  • Page 36: Native Ficon Attachment

    Configuration Planning Native FICON Attachment Native FICON attachment refers to a FICON CPU channel connected to a FICON control unit interface, which may pass through a FICON director (switch). Since the connection is all-FICON, all channels can provide the increased performance of FICON if the attached devices are capable of FICON speeds.

  • Page 37: Ficon Data Transfer Rates

    FICON Data Transfer Rates The fastest native FICON channels are rated at 200 MB/sec., but actually can achieve a maximum data rate of only 170 MB/sec. under optimum conditions. In actual practice, FI- CON typically operates at 40-60 MB/sec. using the 32 KB block size commonly found in tape workloads.

    General Channel Extension Considerations General Channel Extension Considerations Understand Channel Extension Performance Limitations Channel extension usually involves using a WAN (wide-area network), which possibly op- erates at slower-than-FICON speeds. At the very least, the addition of channel extenders will cause additional overhead, and will slow down tape I/O processing. Channel Extenders Are Invisible to Other Devices By its nature, channel extension must look to end devices (hosts, switches, VTSSs, and/or RTDs) as if those were connected to each other without channel extenders;...

  • Page 88 control unit address. The base channel address to which a control unit can respond. conversion. A process that changes the basic capability of a unit in a system and may be a disruptive, requiring a customer to turn over use of the unit to a CSE. Conver- sions may require special tools and higher-level skills of a technical specialist.
  • Page 89 digital. Information stored in binary form that a computer recognizes. For computing use, text, graphics, and sound are stored as digital bits represented by a 0 or 1. Contrast with analog. dimmed text. Dimmed or grayed-out text that appears on a GUI menu and indicates an option is unavailable because the system is not in the mode to use that func- tion, or because software for that function is not installed.
  • Page 90 environmental stress screening (ESS). A method of causing weak components in a machine to fail by apply- ing environmental stresses much greater than normal product environmental specifications, including tempera- ture extremes, temperature shock, and vibration. EPE. Early/External Product Evaluation ERP. See error recovery procedure. error correction code (ECC).
  • Page 91 Fibre Channel (FC). An ANSI-standard serial interface used to provide high-speed data transfers between work- stations, servers, desktop computers, peripherals and, more recently, as a channel for attachment of storage devices. FC allows concurrent communication between connected elements. FC topologies include Fibre Chan- nel-Arbitrated Loop (FC-AL), point-to-point, and switched fabric.
  • Page 92 half-duplex. A communications channel that transmits data in either direction, but only one direction at a time. Contrast with full-duplex. handshake. (1) A signal exchanged between two soft- ware components that uses characters inserted into a data stream to indicate when to start or stop sending da- ta.
  • Page 93 jack. A connector into which a plug is inserted. JBOD. Just a Bunch of Disks. A term used to describe a data storage cabinet that contains only disk storage de- vices, without an internal control unit. A JBOD typically attaches to a host system, which provides control func- tions and intelligence.
  • Page 94 mean time between failures (MTBF). A figure that gives an estimate of equipment reliability. The higher the MTBF, the longer a piece of equipment should last. For example, if MTBF is 10,000 hours, the equipment should run, on average, for 10,000 hours before failing. mean time to repair (MTTR).
  • Page 95 packet. A unit of data formatted for transmission on a network. Each packet has a header containing its source and destination, a block of data content, and an error- checking code. The data packets for a specific message may take different routes to a destination, and the pack- ets are reassembled on arrival.
  • Page 96 relative humidity. The amount of moisture in the air, as compared with the maximum amount of humidity that the air could contain at the same temperature; expressed as a percentage. relocation. The process of physically moving VTSS units within a same site or immediate area without the use of packing materials.
  • Page 97 support facility. VTSS functionality provided by ISP cards and support facility software that enables human interface with a VTSS for monitoring, communication, and testing. synchronous. (1) Synchronized by a common timing signal. (2) Occurring with a regular or predictable time re- lationship.
  • Page 98 VTCS. Virtual Tape Control System. In VSM, primary host software that controls activity and coordinates oper- ations between the host operating system and the VTSSs, VTVs, RTDs, and MVCs, as represented in front-end tape drives or libraries and back-end disk ar- rays.
