How Platespin Server Consolidation Works

It is no secret that servers can take up a lot of floor space, and power. As a result, they can sometimes seem inconvenient. One way to save space and power is to consolidate servers. Server consolidation is very important in order to ease some of the frustrations of overdue consolidation processes. Server consolidation projects can also be accelerated via automation and virtualization. Platespin server consolidation helps to accelerate consolidation projects, and reduce errors. This is done without actually having to have contact with the physical machines.


Platespin allows managers to measure and evaluate resource utilization in order to speed up capacity planning for consolidation projects. This is accomplished by remotely gathering information about the server. This information can be the server operating system, memory, CPU speed, the network, and memory. Platespin server consolidation works on Windows NT, 2000, and 2003 systems. The system works without the help of agents. Therefore, the need to manually deploy software is eliminated. The risk of missing certain agent dependencies is also eliminated in this case. Platespin is also very simple and lightweight, so it can start to collect data in almost one minute.


Platespin completely automates the physical to virtual migration of data. This allows the servers to be consolidated quickly and with more ease. There is a drag and drop interface that allows the user to convert machines running Windows or Linux into one fully functional virtual machine that is hosted on several types of servers. These servers include VMware GSX Server, Microsoft Virtual Server 2005, or simply a Platespin Flexible Image file.


Network configurations, CPU cycles disk space, and memory allocations can all be converted rather quickly.  This ease allows users to right-size target servers as the conversion process is occurring. As a direct result, data centers are made able to increase the number of servers that are able to be consolidated. This further optimizes resource utilization rates.


Sever consolidation may seem complicated, but the right program can make it quite simple. Platespin automates many processes and allows many different factors to be converted quickly. This means that the total time for consolidating servers is reduced.

History of Hewlett Packard and Ink

Hewlett Packard’s tryst with ink took off when it acquired a company named F.L Mosley based in California in 1958. Mosley was manufacturing recorders and plotters for industrial applications such as continuous process monitoring systems, data loggers and the like in the 1950’s. 

Hewlett Packard was the pioneer in imaging and printing technologies. It was the first in the market during the 1980’s to come up with inkjet and laser technology used in printers until date. Its first printer was the “ThinkJet” in 1984 based on the inkjet technology and later the “DeskJet” printer also based on inkjet technology and the “Laser” printer as the name suggests based on laser technology.


The Ink

Today inks are not just gooey fluids filled in cartridges to give you images on your print media.  Specially engineered ink gives high quality prints-it has specially designed active agents and colorants that give rich color and fade resistance.

There is a difference between printer ink and toner - printer ink is a liquid that is applied to paper by pressure. Toner is a fine powder that is burned onto the paper through heat and laser guidance.

There are two types if ink - dye based and pigment based. The rest are a variation of these two basic types.

The Ink Cartridge

The printer cartridge nowadays is not only an object that holds ink but also a highly technical one that has an integrated circuit to control the quality of printouts. The printer ink cartridge is by far the most important consumable as far as its cost, type and replacement is concerned. Every printer model has its own specific ink cartridge.

Inkjet

The inkjet cartridge is a combination of speed and precision. Each ink nozzle in the cartridge fires up to 36,000 drops of ink per second to deliver crisp text and sharp images.
The Inkjet and DeskJet printers use this cartridge. They are ideal for home and personal use.

LaserJet

The Laser Jet cartridge comprises up to 70% of the total imaging system and therefore plays a key role in delivering quality prints. It uses a precision laser to draw the image giving clear sharp and precise prints. These are ideal for home as well as small to large businesses and workgroups.


Design Jet

These cartridges give uniform fills, sharply defined lines and crisp clear text across a wide range of durable printing applications. These cartridges are used for large format printing media such as trade show and event displays, posters and presentations, photo enlargements, architecture and engineering applications such as CAD/CAM.

Color Layering Technology

In color layering, a number of microscopic droplets of colors ranging from three to eight colors are combined and managed through hundreds of small nozzles in the cartridge. The result is a print of high quality with vibrant and realistic true to life images. This technology gives a wide range of colors up to millions.


Available Cartridge Options

1. OEMs
OEM (Original Equipment Manufacturer) cartridges are the same ones that come with your printer. The company that makes the printer generally manufactures them. For example, HP laser printers come with HP toner cartridges. OEM laser printer toner cartridges are the most expensive type. You can save money by choosing remanufactured cartridges, compatible cartridges or refill kits.

Benefits of OEM Cartridges
Many manufacturers recommend only using OEM cartridges with their printers to achieve the best results. However, they are also trying to get you to buy their product. Again, if you require optimum quality then it is best to use OEM cartridges. They also prove to be economical in the long run because remanufactured or refilled cartridges may fail 70 to 80 percent of the time in their first attempt or they usually don’t give as many prints as the original or as promised by the remanufacturing company. 

2. Remanufactured

A remanufactured cartridge is one that has been disassembled and its worn parts replaced. A new print head is then fitted onto the cartridge, is refilled with ink, and is tested in the factory to guarantee print quality. Remanufacturing is considered more comprehensive than refilling. 
         
Your printer's print head cleaning utility (described in your printer's operating manual) should always be run 1-2 times after inserting a remanufactured cartridge. They are thoroughly tested to ensure quality, and their performance is generally equal to new cartridges. 

Just because a cartridge ran out of ink, does not mean the print head and electronics are not still in perfectly working order.

3. Refilled

Refilling your cartridge means cleaning the cartridge and refilling it with new ink. Now, either this can be done at home using a refilling kit or you can ship your cartridge to a refilling company in your area.
Some refilling companies claim that Refilled Cartridges are environmentally friendly and provide a high quality output, which meets or exceeds consumer expectations and that they are
· Ultrasonically bathed to ensure a clean print head
· Filled with top quality inks using state of the art equipment
· Tested to ensure high quality printing
· Sealed and packaged in vapor resistant material

 It is best to refill your Cartridge within 15 days of the cartridge becoming empty.
Empty cartridges have a certain life span and this can range from between one refill to five refills on average. However, cartridge circuits have been known to fail on the 1st attempt of refilling / remanufacture and in contrast, cartridge circuits have been known to last up to 10 refills, the latter being exceptional durability.
Once a cartridge circuit has failed, the ink cartridge is unusable and a new or serviceable cartridge has to be purchased.

High Definition Tuners

High definition TV tuners or HDTV tuners are designed to receive high definition programs by connecting to an external antenna. HDTV tuners will not only show movies and DVD’s at high definition, but will improve the viewing of normal TV. It is because of the improved definition or color and picture quality of DVD’s and programs that make HDTV tuners very popular with viewers.

Television sets often come with HDTV tuners already built into them, these are called integrated HDTV’s. If you are considering buying an external high definition TV tuner for your television, make sure that your TV set is HDTV compatible. A separate tuner may also be needed. This can be either a cable or satellite box for watching high definition programs.

Most people have heard that there is a mandate on televisions to make integrated HDTVs. This is not entirely correct. Certain televisions that are for sale after a certain date will be required to have built in tuners. The tuners required won’t be HDTV. The mandate is actually referring to ATSC tuners. It is not even necessary that TV’s be able to display HDTV resolutions without either an internal or external tuner. This new mandate will not apply to plasma and front projectors. The mandate will not take effect for some time. Until then there will be no change in television manufacture or tuners.

It is important to ask about features of high definition TV tuners before making a choice. If you are not sure what some of the features are, ask for clarification. Make sure that your television is compatible, HDTV tuners may not work with older televisions. Ask your cable or satellite company weather they support high definition TV, as many people find out later down the road that they cannot receive HDTV programs through cable or satellite.

Ask about what kind of warranties are available and what parts they actually cover before buying. External high definition TV tuners are quite reasonably priced. Prices start at around $150. If you are on a budget, make sure not to buy cheaply made appliances. Always wait for specials or price reductions on reliable brands.

One of the most popular brands available is the Samsung SIR-T451. This one is ideal for high definition programming on any high definition TV compatible television. There are many more HDTV tuners available on the market. By doing a quick search on your favorite search engine, you will be able to find a HDTV tuner that will fit both your budget and your TV’s requirements.

Here's How To Get Sound From Your Speakers

This article was written to answer many of the most frequently asked questions on this topic. I hope you find this information helpful.

You have tried and tried to get your speakes to work. You have the sound card and the speakers; so what is the problem? The first step is to check the connections. Most people accidentally plug the speaker jack into the Line-in Jack of the sound card. Check to see if this is what you did. If you have amplified speakers, make sure that the power is on and mute is not.

Check and see if the speakers work properly before trying to troubleshoot your system. Do this by connecting the speakers to a music system or radio. If they do, the problem is definitely related to the system.

Check the volume levels in the system. Check the volume controller in the system tray and also open the advanced audio controls to make sure that there isn't anything muted or at really low levels. Now use several multimedia applications to play various media files to insure that the problem is truly system related, and not limited to a particular application or file. If you find that only a certain application has the problem, such as Windows Media Player or Winamp, reinstall it.

If all this is to no avail, go to the system properties [Windows] + [Pause/Break] or right-click on My Computer and select Properties and in device manager make sure that sound card is installed properly. If you see a yellow exclamation mark, reinstall the drivers.

If you have an integrated sound card that is disabled in the BIOS, then Windows will not be able to detect it. Refer to your motherboard manual, and find out how to enable it. Usually it is present under the advanced peripherals section in BIOS.

If you have access to another PC, plug the sound card into that system, and check if it is working. If the problem persists, take the speakers to a technician.

Help to choose your monitor

Making the right choice in a computer display or monitor is an important part of involving yourself in today's web-browsing and multi-media technology. Right now, you are viewing this in a computer monitor (unless you've had someone print it for you and you're reading it on paper because your monitor made it completely unreadable) and how it appears to you depends entirely on the quality of your display.

Monitors

What are the differences between an LCD screen and CRT monitors?

LCD screens are the current trendy looking; flat screen displays that are now sold with practically all bundles, whereas CRT screens are bulky older style technology. Apart from the space saving that the flat screen LCD (Liquid Crystal Display) offers, it also generates very little heat and radiation, uses considerably less power and is less reflective. LCD screens present excellent image quality. CRT (Cathode Ray Tube) monitors on the other hand, occupy a lot more space on your desktop, do generate heat and use more power and usually have a curved screen (although flat screen CRT monitors are available).

From a display point of view, the major difference between the two lies in how the image is created, and the resolution that the screen can accommodate. Each pixel in a LCD screen is produced by a tiny cell containing a layer of liquid crystals that bend light in response to electric energy. While they can be clearer than CRT screens, they are limited by only one optimal resolution. Setting the screen at a higher than optimal resolution reduces the overall screen image, and at a lower one causes the screen image to appear "pixelated".

A CRT screen creates its image through cathode ray emissions striking the phosphorous lining on the back of the tube glass. It offers more detail in images and colour at higher resolutions.

One other difference to note is the display size. Display size is the diagonal measurement across the screen. A 17 inch (these have not been metricated yet) display is measured from one corner diagonally to its opposite. In a LCD display, this covers the entire framed display, but in a CRT monitor, the display image is usually 8%-10% smaller than the framed screen area, which means a 17" CRT monitor has to have a bigger framed screen than a LCD.

Compatibility

There are possibly two issues of compatibility to consider. One is the compatibility of the screen with your workspace and the work you want it to do. If you have a small space, then the slim features of the LCD will be a major part of your decision. It is better to buy an all-digital screen rather than one that plugs into a standard video card (which is analogue) and then translate an analogue signal to digital. An all-digital display will offer brighter images. Compatibility with your computer's video card is another consideration. You need to be sure that the video card you have in your computer will provide the screen resolution your require from your monitor and match the refresh rate.

Technical considerations

Dot Pitch. This is the distance between the same colour dots in any direction on a display. A smaller dot pitch enables easier reading of characters and better colour clarity. The maximum dot pitch you should consider for high quality graphics and text is .28 for a 17" monitor and .31 for a 21" monitor.

Screen resolution. The number of pixels a screen displays determines the resolution. A resolution of 1024 x 768 has 1024 pixels in the horizontal plane, and 768 in the vertical. The higher the resolution, the more detail is displayed. Be sure that your video card matches the resolution you require.

Refresh rate. This is the frequency at which the screen image is being refreshed to avoid flicker. A vertical refresh rate of 75 HZ (cycles per second) delivers a flicker-free environment and will reduce eyestrain and fatigue.

Cost

Of course it all comes down to what you can afford. But a good quality display is a good investment in your work environment. CRT monitors can be bought very cheaply. Digital LCDs can become very expensive. Manufacturers are now offering displays with inbuilt television receivers and speaker systems than can enhance your overall environment and improve the flexibility of your purchase. Ultimately, it depends on what you want to see on your desk as much as what youn want to see on your monitor. You can spend as little as $200.00 or well over $2,000 and you can do it all online.

Hardware: Now What Exactly Are We Talking About?

Now just because this article is on the internet doesn’t mean that the hardware that we’re talking about has anything to do with computers! I mean that is probably the case but why don’t we remain patient and civilized and find out before we start jumping the gun and squawking about hard drives and monitors and video cards and CPUs and the like. Lets take a minute to consider what else we could be talking about and make sure it isn’t those things before we proceed any further down the computer path.

Hardware could be ACE or The Home Depot right? I mean after all most retail stores today are trying to maximize their market share and are therefore making available many services including a large part of their inventory online. So maybe you are looking for a new compound miter saw or some 35 year guaranteed shingles. Maybe you want to replace that old squeaky screen door. Maybe you have a leak in your plumbing that needs immediate attention. Well you are going to have to stay tuned because I may be able to help you.

Within the above category of hardware there is another category of hardware that refers to the handles on drawers and doors. This is a surprisingly popular market sector as shows like trading spaces, extreme makeover, and Martha Stewart’s Home show. People, especially with the economy being rather slow, have decided that instead of getting new things that they will just make due with their old cupboards, or doors, or desks, or dressers, etc. But they are willing to spruce them up by refinishing them and adding new, more generationally acceptable, knobs that match the simple yet elegant and refined look of today. Silver not gold; brushed or “antique” finish rather than a chrome shine.

Ok, ok so I am talking about computer hardware I just wanted to let you know that this may not be what everyone else is referring to when they are talking about hardware in an article on the internet. Any this is a great time for those struggling with their computer components. Online support is getting more and more useful and soon you won’t have to ever take your computer anywhere to have it fixed. A technician will be able to analyzed, diagnose, and correct problems over the internet and you will be on your way without much bother at all. Sounds good doesn’t it?

Hard Disk Clicking Sound

1. Observations
You hear clicking sounds emitting from your hard disk drive, either in a form of clicking or grinding sounds. This can happen when you power up your computer from start or halfway while working on your projects.

2. Possible Causes

The irregular clicking or chunking sound usually indicates that your hard drive is suffering from physical damage. If you use a S.M.A.R.T enabled disk, you may see a warning of a imminent disk failure when you power up your computer. This problem can be caused by the following:
- Head Crash
- Bad Sectors
- Mechanical Faults
- Virtual Memory Paging

3. Resolution
a. Head Crash

This is a physical damage of the disk platter when the head of a hard disk scratches the surface of the disk. The grinding sound is therefore observed when this occurs. Firstly, turn off your computer and do not attempt to power it up. Consult a data recovery firm immediately and avoid dismantling the disk to repair the problem yourself. Operating without the correct tools and a clean environment can result in further extensive damage which complicates the recovery process.

b. Bad Sectors

Typically bad sectors are physical damage of a span of disk area. The clicking sound happens when the head attempts to read from the same area of disk multiple times due to failed attempts. This can also occur when the head is unable to calibrate with the media servo tracks due to the gradual weakening of the magnetic domains on the platter that causes the drive to reset continuously. If the conditions of the disk is not too bad, a standard process is to perform a disk surface scan. This helps to mark all bad sectors and prevent your system from writing new data on the damaged areas of the disk.

c. Mechanical Faults

Sometimes these sounds can be a result of a defective spindle, Read Write head or loose components. If you are still able to access data on the disk, you are strongly advised to backup all your data immediately. Your disk is close to demise. If your disk stops spinning after a period of clicking sound, you may wish to send your disk to a reputable data recovery firm to recover your data.

d. Virtual Memory Paging

When your physical memory is full, the drive may perform numerous virtual memory paging at the same time maintaining the system's operation. This will result in excessive disk activity. To deal with this problem you can increase the physical memory by adding more RAM into your computer or use a secondary hard disk to contain the swap files.

Further Notes

Hard disk drive occasionally produces a whirring sound when it searches for a file which is heavily fragmented. This is caused by the spinning platters as the read-write heads zoom back and forth to access the sectors where the data is stored. It is important to distinguish the whirling sound from the clicking sound. This whirring sound can be reduced by periodically defragmenting your hard drive. Defragmenting reorganizes the scattered data on the hard drive to make files and programs run faster. It relocates the commonly accessed files to the beginning of the hard disk where data can load at a faster rate.
