WorldMark 4800- 48xx System Configurations / 1 to 4 Nodes

The WorldMark 4800 and 4850 series systems have one to four SMP nodes.

The 48xx system is anchored by a base cabinet (also referred to as the system cabinet). The base cabinet houses a BYNET switch board (BYA4P or BYA4G depending on model) in each of two SMP Teradata nodes. The BYA switch board can interconnect as many as four nodes. The dual switches provide for a redundant BYNET network. A BYNET adapter (BIC2G or BIC2C, depending on model) is contained in every node in the system. The multi-ported adapter provides for node connection to both BYNET switches.

The expansion cabinet is the add-on rack, with two SMP Teradata nodes connecting to the BYNET switches in the base rack. The expansion cabinet also contains a PvtLAN hub, which is used to connect all four node chassis in the system to the system console for TCP/IP login capability.

A single node cabinet is an option for a one or three-node 4800 or 4850 system configuration. The 48xx single node cabinet contains one SMP node and no PvtLAN hub.

All cabinet variations are configured with 3 UPS/UIS chassis at the bottom of the rack and a service subsystem chassis at the top.

All 48xx system configurations include an AWS with two network hubs, one for the PvtLAN and one for the SLAN. The PvtLAN hub funnels multiple node Ethernet connections into a single connection at the console. The SLAN hub converts a 10Base2 coaxial connection from the rack cabinets to a 10BaseT twisted pair Ethernet connection at the console.

Note: Earlier AWS models use an internal coaxial adapter for the SLAN connection, instead of the external SLAN hub.

Coexistence Systems for WorldMark 4800

The following WorldMark platforms (UNIX-based only) can coexist as a single MPP platform:

• 4800 and 4700/5150
• 4800 and 4850
• 4850 and 4700/5150
• 5200 and 5250

In a coexistence system, all processing nodes in each platform are connected as one system through the same BYNET infrastructure (either version 1 or version 2 as applicable to the platforms involved). All of the nodes can be administered through the single operational view of the AWS.

Processing Node Subsystem- WorldMark 4800

Two symmetrical multi-processing (SMP) node chassis are resident in a typical processing rack configuration. They are always referenced as chassis IDs #4 and #5, top and bottom respectively.

Note: In the single node rack configuration of the 48xx system model, only the bottom node, chassis #5, is present.

The SMP node is the processor building block of the system, with each node containing a minimum configuration that includes:

• 4 Pentium III CPUs, 1 MB cache (XEON modules)
• 1 GB of EDO RAM
• 1 BYNET interface adapter (BIC2G, BIC2C, or BIC4G, depending on model)
• 1 dual 10/100 Ethernet adapter (PvtLAN)
• 1 single-ended SCSI adapter (internal drives only)
• 49 GB 10,000 RPM disk drives
• 18 mm tape drive
• 13.5-inch flex drive
• 1 CD ROM drive

Additional PCI-based options are available, as required per system site, including the NCR PCI Quad SCSI (PQS) adapter or high performance PQS (HP-PQS) adapter for mass external storage interface, and Teradata IBM channel adapter for mainframe interface.

NCR WorldMark 48xx Node Components

WorldMark 48xx Hardware

Following is a summary of the hardware components that comprise the SMP node subsystem:

• A450NX system board set: Dual baseboard design that includes:
  • CPU baseboard
  • I/O baseboard
  • Interconnect backplane

The baseboards are physically placed back to back, connected to each other by the interconnect backplane. Two expander buses (F16 buses) electrically connect the two baseboards together. Power to the board set is supplied through the interconnect backplane.

• CPU baseboard: Faces the left side of the chassis, and supports the following features:
  • Processors: Four Xeon processor modules, each containing the processor core and L2 cache components inside a single edge connect (S.E.C.) cartridge. The cartridges plug into the CPU baseboard, and interconnect through the front side bus (FSB) to form 4-way SMP architecture.
    
    
  • Memory: Two high capacity DRAM memory boards. The 4800/5200 node supports up to 4 GB of memory, using 16 dual in-line memory modules (DIMMs).
  
  
  
• I/O baseboard: Faces the right side of the chassis, and provides the following connections:
  • 11 PCI bus master slots (one shared with ISA) fast/wide SCSI II connection for flex drive
  • ultra/wide SCSI connection for 5.25-inch tape drive and CD-ROM
  • two IDE connectors
  • I/O panel including serial, parallel, and USB ports
  
  
  
• ICMB (Intelligent Chassis Management Bus): Provides interface between the server management components within the node (i.e., Intel I2C microcontrollers) and the service subsystem in the rack. This interface of node to service subsystem accomplishes the overall chassis management strategy of the larger system.
  
  
• Power: Three AC power inputs to three hot-plug 625-watt AC-DC power supplies. Each power supply connects to power adapter board, then to power translator board, then to power distribution backplane. The distribution backplane interfaces with the interconnect backplane to provide power to the CPU and I/O baseboards. It also distributes power to the SCSI backplane and fans.
  
  
• Fans: Eight fans in three separate assemblies. CPU side of the chassis is cooled by a pair of dual fan arrays, at front and rear. I/O side of the chassis is cooled by a four-fan array at the front.
  
  
• SCSI Drives/Backplane: Hot-swap drive backplane supports 5 available hot-swappable internal disk drives, 9 GB or 18 GB 10000 RPM.

WorldMark Storage is part of a highly orchestrated system designed to maximize Teradata database operation and execute superior performance under the rigorous demands of active data warehousing.
