Table 6 provides information on the connector types for PCI-X I/O Modules.
PCIe I/O Module
To provide more flexibility and to support newer PCI cards, a PCIe I/O module is available. The PCIe I/O
Module supports eight PCIe cards in total, and one I/O module can have one PCIe card assigned per
server blade. The PCIe I/O Module uses a PCIe hot plug controller manufactured by MICREL. Hot plug
is supported for each PCIe slot in the PCIe I/O Module. The operating system must support hog plug in
order for this operation to be successful.
PCIe I/O Module Combo Card
A PCIe I/O Module Combo Card is available for the BladeSymphony 1000, which can be installed in the
PCIe I/O Module and provides additional FC and gigabit Ethernet configurations. The block diagram is
shown in Figure 17. The card includes two1/2/4 Gb/sec. FC ports supporting FC-AL and point-to-point
switch fabric. Two gigabit Ethernet ports are also included. These ports support auto-negotiation and
VLAN (compatible to IEEE 8.2.1Q and a maximum of 4096 TagVLANs).

Embedded Fibre Channel Switch Module
The Embedded Fibre Channel Switch Module consists of a motherboard, with one daughter card with
an FC switch installed, and eight FC-HBA + Gigabit Ethernet Combo Cards. It enables the use of both
FC and LAN functions from each server blade in the BladeSymphony 1000 chassis. Figure 18 shows
an outside view of this module.
