8 IBM Power 570 Technical Overview and Introduction
FC 5757 IBM 4.7 GB IDE Slimline DVD-RAM Drive
1.3.4 I/O drawers
The system has seven I/O expansion slots per enclosure, including one dedicated GX+ slot.
The other 6 slots support PCI adapters. There are 3 PCIe 8X long slots and 1 PCIe 8X short
slot. The short PCIe slot may also be used for a second GX+ adapter. The remaining 2 slots
PCI-X long slots. If more PCI slots are needed, such as to extend the number of LPARs, up to
20 I/O drawers on a RIO-2 interface (7311-D11 or 7311-D20) ,and up to 32 I/O drawers on a
12X Channel interface (7314-G30) can be attached.
The adapters that are used in the GX expansion slots are concurrently maintainable on
systems with firmware level FM320_xxx_xxx, or later. If the GX adapter were to fail, the card
could be replaced with a working card without powering down the system.
7311 Model D11 I/O drawer
The 7311 Model D11 I/O drawer features six long PCI-X slots. Blind-swap cassettes are (FC
7862) are utilized. Two 7311 Model D11 I/O drawers fit side-by-side in the 4U enclosure (FC
7311) mounted in a 19-inch rack, such as the IBM 7014-T00 or 7014-T42.
The 7311 Model D11 I/O drawer offers a modular growth path for systems with increasing I/O
requirements. A fully configured system supports 20 attached 7311 Model D11 I/O drawers.
The combined system supports up to 128 PCI-X adapters and 16 PCIe adapters. In a full
configuration, Remote I/O expansion cards (FC 1800 - GX Dual Port RIO-2) are required.
The I/O drawer has the following attributes:
4U rack-mount enclosure (FC 7311) that can hold one or two D11 drawers
Six PCI-X slots: 3.3 V, keyed, 133 MHz blind-swap hot-plug
Default redundant hot-plug power and cooling devices
Two RIO-2 and two SPCN ports
7311 Model D11 I/O drawer physical package
Because the 7311 Model D11 I/O drawer must be mounted into the rack enclosure (FC 7311),
these are the physical characteristics of one I/O drawer or two I/O drawers side-by-side:
One 7311 Model D11 I/O drawer
– Width: 223 mm (8.8 in.)
– Depth: 711 mm (28.0 in.)
– Height: 175 mm (6.9 in.)
– Weight: 19.6 kg (43 lb.)
Two I/O drawers in a 7311 rack-mounted enclosure have the following characteristics:
– Width: 445 mm (17.5 in.)
– Depth: 711 mm (28.0 in.)
– Height: 175 mm (6.9 in.)
– Weight: 39.1 kg (86 lb.)
7311 Model D20 I/O drawer
The 7311 Model D20 I/O drawer is a 4U full-size drawer, which must be mounted in a rack. It
features seven hot-pluggable PCI-X slots and, optionally up to 12 hot-swappable disks
arranged in two 6-packs. Redundant concurrently maintainable power and cooling is an
