Glossary
• 16-, 32-, 64-way-capable system:
The three Superdome models currently available; see “What is a CPU
Cabinet?” on page 299.
• CPU cabinet:
Superdome’s hardware “box”; see “What is a CPU Cabinet?” on page
299.
• Cell; cell board:
Superdome’s hardware building blocks, containing memory,
processors and other core components; see “What is a Cell?” on page
303.
❏ active cell:
a cell in use in a partition; see “Active Cell” on page 309.
❏ base cell:
a cell assigned to a partition; see “Base Cell” on page 309.
❏ core (root) cell:
the cell that supports the console for its partition, and performs
other key functions; see “Core Cell” on page 309.
❏ inactive cell: a cell assigned to a partition which is not available
to the operating system running on that partition; see “Active
Cell” on page 309.
❏ unassigned (free) cell: a cell that has not been assigned to any
partition.
❏ viable core cell: a base cell that is attached to an I/O chassis
that contains a core I/O card. See “Core Cell” on page 309.
• Cell Controller (CC):
The chip on each cell that is responsible for maintaining data
coherency across all the cells in a partition, connecting the cell to I/O
(via the System Bus Adapter) and to the crossbar controller
(XBC). See “Cell Components” on page 304.
• Cell I/O:
Refers to the connection between cells and I/O chassis, which
contain I/O cards; see “Cell I/O” on page 308.
