(Note: Microsoft has terminated support for Windows Server 2003 and it is advisable to consider upgrading from this legacy OS to an up-to-date version of Windows Server. If your organization is considering moving up to Windows Server 2012 R2 or Windows Server 2016, Progent can provide online and onsite Windows Server 2012 R2 planning and configuration consulting services or Windows Server 2016 disaster recovery consulting to ensure your project finishes on time and within budget. In addition, Progent's Windows Server Failover Clustering Consultants can help you a configure and troubleshoot a high-availability clustering solution based on Microsoft's latest technology.

Fault Tolerant Server Clustering ConsultingEven with typical fault tolerant feature found in high-end server hardware, such as redundant power supplies and mirrored or RAID 5 disk arrays, failed devices must be identified and replacement components must be procured and installed. These failures can bring down a server for hours, if not days. Furthermore, during regularly scheduled software maintenance functions, servers need to be rebooted or brought off-line for an extended period. For customers who need 100% uptime, the only solution is to deploy a clustered server configuration that provides fully redundant servers for a single application.

A server cluster is a group of independent computers that work together to provide a common set of services. Windows 2003 provides this high-availability solution with the Cluster service. If a cluster node (a computer in a cluster) fails, other nodes in the cluster assume the functions of the failed node. Server clustering is an essential piece of any fault-tolerant architecture, and making large investments in communication infrastructure redundancy without providing for server redundancy defeats the value of that investment.

Progent offers Windows 2003 Server consulting to help your company implement clustered server configurations that can potentially provide 100% uptime, even for normal maintenance functions. This high-availability is possible because a single server in a cluster can be brought off-line for maintenance work without affecting users. Clustering also allows IT personal to perform critical security updates during regular business hours without reducing user productivity.

Microsoft Windows 2003 Server offers mature clustering technology. This is the third major release of Microsoft clustering technology, which was first released in 1997. Microsoft Windows Server 2003, Enterprise Edition, and Windows Server 2003, Datacenter Edition, present a single view of the server to users, applications, and the network and both versions of Windows Server 2003 support up to eight-node clusters. Failover clustering configurations can be built around Microsoft technologies for mission-critical and collaborative applications such as Microsoft Exchange, Microsoft SQL Server file and print services.

Host Clustering with Microsoft Virtual Server
Virtual Server host clustering is a technique for enhancing the capability of Microsoft Virtual Server 2005 with the server cluster support incorporated in Microsoft Windows Server 2003. By means of Virtual Server host clustering, your network can benefit from an array of services via a minimum number of actual hardware servers and, simultaneously, ensure the high availability of the provided services. In case one server requires scheduled or unscheduled downtime, another server can immediately take its place and begin supporting services. As a result, your clients experience minimal service disruption. Progent's Microsoft-certified network engineers have in-depth experience deploying and supporting Microsoft Virtual Server. For more information, refer to Consulting Services for Microsoft Virtual Server.

Server Clustering and Storage Area Networks
A storage area network (SAN) is a set of disks, tapes, and servers connected to a common infrastructure, or storage fabric, such as Fibre Channel. A SAN allows multiple servers to access a common pool of storage. This allows storage to be assigned dynamically from the pool whenever it is required. Storage on a given server can be increased or decreased as needed without complex reconfiguring or re-cabling of devices. SAN technology is a good way to build clusters where shared access to a data set is required. By deploying multiple clusters onto a single storage area network, all of the benefits of SAN technology can be brought to the cluster environment. Progentís Microsoft certified engineers can show you how to combine Microsoftís server cluster technology with storage area networking to make your network more fault tolerant and easier to manage.

Server Clustering with Microsoft Exchange
Messaging systems based on Microsoft Exchange are vital for many businesses. Unfortunately, this crucial function is vulnerable to component failure, power loss, operator errors, and natural disasters. By allowing the failover of resources, server clustering provides fault tolerance for an Exchange environment. Server clusters that use the Microsoft Cluster Service can maintain data integrity and provide failover support and high availability for mission-critical applications and services on your back-end servers, including messaging systems, databases, and file and print services.

This figure shows an example of a four-node Exchange cluster with three active nodes and a passive standby node:
