Optimization of Energy in Data Center

Opt for virtualization is just one of the actions that can be taken to ensure the sustainability of the environment.

Recent study at Stanford University points out that from 2005 to 2013 there was a 48% increase in energy consumption in data centers in the United States. Fewer than many analysts predicted, but still significant. In an economy in constant instability, it is worth taking a look at how to increase energy efficiency in data centers, especially because in many cases the energy efficiency can be obtained without major repairs of IT equipment or facilities.

1. Determine use

The first step in making the data center more energy efficient is to find out exactly how much electricity the environment uses, and where, specifically, electricity is consumed. My first recommendation is to perform an assessment of the data center to quantify the energy use means for the company. The Green Grid has a metric to use energy called PUE that involves dividing the total energy used in an installation by the IT equipment. You do not need to be sophisticated to quantify the consumption of primary energy. Understanding the PUE can provide a perspective on how you can be more efficient.

2 Check the account

Another very simple way to record improved Energy efficiency is always evaluate carefully the account of the data center, a practice not much performed by IT departments today. It is recommended to examine utility bills in an effort to find areas that could be more energy efficient in the question. While monthly costs do not always correspond to inefficiencies, they can at least highlight where opportunities for improvement are.

3 Prepare for virtualization

Once initial assessments are carried out, examining where to cut electricity usage. Specific strategies will vary from data center to data center. However, server virtualization is a common strategy that can reduce energy consumption and costs significantly by replacing many physical servers. To extract maximum virtualization, or any activity that aims at efficiency, the company has to consider the ripple effect on data center operations. If your server storage is about 80% usage, you must ensure it is monitoring the power requirements to make proper use. By implementing virtualization, the density of workload increases on certain servers, with this, power and cooling should be adjusted according to the racks of servers. A review of the cooling architecture can lead to significant savings with minimal effort. With this action, you can register for energy efficiency around 20% to 40% savings. This action can be as simple as move the air-conditioning to near virtualized servers, a strategy called close-coupled cooling. The idea behind the close-coupled cooling is to have more control over the supply of cold air and warm air capture. You can employ the right cooling required for a particular rack at the time that it takes.

4. Fill voids

When virtualized servers are removed from a rack, you can create problems with the cooling and energy efficiency. Fill the empty spaces within racks, cabling, panels etc is vital in this scenario.

5. Adapt approach

Virtualization facilitates the creation of zones. So you can have a highly used area within the data center, which will allow literally close all other areas of the environment. In turn, the appropriate power and cooling capabilities can be located precisely where they are needed. Zones organized according to applications can also allow better load balancing data center, server efficiency and redundancy requirements. For example, back office applications can be setup in an area while mission-critical systems in another. Instead of delivering the same amount of redundant power and cooling throughout the mission critical zone can be targeted to the highest levels of redundancy and cooling. The opportunity to save energy in the data center requires looking at more variables. Efficiency load and redundancy work together to optimize energy consumption.

6. Save with air coming out

Besides taking care of the internal air, which comes from outside should also be taken into consideration. Data centers are often maintained by increasing the temperature according to the needs of the equipment. Meanwhile, data centers can save to rely on outside air for cooling. Increasing the internal temperature of five degrees will not compromise the performance of the equipment IT, and will allow the data center to enjoy the days of cold outside to keep the proper temperature.’s economy generated using this method can be seen quickly. It is possible to record energy savings of 50% or more every hour that the company use the economy mode. Optimize energy use across the data center can be a time consuming exercise, but following these relatively simple steps you can register major economies.

Sysadmin BORN

There is a problem. A problem in my industry is that, it is growing every day. It’s called “improvisation”. We define the person “improvised” who, after installing a server following a howto and copy paste commands without understanding them, feels, on a par with much more skilled systems engineers, ready to manage production systems. And you throw at it.

The (real) professionals are having to fight every day to attacks of various kinds, from spam to DDoS, and in 99.9% of cases it turns out that they come from the machines, in fact, in the hands of people who have virtually no experience in the management of systems.

I have not told here for mercy for those concerned, but some time ago some sites on a server that I manage, all belonging to the same person, were affected. After a thorough analysis of the logs, I concluded that those who had entered via FTP password (probably recovered with a keylogger). Having found in the logs of the IP deface, I contacted the owners of two of those, definitely become part of a botnet and used by third parties to infringe. The first, after an initial response particularly rude, confirming that he had not noticed that his server was being used by third parties to deface websites, has taken the necessary measures. The second, no. He threatened me, saying that I would have sued for defamation, because what I was saying was surely invented, and that if the provider, in which abuse had reported the matter, had locked the server, I would have asked for damages. Because I was making it all up.

Needless to say, after having explained how to connect via SSH and how to launch the ‘last’ command, they come up login (root) from all over the world. Login to whom he obviously knew nothing.

He was not sure what SSH was, but the server was installed. The services were up, the website was functioning properly. Why this? Why are we in 2014. Why are control panels and howto. Control panels such as Plesk and cPanel, which play very well for all the initial setup and ongoing management of a machine. That’s the point. Systems Engineer improvised, it does not matter that you cannot already do with a simple click in the control panel. It does not matter that you cannot do on the internet and looking for a guide copy paste the following commands.

In fact I consider howto’s on par with the control panels “handyman”. Step by step guides that lead even the most unable to configure a specific service. Systems engineers improvised exist because there are step by step guides, and these guides exist because they sell, because they make views, and because they are improvised. The fact of the matter is that the guide explains how to install and how to do basic configurations. But it does not explain how to handle. It does not explain how to deal with exceptional cases. Why is this, perhaps, cannot be taught.

Those who use a ready guide, delegate to a third party (ie the one who has written the guide) throughout the preliminary phase of research, documentation and assembly of different sources, as well as testing. Instead, it is a critical component of our work. Why is it that we learn to move without the use of guides, this is the way we learn to deal with situations that are not ordinary. It is thus, and only thus, we learn to walk (or rather, running) in the dark.

We assume that everything can be explained in simple terms and sequentially clueless, can also be performed by a machine. Years and years of howto on how to install a LAMP environment. Then comes cPanel. He invents EasyApache. And from that moment with a command you can do all that in 3 seconds with the guide was done in 3 hours. A copy lines of code are all capable. The machines are very respectable to run commands in sequence. They are the best: we invented invented us, and we have invented to do just that.

This suggests that a person who manages machines in this way, it makes no sense to exist. If the administration of a system consisted only in these simple and sequential operations, the machines themselves would know self-sufficient. Indeed, they do already: there are structures which carry 90% of the routine tasks without human supervision.

But managing server is much, much more. The last little ordinary situations, and you’re often having to manage case studies exceptional in having to perform operations that can not be run through a control panel. A need to perform operations for which you do not find a ready guide anywhere, because maybe before us no one has found stuck in the situation in which we find ourselves instead. Interventions that serves the human mind, a brain. A brain that works, not just a brain that knows how to use the cut and paste commands.

Yes, it is true, many tasks have been automated in recent years, the first place a man and now a car. But beware: the automation processes that already Systems Engineer held in “automatic”, behaving like a machine. Only those, everything else will never be automated. Maybe you one day happen. But not in the short / medium term.

Some argue that it is precisely in this innate ability of sysadmin. Knowing how to deal with situations, how to handle exceptional case studies, how to manage (and fix) problems. Knowing how to look for solutions, knowledge and ability to use the tools available. Having the trend that brings you every day, without any push to find new tools and to discover new things. The technical skills you can acquire, the rest not: you will learn the commands to use, but you do not learn the way we deal with critical situations. And that’s what counts, this is to make a difference.

Often, when an improvised council to change profession, I do not know why he has proven to simple commands or did not know the meaning of some technical terms, but because the well-known lack of skill and trends much more important. Sometimes I get covered in questions, questions whose answer is contained in the preview of the first search result on Google. This, in my opinion, is a clear sign. If your instinct leads you to ask someone who already knows how to look for them yourself rather than an answer, you’ll be a perfect student, a perfect slave of modern educational methods. But, still, you will never make the system administrator. That’s it.

Some people are born especially brought to the team game and physically agile, and becomes footballer. There are girls who are born very fine, fine and brought to the attention of the person, and become models. It is not clear why it is rather widespread belief that anyone can become a systems analyst. It is not clear why anyone who wants to become one, and why it is so difficult to defend the professionalism in a trade that is becoming more critical and important.

You never want to fly on a plane piloted by a person holding a step by step guide. There you would never transplant the heart from someone who, strengthened by 20 years of experience in the butcher’s shop and with the help of a video on Youtube, you warrant that you know how to do. Why, to save a few Euros, take in hand your sites, your management and your communication tools for people who do not do anything more than they already do not make the machines themselves?

For now I’m done.

Disaster Recovery Solutions for Business Continuity

A profitable business is one that thrives underneath each circumstance and smart business continuity plans are very important for the organizations, as these can keep the business in an exceedingly running mode through the interruptions. Of the common challenges Janus-faced by the business homes ar power failures, IT system crashes, software system defective, natural disasters, provide chain issues, political problems, transportation and supplying problems.

In a technology driven business world, once equally of data is offered simply accessible across geographical boundaries, it becomes all the a lot of necessary for each organizations to possess a disaster recovery and business continuity method as an area of the structure methods. analysis has shown that ninetieth of the business that face disruption finds it troublesome to search out for a correct disaster recovery strategies and techniques.

What then is Disaster Recovery? it’s a coordinated activity to modify the recovery of IT and business systems once any disruption. this will be achieved by restoring the IT or business operations at any various location, convalescent the operations mistreatment alternate instrumentality, or acting operations through various strategies, which can embrace manual strategies too.

Disasters aren’t any a lot of incidents that occur once within the product lifecycle. something from knowledge corruption, viral infection of the info enclosure, security breaches, software system bugs, hardware failures ar all reasons which can cause a system or Associate in Nursing structure unit to prevent functioning. thence most firms each tiny and medium enterprises and huge business homes choose to place a correct disaster recovery strategy in situ aboard the opposite structure methods.

Business continuity designing on the opposite hand could be a a lot of comprehensive approach to make sure the flow in business return what might. With the continuity of business and its result on the force as its core areas of concern, these 2 strategies are incorporate united underneath constant strategic umbrella. thence whether or not it’s Associate in Nursing IT organization, a provide chain management company, a producing unit or simply Associate in Nursing body concern, the Business continuity and disaster recovery plans revolve round the security problems and clarity in communication.

Organizations that offer this business continuity disaster recovery got to reply to disasters in an exceedingly systematic and non-chaotic manner. The solutions provides ought to be ready to retrieve and shield the structure knowledge against potential threats, minimize disruption and operational losses, manage recovery operation in effectively, restore and build back confidence of investors, stakeholders and customers, managing the complete image and name moreover as survive through the disaster.

Difference between Semi-Dedicated and Dedicated Server Hosting

Dedicated server hosting has been an all time favorite for business owners looking for independent server space and performance. It has been a winning choice for corporate enterprises with huge server requirements. Dedicated Server Hosting is being provided by many web hosting service providers.

If you business requirement are continuously growing but have not reached up to a scale wherein you can make a switch to a dedicated server then you could cater to your growing requirement by going for a Semi-Dedicated Server. Semi-Dedicated server hosting will provide you with all the same features and functions as of a Dedicated Server, the only difference being that there will be 5 to 6 users in total for that Semi-Dedicated Server. Semi-Dedicated Server hosting has seen great increase in demand in the recent years because of its suitability for growing businesses. It has become an ideal choice for users looking forward to have independent server space but at an affordable price.

Both these server are completely managed by the web hosting service provider, also providing support. Having independent server space would ensure that you don’t face any downtime because of other server users. Its very important for business owners to avoid any kind of downtime because it has a direct affect on the daily business of the website or company. Thus the only difference between Semi-Dedicated server and Dedicated Server Hosting is the number of users. There can be upto 5-6 users for a Semi-Dedicated Server wherein a Dedicated server would be only yours.

Dedicated Server Colocation

Colocating your dedicated server can be a good option for housing your expensive hardware at some reliable datacenter which will reduce overall server hosting cost. Many big organization have considered server colocation as an affordable & reliable option for hosting your server.

It presents an cheaper, attractive alternative to building and maintaining a sizable very expensive data center.

There are many benefits for keeping your hardware & network equipments off-site at some secure & reliable location.

Following are benefits of colocating your hardware at datacenter…

- Most important is the cost factor, it eliminate the up-front costs for setting up and building your own data center.
- You can deploy your required IT infrastructure based on your current network at much lower budget.
- Relocation :- If you are planning to relocate your company physically without affecting your network status then such colocated servers/hardware will help you avoid any sort of network downtime or other interruptions.

Well, though there are few benefits of colocating serves/hardware we should not avoid it’s disadvantages.

Dedicated server colocation is not favorable if

- The overall space and load requirements for your company network is high.
- Your server hardware requires intensive management.
- If physical security is a major concern for your company.

Server colocation service providers will charge you depending on total physical space required, amount of bandwidth, amount of UPS protection, quantity and type of power distribution, and the degree of physical security needed, server management etc… hence you think as if server colocation is not a one-size-fits-all solution for data centers. it’s like choosing between buying your own house versus renting an apartment, your decision to maintain your own data center or hire a colocation provider should be weighed based on your current & future network requirements.

Usually colocation is preffered for short term benefits for smaller organisation, but the option of colocating/housing servers and network equipment off-site should be evaluated after doing your research & homework.
