Eserver Ibm

In 1988, IBM introduced the AS400 ® as a server solution for midsize businesses and departments within large enterprises. Over time, IBM realized that, to achieve their vision for the PC and Unix servers across organizations worldwide, the AS400 would need to be easily integrated with distributed networks and applications web. To accomplish this, IBM redesigned the use of AS400 eServer ® i5 servers with POWER5 processors, the AS400 and rebranded as IBM iSeries ®.

The strategic iSeries features include:

- Integration
- Virtualization
- Optimization
- Security
- Support for a wide range of mediums application development
- Simplified Administration
- Scalability

Integration

ISeries includes an integrated standards-based for the DB2 database management of corporate data. ISeries includes an integrated HTTP server and Apache web server for web-based deployment, and a Java/J2EE environment services web application development web. Many are also popular development technologies integrated with the iSeries, including SQL, MySQL,. NET, DRDA / CLI, ODBC and JDBC. Windows, UNIX and NFS file system are supported.

Virtualization

iSeries virtualization allows organizations to manage multiple applications and processes integrated with the operator, shared processor pools and automatic balancing.

Optimization

The cluster architecture, transaction recording and mirroring iSeries capacity to provide the flexibility and reliability. IBM integrates tools for managing the cluster.

Security

The model safety for the IBM iSeries is the object-based, which simplifies implementation and improves the system's ability to resist viruses. ISeries can not only detect intrusion, but has built in methods to prevent and provide an audit log to monitor potential security risks. Both the production and backup data is encrypted, and SSL VPN used to ensure the network is secure.

Application Development

With support for services oriented architecture (SOA), IBM Rational development tools, application runtime and UNIX, iSeries offers a myriad of options for application development. Languages supported include C iSeries, RPG, COBOL, C + +, Java, EGL, PHP and CL.

Administration

Storage management is integrated into the system and the host system managed storage for I, AIX, Linux, Windows and VMware. The module administration of web-based for easy access. IBM Systems Director provides a single, consistent user interface for managing both physical and virtual systems.

Scalability

With most systems, the system is integrated with the machine interface technology, which means that updates are dangerous to each day's activities. With iSeries, however, updates are automatic, and the separation of interface technologies makes the process practically perfect. With IBM Capacity on Demand feature, you can only activate processors and memory that you need, making iSeries scalable, flexible and cost efficient.

Communication

To communicate with IBM iSeries AS400 or from your Windows PC, you must use a terminal emulator. Terminal emulators intercept and translate the 5250 data stream so that your PC can understand, view and manipulate. One of these is the terminal emulator Zephyr passport, which provides TN5250 emulation and tn5250e.

Conclusion

The key to the success of the iSeries AS400 was the integration of relational databases, security, web services, network and storage management. According to IBM, more than 5000 solutions ISVs are supported on iSeries. Virtualisation allows companies to run several applications simultaneously, allowing the organization to make the most its resources.
