6.1.1 Server Board and Storage Management Controller VSC410*
The Vitesse baseboard and storage management controller VSC410* for the SAS/SATA
backplane monitors various aspects of the storage enclosure. The chip provides out-of-band
SAF-TE, SES management through the SAS/SATA Host I
2
C interface, and HDD fault LED
status management through the SGPIO interface. The VSC410* also supports the IPMI
specification by providing management data to a server board management controller through
the IPMB.
The VSC410* controller has many general purpose input and output pins (GPIOs) that allow
customization. Some of these GPIOs are used for hard disk drive detection and driving hard
disk drive FAULT LEDs.
The VSC410* controller comes in a 64-pin Low Profile Quad Flat Pack (LQFP) package,
operates from 3.3 V and has an input clock frequency of 4 MHz.
