iSeries (i5, i5 Series)

iSeries is IBM's midrange server line, designed for small businesses and departments in large enterprises. The product line, formerly known as AS/400 (still the preferred name among many long-time users ), was renamed in 2000 with the introduction of the V5R1 operating system and 800 line of servers. i5 is the latest hardware evolution of one of IBM's most widely-installed product lines. iSeries servers use IBM's Power5 microprocessors and are capable of running five different operating systems at the same time (AIX, Windows, Linux, OS/400, and i5/OS) on multiple partitions. IBM also offers p5 (or pSeries) servers for large enterprise users who want to run Unix systems or who need more scalability.

According to Chief Scientist IBM iSeries, Dr. Frank G. Soltis, the iSeries is used by businesses all over the world, is sold in more countries than McDonald's hamburgers, and has the largest number of customers of any IBM server.

Search400.com expert John Brandt explains the advantages of upgrading from AS/400 hardware to the i5:

  • 64-bit and 128-bit computing
  • Better performance than the AS/400 system
  • Hardware management across all partitions from a single device
  • Hardware sharing, including tape backup, across all operating systems
  • Support for single signon across any Kerberos-compatible system

The release of IBM i 7.4 and DB2 Mirror

The year 2019 saw the release of IBM i 7.4 with more updated features to handle massive workloads. This new version has been rolled out with many new features like security, application development, and accessing IBM i. The security feature in 7.4 version is ‘by object’ which means the object ability allows the clients to know how a particular object is being used by all the users. The object feature even helps the client to find out the authority of the users as they access the object. This ultimately leads to locking the objects which the client wants to lock and uninterrupted security.

IBM i 7.4 has a lot to offer beyond security too. The application development and updates in RPG and COBOL require the implementation of 7.4 version.

IBM DB2 Mirror is the solution to get rid of any type of server downtime. Industries like banking and finance cannot afford server discrepancies hence the release of DB2 Mirror is a sigh of relief for them. With this product, clients can connect the two power systems and then the two systems present their DB2 databases as if they are one database spread across the two systems. This showcases that if the client wants to use DB2 on both the systems they can easily do it. DB2 mirror allows the database functions like insert, delete and update to be applied simultaneously on both the systems. The two systems sharing the same database can use the same applications at the same time.  Source: Current State of IBM i Systems
