General Conventions

The placement of the hardware components in a cabinet follows these general cabinet build conventions:
  • All chassis except the top Ethernet switches are loaded from the front of the cabinet, and accessible from both front and rear of the cabinet. The top Ethernet switches are loaded and accessible only from the rear of the cabinet.
  • Each chassis has a standard position in the cabinet, and is numbered from the bottom up.
  • Chassis can be managed, monitored, or unmanaged.
    • Managed chassis are connected to the primary server management network by an Ethernet port on the chassis. Chassis with a second Ethernet port are connected to the secondary server management network. Managed chassis are actively monitored by server management and allow service personnel to manage various chassis functions through SMWeb Services.
    • Monitored chassis are connected to server management through a customer network and are subject to customer network configuration and availability. Monitored chassis are actively monitored by server management but service personnel cannot manage chassis functions through SMWeb Services.
    • Unmanaged chassis are not connected to the primary or secondary server management networks. The chassis are not monitored by server management and service personnel cannot manage chassis functions through SMWeb Services.
  • Chassis that are managed or monitored over the server management network have assigned chassis ID numbers. The chassis ID number identifies the chassis by position/type in the server management interface.
  • Unmanaged chassis can be numbered by position for cabling purposes only. If numbered, the numbers do not appear in the server management interface as identification of the chassis.

2850 System Conventions

Additional build conventions for 2850 cabinets:
  • 2850 cabinets have a variety of configurations. The location and number of cliques in a 2850 cabinet depends, in part, on the type of power used for the cabinet. Cabinet builds in the following sections are divided into type A power and type B, C, or D power. For definitions of these power types, see the Platform Features Summary in the Product and Site Preparation Guide.
  • For type A power, note that there are U space positions where no chassis are allowed. These spaces must remain empty.
  • For type B, C, or D power, clique components (nodes and disk arrays) can be installed in a variety of positions, depending on the configuration, but only the installation locations shown in the cabinet drawings are allowed.
  • The 36-port BYNET V5 InfiniBand switches and cabling space, system or cabinet VMS, and KVM chassis (if installed) are generally installed in spaces 20-24. Larger BYNET switches are installed in a dedicated BYNET cabinet, a Platform Framework Cabinet, or another platform cabinet.
  • Aster 5 nodes, Hadoop 5 nodes, and Hadoop 6 nodes may be placed in available slots in Cabinet 1, subject to space and power restrictions.
  • Channel servers, Network Connectivity Servers (NCSs), SAS HPA worker nodes, TMSs, and TMSSs may be placed in Cabinet 1 or the Platform Framework Cabinets.
A 2850 system can also support one or more of the following in Cabinet 1 (base cabinet):
  • A second or third 2800 or 2850 system (either a 4-node or 2-node single-clique system) in addition to the primary system.
  • One or two 680 systems (with one processing node and one disk array each).
  • A combination of one additional 2800 or 2850 system (either a 4-node or 2-node single-clique system) and one or two 680 systems.
  • Quantum i80 tape libraries used for backup and restore (BAR). The first cabinet supports up to two tape libraries with an optional pair of key management servers.
    Only one TMS BAR is permitted for these i80 BAR tape library configuration options.
  • The Data Domain DD4200 and ES30 expansion shelves used for backup and restore (BAR). The first cabinet supports one DD4200 with up to four ES30 expansion shelves.
    This document gives basic chassis location guidelines for the BAR components. For detailed system design considerations, including guidelines for future system capacity upgrades, see the Ordering & Configuration Information document for Model DD4200.
    Only one TMS BAR is permitted for the Data Domain DD4200 and ES30 options.

Cabinet builds shown in the following sections are based on chassis configurations that use the maximum power. In some cases, additional chassis may be allowed in the cabinet, if the configuration is approved by Teradata. Customers should contact their Teradata Representative who in turn will submit a request to Global Sales Support for review of the proposed exception to the build restriction.
