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.
- Additional build conventions for 2800 processing/storage cabinets:
- 2800 cabinets have a variety of configurations. The location and number of 4+0 and 2+0 cliques in a 2800 base or expansion cabinet depends, in part, on the type of power used for the 2800 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 B, C, or D power, in cabinet configurations with more than one 4+0 clique, the first 4+0 clique occupies U spaces 2-13, a second 4+0 clique can occupy U spaces 14-19 and 25-30 (with the BYNET V5 InfiniBand switches and cabling space, system VMS, and KVM chassis in U spaces 20-24), and a third 4+0 clique can occupy U spaces 31-42.
- 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 number of chassis supported in the base cabinet depends, in part, on the type of power used for the 2800 cabinet.
- A 2800 system can support one or more of the following in the base cabinet, depending on cabinet build and power type:
- A second 2800 system (4+0 clique or 2+0 clique). The second 2800 system must be field-installed and is part of a multi-system configuration.
- One or two 680 systems (each with one node and one disk array). 680 systems must be field-installed and are part of a multi-system configuration.
- Quantum i80 tape libraries used for backup and restore (BAR). The base 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) must be placed only in base cabinets. The base cabinet supports one DD4200 with up to four ES30 expansion shelves.Only one TMS BAR is permitted for the Data Domain DD4200 and ES30 options.This document gives basic chassis location guidelines. For detailed system design considerations, including guidelines for future system capacity upgrades, see the Ordering & Configuration Information document for Model DD4200.
