Second Hand It Hardware

A computer is a combination of software and hardware parts, both of which are very much important to the proper running of the system. New computer hardware parts such hard-disks and RAM remain high in price because they continue to improve in capacity and speed, and if one holds onto computer equipment for a long time, then it can become obsolete. There is however a way to buy the same equipment in cheap prices, by purchasing it second-hand.
There are three main methods of purchasing used products:

-Buying directly from dealers and sale brokers: When purchasing used IT Hardware equipment from dealers and brokers, people should use common sense and should follow some basic rules. People should read the license agreement before purchasing the equipment and see whether there is a return/warranty policy. Test everything before purchasing the hardware equipment. Hardware parts such as system RAM, keyboard, mouse and monitor should be rigorously checked before purchasing the product.

-Online dealers: There are many online shopping sites available to buy second hand IT Hardware equipment. Sites like E-Bay, Amazon, OLX, etc are some of the sites where sellers advertise their used products online. If a person wants to sell his used PCs hardware parts separately, such as the hard-disk or RAM, he can do so by registering a new account with any of the above sites. He can then upload his products details and the price he is looking for. The buyers can check the product details and can communicate with the seller through online chat or messaging systems for any clarification, and if the buyer wants to buy the selected product he pays through online payment and will receive the product in the post. Online auctions have become a very popular way for sellers to sell their second hand equipment and earn money at the same time.

-Buying directly from the manufacturer: Manufacturing companies such as Sony and Dell sometimes have a second hand market where they used and refurbished IT hardware products. Mainly these are computer parts which have had some kind of problem and have had to be returned to the manufacturer under the manufacturer warranty. The problem may have been relatively superficial; such as the box being damaged, or a light scratch on the back of a monitor. The manufacturer is not legally allowed to sell the equipment as new, so they must find other ways to offload this problem equipment, sometimes at bargain prices.

To handle such situations, Exchange Server includes a repair utility called Eseutil. It can detect errors, repair them and defragment the hard drive. But this utility can not handle the situation in case of severe damage and you encounter data loss situations. At this point, you are required to go for Exchange Server Recovery solutions. Sometimes when you attempt to repair a damaged Exchange Server database using Eseutil tool, the process might fail and you may find the following entries in the Application Event Log of Exchange Server:

Best Forex Robot – This One Has Made Millions In Real Time Trading!

If you are looking at Forex robots, you will notice that most either simulated there track records backwards in hindsight or you have to take the word of the vendor there true with no outside chjeck so wouldn’t it be nice to find a robot that had a verified track record from neutral outside sources? Of course it would and the Turtle robot has just that a verified track record that the rules made hundreds of millions of Dollars…

The Turtle robot gets its name from the famous turtle experiment, where legendary trader Richard Dennis taught a group a novices a set of rules and then gave them trading accounts to see how they got on trading the rules. The rest is history, as they made $400 million dollars in just 4 years. Dennis set out to prove that anyone could learn to trade if they had the right system and he was proved correct.

The rules make money but until now, they have not been available in robot form but now they are and you can use these rules to seek big currency trading profits. On a risk of just 2% per trade, you can target 100% annual gains and you can take more or less, risk depending on your risk tolerance.

Cooling a Server Room the Cost-Efficient Way

As the servers are used constantly, they generate tremendous heat. When this heat increases beyond control, it may lead to damage of the devices and equipment. Being machines, the computers are delicate under the hood and are prone to damage due to carelessness. System crashes, reboots, hang-ups, untimely failures; poor performance and other problems can be created due to abnormal temperatures. Now, one way to keep these issues under control is to maintain the server room’s temperature. Sufficient ventilation, cooling and maintained temperature are the efficient ways to protect computers and servers.

Maintaining the temperature

The computers used at homes and for small offices come with internal cooling devices, which usually keep the desktops and laptops cool. Nevertheless, the server rooms that manage a number of systems do not have sufficient internal cooling systems. They have to be kept cool using an external cooling source, such as portable air-conditioner. Secondly, increased humidity inside the enclosed area can cause corrosion or rust. The maximum humidity level of a server room should not exceed 40 to 50 percent.

Are portable air conditioners good solutions for cooling?

The temperature of the server room should be steadily cool around-the-clock. If the room or storage area is connected to the central cooling systems, they may be shut down during the weekends or sometime late at night, depending upon the company’s working hours. If the cooling systems fail, the computer systems are prone to face the brunt.

Portable air-conditioners keep the server rooms cool, as the temperature can be controlled individually depending upon the outside temperature. There are few air-conditioners that adjust the temperature according to the outside temperature on certain modes. They are self-contained units which do not require permanent installation. Business owners can move these units anywhere as required.

A portable AC used in such places must have condensation tank to manage the humidity level, automatic restart function and proper ventilation to replace the hot air inside the room. These features not only keep the servers cool but also regulate fresh air and keep the machines working continuously. The automatic function keeps the air conditioners working continuously even when there is a power cut or failure.

When it comes to the size of the air conditioners it is never an issue. The server closet of size 9000 to 12000BTU will be sufficient for the unit to fit in. While a 12K BTU unit requires 9 to 12 amps a huge unit of 14000BTU requires 20 amps. The air-conditioner should be thoroughly checked for the necessary requirements before installation.

Multimedia Courses – Delhi

The spectrum of multimedia is getting dynamic over the years. Multimedia has emerged as a very effective medium of communication and the popularity of multimedia is growing by leaps and bounds. Multimedia is doing wonders as a marketing tool and in the process has also opened many job opportunities.

Small and medium enterprises have been able to reap maximum benefits from multimedia for their brand building needs. Multimedia confluences very easily with web based applications and a growing number of entities are applying multimedia techniques in their own websites as well as affiliate sites for marketing needs. The growing use of multimedia has opened several job openings in this sector. A cosmopolitan place like Delhi comprises business enterprises of every capacity, starting from MNCs to one man run organizations and since they all need multimedia, therefore the job opportunities in a place like Delhi is also immense. This has resulted in an increase in the demand for multimedia courses in Delhi. Delhi being the capital acts like a magnet for people from all over Northern India.

A comprehensive multimedia course would involve training on graphics, it would teach the use of software like Adobe Photoshop, Coral Draw and Illustrator. Students are then taught on story boarding, which is important for synchronizing the message that has to be communicated through multimedia. Story boarding is followed by lessons on animation that infuses life into still images. Animation brings motion to the whole process; there are two popular animation techniques namely 2D and 3D. Multimedia students are also taught about sound, linear and non linear editing.

There are several forms of multimedia, when we are talking about multimedia at a larger level it would encompass graphically animated movies, games and laser shows. Multimedia advertisements are a big hit these days in electronic and digital media. There are instances when even corporate movies are made in the multimedia format. Games have always been very popular and they are also a part of the growing family of multimedia. They are clubbed as non-linear multimedia because progress of the media is controlled by the viewer. Laser shows have emerged as a highly entertaining medium for wholesome family entertainment, the recent laser show that was displayed during the opening ceremony of the IPL 2010 stands as an example to this. A laser show infused with sound and music is also clubbed under multimedia.

Thus it can be convincingly concluded that multimedia is the future and it opens several avenues for success.

Precautionary Action Plan Of Hardware Failure In High Availability Database Servers

Hardware failures pertain to failures experienced by different component such as disks, controllers, CPUs, memory, routers, gateways, cables, tape drives, fans, and so on. Such failures generally call for the malfunctioning component to be repaired or replaced. Once thats done, regular operations can be restarted. It is important to maintain multiple components for those susceptible to frequent failures. Single points of failures are common causes of high downtime. For instance, twin-tailed disks that connected across two nodes or mirrored disks allow systems to remain functional even when a node or mirror goes down in the case of a node going down, there may be a brief disruption, again depending on the fail-over solution implemented.

If just a single component is maintained, during the time it is being repaired or replaced in the repair window, service will be unavailable. Sometimes, the time required to obtain a component can be horrendously long. For example, when we blew a disk controller at a client site, the hardware engineers determined that the component needed to be totally replaced. It was not available locally and had to be flown in from out of state, taking at least two days to get in and be replaced. Situations like these can cause tremendous downtime.

There is a chance of failure of hard disk or disk controllers too. Important thing is that, we cant able to judge this kind of hardware failure. But for precautionary action plan, we need backup server in high availability database server environment. If backup server is not possible in every cases then we need to make strong Service Level Agreement SLA with strict condition and response time with hardware vendors. Sometime we need to put some penalty clause too in response time measurement of replacement and availability of failure component. Using this trick we are able to maintain lowest downtime for high availability database servers.

A two-day service interruption may cause a company to out of business in certain cases. To avoid situations like these, some of my clients have a component availability guarantee clause put in all hardware contracts, wherein the vendor would ensure that specific components prone to failure would be available locally or obtained within an acceptable predetermined time period from specific remote sources for immediate replacement. Identify all critical components are augment them with clones.

Additionally, all hardware should be maintained securely inside cabinets to prevent accidental or intentional damage. All guidelines from the manufacturer temperature, proximity to other devices, and so on should be strictly followed. Cabling should be done as neatly as possible, so as not to get in the way of people walking about. Raised floors in your data centers greatly help in preventing accidents.
