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.

The Principle Of Retinal And Iris Scanning Technology

Fingerprint method can be misapplied. This reality is proven scientifically correct. For that reason, people then try to find the more reliable biometric systems.

The retina is part of the eyes that is responsible for the ability to see. The pattern of blood vessels that forms the retina is as unique as fingerprint. The principle of retinal scanning technology is scanning the pattern of capillary blood vessels on the retina with low-intensity light sources.

In 1987, the first retinal scanner was made by Leonard Flom and Aram Safir and has been patented. However, by the year 1994, John Daugman developed the technology of iris scanning as a competitor for retinal scanner.

Retinal scanning principle

Retinal scanning is based on the fine capillary network that meets the needs of oxygen and nutrients to the retina. These blood vessels absorb light and can easily be visualized with appropriate lighting. To that end, the close distance between the eyes and a scanner is needed. The appropriate position of eyes toward the scanner is also necessary. Also, there must be no eye movement, such as blink or glance.

Retinal scanning can not be 100 percent accurate. It is also less suitable as a security tool because even though the pattern of capillary blood vessels of human beings’ retinas cannot change generally, but diabetes, glaucoma, and cataracts can change it.

Iris scanning

In its development, retinal scanning is considered to be too disruptive in the case of security detection devices. In the use of retinal scanning, the eyes should be as close as possible with the scanner. For long-term, the light of scanner that is too close to the eye can give negative effects.

Because of the weakness, iris scanning technology emerges as strong competitor. Iris, a network that gives color to the eyes is also unique in which the chance for two identical slices is 1:1,078. Even, the left iris and right iris of someone are different.

Making Money with Articles – Picking a Good Web Hosting Company

Picking a good web hosting company is important to keeping your website open and your costs down. There are many to choose from, as well as different pricing plans to look over. Depending on the amount of sites that you intend on building, you may want to consider a larger web space in the long run.

You should start with the smallest web space that you can get to test the waters, just incase niche website Internet marketing does not work out for you. You may want to add on later, so make sure that your provider offers that option.

You will want to choose a provider that has a reliable service. If your site is down or takes to long to open up when visitors are trying to get in, it may lead them to click out of your site and move on to the next one. They will also more than likely not visit in the future since they will remember their bad experience. For this reason, it is probably best to stick with a well known company who you can check reliable references on. There are many small hosting providers that offer space for as low as $.50 to $1 per month, however, you never know what you will be getting and many of them want you to pay for at least a years worth in advance.

You will also want one that has the most affordable hosting. If you can create your own small site or have one made for you, then you will probably be able to find space for as low as $3 to $4 per month. However, if you need to choose a company that offers a What You See Is What You Get (WYSIWYG) website builder, then you will probably end up paying $10 to $15 per month for the smallest amount of space. But if this is the only way that you can build a site, then it is necessary.

Some web hosting providers may also offer a deal on a yearly URL or other products when you make a web hosting purchase.

Ultimately, whatever web hosting provider you choose will depend on your individual needs and what you can afford. Hopefully you will be able to snap up a well known provider at a low price who will allow you to upgrade your service as needed.
