Intel® Server Board S2600GZ/GL TPS Product Architecture Overview
3.3.1
Low Pin Count (LPC) Interface
The chipset implements an LPC Interface as described in the LPC 1.1Specification and provides support for up
to two Master/DMI devices. On the server board, the LPC interface is utilized as an interconnect between the
chipset and the Integrated Base Board Management Controller as well as providing support for the optional
Trusted Platform Module (TPM).
3.3.2
Universal Serial Bus (USB) Controller
The chipset has two Enhanced Host Controller Interface (EHCI) host controllers that support USB high-speed
signaling. High-speed USB 2.0 allows data transfers up to 480 Mb/s which is 40 times faster than full-speed
USB. The server board utilizes nine USB 2.0 ports from the chipset. All ports are high-speed, full- speed, and
low-speed capable.
Three external USB ports are provided in a stacked housing located on the rear I/O section of the
server board.
Two USB ports are routed to an internal 10-pin connector (Labeled “FP_USB” on the server board) that
can be cabled for front panel support.
One internal Type ‘A’ USB port.
One eUSB connector intended for use with an optional eUSB SSD device.
Two USB ports are routed to the integrated BMC.
3.3.2.1
eUSB SSD Support
The server board provides support for a low profile eUSB SSD storage device. A 2mm 2x5-pin connector
labeled “eUSB SSD” near the rear I/O section of the server board is used to plug this small flash storage
device into.
Figure 27. Low Profile eUSB SSD Support
eUSB SSD features include:
2 wire small form factor Universal Serial Bus 2.0 (Hi-Speed USB) interface to host
Read Speed up to 35 MB/s and write Speed up to 24 MB/s.
Capacity range from 256 MB to 32 GB.
Support USB Mass Storage Class requirements for Boot capability.
3.3.3
Embedded Serial ATA (SATA)/Serial Attached SCSI (SAS)/RAID Support
The Intel
®
C602 chipset provides storage support from two integrated controllers: AHCI and SCU. By default
the server board will support up to 6 SATA ports: Two single 6Gb/sec SATA ports routed from the AHCI
controller to the two white SATA connectors labeled “SATA-0” and “SATA-1”, and four 3Gb/sec SATA ports
routed from the SCU to the mini-SAS connector labeled “SCU_0 (0-3)”.
Note: The mini-SAS connector labeled “SCU_1 (4-7)” is NOT functional by default and is only enabled with the
addition of an Intel
®
RAID C600 Upgrade Key option supporting 8 SAS/SATA ports.
