System Features

Bus Architecture
Depending on your system configuration, four or six PCI-X slotted riser cards are available. The slots are
64-bit capable at 133 MHz, 3.3 volts. If your system has four PCI-X slots, use slots 3 and 4 with PCI
adapters that require high performance. Use slots 1 and 2 with PCI adapters that do not require high
performance. On the six-slotted PCI riser cards, all slots are equal. All slots are capable of using the
full-length PCI-X adapters. The PCI-X slots are numbered on the rear of the chassis, from left to right.
When equipped with POWER4+ processors and a six-slotted PCI riser card, the Model 6C4 and Model
6E4 include six hot-plug PCI-X slots, dual integrated Ultra3 SCSI controllers, dual 10/100 Mbps integrated
Ethernet controllers, and four front-accessible disk bays supporting hot-swappable disks. These disk bays
can accommodate up to 587.2 GB of disk storage using 146.8 GB Ultra3 SCSI disk drives. Two media
bays are used for a CD-ROM, DVD-RAM, DVD-ROM, or another optional media device, such as a tape or
diskette drive. The Converged Service Processor (CSP), including system power control, is also
integrated, along with the native I/O functions such as serial ports, keyboard, and mouse. Also included
are an enhanced I/O subsystem with the implementation of the remote I/O (RIO) interconnect and PCI-X
bus protocols.
The Model 6C4 can support up to two high-density 7311 Model D20 I/O drawers to provide additional
PCI-X slots and disk drive bays. A fully configured system with two I/O drawers has 20 PCI-X slots and 4.1
TB of disk space. Optionally redundant hot-plug cooling fans and power supplies are available.
All PCI-X slots can run 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.
