Executive SummaryIf you’ve begun using Internet technologies in your business, you know how important it is to have your servers available all the time. With so much work relying on Internet and intranet processes, if your system isn’t running, chances are your employees are idle and your customers and partners aren’t able to reach you. That’s why maximum reliability and availability was one of the most important Windows 2000 development goals. The result: Windows 2000 is the most reliable operating system Microsoft has ever produced. A common IT industry term for maximum reliability is “five nines,” meaning that a server is running 99.999 percent of the time. (Which translates into just 5 minutes downtime over a year.) Although most businesses do not need such stringent uptime requirements, a system built on Windows 2000 Datacenter Server can meet this level of reliability. This paper provides an overview to help you understand how to get the most from these features in your business. First, it highlights the reliability and availability features integrated throughout the Windows 2000 Server family of operating systems. Next, it shows how you can achieve greater availability using the clustering and load balancing features in Windows 2000 Advanced Server. Then, it explains how Windows 2000 Datacenter Server expands on these features to deliver an operating system that meets the highest levels of reliability and availability. Beyond the technology improvements in Windows 2000, Microsoft has also invested in tools and training resources to help customers create an IT environment that supports reliable operations. Industry studies show that as much as 80 percent of system failures can be traced to human errors or flawed processes. Everyone knows someone who lost vital information because they forgot to do a backup. This is the classic example of the kind of problem a rigorous IT operations environment can help avoid. Simply moving to Windows 2000 will improve system reliability. But getting the most out of the operating system relies on a combination of reliable technology, well-trained people, and sound operations. To create this environment, organizations can supplement the operating system technology with:
TechnologyReliable systems start with reliable server software. The Microsoft Windows 2000 Server family of operating systems share a core set of architectural features aimed at ensuring continued reliability and availability.
How Windows 2000 Advanced Server Increases AvailabilityThe Windows 2000 Advanced Server operating system contains all the functionality and reliability of Windows 2000 Server, plus additional features for applications that require higher levels of scalability and availability. Windows 2000 Advanced Server lets you readily increase your server capacity to keep pace with business growth, and it increases the availability of your important systems. Increasing Server AvailabilityServer downtime caused by hardware or software failures can result in lost revenue, wasted IT staff work, and unhappy customers. To address these concerns, there are two kinds of technology used to increase server availability in Windows 2000 Advanced Server: Clustering and Network Load Balancing (NLB). Windows Clustering links individual servers so they can perform common tasks. If one server stops functioning, two-node failover-support transfers its workload to the other server. NLB works by spreading client requests among various servers that are linked together to support a particular application, ensuring a server is always available to handle requests on your Web site or communications network. The clustering services in Windows 2000 Advanced Server let you sustain productivity and ensure customer satisfaction by increasing the load your server infrastructure can reliably handle. How Datacenter Server Increases Reliability and AvailabilityWindows 2000 Datacenter Server is for companies with uncompromising reliability requirements. It includes all the features in Advanced Server and adds expanded server capacity and clustering to maximize reliability and availability. Only original equipment manufacturers (OEMs) that meet a stringent set of hardware and software guidelines can offer Windows 2000 Datacenter Server. This certification requirement combined with the most advanced reliability and availability features delivers an OS designed to meet the needs of large data warehouses, online transaction processing (OLTP), and server consolidation. Maximizing Availability with 32 SMP and 4-Node ClusteringDatacenter Server scales up to 32-way symmetric multiprocessing (SMP) and up to 64 gigabytes (GB) of physical memory, compared with up to 8-way SMP and 8GB of memory in Windows 2000 Advanced Server. In addition, Datacenter Server supports four-node failover, compared with two-node failover support in Advanced Server. High Performance with WinSock DirectWinSock Direct enables efficient high-bandwidth, low-latency messaging that conserves processor time for application use. In system area networks (SAN), this allows more users on the system, providing faster response times and higher transaction rates. Managing Critical Resources with the Process Control ToolProcess Control is a powerful, flexible tool that helps you manage and control the resources that processors use on your system by applying rules that you define. When adjusted to fit the design of an application, Process Control helps ensure predictable and stable operations.
