Before you go on, read:

• “What is a Partition?” on page 298.

• “What is a Cell?” on page 303:

- “Core Cell” on page 309

• “What is an XBC (Crossbar Controller)?” on page 312:

- “Crossbar Connections” on page 314.

Other terms and concepts:

• “Recommendations for Cabling Crossbar Controllers (XBCs)” on page

324.

• 16-, 32- 64-way-capable-system, CPU cabinet:

see “What is a CPU Cabinet?” on page 299.

Points to Note

• A partition is similar to a conventional single system. This means

that the partition as a whole has access to all the resources in it:

processors, memory and I/O are all shared among all the cells in the

partition.

•A16-way-capable system should have at least two cells, a

32-way-capable system should have at least four cells, and a

64-way-capable system should have at least eight cells.
