AIX 5L: Multi-purpose server operating system

AIX 5L is an IBM 64-bit UNIX version with strong Linux bias. Specifically for applications, database, and transaction services designed AIX 5L ("L" for Linux) is a versatile server operating system that provides the ability to work together between 32 and 64-bit applications by sharing this performance between file access, memory, and different system services.

The AIX 5L is the product of the Monterey Program, launched in 1999 by IBM, Intel, and Santa Cruz Operation (SCO) to create a unified UNIX product. This operating system can run either on IBM's power-based eserver series servers or on an Itanium (known as Intel Architecture 64) host. A 32-bit binary application that complies with the published AIX binary compatibility Guidelines can be run on the Aix V.4 or Aix v.5 without making any changes.

Aix 5L, based on Aix features, was released in April 2001, incorporating new synergies, Linux, scalability, security, and system management features. Java is designed to embed the OS kernel directly, providing a popular platform programming language for applications. IBM has incorporated a Linux "affinity" in Aix 5L. The retailer sees Linux as an advanced operating system for Low-cost, mainframe computers, and his own Aix is also the primary enterprise server operating system. One of IBM's goals is that this AIX version will not only integrate Linux resource compatibility and Linux applications to support both environments, but also support the evolving Linux standard base (LSB). AIX 5L implements Linux-compliant application programming interfaces (APIs) and header files that provide resource compatibility. By supporting these api,linux applications, you can run on Aix simply by Recompiling.

IBM provides a new file logging system in Aix 5L that can support a larger database. JFS2 can make data storage more compact and designed to reduce space waste. If necessary, you can provide a total of 1000 gigabit (TB) of storage space to the file and file system by extending the schema to 4 petabyte (PTs). As a reference, the previous version of Aix can only handle files with a total of 64GB, so Aix 5L has a huge increase in storage. In addition, the operating system currently supports systems with 32 processors and 256GB RAM.

Security has always been a proud area of AIX, and the same proof can be obtained in this version. AIX is the first 64-bit UNIX operating system to meet the E3/F-C2 and virtual personal Network (VPN) security authentication standards. AIX 5L increases support for the 1.1 version of Kerberos 5 and proves the Recycle list through the Internet Off Exchange (IKE) protocol, which is used to authenticate remote devices or users.

AIX 5L provides improvements to several systems management, especially its workload manager. This handy tool allows administrators to allocate disk I/O, memory, and processor cycles dynamically between jobs, depending on the needs of the application, so that a detailed resource allocation scenario can be identified. The workload manager now supports APIs that allow external applications to adjust system behavior. It also includes a new accounting subsystem that lists the use of resources in the form of a list of reports and objectives.
