Chapter 1. Introduction and general description 27For more details about service processors, see 2.8, “Service processor” on page 65.Ethernet portsThe 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 bladeand the second one in the SMP blade for a total of four Ethernet ports.For more details about Ethernet ports, see 2.7.5, “Embedded Ethernet Controller” onpage 63.SAS ControllerThe PS703 blade server has one integrated SAS controller. The PS704 has one integratedSAS controller located on the SMP blade.The integrated SAS controller is used to drive the local SAS storage. This SAS controller canalso support SATA SSD with the addition of the SSD Interposer for 1.8-inch solid-state drivesas shown in Figure 1-11.Figure 1-11 Interposer for 1.8-inch Solid State DrivesThe integrated SAS controller supports hardware RAID 0, RAID 5, RAID 6, or RAID 10depending on the number of drives installed.The 3 Gb SAS Passthrough Expansion Card can be used to connect to the BladeCenter SASConnectivity Module, which can be connected to the external storage. This SAS pass-throughexpansion 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 controllerThe USB controller connects the USB bus to the midplane, which is then routed to the mediatray in the BladeCenter chassis to connect to USB devices (such as an optical drive ordiskette drive).For more information, see 2.7.6, “Embedded USB controller” on page 64.Note: The PS703 and PS704 do not have the Host Ethernet Adapters (HEAs) andIntegrated Virtual Ethernet (IVE) ports that previous Power blade servers have included. Avirtual Ethernet can be provided from the Virtual I/O Server virtual network environment.SSDInterposerConnectorson the SSDInterposer forthe two SSDsSolid-statedrive
