IBM WebSphere Performance Pack Server

Based on the effectiveness, availability and scalability of Internet services as a whole, the use of Webspherep erformancepack in the system can provide dynamic load balancing, page caching, and other services, the main features are as follows:

· Meet the QoS after system expansion

· Improve content accessibility during file replication

· Increase system throughput and availability through dynamic load balancing

· Reduce the occurrence of "unable to connect to server" error messages

· Bandwidth savings and operating costs through advanced caching algorithms

· Flexible proxy proxy function, including pics content filtering

· Increase customer satisfaction with excellent scalability and functional distribution, processing millions of requests from thousands of browsers per hour.

Quality of services (Quality of service)

What does QoS mean to you? In addition to performance, you may also consider availability, cost, efficiency, scalability or meet your specific requirements. Using the W ebsphere Performance pack You can easily optimize your concerns. It can adjust the peak state of our B server. It enables Web server to reduce congestion, increase content availability, and improve webserver performance. Similarly, web managers need to schedule servers, application platforms, and other parts to be maintained without disrupting system services.

Increase availability

An important factor in the quality of service is the ability to access the required information or services within the desired response time. For business users who want to provide applications and information over the Internet, this means their sites need to be serviced by their users-usually 24x7 (24 hours a day, 7 days a week). What does this mean to you? This means that the performance of the quality of service will be closely related to the type of service provided by the service provider and the area covered by the services. The performance packs in our Bsphere can help ISPs and their technical experts provide quality-assured network connectivity, routing backups, bandwidth and network access to different levels of users, while providing reliable authentication services and registration management for users through simple management tools.

Scalability

The performance pack contains the latest Internet technology. It leverages the following features to meet growth availability and scalability requirements:

Multi-platform caching and proxy servers, providing excellent performance and enhanced proxy services

A more flexible file management system that provides Cross-platform file storage management and non-disruptive replication and high availability for distributed server environments.

Multi-platform Load balancing scheme is provided for load balancing of HTTP,FTP or other TCP services.

Load balancing (balancing load)

Users can define rules by performance packs. Based on rule-based load balancing, you can decide when to send packets to which server. Rule-based traffic routing can provide different service levels for a specific user. The Performance Packs load Balancing feature helps users manage large volumes of information and electronic transactions on local and wide area networks. This TCP (UDP) connection router and associated load management software support a variety of background servers. The load balancing function can connect multiple independent servers, logically become a server to provide services externally, greatly improve the access capability, to meet the access of a large number of users. This Web server provides a unified IP address, and the function is independent of the domain name server, can improve the usability and flexibility of the system scalability. The "Sticky" port features the ability to help users who need to maintain an existing connection and then connect to the same server. The advantage of this feature is that the application server delivers the response directly to the user without the need for a load balancer.

Customized caching

When you receive a large file, can it replace the current another file or a file smaller than it? How can you avoid caching files that are too old? After all, the stored files not only read faster, but also the content should be up to date. Performance Pack caching P Roxy Server enables administrators to use caching parameters to accelerate response times. The cached content is purged by the refresh requirement and the least access method (Lea St-cost-to-retrieve) rather than the least recently used (LRU) algorithm. It also uses the pics (PLA tform for Internet Content Selection) filter to filter content. The administrator can also provide client anonymity by configuring the proxy server to hide specific domains in the HTTP headers contained in the client's IP address. Caching server also includes a cache agent to assist with setup and maintenance. The flexible socksification feature allows the user to control the path of the request URL. The Caching server is HTTP1.1 compatible, so it can support persistent connections.

File Sharing and Management

Some customers want to share information on a global scale. Ensure consistency of information on different platforms and locations, and establish appropriate protection for access. The Distributed File service in the per Formance pack allows access to the home page files from anywhere in the system with strong reliability, availability, functionality, and security. By replicating this information to a different location on a file server and then caching it on a Web server, a large number of Web sites can send a large number of high-performance and complete information to thousands of users. File replication and load Balancing enable server maintenance to work during normal working hours without disrupting work. To achieve more effective operation and improve customer service. The cost of Distributed File Service management is reduced when each file has a unique name throughout the system. This naming method allows administrators to easily add or reconfigure resources to improve access to information in a flexible, plug-and-play environment.
