  • Page 15: Switch Description

    General InformationI The HP StorageWorks Edge Switch 2/24 provides dynamic switched connections between Fibre Channel servers and devices in a storage area network (SAN) environment. SANs introduce the concept of server-to-device networking and multi-switch fabrics, eliminate requirements for dedicated connections, and enable the enterprise to become data centric.

  • Page 16

    General InformationI The switch, shown in Figure 1–1, provides dynamic switched connections for servers and devices, supports mainframe and open-systems interconnection (OSI) computing environments, and provides data transmission and flow control between device node ports (N_Ports) as dictated by the Fibre Channel Physical and Signaling Interface (FC-PH 4.3).

    Glossary ordered set In Fibre Channel protocol, four 10-bit characters (a combination of data and special characters) providing low-level link functions, such as frame demarcation and signaling between two ends of a link. It provides for initialization of the link after power-on and for some basic recovery functions.

    Glossary persistent binding A form of server-level access control that uses configuration information to bind a server to a specific Fibre Channel storage volume (or logical device), using a unit number. See also access control. personal computer PC. A portable computer that consists of a system unit, display, keyboard, mouse, one or more diskette drives, and internal fixed-disk storage (D).

    Glossary principal switch In a multiswitch fabric, the switch that allocates domain IDs to itself and to all other switches in the fabric. There is always one principal switch in a fabric. If a switch is not connected to any other switches, it acts as its own principal switch. printed wiring assembly PWA.

    Glossary protective plug In a fiber-optic environment, a type of duplex connector (or cover) that provides physical protection (D). Contrast with loopback plug. protocol (1) Set of semantic and syntactic rules that determines the behavior of functional units in achieving communication. (2) In systems network architecture, the meanings of and sequencing rules for requests and responses for managing the network, transferring data, and synchronizing network component states.

    Glossary read-only memory ROM. An information storage chip with permanent memory. Stored information cannot be changed or deleted except under special circumstances (D). Contrast with random access memory. redundancy Performance characteristic of a system or product whose integral components are backed up by identical components to which operations will automatically failover in the event of a component failure.

    Glossary SFP transceivers small form factor pluggable transceivers. shortwave Lasers or light-emitting diodes (LEDs) that emit light with wavelengths around 780 nm or 850 nm. When using multimode fiber (50 nm) shortwave lasers can be used with Fibre Channel links less than 500 m. To achieve longer lengths, single-mode fiber is required. The preferred fiber core size is 50 micron as this fiber has large bandwidth so that the distance is limited by the fiber attenuation.

    Glossary singlemode optical fiber An optical fiber that allows one wavelength-dependent mode (light path) to propagate. Contrast with multimode optical fiber. small computer system interface SCSI. An interface standard that enables computers to communicate with peripherals connected to them. Commonly used in enterprise computing and in Apple Macintosh systems. Usually pronounced as “scuzzy.”...

    Glossary static random access memory SRAM. SRAM is microprocessor-cache random access memory. It is built internal to the microprocessor or on external chips. SRAM is fast, but relatively expensive (D). Contrast with dynamic random access memory. storage area network SAN. A high-performance data communications environment that interconnects computing and storage resources so that the resources can be effectively shared and consolidated.

    Glossary System Automation for Operating System/390 SA OS/390™. IBM licensed software that provides System/390 Parallel Sysplex™ management, automation capabilities, and integrated systems and network management. SA OS/390 manages host, remote processor, and I/O operations. SA OS/390 integrates the functions of Automated Operations Control for Multiple Virtual Storage (MVS™), ESCON™ Manager, and Target System Control Facility (D).

    Glossary terabyte TB. One thousand (1,000) gigabytes; one terabyte of text on paper would consume 42,500 trees. At 12 characters per inch, 1 TB of data in a straight line would encircle the earth 56 times and stretch some 1.4 million miles equalling nearly three round trips from the earth to the moon.

    Glossary UNIX A popular multi-user, multitasking operating system originally designed to be a small, flexible system used exclusively by programmers. UNIX was one of the first operating systems to be written in a high-level programming language, namely C. This meant that it could be installed on virtually any computer for which a C compiler existed.

    Glossary virtual storage VS. (1) Storage space that may be regarded as addressable main storage by the user of a computer system in which virtual addresses are mapped to real addresses. The size of virtual storage is limited by the addressing scheme of the computer system and by the amount of auxiliary storage available, not by the number of main storage locations.

    Glossary wrap plug Synonym for loopback plug. wrap test A test that checks attachment or control unit circuitry, without checking the mechanism itself, by returning the output of the mechanism as input. A wrap test can transmit a specific character pattern through a system and compare the pattern received with the pattern transmitted (D).
