The placement of the hardware components in a cabinet follows these general cabinet build conventions:
  • Each chassis has a standard position in the cabinet, and is numbered from the bottom up.
    • Chassis that are managed over the server management network have assigned chassis ID numbers. The chassis ID number identifies the chassis by position/type in the management interface.
    • Unmanaged chassis are numbered by position for cabling purposes only. The numbers do not appear in the management interface as identification of the chassis.
  • 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.
  • Additional build conventions for 2750 processing/storage cabinets:
    • In a base cabinet with a 4-node clique, all four nodes in the clique are not adjacent to each other - the top node of the clique (chassis 15) is separated from the bottom three nodes (chassis 8, 9, 10) by the BYNET switches, VMS, and KVM chassis.
    • Channel servers, Extended Channel Solution (ECS) servers, Network Connectivity Servers (NCSs), SAS HPA worker nodes, Teradata Managed Servers (TMSs), and Teradata Managed Storage Servers (TMSSs) must be placed in base cabinets or Platform Framework Cabinets. The base cabinet supports up to eight of these chassis.
    • The Quantum i80 tape libraries used for backup and restore (BAR) must be placed only in base cabinets. The base cabinet supports one tape library with an optional pair of key management servers, or up to two tape libraries without key management.
      Only one TMS BAR is permitted for these Scalar i80 BAR tape library configuration options.
    • The Data Domain 4200 and ES30 expansion shelves used for backup and restore (BAR) must be placed only in base cabinets. The base cabinet supports one DD4200 with up to three ES30 expansion shelves.
      Only one TMS BAR is permitted for the Data Domain 4200 and ES30 options.
      This document gives basic chassis location guidelines. For detailed system design considerations, including guidelines for future system capacity upgrades and multiple Data Domain systems, see the Ordering & Configuration Information document for Model DD4200.
    • Test/development systems must be placed only in base cabinets. Each Teradata production system, consisting of one or more production cabinets, supports up to two test/development systems.
