3.4 SAS Controller
The SAS1064e controller supports x4 PCI Express* link widths and is a single-function PCI
Express end-point device. The SAS controller supports the SAS protocol as described in the
Serial Attached SCSI Standard, version 1.0. The controller also supports SAS 1.1 features.
The SAS1064e controller supports a 32-bit external memory bus that provides an interface for
Flash ROM and NVSRAM devices.
3.4.1 SAS RAID Support
RAID modes 0, 1, and 10 are supported. An optional SAS RAID Key can be used to support SW
RAID 5.
3.4.2 SAS / SATA Connector Sharing
Four SATA connectors are shared between SATA and SAS, depending on the version of the
server board. For SAS server boards, four of the six SATA connectors are used for SAS
functionality. For SATA server boards, all six SATA connectors are used for SATA functionality.
3.5 Network Interface Controller (NIC)
Network interface support is provided from the built in Dual GbE MAC features of the ESB2 in
conjunction with the Intel
®
82563EB compact Physical Layer Transceiver (PHY). Together, they
provide the server board with support for dual LAN ports designed for 10/100/1000 Mbps
operation.
The 82563EB device is based upon proven PHY technology integrated into Intel’s gigabit
Ethernet controllers. The physical layer circuitry provides a standard IEEE 802.3 Ethernet
interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and
802.3ab). The 82563EB device is capable of transmitting and receiving data at rates of
1000 Mbps, 100 Mbps, or 10 Mbps.
Each network interface controller (NIC) drives two LEDs located on each network interface
connector. The link / activity LED (at the right of the connector) indicates network connection
when on, and transmit / receive activity when blinking. The speed LED (at the left of the
connector) indicates 1000-Mbps operation when amber, 100-Mbps operation when green, and
10-Mbps when off. The table below provides an overview of the LEDs.
