2.5.1 PCI-X slots and adapter
PCI-X, where the X stands for extended, is an enhanced PCI bus, delivering a theoretical
peak bandwidth of up to 1 GB/sec, running a 64-bit bus at 133 MHz. PCI-X is backward
compatible, so the OpenPower 710 servers can support existing 3.3 volt PCI adapters.
Restriction: The integrated PCI-X card slots do not support hot-plug.
2.5.2 LAN adapters
When an OpenPower 710 server is connected to a local area network (LAN), the internal dual
port 10/100/1000 Mbps RJ-45 Ethernet controller integrated on the system planar can be
used. Except for the VPD module, the integrated dual 10/100/1000 Mbps Ethernet subsystem
is identical to the FC 5706 IBM 2-Port 10/100/1000 Base-TX Ethernet PCI-X Adapter.
Table 2-2 provides a list of additional LAN adapters available at the time of writing. IBM
supports an installation with Network Installation Manager (NIM) using Ethernet adapters

Enterprise Linux AS for POWER Version 4 or later.
2.5.3 SCSI adapters
The OpenPower 710 server has one internal dual port Ultra320 capable SCSI adapter
integrated on the system planar. Unlike the other IBM Sserver p5 or OpenPower models,
the OpenPower 710 server uses only one of the available SCSI busses for internal
connection to the four disk drives. The second SCSI bus has an external VHDCI LVD
connector on the rear of the system.
Note: It is not possible to add hardware RAID capabilities to the onboard adapter.
Table 2-3 shows a list of additional SCSI adapters available at the time of writing. All listed
adapters can be used as boot adapters.
