Overview of PCI Adapters 1-3
System Configurations and PCI Slot Availability
Express5800/320Ma systems contain two CPU- I
⁄
O enclosures, each of which
contains a CPU element and an I/O element. The duplication of enclosures provides
redundancy in components such as processors, hard drives, PCI slots, and certain I/O
ports. PCI slots are logically associated with the I/O elements.
Express5800/320Ma 3.2 GHz systems contain one low-profile PCI slot in each
enclosure, for a total of two PCI slots in the system. Optionally, you can install an
AK533 attachment kit to add two full-height PCI slots to each enclosure
Express5800/320Ma 3.2 GHz, for a total of six PCI slots in the system.
Express5800/320Ma 3.6 GHz and Dual-Core systems contain one low-profile PCI slot
and two full-height PCI slots in each enclosure, for a total of six PCI slots in the system.
The CPU- I
⁄
O enclosures are removable and hot-pluggable. When you remove one
CPU- I
⁄
O enclosure to install a PCI adapter, the other enclosure in the system
continues to operate, providing uninterrupted use of the system.
You can use ftServer System Management Console (ftSMC) to view and manage the
components, including PCI adapters, in each I/O element. However, note that all I/O
elements display as I/O enclosure - n in ftSMC. Similarly, this manual and other
ftServer manuals may use the term enclosure in place of the term element.
For more information about working with elements and enclosures, see the operation
and maintenance guide for your system, as listed in
Table 1-2 . For more information
about ftSMC, see the Express5800/320Ma: System Administrator’s Guide and the
online Help.
PCI Slot Numbering, Reservations, and Performance
Each CPU- I
⁄
O enclosure in Express5800/320Ma 3.6 GHz and Dual-Core systems
contains one low-profile PCI slot that is physically labeled 1 and two additional
full-height PCI slots that are physically labeled 2 and 3 (see
Figure 1-1 ). ftSMC displays
these slots as PCI Slot Info - 9, 10, and 11.
Similarly, each CPU- I
⁄
O enclosure in Express5800/320Ma 3.2 GHz systems contains
one low-profile PCI slot that is physically labeled 1. ftSMC displays this slot as PCI Slot
Info - 9. In Express5800/320Ma 3.2 GHz systems, you can optionally install an AK533
attachment kit to add two full-height slots, providing the same configuration as
Express5800/320Ma 3.6 GHz and Dual-Core systems.
Each slot in a
Express5800/320Ma
3.2 GHz or 3.6 GHz system runs at a maximum of
100 megahertz (MHz). Slots 2 and 3, if present, are on one dedicated PCIX 100-MHz
bus, with no other traffic. Slot 1 is on a 100-MHz bus, but shares this bus with the
embedded Ethernet adapters and with a PCI bridge that carries the VGA, USB, SATA
disk, CD-ROM, and VTM traffic.
