SAN(Storage Area Network) vs NAS (Network Attached Storage) vs DAS (Direct Attached Storage)

October 17th, 2012 Comments off

A NAS is cheaper storage than a SAN – Both can use RAID, if you had four 16 TB NAS boxes they would appear as 4 seperate pools of storage, conversely four 16 TB SAN’s would appear as one 64TB central pool of storage. Furthermore a SAN can be set-up to asynchronously replicate with another SAN over fiber perhaps in a different building, also a SAN can synchronously replicate with another SAN on a different site. Having an iSCSI interface on a SAN which therefore means the hypervisor is installed on the physical server yet it actual storage is on the SAN, meaning you can upgrade the entire physical server / blade without having to deal with moving large amounts of data about. Growth of the SAN is also easier, just by another SAN and add it to the pool. An example of how ESXi or Hyper-V can be used with a SAN (Two boxes), if you buy two servers with no hard drives at all, use a memory card installed inside the server to install the hypervisor (Install VMWare ESXi or Hyper-V) with one SAN (Two boxes that replicate with each other) per site, you can use the servers CPU and RAM to connect directly to the storage. The servers can then be separated into teir 1 and teir 2, etc allowing the virtual machines to use the CPU or RAM on a particular server. When VMware ESXi 4.1 Standard is used, you can use the vMotion to transfer servers whilst the users are using them.
DAS which stands for direct-attached storage is ideal for local data sharing requirements. It is the most basic type of storage and found very less when compared to SAN or NAS. In DAS storage devices are the part of host computer which are connected to a single servers with RAID arrays or tape libraries. Unlike SAN and NAS this enforces network workstations to access the server while connecting to the storage devices. Despite being oldest of the three DAS’s storage system still can be found among lot of IT infrastructures.

Shared web hosting and dedicated hosting can be seen as being at opposite ends of the spectrum in terms of the web hosting services that are available from a majority of web hosting companies. Whilst a shared web hosting plan is often put together with beginners in mind, most dedicated servers can be customized during the order process to offer something that is individual to the business or individual that is going to be using it. Shared web hosting plans often carry low resource assignments and a feature-set that will allow a beginner to make the most of their first domain name and get a website online, the benefit here being that shared web hosting plans also carry a comparably low price tag to suit the intended audience. Dedicated servers are tailored towards the other end of the market, providing a level of performance that can’t be matched by any other form of web hosting; as a dedicated server is a physical server, you will have the option to make modifications to the hardware during the order process – you can choose from a range of different hard drive configurations that use RAID or boost the memory and CPU power that you have on tap.

Question Mark Which form of hosting is going to offer the highest level of performance?

A shared web hosting plan is never going to be able to beat a dedicated server in terms of performance because dedicated servers are only used by the owner of that server, whereas a shared web hosting server will be used by many users. However, in terms of the performance that each intended audience requires, both forms of hosting will be able to serve their market’s performance expectations with no issues. Small websites don’t demand large resource allocations – especially when the website in question has only just started out – and it is because of this that a shared web hosting service will be more than capable of supporting small websites; a dedicated server can be expanded to host websites that receive thousands of visitors everyday, with a number of advanced configurations available such as load balanced clusters.

Will dedicated hosting or shared hosting offer the best features?

With shared hosting you can be guaranteed a full set of features as these will be set out as part of your web hosting plan prior to purchasing the service so that you know what you are going to be getting for your money. A web hosting provider should always offer a choice between Windows and Linux so that you can expect features common to the Windows platform such as MSSQL and ASP.NET support, whilst the Linux variant will be more suiting to developers using PHP and MySQL at the core of their web applications. Dedicated servers provide you with a dedicated environment that can be tailored to meet your needs as you wish, with a choice between Windows and a number of different Linux distributions (versions of Linux) being the standard offering; you can customize the hosting environment offered by your dedicated server to include any applications or services that you would like to use in conjunction with your website to produce a highly functional end-user experience – effectively you can use your own feature-set with dedicated hosting.

What is the best approach to take as my website grows?

Quite often it can be disruptive to move a website from one web hosting platform to another as a website grows, but if you are using shared hosting are wanting to grow your website then there will come a point when you will need to upgrade your web hosting plan so that you have the resources available to cope with an increased visitor count. Between shared hosting and dedicated hosting is VPS hosting, which has been created to bridge the gap between the previous two in terms of resources and pricing; however, moving from a shared hosting plan to a VPS server and then on to a dedicated server can cause many issues because downtime could be incurred at certain stages during the process. As your website grows it is recommended that you maximize the resources that are available to you on a shared hosting platform and then complete the migration to a dedicated server because this will only mean one move and will improve the speed in which the transition can be done.

ASP.NET Website on a Dedicated Server

October 2nd, 2012 Comments off

ASP.NET Logo ASP.NET is an enterprise-class scripting framework that can be used for the development of highly scalable and functional web applications that can be hosted on Windows dedicated servers. As ASP.NET is a proprietary technology that has been developed by Microsoft, it is only available with the Windows operating system, although this does provide an array of advantages in terms of performance and features; as there is a close tie between the operating system and the framework, you can be assured more open access to core Windows features that can be used to improve how your web application handles specific tasks and the load that it places on system resources. A dedicated server can handle web applications that are used by thousands of visitors at the same time so combining this with a scripting framework that has been designed to make efficient use of system resources, your web applications won’t be prone to failure because of heavy usage and you should never see any high loads occurring on your dedicated server. Within the dedicated server hosting environment you can always take advantage of other tools such as Microsoft SQL Server that will give you a database backend that you can use with your ASP.NET web applications – this will be inherently important if you are going to be developing scalable and dynamic websites.

Versions of ASP.NET

There are several different versions of ASP.NET that have been released over the years and if you are looking to host an older website on a dedicated server then you will probably need to install an older version of ASP.NET so that your web application functions correctly. Luckily all versions of ASP.NET that have been released are able to work side-by-side on a dedicated server so that Windows web applications of all ages are able to share the same hosting environment. The current version of ASP.NET is 4.5 and this is the recommended framework for you to use if development new ASP.NET applications; older versions include 1.1, 2.0, 3.0 and 4.0 – you should look out for these when choosing any third-party ASP.NET application packages.

IIS Web Hosting

ASP.NET hosting services on a Windows dedicated server are provided by IIS as this is the web server application provided with the operating system and is therefore the only one of its kind capable of serving ASP.NET web pages to visitors. As IIS is also a proprietary application and the only web server with native ASP.NET support, you can be assured of complete compatibility between all of these technologies so that your Windows web applications will function to the best of their ability; furthermore, you can also make your own modifications to improve the efficiency of your website and IIS.

A dedicated server from can provide the perfect breeding ground for any new website because the resources provided will allow you to expand without any limitations. You can also develop your web applications using a number of other technologies and components that won’t be available in the Windows shared hosting environment because you can install any extra features that aren’t offered by default; this means that a Windows dedicated server will represent excellent value for money for all ASP.NET developers.

Microsoft SQL Server Databases

Developing a dynamic website can improve access speeds for your visitors and the way in which you manage your website because all content and configuration information can be stored in one central location that can be accessed from every page and script that is part of your application, as long as there is a connection to the database active. Microsoft SQL Server is a scalable database server solution that can be used for the hosting of databases that have thousands of queries to deal with every minute and underpins some of the busiest websites on the internet; when used in combination with ASP.NET, you can be assured that your web applications have the infrastructure in place that will be able to cope with increases in demand as the number of visitors that you receive improves. MSSQL will perform best when used in a dedicated server environment as you will be able to make a number of different modifications so that the database server functions with your applications in the way that you would like it to.
