Nowadays, you have a large range of options to choose a processor that meets your demands. Today, we are going to discuss about two models (Intel and AMD). These two models meet all criteria, offers the best affordable price, match the performance ratio, etc … However, you will notice, BODHost.com only included Intel processors. Someone will say we like only Intel, but this is not the case. According our tests AMD does not offer as powerful processors as its cost. Intel processors are pretty ideal for everything such as gaming, streaming videos / audio encoding, graphics, and of course virtualization.
For an instance, Intel Core 2 Quad Q9550. Its 4 cores are driving up the top notch performance. This is really an ideal processor to encode many videos or music. For those who are seeking for game servers, the choice between Q9550 and E8400 is less clear. The frequency of the E8400 (2 cores) is 3GHZ per core against the Q9550′s (4 cores) 2.83 GHz. However, the games who do not take advantage on two core will become faster on dual core.
Even though, Intel Core2 Quad Q9550 2.83 GHz is just an upgraded version of Core 2 Quad Q9400 2.66 GHz. The noticeable differences are frequency and CPU Cache. The Q9550 processor based on Yorkfield chip, and it has 12 MB of L2 cache. On the other hand Q9400 has 6 MB L2 cache. Moreover, Q9550 offers better quality, however, the price ratio is higher than its predecessor.
For your information, BODHost offers both, Intel Core2 Quad Q9400 and Intel Core2 Quad Q9550 dedicated servers. The prices are clearly not the same, but surprisingly many e-commerce stores are regularly showing their interest in these servers.
Undoubtedly, the Q9400 and Q9550 are the most interesting and popular among online business entrepreneurs. So if you are searching a Quad Core Dedicated Server at a reasonable price, you probably know better than me what you have to do …
Dell Quad Core Xeon X5550 2.66 GHz is designed for multiprocessor systems. The architecture consists of four quad core execution units, also called processing units, within a single processor. This processor offers an excellent performance and a high processing capacity for high Internet server loads. Thus, the response time, the number of supported users and scalability improves strongly. This product has been tested and validated by Dell.
These servers can give a whole new portfolio to your business. In addition, servers are available in several formats such as towers, blades, rack mount, workstations, new storage system Equalogic, software and services, etc …
Furthermore, the Dell PowerEdge M series blade servers are basically designed around the Intel Xeon 5500, according to Dell, these servers provide an optimal level of virtualization, easy to use system administration, etc …
With these systems, the web hosting provider can claim the highest level of performance per watt on their dedicated servers.
By providing an integrated administration with a single access point, Dell also claimed that the architecture of their servers offers a purchase price lower than their competitors (specially HP).
Blade Servers -
Dell’s blade servers are mostly popular for the faster deployment than HP and IBM Blade Servers. Additionally, Dell has developed a function ImageDirect, which helps to simplify administration of the image servers and facilitate their development. Companies can create images of servers and ask them to be implemented during during the manufacturing of the server in the factory.
This avoids time consuming manual configuration. Hence, the deployment times are shortened and the time span to operate such servers decreased by almost 45%. The device allows to quickly stabilize such systems during the operation.
Workstations -
Moreover, dell precision workstations are also designed around Intel Xeon 5500 microprocessor, they are characterized by advanced administrative capacity and thermal characteristics.
The new family includes the Dell Precision T7500, T5500 and T3500 tower. These stations were designed for technical applications, media industries, bio sciences etc… All these servers feature the Energy Star 5.0 certification.
Side Software –
The Dell Management Console (DMC), which is borrowed from Altiris and Symantec aims to bring a single point environment to entire administration systems for all computing.
Storage System -
EquaLogic PS6000 storage system provides higher level performance, advanced virtualization abilities and more value to your business. It integrates seamlessly into a storage area network SAN Equalogic to form a virtualized storage.
Dell includes the SAN HeadQuarters solution, which is a centralized dashboard for monitoring performance and the different events of dozens of PS systems, up to 10 PB (petabytes) of storage capacity in a network.
Finally, Dell offers the data center consulting services as well. It allows to evaluate performance of the data center, costs of materials, virtualization of servers, the optimization of backup and restoration.
A plethora of new features should cause IT pros to adopt this much improved version. It is necessary that you can effectively manage your infrastructure Windows Server 2008 R2. The Server Manager console (Server Manager), introduced in the original version of Server 2008, offers a single management environment for almost any task on a server.
Many wizards simplify the configuration of new server roles and features. IT pros can manage most of these tasks from the command line, via servermanagercmd.exe. Since we are talking about the command line, Windows Server 2008 R2 comes with Windows PowerShell 2.0 enabled by default, which is a good thing. With PowerShell management environment, you can manage 500 servers as easily as if there were only five.
Disks with Windows Dedicated Server Hosting
If you need to control disk usage on all these servers, some simple PowerShell commands are enough. There is no need to use scripts. You connect to remote computers via WinRM and you avoid the endless headaches of configuring firewall with WMI (Windows Management Instrumentation). But do not panic, WMI is still present and even easier to use in Windows PowerShell. You can harness the wealth of management information using WMI management features remote WinRM. PowerShell 2.0 will revolutionize your approach to the administration and increase your efficiency.
Windows Server 2008 R2 offers fantastic tools, monitor performance and reliability (Reliability and Performance Monitor). Within minutes, you can get a complete graphical view of your dedicated server and you do not need to go fishing information through a variety of management tools. In the server manager, under Diagnostics, select System Resource Manager (Windows System Resource Manager). It is possible to connect to the local server or remote server. Resource monitor displays an updated status in real time.
The monitor is configurable with standard performance counters of multiple machines. You can also access the Performance tab and run a predefined set of data collection. This approach is convenient to get started and prepare for the creation of their own data sets. After data collection, Windows Server 2008 R2 generates a report containing all relevant information. I personally have never met a simple solution to generate reports of valuable performance and usage.
Among its many features, Windows Server 2008 R2 allows you to define criteria to plan events and windows collection of performance data. And do not think you need to connect to a Windows Server 2008 R2.
In addition you can install Remote Server Administration Tools for Windows 7 and manage all Windows machines 2003, 2008 and Windows Server 2008 R2 without leaving your desk.

Windows Network Load Balancing Dedicated Servers
Network Load Balancer or Clusters that were included in Windows Server OS enabled TCP/IP-based services such as follows:
- Web Services
- Terminal Services
- Virtual Private Networking
- Streaming Media
It basically didn’t require any Hardware Support and distributed IP traffic across cluster hosts which ensures detecting host failures and re-distributes traffic to hosts. It provides control and upgrade from Windows NT 4.0 OS. It delivered high performance and fail-over protection in comparison with other load-balancers.
Financial Transactions, Database access, corporate connections and other functions required more reliability which was offered in Windows NLB. Cluster enabled different servers to manage and operate as a single server increasing availability and management.
Windows 2000 Advanced Server and Data Center Server OS includes cluster technology which also provides fail-over for applications and databases. In terms with NLB, traffic is distributed among multi-node clusters.
Advantages of Network Load balancing servers:
> Network Load Balancer Servers are Scalable based upon the activity it hosts. It always adds more no. of servers when we speak of traffic increase.
> Network Load Balancer Server improves reliability of servers. It detects failure of servers and distributes traffic among servers without interrupting any service.
> It distributes traffic based upon the client’s / Users request.
> In comparison, it’s much better than Round Robin Solutions
> 100% Network Uptime
> Centralized access to all cluster servers
> Cost effective when compared to hardware load-balancing techniques
Installation and Management of Network Load-balancing Dedicated Web Servers:
Network Load Balancer is automatically installed and enabled on the Windows Server 2003 and 2008 Operating System. It’s compatible with Ethernet and network adapters, it doesn’t require any hardware. In a NLB, customer is assigned a IP address which is seen as Virtual IP address which all cluster host respond to. Network Load Balancer load-balances only incoming traffic from all IPs. While configuration of NLB, it’s important that there should be a dedicated IP address, primary IPs and Virtual IP’s in order to enable host TCP/IP to respond to IP addresses. Dedicated IP address is entered first and then virtual IP addresses. Services such as PPTP Server does not allow outgoing connections from a different IP address and cannot be used by dedicated IP.
In a cluster, each host is assigned in range of 1 to 32 where lower no. refers to priority. The default host handles all client traffic for virtual IP addresses. Normally, in this case, if the default host fails, the next priority takes place. Network Load Balancer also customized port rules for range of server ports. It can select either Multiple-host or second hosting load balancing policies. With Multiple-host load balancing, incoming request are distributed among all cluster hosts and load percentage can be specified. In this case, it directs all traffic to most priority server. Rules specified at Ports can block different network access. WHen we speak of port rule multiple-host NLB, one of them is selected in affinity mode and Network Load Balancer client’s traffic from on IP addresses on multiple-cluster hosts. It reduces the load on the servers and increases the response time.
In order to manage client sessions, single-client affinity mode balances network traffic from client’s IP on a single cluster host. Network Load Balancer is configured with single port rule covers all port with multiple-host balancing and single client affinity. It is used for applications.
Network Load Balancer also has remote control program which allows administrators to check status of clusters from cluster host. Network Load Balancer for port rules can be enabled or disabled. New traffic can be blocked on host while TCP connections to complete removing host from cluster. Cluster host can disable remote control.
Applications do not need to be modified for load balancing. It does not directly monitor applications. Network Load Balancer provides application mechanism to monitor cluster. Servers can be removed from the clusters for maintenance without interference with other cluster servers. It also allows custom hardware of software upgrades.
Network Load Balancer scales the performance of server based program. It distributes request among different servers in a cluster. With NLB, each IP packet is received by each host. Cluster host responds to different client requests even multiple request from a single client. Load percentage can be handled with each cluster server and can be set as required depending upon the activity. In case one cluster host fails, the traffic and is re-distributed among other cluster host.
Network Load Balancer uses are fully distributed software architecture. A copy of Network Load Balancer driver runs on each cluster host. Drivers check for all incoming network traffic for cluster IP address. On each cluster host, they act as filter between network adapter drive and TCP/IP stack allowing portion of incoming network traffic. Incoming client request are partitioned and load-balanced among cluster host. Network Load Balancer runs as network driver which is below higher-level application protocol such as HTTP and FTP.
Network Load Balancer can also run as drive between TCP/IP protocol and network adapter drivers within Windows protocol. It maximizes throughput by broadcasting subnet to deliver incoming network traffic to cluster host and removers requirement to route incoming packers to individual cluster host. Filtering packets that are not required can be easily be removed than routed packages, it delivers higher Network Load Balancer throughput than any other solution. As network and speed improve, it improves accordingly and reduces dependencies on hardware. It’s availability in fail-over is another advantage.
Network Load Balancer takes advantage of subnet / switch hub to deliver network traffic to cluster host. It increases the load on switches by accessing additional port bandwidth. However, this is not the concern in many applications. Client-side network switch connections are faster than server-side connection. During packet receiving, Network Load Balancer implements delivery of incoming packages to TCP/IP and receiving other packets by Network adapter driver. It means it will speed up all the processes and reduces latency. In many cases, it removes packet data in memory.
Network Load Balancer uses layer-two broadcast or multi-cast to distribute incoming traffic to cluster host. Network Load Balancer re-assigns MAC address of network adapter for which it is enabled. And cluster host assigned the same MAC address. Incoming traffic received by cluster host and Network Load Balancer driver for filtering. MAC address is taken from cluster IP address in the Network Load Balancer properties.
Cluster host that is attached to switch, it might create MAC address conflict due to layer-two switches to see unique MAC address on all switch ports. In order to avoid these problems, Network Load Balancer modifies MAC address for outgoing packages. This prevents switch from learning the cluster’s MAC address and incoming packets for cluster are delivered to all switch ports. Cluster host connected to hub, Network Load Balancer masking for MAC address in Unicast disables to avoid flooding upstream switches. This is done by setting Network Load Balancer registry parameters MaskSourceMAC to 0.
Network Load Balancer unicast mode has a disadvantage of communication disabling between cluster hosts through cluster adapters. Outgoing packets for cluster host are sent to sender’s MAC address, packages are looped within sender by network stack and they do not reach the wire.
Communication between cluster hosts and host outside the cluster is never affected by NLB’s unicast mode. Traffic for all static IP address are received by cluster host due to the same MAC address. Network Load Balancer doesn’t load balance traffic for the IP address, Network Load Balancer deliver the traffic to TCP/IP on host.
With other cluster host, Load balancing Servers checks it’s traffic as load balanced traffic and deliver to TCP/IP. Network Load Balancing also has another mode by distributing incoming traffic to cluster hosts which is called multi-cast mode. Network Load Balancer – Unicast also increases switch flooding by delivering incoming network traffic to cluster hosts, however this is not the case with multi-cast mode. Network Load balancing have Address Resolution Protocol which is required for the cluster’s main IP and virtual IP address resolving to cluster multi-cast MAC address. Network Load Balancing does not include management of incoming IP traffic other than TCP traffic, UDP traffic, Generic routing encapsulation traffic for each port.
Load balancing dedicated servers offer many features when compared to a dedicated server. Some of them are as follows :
- Asymmetric load : load can be shared with the back-end dedicated server servers. This way, it improves performance on the front-end servers.
- Immediate Activation : In case of failure, the back-end server can immediately brought online.
- SSL Load Management : SSL connections can be managed through load balancing hardware.
- Protection against DDoS : SYN cookies and delayed binds. They can work offline and protects from DDoS counter attacks.
- Compression of HTTP : gzip on web browser to reduce load on the data transfer.
- TCP Offloading / buffer : Every HTTP request has different TCP Connection. It can serve every client that reaches the sever and takes care of every task.
- Caching of HTTP : It can store the data that are static, it reduces the load on the dedicated web server and does not need to retrieve the data everytime.
- Filtering : Traffic management and filtering.
- Security on HTTP : It can hide HTTP error page, remove HTTP response and cookie encryptions in order to maintain high security on servers.
- Priority Que : Differentiating between decent traffic and bad traffic.
- Request Switch : Requests can be sent to different load balancing servers as per URL that is requested.
- Authentication from client : Authentication for clients to access the website.
- Firewall : Un-secured connection to the load balancing servers are prevented and not allowed. This ensures security on the dedicated server.
Load-balancing dedicated servers with affordable prices are the best solutions to remain online always!
Load balancing dedicated server Hosting are one of the most advanced web server solutions used these days as the requirements of client’s are at inclination and in order to manage the requirements, it is important to setup a specification where every activity on the server is distributed accordingly and load has been managed. There are many of load-balancing. Hardware Setup of load-balancing is much costlier when compared to a software load-balancing setup.
Following are few of the ways of setup :
Round Robin DNS Load Balancing dedicated server :
It is basically DNS binded server that load-balances multiple dedicated web servers. This is normally known to be used for group of clusters. Some of the main advantages is that is very simple and can easily be implemented.
The only disadvantage is that the DNS server does not know if any server goes down. It knows only the difference of the IP and does not know by server port. The IP can be cached by others and request will not be forwarded to the other server.
Hardware Load-balancing dedicated server :
Hardware load-balancers route TCP/IP packet to different servers in a cluster. They are highly-reliable but with a cost. It used network gatewat to route traffic. The only disadvantage is that it is cheaper to software versions.
Software Load-balancing dedicated server :
These days, software load balancing dedicated servers are normally used which are integrated with web servers and application servers. They are much cheaper when compared to a hardware load-balancer and can easily be configured as per requirements. Unlike, Round-Robin, it can easily route based on different parameters. It requires additional hardware for complete setup of load-balancer.
