1 Planning and Implementation Overview This chapter provides an overview of key participants, timelines, and activities involved in planning for and implementing a VSM5 system. Successful implementation requires regular communication and coordination between customer personnel and the Sun account team. This ongoing collaboration helps ensure that all factors critical to the implementation are identified and addressed before equipment is delivered to the site.
Planning and Implementation Overview ■ Creating Planning Teams Once a sales proposal has been accepted, the Sun customer service manager (CSM) should confer with customer-site personnel including the network administrator, data center manager, and facilities manager to identify which individuals who should be involved with implementation planning, site readiness planning, and delivery and installation planning.
Planning / Readiness / Implementation Timelines ■ Planning / Readiness / Implementation Timelines The following activity guidelines allow sufficient time for planning, readiness, and implementation tasks to be completed prior to delivery of VSM5 system equipment to a customer site. 1.
Planning and Implementation Overview • The dock manager and/or facilities manager and Sun customer service manager identify any special shipping requirements, and notify the Sun manufacturing group as needed. • The Sun sales representative completes and submits the equipment sales order, including all necessary cabling and spare parts.
Configuration Planning 2 This chapter provides an overview of configuration planning considerations and activities that are used to design a VSM5 system tailored to customer requirements, and to ensure proper implementation of the system.
Configuration Planning ■ Defining Customer Requirements Customized tools are available to assist Sun personnel with estimating customer requirements and configuring a unique VSM5 system to meet those needs. VSM Quick is a pre-sales tool package designed for use by SEs and ARs. It provides potential customers with a quick estimate of the size and scope of a VSM5 system that is tailored to their requirements. VSM Quick and other VSM-related tools are available on the SE Tools website at http://setools.
Defining Customer Requirements VSM Sizer Tool As shown in Figure 2-2, the VSM Sizer tool requests inputs on mount activity, file size, the estimated growth rate of data, and the current configuration of libraries, transports, and cartridges to determine customer requirements for a VSM5 system. Based on the results of its calculations, the tool identifies an optimum VSM5-VTSS configuration and minimum number of RTDs to meet the defined requirements.
Configuration Planning MVC Sizer Tool As shown in Figure 2-3, the MVC Sizer tool estimates the number of Multiple Volume Cartridges (MVCs) required for a VSM installation at intervals of 90 days, 180 days, 270 days, one year, two years, and three years, based on mount activity and average file size. The tool also reports estimated hours needed for daily reclaim activity, and the average number of MVCs to be added on a monthly basis after the first 90 days. Figure 2-3.
Defining Customer Requirements MVC Migration Tool As shown in Figure 2-4, the MVC Migration tool evaluates existing tape systems, tape media, channels, and data set size to estimate the number of Multiple Volume Cartridges (MVCs) required for a VSM installation at intervals of 90 days, 180 days, 270 days, one year, two years, and 3 years, and the amount of time needed to migrate data from existing manual or Nearline tape devices to the proposed VSM5 system. Figure 2-4.
Configuration Planning CDS Sizer Tool As shown in Figure 2-5, the CDS Sizer is used to determine size requirements for the HSC control data set (CDS) based on a specific VSM5 system configuration. The tool requests detailed inputs about the VSM configuration (number of LSMs, VTVs, MVCs, VTSSs, configured MVC ranges, and configured VTV ranges), then calculates the number of 4K blocks needed in the HSC database to accommodate the LSM and VSM configurations. Figure 2-5.
VTSS Configuration Planning ■ VTSS Configuration Planning A VSM5 system consists of Virtual Tape Control System (VTCS) host software, Virtual Tape Storage Subsystem (VTSS) disk hardware (tape buffers)1, real tape drives (RTDs) which attach to an Automated Cartridge System (ACS), and automated cartridge systems (ACSs), a.k.a. tape libraries. A VSM5-VTSS connects to IBM S/390-equivalent data-streaming architectures and related hardware2, and has front-end and back-end FICON connections.

VTSS Configuration Planning Prerequisites for FICON Connectivity Note: VTCS 5.1 code or later and VTSS code D01.01.00.17 or higher are required prerequisites for enabling front-end FICON connectivity between a VTSS and mainframe (host) CPU or FICON director. VTCS 6.0 code or higher and VTSS code D01.02.00.00 or higher are required prerequisites for enabling back-end FICON connectivity between a VTSS and RTDs or cluster-links (Clinks).
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. Figure 2-6 illustrates the two attachment modes for native FICON: direct and switched.
VTSS Configuration Planning 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, FICON typically operates at 40-60 MB/sec. using the 32 KB block size commonly found in tape workloads. VCF3 cards support 2 Gb link speeds; actual throughput speed is determined by many factors including block size, microcode level, etc. FICON Cabling — Short-Wave vs.
Configuration Planning VCF3 (FICON) Card Configuration Examples Note: VCF3 (FICON) cards must be installed and removed in pairs. A minimum VSM5VTSS configuration requires four VCF3 cards. Cards must be removed in the reverse order they were installed. Although there is no mechanism to restrict or support which slots VCF cards are placed in, configurations other than those shown in Figure 2-7 through Figure 2-9 will not be supported.
VTSS Configuration Planning As shown in Figure 2-8, six VCF cards provide 12 physical FICON ports, and each port supports 64 host paths (768 paths total). Cards must be installed in the slots shown (i.e., the third VCF3 card pair must be installed in slots VCF01 and VCF11).

Implementation Planning 3 This chapter provides an overview of implementation planning activities and tasks, which are designed to ensure a VSM5 system is properly configured, tested, and certified according to customer requirements. Table 3-1 provides an overview of high-level activities, sub-tasks, and participants encompassed by the implementation planning process. Table 3-1.
Implementation Planning The implementation planning process is designed to identify and schedule completion of configuration, performance tuning, and performance testing activities for a VSM5-VTSS after it has been physically installed at a site. A team comprised of key customer personnel (systems administrator; network administrator; data center manager, system operator, etc.) and Sun Professional Services personnel (technical support specialist; systems engineer; customer service manager, etc.
4 Site Readiness Planning This chapter provides information about activities designed to ensure the site is equipped to accommodate the power, safety, environmental, HVAC, and data handling requirements of VSM5 system equipment. Table 4-1.Site Readiness Planning Overview Key High-Level Activities • Select site readiness team members, and define roles and responsibilities.
Site Readiness Planning ■ Site Evaluation – External Considerations Several months before delivery of VSM5 system equipment, a readiness planning team should identify and evaluate all external site factors that present existing or potential hazards, or which could adversely affect delivery, installation, or operation of the system.
Site Evaluation – Internal Considerations Transfering Equipment Point-to-Point Site conditions must be verified to ensure all VSM5 system equipment can be safely transported between the delivery dock, staging area, and data center without encountering dimensional restrictions, obstructions, or safety hazards, or exceeding rated capacities of lifting and loading equipment, flooring, or other infrastructure. Conditions that must to be verified are described below.
Site Readiness Planning Data Center Safety Safety must be a primary consideration in planning installation of VSM5 system equipment, and is reflected in such choices as where equipment will be located, the rating and capability of electrical, HVAC, and fire-prevention systems that support the operating environment, and the level of personnel training. Requirements of local authorities and insurance carriers will drive decisions as to what constitutes appropriate safety levels in a given environment.
Site Evaluation – Internal Considerations Site Power Distribution Systems The following elements of the site power distribution system should be evaluated when planning an installation of VSM5 system equipment. System Design A properly installed power distribution system is required to ensure safe operation of VSM5 system equipment. Power should be supplied from a feeder separate from one used for lighting, air conditioning, and other electrical systems.
Site Readiness Planning Equipment Grounding For safety and ESD protection, VSM5 system equipment must be properly grounded. VTSS cabinet power cables contain an insulated green/yellow grounding wire that connects the frame to the ground terminal at the AC source power outlet. A similar insulated green or green/yellow wire ground, of at least the same diameter as the phase wire, is required between the branch circuit panel and the power receptacle that attaches to each cabinet.
Site Evaluation – Internal Considerations Figure 4-2. Transient Electrical Grounding Plate Power Panel Flat Braded/ Straned Wire Plate Concrete Floor A502_047 Electrostatic Discharge Electrostatic discharge (ESD; static electricity) is caused by movement of people, furniture, and equipment. ESD can damage circuit card components, alter information on magnetic media, and cause other equipment problems.
Site Readiness Planning Environmental Requirements and Hazards VSM5 system components are sensitive to corrosion, vibration, and electrical interference in enclosed environments such as data centers. Because of this sensitivity, equipment should not be located near areas where hazardous and/or corrosive materials are manufactured, used, or stored, or in areas with above-average electrical interference or vibration levels.

Site Evaluation – Internal Considerations Raised-Floor Pedestal Ratings Raised floor pedestals must be able to resist an axial load of 2268 kg (5000 lbs.). Where floor panels are cut to provide service access, additional pedestals may be required to maintain the loading capacity of the floor panel. Physical Space Requirements Floor space and layout requirements can differ for each VSM5 system configuration. Figure 4-4 shows dimensions and recommended service clearances for a VSM5-VTSS cabinet.

FICON Channel Extension Guidelines B This appendix provides information about FICON channel extensions for the VSM system.
FICON Channel Extension Guidelines ■ Definition of Terms The following terms are used in this appendix: • Front-end – any equipment between a host and a VTSS • Back-end – any equipment between a VTSS and RTD • Channel extension – a configuration of equipment that exceeds the maximum distance allowed by native FICON protocol, implemented by adding a pair of channel extenders.
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 operates 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.
FICON Channel Extension Guidelines ■ FICON Topologies See “Placement of Extension Equipment” below to determine proper placement of extension equipment for the following FICON topologies: 1. Host-to-VTSS (front-end link to VTDs) a. direct-attach connection b. single FICON director/switch connection c. cascaded directors/switches connection 2. VTSS-to-RTD (back-end link to RTDs) a. direct-attach connection b. single FICON director/switch connection c. cascaded directors/switches connection 3.

FICON Channel Extension Guidelines The FICON directors on the supported list provide a port configuration option for link speed. The VSM port runs in auto-speed mode (currently unconfigurable). The recommendation is to set all FICON director ports attached to extension equipment to a fixed speed, and to set the attached extension ports to a fixed speed, as follows: • Set the FICON director port to ‘1Gbps-ONLY’ for attachment to the USD-X channel extender.
Cisco Systems Channel Extension Interoperability ■ Cisco Systems Channel Extension Interoperability The following interoperability and configuration information and guidelines apply when using Cisco Systems channel extension equipment with a VSM-VTSS. Note: This qualification is for distances up to 200km without any performance penalty. Cisco is planning a performance improvement beyond the current 200km limit, which will be tested by Sun once that code level is delivered.

Glossary A AC. Alternating current. Current in which the direction is reversed, or alternated, 60 times per second (50 times per second in some countries). Contrast with direct current. acceptance test. A formal test done by a system enduser to determine if a system works according to specifications and should be accepted. access density. A measure of I/O activity; the number of I/O operations per gigabyte of functional capacity per second. access privileges.
asynchronous. Not synchronized; not occurring at regular, predetermined intervals. Asynchronous transmissions send one data character at a time, at irregular intervals, rather than in one steady stream; a start bit and a stop bit notify the receiver when the transmission begins and ends. Contrast with synchronous. ATA. Advanced Technology Attachment. Official name for the disk drive interface standard commonly known as Integrated Drive Electronics (IDE). ATM. Asynchronous transfer mode.
CD-ROM. Compact Disc Read-Only Memory. An optical disc that may contain computer data, audio data, graphics, and other information, and is interchangeable between different types of computers. Storage capacity is typically about 680 MB per disc. CDS. Control data set. An HSC database containing all configuration and volume information, used by host software to control functions of automated libraries. CEI. Configured end item. CFE. Composite Failure Event.
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. Conversions may require special tools and higher-level skills of a technical specialist. Contrast with upgrade. count-key data (CKD). A recording format that writes variable-length records. Contrast with fixed-block architecture. CPAT.
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 function, or because software for that function is not installed. Available options are typically displayed in undimmed black text. Dynamic Configuration.
environmental stress screening (ESS). A method of causing weak components in a machine to fail by applying environmental stresses much greater than normal product environmental specifications, including temperature extremes, temperature shock, and vibration. F EPE. Early/External Product Evaluation fabric. (1) In Fibre Channel (FC), a structure that allows addressing of ports on a FC network to be done independently of the physical location or address of a target port.
Fibre Channel (FC). An ANSI-standard serial interface used to provide high-speed data transfers between workstations, 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 Channel-Arbitrated Loop (FC-AL), point-to-point, and switched fabric. ume image as known to a VTSS. FICON. FIbre CONnection.
H technology with ISO. 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 software components that uses characters inserted into a data stream to indicate when to start or stop sending data. (2) A voltage or pulse signal exchanged between two hardware components to establish a valid connection between two computers. HBA. Host bus adapter.
J logical array. A grouping of devices into an array independent of physical device locations. jack. A connector into which a plug is inserted. logical block address (LBA). A four-byte number used to identify a logical block on a SCSI drive. The address range is 0 to n, where n equals the number of blocks on a drive. JBOD. Just a Bunch of Disks. A term used to describe a data storage cabinet that contains only disk storage devices, without an internal control unit.
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). Average time from the beginning of troubleshooting activities (when a CSE starts work on a unit) until a subsystem (or part of it) is returned to full functionality and total customer control.
P 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 errorchecking code. The data packets for a specific message may take different routes to a destination, and the packets are reassembled on arrival. PAD. Packet assembly/disassembly. See packet. PAL. Programmable Array Logic. parallel. Side by side.
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. Contrast with deinstallation. remote customer service engineer (RCSE).
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 relationship. Synchronous transmissions send strings of data characters at regular intervals without the need for start and stop bits required for asynchronous transmissions, making them faster than asynchronous transmissions.
VTCS. Virtual Tape Control System. In VSM, primary host software that controls activity and coordinates operations 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 arrays. VTCS software operates in the same address space as the HSC, and communicates closely with it. VTD. Virtual Tape Drive. A transport in a VTSS that emulates a physical 3490E tape drive to a MVS system.
