For more details about service processors, see 2.8, "Service processor" on page 65.
Ethernet ports
The PS703 has a 2-port onboard integrated Ethernet adapter for a total of two Ethernet ports.
The PS704 has two 2-port onboard integrated Ethernet adapters with one in the base blade
and the second one in the SMP blade for a total of four Ethernet ports.
Note: The PS703 and PS704 do not have the Host Ethernet Adapters (HEAs) and
Integrated Virtual Ethernet (IVE) ports that previous Power blade servers have included. A
virtual Ethernet can be provided from the Virtual I/O Server virtual network environment.
For more details about Ethernet ports, see 2.7.5, "Embedded Ethernet Controller" on
page 63.
SAS Controller
The PS703 blade server has one integrated SAS controller. The PS704 has one integrated
SAS controller located on the SMP blade.
The integrated SAS controller is used to drive the local SAS storage. This SAS controller can
also support SATA SSD with the addition of the SSD Interposer for 1.8-inch solid-state drives
as shown in Figure 1-11.

The integrated SAS controller supports hardware RAID 0, RAID 5, RAID 6, or RAID 10
depending on the number of drives installed.
The 3 Gb SAS Passthrough Expansion Card can be used to connect to the BladeCenter SAS
Connectivity Module, which can be connected to the external storage. This SAS pass-through
expansion card can also be used to connect to BladeCenter S internal drive SAS drives. See
"3 Gb SAS Passthrough Expansion Card (CIOv)" on page 23 for more information. See also
"SAS adapter" on page 61 and 2.9, "Internal storage" on page 68.
USB controller
The USB controller connects the USB bus to the midplane, which is then routed to the media
tray in the BladeCenter chassis to connect to USB devices (such as an optical drive or
diskette drive).
For more information, see 2.7.6, "Embedded USB controller" on page 64.
