the servers the most bandwidth possible.

While NOCs are used by all Web hosting companies and ISPs, they are also useful to companies whose services are not related to the Internet. Many companies use a NOC to manage internal communications, administer employee e-mail accounts, and backup data. Because maintaining an Internet connection is vital to most businesses today, most NOCs are monitored 24/7, with automatic alerts that notify technicians when servers or network connections are down.

How does Wireless LAN work?

 Radio waves are used in a wireless network just as they are used in televisions, mobile phones, and radios. Communication in a wireless network is very similar to two way radio communication. Basically, first a computers wireless adapter changes the data into radio signals and then transmits these signals through the use of an antenna. Then a wireless router receives the signal and decodes it. It then sends the information through a wired Ethernet connection to the internet. This procedure also works backwards in which the router receives information from the internet and sends it to the computer.

Advantages of a wireless networks

Wireless network is the recent development in the arena of network technologies. Wireless technologies have removed the obstacles to work on any remote area carrying personal digital assistant. The ease of connecting to the network has further helped in coming with the devices with third and fourth generation technologies. Wireless networks are cheap and easy to set up. You may access the internet from multiple computers, laptops, handheld computers, and even mobile phones that have wifi just by having a wireless router in your home or office. So now you don’t have to wait for your turn to use the internet because it can be used at the same time on multiple devices by a single a connection. The most obvious advantage of a wireless networks is that you don’t have to worry about getting tangled up in wires because there are close to no wires at all. Therefore, you can go from one place to another without having to worry about plugging and unplugging wires. Now many restaurants, most hotels, airports, apartments all have wifi access allowing internet users to be connected at all time. An advantage that most people seem to overlook of a wireless network is that since there are no wires the chance of tripping and injuring one self is minimal or close to none.

Establishing a wireless connection

We can say that establishing a wireless connection is a technical and expensive task. However this is not the case in reality. Establishing a wireless network does not involve many technical personnel and the machines. It is a simple network to establish as there are no wires involved. A person has to install software at large and he or she just has to buy a router. If we overall compare the cost of wireless network with that of wired network, wireless network is comparatively cheaper .wireless network is one time expense. Whereas a wired network need to be constantly updated and monitored. One more aspect involved in the network cost is the need for technical staff. This technical staff in some cases is the burden on the company, wireless network does not require any network assistant, and thus it eliminates the human resource cost at large. We can add more stations to wireless network as there is no hassle of wires. There is less destruction in case of electricity failure and natural disasters.

Ease of carrying wireless technology

Wired technologies were safe and stable but they are hard to carry due to their extensive wired network. Suppose you want to shift your working space or even home where you have established any wired network lets say LAN Ethernet. While shifting you have to remove the extensive network of wires from the building. Hence you are not able to carry it with you. When you will shift to a new space you need to establish a new connection. However, if you have any wireless router you just have to put it into bag and can be carried easily.

IT support specialist job Description

Information technology (IT) support specialists provide technical support to users of various software and hardware systems. As an IT support specialist, your duties may include installing and upgrading software and hardware, adding or moving computer equipment, and assisting with software rollouts or patches. Information technology specialists also triage technical issues through monitoring and responding to service logs, providing troubleshooting guidance, and resolving technical problems. Administrative tasks for an IT support specialist encompass verifying software licenses, maintaining equipment records and databases, and the procurement of technology. Information technology support specialist roles can be found in virtually any organization with an IT department. Although you can expect to work standard office hours, information technology support specialists may be on-call to resolve urgent or critical issues.

Managed Dedicated Server Hosting

Today, digital agencies are attempting to run their businesses much leaner. Designers and developers want the freedom to focus more on their core business. They want to create, not administer the infrastructure or manage the technology and data. That’s not what gives them passion and it’s not why they are in business. But hosting and infrastructure are what Liquid Web does best.

What is Managed Hosting?

Those in the digital space are familiar with Managed Hosting in one way or another.

This is a business model where a service provider leases hardware to a single customer. The service provider also provides management of the servers, software, and networks necessary for hosting for the customer.

If an issue arises, a managed hosting provider is there to help pinpoint the problem and rectify it.

Fully Managed Dedicated Server Hosting is an isolated hosting environment where the provider handles the setup, administration, management, and support of the server or platform application. The resources are specific to the user ensuring that your data alone is hosted in your environment without being affected by the issues that arise from sharing resources.

Shared Hosting

Shared hosting is the most popular example of multi-tenancy. This is where many sites or applications exist on the same server. Quite often, shared hosting divides the server resources among customers. This would include storage and bandwidth and in some cases RAM and CPU cores.

Think of shared hosting as a home with renters all sharing the same living space.

Managed Dedicated Server Hosting

Dedicated hosting would be an example of single-tenancy. With this type of environment, a single customer hosts their site(s) or application(s). With managed dedicated server environments, the server hardware and resources for that hardware belong to that single customer.

To continue with the above analogy, think of dedicated hosting as a home with one occupant. This avoids “noisy neighbors” encroaching on your space, disrupting your space and the space of those visiting your site.

13 Honest Data Center Technician Salaries

 

data center technician salary

Salary averages can be misleading. One culprit? Geography. A salary in San Francisco doesn’t compare dollar-for-dollar to a salary in Charlotte. Another culprit? Math. Quite simply, outliers (i.e., expensive cities) skew the data. That seems obvious, right?

It’s easier to report a national average without context, but it’s better to look at regions than national averages to determine honest salary averages. That’s why we took a look at the salaries of data center technicians, by city (like we did for Information Security Analysts and Ethical Hackers).

Utilizing Glassdoor, LinkedIn, and local postings, we looked at salaries in 13 cities to get an accurate sense of the data. More importantly, we focused on cities that house large data centers.

It’s well known that more than 70 percent of the world’s internet traffic passes through Loudoun County in Northern Virginia. But, every one of these cities wooed companies to bring their data centers (and jobs) to their region with the two things every data center needs — cheap power and lots of land.
