Server Virtualization Challenges

Server virtualization is a business strategy that is here to stay and that offers many considerable organizational benefits. You can consolidate application workloads that are running on underutilized servers which can result in reductions in hardware costs, energy and infrastructure costs, and space requirements. Additionally, server virtualization can also increase the availability and reliability of applications, improve disaster recovery efforts, and streamline data backup.

Realizing these server virtualization benefits does require some effort. These fantastic benefits are not automatic, despite all the hype surrounding server virtualization. They require a skillset that may be new to some organizations, and thus planning needs to be taken seriously and with forethought. Server virtualization, in fact, may not be a good fit for your organization and so when possible, a consultant that has experience in virtual server deployment and a strong virtualization methodology should be used.

Server virtualization works best for applications that utilize less than half of a servers capacity or resources. Larger, transactional database applications are typically not a good fit for server virtualization.

Given the fact that most servers are grossly underutilized, there is a huge waste of IT resources likely at any organization. Virtualization uses a hypervisor, which is software that transparently allocates server resources and manages resource conflict. This, in turn, allows multiple applications to share the same physical server increasing the utilization of the machine. While simple in theory, there are challenges that come with server virtualization.

Workload capacity and performance planning

When you suddenly increase the utilization of an underutilized server, you automatically create the need to better manage that servers performance. Depending on the application being run on the server, this increased utilization could cause problems.

Operational processes and procedures

Like the first challenge, the sudden increase in server utilization may require your organization to redefine internal processes for monitoring performance, and possibly the tools used to monitor server diagnostics.

System architecture and design

Youll need to determine (before your server virtualization effort) how virtualization will affect overall budget, system component selection, how much CPU, storage capacity, and network bandwidth youll need so that your effort runs smoothly.

Storage allocation and management

Youll need to consider application transaction rates and capacity usage so that you allocate the appropriate amount of storage space. If not, youll run the risk of exceeding available capacity and constraining your application performance.

Security

Security vulnerabilities are amplified in a virtual server environment, so be sure to address security patching and access control.

While these challenges are not tiny, they are very manageable provided theyre addressed prior to server virtualization. Consult with a server virtualization expert to help you get it right.

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.

Dedicated web server

Dedicated server hosting it suggests that it is all about taking a hosting server on lease. Not like shared hosting where you share the bandwidth, data storage with other users. In dedicated server hosting you have complete control over its hardware, functionality and other stuff. You can control your own server. This is the elite webhosting type. This is best suited for the website with huge traffic. Generally dedicated hosting is the costly web hosting service due to the customizable option you get with the hosting. The price of dedicated server varies with the alteration of operating system you use, the amount of RAM you want in your dedicated server, the type of processor you want in the dedicated server, and most importantly the amount of bandwidth and storage capacity you opt with. Apart from this the number of IP address can also increase the aggregate cost of the lease of dedicated server. HostGator.com is well known entity in the world of web hosting.

Drupal And Object Oriented Programming.

As all the OOP languages use CLASS or similar data structures for Object Oriented Programming, we have considered that without a “CLASS”, OOP is not possible.

Object oriented programming (OOP) is quickly taking place over the traditional procedure oriented programming (POP). Programming languages like C# and Java are successful because of OOPs Power.

After gone through the code of “Drupal” – One of the most popular open sources content management system and framework built with PHP language, summary is – Drupal doesnt use a single Class in its code base. Whole Drupal code base is based on just functions. As PHP, with which programming language Drupal itself is built, is also implementing many powerful OPP features, but Drupal is not using these features.

Actually, the OOP concept is not based on uses of data structures like CLASS. It is based on the fundamentals of features like Objects, Abstraction, Encapsulation, Polymorphism, Inheritance etc. If these fundamental features are included in programming then it can be considered in OOP.
There is no keyword ‘class’ in Drupal code. Drupal is as non-OOP as many programmers do. But that is not true. Drupal doesnt contain any class like data structure; still it is still Object Oriented.

Drupal covers all these features without classes. Power of Drupal is hardly depends on this programming structure only. The way, how the hook system has been implemented in Drupal would never been possible with the use of Classes.

Keep Those Back Injuries At Bay With The Sl500 Server Lift

Around, 80% of the injuries in the workplace are back injuries due to heavy lifting. This can be more common in a data centre, as the majority of rack mount equipment, like servers are extremely heavy items of equipment. In order to reduce the likelihood that injuries would occur, the use of a server lift can be incorporated into your work environment.

Like any piece of equipment on the market, there are a lot of choices, so choosing the correct piece of equipment is vital to the smooth running of your company. Many of the data centres where we work tend to be rather cramped and the areas between the server racks can be quite narrow. The SL500 server lift has a great advantage over its competitors as the footprint of the machine is really small. The SL500 server lift width is just 24 inches, so manoeuvring through slim isles is made a lot easier with this equipment.

An important factor when choosing a new server lift is to make sure it meets the current OSHA (Occupational Safety and Health Administration) guidelines that are set out. The SL500 server lift meets and in some cases, exceeds those guidelines. This can not only assist you in making sure that your workplace is as safe as possible but if used properly, it is highly unlikely that any accidents are going to occur.

As far as the weight that the SL500 server lifter is able to handle, the maximum is 500 pounds. So what about the height it can lift to, the SL500 server lift can lift equipment to a height of 8 feet, making it very convenient to lift equipment to the higher levels in your racks. In addition, you can also lift other items such as heavy batteries and with the included strap handles, remove items safely from a box with the use of this server lift.

The controls that operate the SL500 server lift are not only easy to understand and use, but extremely easy to manoeuvre heavy equipment very precisely in to and out of your racks. The brake/stabilizer locking system helps to keep the server lift in place while you are positioning the equipment.. The onboard controls supply you with the ability to manoeuvre any item into very small places, so that the server or any other hardware can be slid into the rack conveniently.

Selecting the right server lift can not only help you to make sure that your working environment is safe, when you choose the SL500, you’re also giving yourself an efficient piece of equipment that your entire workforce will appreciate.

The SL500 is definitely a piece of equipment to think about as it ticks the right boxes and gets the job done.

Using an XML Content Server for Profitable Publishing Instead of Investing in Publishing Software

Publishing enterprises today are looking to new platform applications instead of purchasing publishing software to help their content produce profits in this electronic age. The publishing industry has changed its market from traditional paper media to the electronic age of publications. Instead of publishers giving away their content online by means of the World Wide Web, publishing companies are reining in their valuable information and using XML platforms on top of their existing contentbases to create new products, reuse existing content and take advantage of XML management all without the need to purchase publishing software. >

In this electronic age, where so much content is virtually free and accessible, with online advertising as the form of income, publishing houses have been competing to still make a profit from their enormous content bases aside from online ads alone. Now, with XML as basically a standard, at least for the W3C, publishing houses are choosing to go with an XML platform, like an XML content server to fully maximize their content and help with content management. All forms of content can be easily converted into XML with an XML content server, including paper files, graphics and charts and graphs. The XML content server provides an XML platform allowing organizations to unlock the value of existing content where it previously wasnt profitable before.

Other large contentbase organizations have benefit from this XML platform: Government, insurance and any other private or public organization that do not wish to complimentary publicize online- though needs an enterprise search to filter all of their content can use an XML content server for exactly the same purpose. With an enterprise search, your organization is able to only search within its secure database and retrieve more than just pages showing listings of files that may have what you are looking for, these XML servers retrieve whole articles, texts, images and even video all within one query into the enterprise search engine.

Because XML a common standard for most of the web, blogs, online books and articles and not to mention Office Open XML, where OOXML automatically creates content into XML, with an XML content server and OOXML its no wonder that enterprises are turning to XML platforms to aid their content into new and profitable ways.

About the author:Melissa Peterman is a web content specialist for Innuity. For more information about publishing software or XML Platform go to Mark Logic .

Windows Small Business Server 2008 Standard and Premium Editions Exceeding Expectations

Another new function is the Read-Only Domain Controller (RODC) that allows IT staff to configure the Active Directory infrastructure as read-only. Such a configuration keeps Active Directory replication unidirectional, rather than bidirectional, as it is normally configured. An organization could use this setup once again in the branch office location where connections back to the central office may not be as fast or as reliable. In this situation, Active Directory would be configured at the central office and then sent out to remote sites before it is accessed. Combining configurations of Server Core, BitLocker and RODC provides a level of security in the Server 2008 release impossible in prior releases. Configuring machines as read-only guarantees the data cannot be compromised even if a hacker were able to penetrate perimeter defenses. Also, if a theft were to occur in which a server was stolen at a remote site, BitLocker guarantees the data contained on the machine to be indecipherable, while RODC controls allow for administrators to reconfigure the network with a few clicks of the mouse.

Internet Information Services (IIS) is the server-side technology that first became available with Windows NT 3.51 back in 1995. With the seventh full release of IIS available for the first time in Server 2008, the service becomes fully configurable. Web administrators specify precisely which services they would like to enable – and which services they would like to disable. All of IIS 7 is also supported by the new Server Manager console.

Versions and Licensing

Several different product editions of Windows Server 2008 are available. Depending upon the version, each type is configured for specific hardware platforms, such as 32 bit or 64 bit, and versions are available with virtualization capability built in, while others leave the function out.

It is important to understand Microsoft’s different available methods of licensing when purchasing server products. The Microsoft Open License is intended for smaller customers with less than 250 desktop computers in their network. As few as five licenses can be purchased and with these licenses, the owner has the right to transfer images to different machines or transfer a license to another machine.

Microsoft Volume Licensing is intended for networks serving more than 250 computers. Within this group are several account levels that offer flexible payment scheduling. The same rights are established as with the Open License, but there are added discounts for the volume purchases.

Both types of licensing come with the option to add Microsoft’s Software Assurance plan, which provides maintenance for Microsoft products.

Software Assurance includes comprehensive support including training and the ability to speak with Microsoft representatives to assist in deploying and managing Server 2008 software. Software Assurance should not be overlooked in any Microsoft purchase. With the purchase, software upgrades are included in addition to Version Rights, which guarantees the purchaser the right, at no extra charge, to new editions of the product purchased should one become available during the length of the Software Assurance contract.
