5.3.4 z990 cryptographic feature codes

Following is a list of the cryptographic features available with the z990.

Feature code

Description

3863

Crypto enablement

 

Crypto enablement feature. Prerequisite to use the CPACF, PCIXCC, and

 

PCICA hardware features.

0868

PCIX Cryptographic Coprocessor (PCIXCC) feature

0862

PCI Cryptographic Accelerator (PCICA) feature

0886

TKE hardware for Token Ring

 

TKE workstation hardware with Token Ring connection, DVD drive, and

 

17-inch monitor.

0851

TKE 4.0 code

0852

TKE 4.1 code (available May,2004)

0889

TKE hardware for Ethernet

 

TKE workstation hardware with Token Ring connection, DVD drive, and

 

17-inch monitor.

0851

TKE 4.0 code

0852

TKE 4.1 code (available May, 2004)

The z990 requires TKE Version 4.0 or 4.1 code. In case a z900 with a TKE 3.x workstation is upgraded to a z990, the TKE Version 3.x workstations can be retained to control other servers, but cannot be used on the z990. To control the z990 TKE Version 4.0 or 4.1code is required.TKE 3.x workstations that are carried forward are automatically updated to the 4.1 TKE code when a PCIXCC feature is ordered or present on the sever.

The TKE Version 4.0 or 4.1 code supports all models back to CCF support on a G3 CMOS processor.

TKE 4.1 code provides local and a remote key entry with a master key.

Note: The z990 (and the z890) are the last zSeries servers offering Token Ring adapters on the Trusted Key Entry (TKE) workstations.Timely planning is advised in preparation of migration to the Ethernet environment.

990 specifications

The IBM 990 series, often referred to in the context of IBM's pioneering efforts in the realm of mainframe computing, represents a unique chapter in the history of information technology. Introduced in the late 1960s, the IBM 990 series was designed as a powerful tool for enterprise-level data processing and scientific calculations, showcasing the company's commitment to advancing computing capabilities.

One of the main features of the IBM 990 was its architecture, which was built to support a wide range of applications, from business processing to complex scientific computations. The system employed a 32-bit word length, which was advanced for its time, allowing for more flexible and efficient data handling. CPUs in the IBM 990 series supported multiple instructions per cycle, which contributed significantly to the overall efficiency and processing power of the machines.

The technology behind the IBM 990 was also notable for its use of solid-state technology. This provided a shift away from vacuum tube systems that were prevalent in earlier computing systems, enhancing the reliability and longevity of the hardware. The IBM 990 series utilized core memory, which was faster and more reliable than the magnetic drum memory systems that had been standard up to that point.

Another defining characteristic of the IBM 990 was its extensibility. Organizations could configure the machine to suit their specific needs by adding memory, storage, and peripheral devices as required. This modular approach facilitated the growth of systems alongside the technological and operational demands of the business environments they served.

In terms of software, the IBM 990 series was compatible with a variety of operating systems and programming environments, including FORTRAN and COBOL, enabling users to access a broader array of applications. This versatility was a significant advantage, making the IBM 990 an appealing choice for educational institutions, research facilities, and enterprises alike.

Moreover, the IBM 990 was engineered to support multiprocessing, which allowed multiple processes to run simultaneously, further increasing its effectiveness in tackling complex computing tasks.

In summary, the IBM 990 series represents a significant advancement in computing technology during the late 20th century. With a robust architecture, versatile configuration options, and a focus on solid-state technology, the IBM 990 facilitated substantial improvements in data processing capabilities, making it a cornerstone for many businesses and academic institutions of its time. Its impact can still be seen today in the continued evolution of mainframe computing.
