Figure 2-10 Conceptual diagram of the 7311-D10 I/O drawer

7311 Model D10 features

This I/O drawer model provides the following features:

￿Six adapters slots:

Five hot-plug 64-bit 133 MHz 3.3 V PCI-X slots, full length, blind-swap cassette

One hot-plug 64-bit 33 MHz 5 V PCI slot, full length, blind-swap cassette

￿Default redundant hot-plug power and cooling

￿Two default Remote I/O ports and two SPCN ports

7311 Model D11 features

This I/O drawer model provides the following features:

￿Six hot-plug 64-bit, 133 MHz, 3.3 V PCI-X slots, full length, enhanced blind-swap cassette

￿Default redundant hot-plug power and cooling

￿Two default remote (RIO-2) ports and two SPCN ports

Note: The 7311-D10 must have the RIO- 2 loop adapter (FC 6438) to be supported by a p5-570 system.

2.7.3 7311 Model D20 I/O drawer

The 7311 Model D20 I/O drawer must have the RIO-2 loop adapter (FC 6417) to be connected to the p5-570 system. The PCI-X host bridge inside the I/O drawer provides two primary 64-bit PCI-X buses running at 133 MHz. Therefore, a maximum bandwidth of 1 GBps is provided by each of the buses. To avoid overloading an I/O drawer, follow the recommendation in the IBM Sserver Hardware Information Center at:
