Technical Product Specification

Hard Disk Drive Support Intel® Server System SR1600UR TPS
36 Intel order number E45725-010 Revision 1.8
6.3.1.1 Vitesse VSC410 Enclosure Management Controller
Both the active and passive backplanes support enclosure management using a Vitesse
VSC410 management controller.
The VSC410 drives the hard drive activity/fault LED, hard
drive present signal, and controls hard drive power-up during system power-on.
In addition, the
VSC410 supports the IPMI specification by providing management data to the Integrated
Baseboard Management Controller on the server board.
6.3.1.2 LSISAS1064E 3.0 Gb/s Serial Attached SCSI Controller
The LSISAS1064E serial attached SCSI (SAS) controller is integrated on to the active SAS
backplane.
The LSISAS1064E is a four-port, 3.0 Gb/s SAS/SATA controller that is compliant
with the Fusion-MPT* architecture. It provides an eight-lane PCI Express* interface and
supports Intel
®
Embedded RAID Technology II. The point-to-point interconnect feature of the
PCI Express* bus limits the electrical load on links, allowing increased transmission and
reception frequencies. PCI Express* transmission and reception data rates for each full-duplex
interconnect is 2.5 Gb/s.
Figure 23. LSISAS1064E SAS Controller Functional Diagram
PCI Express* implements a switch-based technology to interconnect a large number of devices.
Communication over the serial interconnect is accomplished using a packet-based
communication protocol. Quality of Service (QOS) features provide differentiated transmission
performance for different applications. Hot-plug/hot-swap support enables “always-on” systems.
Enhanced error handling features, such as end-to-end CRC (ECRC) and Advanced Error
Reporting, make PCI Express* suitable for robust, high-end server applications. Hot-plug,
power management, error handling, and interrupt signaling are accomplished using packet
based messaging rather than sideband signals.
