IBM System Z

– System Z on IBM
– System Z on Wikipedia

IBM System z, or earlier IBM eServer zSeries, is a brand name designated by IBM to all its mainframe computers.

In 2000, IBM rebranded the existing System/390 to IBM eServer zSeries with the e depicted in IBM’s red trademarked symbol. But because no specific machine names were changed for System/390, the zSeries in common use refers only to one generation of mainframes, starting with z900.

Since April 2006, with another generation of products, the official designation has changed to IBM System z, which now includes both[1] older IBM eServer zSeries, the IBM System z9 models, and the newer IBM System z10 models.

Both zSeries and System z brands are named for their availability — z stands for zero downtime. The systems are built with spare components capable of hot failovers to ensure continuous operations.[2].

Supports the z/OS, Linux on zSeries, z/VM, z/VSE, z/TPF, and MUSIC/SP operating systems.

Models (chronological order)

The older S/390 IBM mainframe servers are considered history since support for the last S/390 compatible version of z/OS (1.5) was dropped on March 31, 2007.[3]

zSeries mainframes:

  • z900 (2064 series), for larger customers (2000)
  • z800 (2066 series), entry-level, less powerful variant of the z900 (2002)
  • z990 (2084 series), successor to larger z900 models (2003)
  • z890 (2086 series), successor to the z800 and smaller z900 models (2004)

System z9 mainframes:

  • z9 Enterprise Class (2094 series), introduced in 2005 initially as z9-109, beginning the new System z9 line
  • z9 Business Class (2096 series), successor to the z890 and smallest z990 models (2006)

System z10 mainframe:

  • z10 Enterprise Class (2097 series), introduced on February 26, 2008
  • z10 Business Class (2098 series), introduced on October 21, 2008

Operating systems for IBM System Z

z/OS

z/OS is a 64-bit operating system for mainframe computers, created by IBM. It is the successor to OS/390, which in turn followed MVS and combined a number of formerly separate, related products. z/OS offers the attributes of modern operating systems but also retains much of the functionality originating in the 1960s and each subsequent decade that is still found in daily use. (Extreme backward compatibility is one of z/OS’s central design philosophies.)

z/OS supports mainframe staple technologies such as CICS, IMS, DB2, RACF, SNA, WebSphere MQ, record-oriented data access methods, REXX, SMP/E, JCL, TSO/E, and ISPF. However, z/OS also supports 64-bit Java, C/C++, and UNIX (Single UNIX Specification) APIs and applications, with UNIX/Linux-style hierarchical HFS and zFS file systems. z/OS can communicate directly via TCP/IP, including IPv6, and includes a standard HTTP server along with other common services such as FTP, NFS, and CIFS/SMB. Another central design philosophy is support for extremely high qualities of service (QoS), even with a single operating system instance, although z/OS has built-in support for Parallel Sysplex clustering.

z/VM

z/VM is the current version in IBM’s VM family of virtual machine operating systems. z/VM was first released in October 2000[1] and remains in active use and development as of 2008. It is directly based on technology and concepts dating back to the 1960s, with IBM’s CP/CMS on the IBM System/360-67 (see article History of CP/CMS for historical details). z/VM runs on IBM’s zSeries, System z9 and System z10 computers. It can be used to support large numbers (thousands) of Linux virtual machines.

Linux on System z

Linux on System z is the collective term for the Linux operating system compiled to run on IBM mainframes, especially System z machines. Other terms with the same meaning include Linux/390, Linux on zSeries, Linux for zSeries, Linux on System z9, zLinux, z/Linux, etc.
