term: System Bus
A system bus connects peripherals to the CPUs. The Teradata Database supports two kinds of system buses:
- PCI (Peripheral Component Interconnect)
- MCA (Micro Channel Architecture)
Slots on the system bus are used for the following types of connections:
- LAN connections
- Mainframe channel connections
- Connections to the external disk array cabinets
Depending on the platform (such as Teradata 4800, Teradata 5100, etc.), the system bus can also be used to connect the CPUs to:
- Local peripheral board (LPB)
- Internal RAID disk arrays
