	Channel type		CHPID definition	MIF shared channel	MIF spanned channel

	IC	internal	ICP	yes	yes

	HiperSockets	internal	IQD	yes	yes

Note that while the PCICA and PCIXCC cryptographic features do not have CHIPD types and are not identified as spanned channels, all logical partitions in all LCSSs have access to the PCICA feature, up to 30 logical partitions per feature, and all logical partitions in all LCSSs have access to the PCIXCC feature, up to 16 logical partitions per feature.

I/O features cables and connectors

Attention: All fiber optic cables, cable planning, labeling, and installation are customer responsibilities for new z990 installations and upgrades. Fiber optic conversion kits and Mode Conditioning Patch (MCP) cables are not orderable as features on z990 servers. Only ICB (copper) cables are orderable. All other cables have to be sourced separately.

IBM Fiber Cabling Services offer a total cable solution service to help with your cable ordering needs, and is highly recommended. These services take into consideration the requirements for all of the protocols/media types supported on zSeries, (for example, ESCON, FICON, Coupling Links, OSA), whether the focus is the data center, the Storage Area Network (SAN), Local Area Network (LAN), or the end-to-end enterprise.

The Enterprise fiber cabling services employ the use of a proven modular cabling system, the Fiber Transport System (FTS), which includes trunk cables, zone cabinets, and panels for your servers, directors, and storage devices.

FTS supports Fiber Quick Connect (FQC), a fiber harness integrated in the zSeries frame for “quick” connect, which is offered as a feature on zSeries for connection to ESCON channels.

Whether you choose a packaged service or a custom service, high quality components are used to facilitate moves, adds, and changes in the enterprise to prevent extending your maintenance “window”.

Table 3-9lists the required connectors and cable types for each I/O feature on z990 servers.

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.
