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.


Emerging Trends In Computer Peripherals And Networking Hardware.

Owning a computer, is in no sense these days counted as an item of luxury.

Regional of category of entry is the keyboard, mouse, touch screen, joystick, scanner, microphone or camera, therefore any device designed to receive information after the installation of the software covered by this type of material computer. Appliances specifically designed to give results, according to information given as input fall into the category of hardware output devices such as printers, speakers, monitor, headphones are all that give a result as both speakers and headphones emit a audio, monitor and printer display information either as a softcopy or printed form.

Material does not change as software or are newly constructed anything material, in contrast to the language of software that will keep the issue of climate wise. Hardware is only small additions to previously existing equipment, which does not change the overall operation of the equipment. Hardware notes will save a huge amount of money and time to go around in search of a technical expert for fixing hardware issues. With little effort networking computers can also learn to have greater market demand. With the full understanding of the material and notes some basic networking can land a person for jobs as technical support offered by many software and manufacturing companies. There are also telecommunications companies, BPOs have positions for customer support and resolve technical issues associated with their computer?

Computer hardware and networking are together in such a way as to allow data processing and communication within a network which can be either the internet or intranet. The architecture of hardware and network can consist of routers, computers, access points, hubs, network cards, modems, adapters, firewall and other optional materials, if any. Most hardware and network device used is Ethernet adapters these days are an integral part of the personal computer.

Hardware Virtualization Support In Modern Cpus

To avoid the issues surrounding the non-trappable privileged instructions, CPU manufacturers have added virtualization capabilities to modern CPUs. These CPUs still need to behave exactly like their older counterparts, to ensure backward-compatibility with existing applications, so the behavior of the non-trappable privileged instructions is identical on these newer units. However, a new set of instructions, which were not previously available, provides for a special virtual machine mode of operation. This mode provides extra levels of I/O and memory protection, and allows the special instructions to be detected and handled externally by the CPU in conjunction with a suitably written hyper visor VMM.

The first revision of this instruction set provided basic support for virtualizing the non-trappable privileged instructions, and the supporting instructions required to interface the hardware support to VMMs written to make use of it.

CPUs with first generation hardware virtualization support are not capable of nesting VMMs in a way that allows the nested VMM to also take advantage of the hardware virtualization capabilities. This means that when using CPUs with first generation hardware virtualization, only the outermost VMM can benefit from the hardware acceleration. While this may not initially seem to be a problem, some modes of operation are not possible without hardware virtualization support, meaning those modes will not be available in a nested-VMM configuration.

Furthermore, some computer manufacturers intentionally disable hardware virtualization support in their PCs, even if the hardware is capable of supporting it.6 The second revision of this hardware support, present in only the newest CPUs at the time of this writing, does allow virtualization of the hardware virtualization instructions, allowing for some degree of nested VMM capabilities.

Limitations and Challenges

Performance There will always be some level of performance overhead associated with hyper visor VMMs. As CPUs evolve to include more hardware support for virtualization, the areas of performance impact will shift from the VMM to the emulated hardware instead, which can still result in a non-trivial impact.

VM inside another VM As mentioned before, unless one uses extremely new hardware it is not possible to run a hardware-accelerated VM inside another hardware-accelerated VM.

No hardware assist Especially important in a virtual desktop solution, one must consider the millions of PCs in the field that could be used as host PCs that do not have even the first generation of virtualization support.7

Optimising Your Server Rack for Networking Hardware

Server racks have more than one use, including saving floor space by mounting several hardware on to it or if it’s to protect it from various hazards and natural disasters such as earthquakes, overheating, liquids. Other uses involve reducing sound via soundproof enclosures or make the working environment look more tidy and professional as a lot of server racks have space for cable management.

A server rack is very important when it comes to networking hardware, as it ensures that the servers are running smoothly by keeping the temperature cool and thus prevent overheating which in turn reduced the down time of a server and keeps it running smoothly. There are many accessories and types of specific enclosures that can be used in order to keep the temperature at a certain amount.

Another important factor to consider when getting a server rack is to make sure that it has extra space for all the cables. This is especially important in busy environments with lots of people, as lots of cables on the floor could cause people to trip over and cause injuries and damage to the hardware itself, which in networking hardware would be even worse, since valuable date could be lost. Being able to manage your cables within the rack prevents any cables from lying around which is a lot more appealing within a working environment.

Not only do server racks make your working environment a lot safer and more professional, but they also simplify the use of your hardware. Without having a lot of tangled wires to sort through all the time, or being able to easily mount your hardware without worrying about space or overheating, as the airflow design of a server rack forces the hot air out, ensuring the temperature is kept cool at all times.

And another really important factor to consider are the various accessories that you can use for your server rack, in order to suit the hardware that is inside it. Such as wall mount racks, which can save you floor space or if you need the hardware to be mounted at a certain point on the wall. There are also extra fans if your hardware generates a considerably high amount of heat. Finally there are a lot of accessories to prevent damage to the valuable data in case of an earthquakes, accidents or fire, which is especially vital for networking hardware.
