Chapter 1. Introducing the System

This chapter provides information about the system features of the pSeries 630 Model 6C4 and Model 6E4. The Model 6C4 is a rack mount system and the Model 6E4 is a deskside system.

System Features

Bus Architecture

Four PCI slots are available. Slots numbered 3 and 4 are 64-bit capable at 133 MHz,

3.3volts. Use these slots with PCI adapters that demand high performance. Slots numbered 1 and 2 are 64-bit capable at 66 MHz, 3.3 volts. Use these slots with PCI adapters that do not demand high performance. All slots are capable of running either 64-bit or 32-bit adapters. However, a 32-bit adapter operates in a 32-bit mode and shows no performance advantage while running in a 64-bit slot. The following illustration shows the PCI Adapter Slot locations when viewing from the rear of the system.

Processors

vOne and two-way cards with POWER4 1.0 GHz microprocessors.

Note: Only a single 1-way card is allowed per server at one time; therefore, a 3-way configuration is unavailable.

vAn upgrade from a 1-way (FC 5131) to a 2-way (FC 5132) is available by feature conversion.

v32 MB L3 cache per-processor card
