What is Veritas Volume Manager

          VeritasTM Volume Manager (VxVM) is a storage management subsystem that allows you to manage physical disks and logical unit numbers (LUNs) as logical devices called volumes. A VxVM volume appears to applications and the operating system as a physical device on which file systems, databases and other managed data objects can be configured.

VxVM provides easy-to-use online disk storage management for computing environments and Storage Area Network (SAN) environments. By supporting the Redundant Array of Independent Disks (RAID) model, VxVM can be configured to protect against disk and hardware failure, and to increase I/O throughput. Additionally, VxVM provides features that enhance fault tolerance and fast recovery from disk failure or storage array failure.

VxVM overcomes restrictions imposed by hardware disk devices and by LUNs by providing a logical volume management layer. This allows volumes to span multiple disks and LUNs. VxVM provides the tools to improve performance and ensure data availability and integrity. You can also use VxVM to dynamically configure storage while the system is active.

VxVM and the operating system

VxVM operates as a subsystem between your operating system and your data management systems, such as file systems and database management systems. VxVM is tightly coupled with the operating system. Before a disk or LUN can be brought under VxVM control, the disk must be accessible through the operating system device interface. VxVM is layered on top of the operating system interface services, and is dependent upon how the operating system accesses physical disks.

VxVM is dependent upon the operating system for the following functionality:

    operating system (disk) devices
    device handles
    VxVM Dynamic Multi-Pathing (DMP) metadevice

What are the advantages of Title Tags, Meta Tags and Meta Keywords

Meta Tags :
           The meta tags are a very important part of the HTML code of your web page. They are read by the search engines but are not displayed as a part of your web page design. Usually they include a concise summary of the web page content and you should include your relevant keywords in them. Most meta tags are included within the ‘header’ code of a website. The most important tags are the title, description, keyword s and robot tags. It’s important to note that there’s a big difference between Title tags, Meta description tags and Meta keywords tags. First of all, the Title tag is *not* a Meta tag.
Title Tags :
    The meta title is the most important tag on the page. You can see what your competitors are using as their title tag by looking at the blue bar at the top of your browser when you visit their website. You should always work your major phrases into the Title tags on your pages, and make sure that each page of your site uses a unique tag. The title tags should be between 10-60 characters. This is not a law, but a relative guideline a few more symbols is not a problem. You won’t get penalized for having longer title tags, but the search engine will simply ignore the longer part.
Meta Description tag :
    The Meta Description tag gives a brief overview of the document. The Meta Description tag is a short, plain language description of the document. The description tag should be less than 200 characters. Search engines that support the Meta Description tag will use the information to publish on their search results page, normally displaying below the Title of your site listing. The meta description tag also has a great importance for the SEO optimization of your page. It is most important for the prospect visitor when looking at the search engine result page – this tag is often displayed there and helps you to distinguish your site from the others in the list.
Meta Keywords tag :
      The meta keyword tag has become the least important tag for the search engines and especially Google. However, it is an easy way to reinforce once again your most important keywords. We recommend its usage as we believe that it may help the SEO process, especially if you follow the rules mentioned below. It is recommended to use the Meta Keywords tag with caution. Make sure to only use keywords that are relevant to your site. Search engines are known to penalize or blacklist your site for abuse. The Meta Keywords tag also exposes your keywords to your competitors. Search engines used to look at this tag too, which contained a list of keywords the webmaster wanted to rank for. Unfortunately people started abusing it and nowadays you get no additional boost for using it in your pages.

Most common mistakes webmasters make with their websites

        Even the most skilled and advanced webmasters make mistakes that lead to security problems. This is most often due to webmasters not giving much thought as to how even the simplest action could be valuable to a hacker, or the general denial that something bad could happen. There are many mistakes that new webmasters and old web masters make that cause them to get banned or blacklisted from search engines.
      Some search engines are changing their Algorithms every month due to a few bad SEO’s who are using techniques to try and trick the search engines so that either their clients or their own WebPages position higher in search engine ranking position (SERP).  We can say with almost a certainty that if you are using illegal or worst yet outdated methods for the purpose of achieving higher positioning you will be caught and banned.
Here are some of the most common mistakes webmasters and business owners make with their websites.

A website made by an amateur web designer will yield professional results.
Your business or organization website is not the place to publish an amateur representation of your company, organization or services. You are not just presenting your business image to your local community and surrounding areas, but to the entire world. Obtaining the professional services of an experienced and knowledgeable webmaster will save you thousands of dollars in the design and development of your website and business growth goals utilizing the World Wide Web.
Cluttered Home Page
You have probably seen these sites there is so much information on the page it makes it impossible to know where to start first. Simplify the process and have a clear plan on where you want your visitor to go. Simply put, make it easy for them. Start with eliminating as many icons and buttons as possible. Keep it simple for your visitors and they will not only stick around, but they just might come back, which is a very good thing.
If you build a website, people will find you
One of the biggest mistakes today is business owners fail to recognize the high importance of Internet Marketing programs such as an ongoing Search Engine Optimization (SEO) website marketing campaign. Your website needs to be designed and developed by a professional webmaster and needs to include a real internet marketing plan in mind from the get go.
Submitting multiple Pages with different titles
Submitting multiple versions of the exact same page or a similar page for indexing. This method is called Spam. Many web masters try to increase their page count by having similar pages and only changing the title, subject or small word changes.
Page swapping
This is where you submit a page that is positioned high and after it is indexed you upload a different page with the exact identical name and replace it. A huge mistake. SE’s don’t like it and anyone who visit’s your site from a page that has been swapped will most likely report you for spamming.
