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 baseboard
management controller on the server board.
6.3.1.2 LSI* SAS1064E 3.0 Gbit/s Serial Attached SCSI Controller
Integrated on to the active SAS backplane is an LSI* SAS1064E Serial Attached SCSI (SAS)
controller. The LSISAS1064E is a four-port, 3.0 Gbit/s SAS/SATA controller that is compliant
with the Fusion-MPT* architecture, 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 Gbit/s.

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.
Each of the four SAS phys on the LSISAS1064E is capable of SAS/SATA link rates of 3.0 Gbit/s
and 1.5 Gbit/s. The user can configure ports as wide or narrow. Narrow ports have one phy per
port. Wide ports have two, three, or four phys per port. Each port supports the SSP, SMP, STP,
and SATA protocols.
