What A Server Cabinet Is Used For

All Network Administrator will be familiar with server cabinets, the purpose of a server cabinet is to ensure the servers are kept cool, stored in way that it is accessible for installations and maintenance, and help to reduce noise output.

Think of like a bunch of servers all stacked up onto each other, then enclosed in a state of the art server cabinet. These can be seen in many businesses, security offices and computer companies in a separate room or server cupboard. Server cabinets are typically available in a standard 600mm to 800mm width, and 900mm to 1000mm depth. They can also be available with a secure locking system, so the servers will be secure from theft and vandalism.

The cabinets can come in a variety of shapes and sizes, so you are able to fit the desired amount of servers in one cabinet. Co-Location server cabinets allow users to share between each other, further allowing good management of the cabling for maintenance and commissioning. The servers can be accessed through a doorway access from the front or the rear of the cabinet. These can also come open top, sliding side panel, mesh or glass front door and mountable profiles.

Most good quality and strong cabinets can be typically found in large data centres (purposely built for holding masses amount of data onto different servers), in which some cabinets are now able to cool the systems down without having a dire impact on the environment. Traditional cooling methods use a fan, which uses up a lot of energy. Newer methods involve a liquid cooling method as opposed to a fan. Using air conditioning tends to use up more energy in year than any other energy consumption devices.

Using a cabinet liquid cooling device is much more expensive than using air conditioning and fans, however, they are far more effective and beneficial than traditional methods for reducing carbon footprint emissions. Another way of being energy efficient in server rooms and data centres is through good cable management. Stray cables could easily restrict cooling vents and ducts. This reduces energy costs and ensures energy efficiency.

Even though they appear somewhat unessential to certain establishments, they are one of the most important features for many server rooms and centres. They help to keep every server in its place and prevent a disorganised maintenance facility.

Optimizing Your Computer’s Memory Potential

Think about the Internet as a highway and your computer is constantly traveling it. Add to that the trips your computer makes when working with applications that are not internet based, and you can rack up some considerable mileage that can result in computer problems if you don’t tune it up a bit every now and again.

In the dawn of the computer age, the proverbial geek took care of the necessary operations to help maintain a computer. Of course back then, by default, only geeks had computers. They were not household items in those days and only those who understood them better than they understood other humans had them. These geeks tweaked and optimized those early computers in an almost secretive manner-only because there was little contact outside of geek and computer relationship.

However, times have changed. Computers are in almost every home, in schools, and in the workplace. There isn’t a large enough geek population to assign a personal one for each computer to come and optimize yours when it needs a tune up. The need for keeping up with maintenance hasn’t evaporated though, and ignoring your computer’s need for optimization can result in noticeably slower running times or a computer that may refuse to work at all.

Since your computer didn’t come with its own personal geek, let’s learn a little about optimizing your electronic friend. First, start with creating a restore point. There is always the chance that something can go wrong and you could accidentally lose more data than you intend to if you don’t have a backup point. Many computers have this application included just in case you forget to do it. Some computers even create restore points periodically so that you have a way to undo whatever mistake you made even if you had no clue that your action would create a problem.

Create a backup of any documents you don’t want to lose on the same precautionary basis as the restore point serves. It never hurts to have a couple of ways to ensure that you can undo what you did if you need it. You can do this by simply burning the documents onto a storage disk such as a CD or a DVD.

Now, run a defragmentation on your computer. This can take a while if you haven’t done one regularly. It should be an option in the optimization options on your computer. Once it is done, take a click over to your antivirus software. Many of these have tools to help you optimize your computer. I know my antivirus program automatically tunes up my computer once per week. It keeps my system running as well as it did right out of the box.

Finally, delete any documents or programs that you don’t need. Just as keeping trash in your apartment takes up space, so do these documents on your computer’s memory. Don’t forget to empty your recycle bin after you’ve finished as nothing is deleted fully and no memory is freed up until that is done. This just opens up more room for your computer to do its thing.

6 Steps to the Perfect Computer Room

As more and more businesses rely on computers for the day to day success of their business, businesses are packing more computers in to offices, so that each member of staff has a PC and is truly efficient.

This is excellent, as the businesses are investing in the Technology, but eventually these businesses will discover they computers begin to run slow, then stop! The reason being, most organizations, do not invest in the actual computer room, this is the room dedicated to accommodating the servers and where the network infrastructure is terminated. It’s just the same as having a Formula 1 car and putting standard unleaded fuel in it, it will run but the performance will be no were near what it should be.

An independent survey illustrated this, by poling 50 top UK manufacturers, only 16 had a dedicated Computer Room, that had the relevant security in place to protect their investment, 3 used what you would call a cupboard to house the main server. One in particular stored the server in a room 3 feet x 4 feet, with the monitor balanced on the server while the keyboard was on the floor and this was a leading Global manufacturer worth over $5 billion!

To build the ideal Computer Room, you will need:

1. An access control solution. This can be a simple keypad entry system set a 4 digit access code and press the digits to gain access, or a more complete swipe card system, that logs each entry in to the room and sends an email to the Network administrator when someone tries to gain access when they don’t have the necessary privileges.

2. A false floor or suspended ceiling, either one of these are necessary for both structured cabling that runs the army of computers in the offices and air conditioning for cooling of the servers, to ensure the servers don’t crash.

3. KVM switches, these are the devices that can be used to monitor banks of servers from a single monitor and keyboard. KVM stands for Keyboard, video and mouse. The switches can be daisy chained together so that they can control and manage up to 345 servers per monitor, keyboard and mouse. These switches have a fantastic ROI, as they save money on the monitor, keyboards and mice that the business would purchase, as well as the extra expense of increased air conditioning to reduce the heat from the monitors and most importantly save a huge amount of space.

4. Storage of the servers. There are 2 types of storage, rack mount cabinets for rack mount servers and open LAN racking units that store free standing servers, monitors and keyboards etc. These units can be arranged, so they store 20 free standing servers with 1 monitor, KVM switch and keyboard controlling them, they are modular and more flexible for the ever expanding computer room and most importantly the most cost effective solution.

5. Air conditioning: If you have ever been in a computer room when 40 servers have been running for 2 hours, you will know how much cooling they require and this is paramount!

6. Structured cabling: These are the cables that connect each computer and if you were to trace each cable, they would run back to the computer room and to the server. These are normally classified as Category 5e or Category 6 data cabling and there are many Global manufactures of data cabling solutions.

Undelete Files With Confidence

It happens all of the time because nobody is perfect. It’s so easy for anyone to get distracted and accidentally delete an important file. I know plenty of people who’ve done this, including me. Here is the most important thing to remember: Undeleting files has a very high probability of success, but it depends on whether some other data has overwritten the file you need to recover. Running undelete or getting a recovery expert is the only ways to find out. You may be wondering why you just can’t you just look inside the recycle bin on your desktop and use the search function in the start menu? You can try this technique first to see if it does the trick. If you have already tried this and were unsuccessful, there are two more options: An undelete utility and file recovery services. Both have their advantages and disadvantages, but software is where you want to begin. How to get back your data In order to recover deleted files on your computer, the following conditions must be in place: The lost file must still exist in the directory. The sectors that were used by the deleted file must not be overwritten yet. The file must not have been fragmented. Directory: If you want to recover your files, the deleted file should still be available in the directory. In other words the undelete process requires that the lost data you are recovering not bee overwritten by new or different data created in the same directory. Sector: In addition to the directory, it is important that sectors themselves, where the original, lost file was located, not be overwritten with a new file. Fragmented files: If you really want to succeed with the undelete process, the file you are recovering should not have been fragmented since it was deleted. The sectors of the disk which once held your data must maintain it’s sequential order, undisturbed and not fragmented. You can recover your lost files Files that were accidentally deleted can usually be recovered without problems, but you need to move quickly before another file is saved in its place. If this happens, there is nothing you can do to correct it. Don’t wait a minute longer – take action now and begin downloading and using undelete software, or contact a disk expert. These two methods are the only way to know for sure if your lost data can be recovered. Ken Roberts recovers the simplest situations like undelete to the most severe problems like a dead hard drive. He believes the real underlying problem in data loss however is people don’t know what to do because most of them have never experience data loss. This data recovery article will inform the uniformed to help them make the best educated decision to recover their data.

Editor’s review of Actual Keylogger – Who says you can’t run a spy operation on the cheap? Actual Keylogger lets you record every keystroke typed on a computer, and it doesn’t cost a cent. It can’t snap screenshots or automatically e-mail reports, but it’s decently equipped and surprisingly convenient for a freeware program. It’s reasonably stealthy, too. You can conceal its folder, disable its record in the Add/Remove Programs dialog, hide its shortcuts, encrypt its logs and password-protect its settings. Unfortunately, the program process itself is unprotected, and a savvy user could easily spot it and stop it.

Data Recovery Hard Drive Success

Seeking data recovery hard drive assistance means you’ve tried everything you know to get back your files. At this point, you have a couple of possibilities, hard drive recovery software tools or hard drive data recovery services. And because there is rarely a second chances if something goes wrong, it’s important to follow a few tips when pursuing data recovery hard drive.

A few helpful data recovery hard drive tips

One of the most important rules of data recovery hard drive is to avoid using the computer with the lost data you want back. It may not make sense to you right away, but the reason for this rule is if you continue using the computer once you detect a problem, your chances of retrieving your files decreases. The file system of your computer will randomly execute a data destroy command to overwrite your missing files. If you are planning to use data recovery hard drive tools to get back lost data but are still working on the computer with a faulty drive, you need to stop what you are doing, remember or write this URL on a sheet of paper, and then bring it up on another properly functioning computer.

The second most common recovery hard drive mistake people make is to download restore data software onto the failing drive. This can also cause your data to disappear for good when your computer sends out the command to do so.

Last but not least, another common mistake people make when they are unable to locate their missing file is reboot the computer. This is actually the most common data recovery hard drive error made. As with the previous mistakes, rebooting your system can cause data to become lost for good when restarting the computer.

Why is recovery possible?

When data goes missing on your computer, it is not actually lost, it’s just hiding. The trouble is the index that points to the file’s actual location on the primary hard drive is lost. This is why data recovery is possible when acted upon quickly.

Make your choice

You have two choices to recover data. The fastest and most cost-effective method of recovery is using a software program that you run yourself. There are a variety of products available on the market, so choosing the right one can be a challenge. However, when your drive is failing it’s time to call on the professionals for help.

You may think you need to be able to match the disk data recovery program with the specific situation that caused you to lose your data. But that isn’t true. Even if you have no clue about what happened, you can start with an undelete program and work your way up one level at a time until you find the program that works. If this sounds troublesome, just choose the most powerful data recovery software available the first time around.

Seeking professional assistance

It’s possible that a data recovery hard drive program may not be enough to locate your data. If this happens, your only other option is to seek the services of a data recovery hard drive expert. Data recovery experts are a more expensive choice for hard drive recovery services, but this is the last alternative for hard drive data recovery. While data recovery service may be more compared to using recovery utilities, getting help from a data recovery hard drive specialist will reduce your risk of data loss.

How Much Memory Is Sufficient?

With the way technology is headed, how do you know what size memory is needed for your computer? For example, if you use your computer quite often then chances are that you will need a memory upgrade. One way to determine this would be if your computer is running slower than it used to, or two programs cannot run at the same time without trouble. It is possible that your memory has come close to full capacity. The more programs that you install and run, along with the files and photos that are stored on your computer, the less memory is available for use. This causes a lot of frustration due to computer crashing, slower performance and difficulty installing new programs.

Before buying more memory for your computer, you might consider making some changes. You can put files on a disc and free up that room by deleting the files that are now stored on a disc. Now that space is available for programs or new files that you need. Another option is to go to the start menu on your desktop and click control panel, and click uninstall programs. You can view which programs that you do not use and remove them, this will also free up some memory. You may have a lot of temporary files that are interfering with computer performance and delete these. This will also free up space that you need.

If you don’t want to delete unused programs or burn files to a disc, there are other options such as review how much memory is available for your computer. Another way is find out if all memory slots are in use already, if not then you could buy more memory and install into the slots for memory. For example if your computer has the slots for 2GB of memory but you only have 1GB installed then you can upgrade to gain 50% more memory on your computer. When you are ready to purchase memory it is best to go to a certified computer supply center and ask for the memory upgrade for your specific computer make and model.

If you have basic knowledge of how a computer works then chances are that you can install memory upgrade yourself. Let’s say for example that you want to buy memory to expand to 3 or 4GB, you may want to call a specialist to install or if you just don’t feel comfortable trying to install yourself, it may be best to have a specialist install the memory upgrade.

Another tip would be if you started to do the task yourself, but found that the installation is more involved than you anticipated, it is a good practice to call a specialist. It is better to be safe than sorry, such as you continue to try to install and find that now the computer will not turn on, chances are something was not installed correctly, or possibly you disconnected something that shouldn’t have been disconnected. If in doubt, call a specialist.
