RS-232, 10/100 Ethernet, or through a customer unique
approach. JBOD disk array and RAID subsystem developers
are provided a common hardware and software platform,
which supports all subsystem diagnostic and enclosure
management strategies. The VSC205 may be used as the
master controller of an I
2
C serial interface communicating with
scalable slave backplane controllers such as the Vitesse
VSC055 and other industry standard I
2
C devices.

LVD SCSI Enclosure Management Controller
VSC205
The VSC205 is a SCSI enclosure management
controller for peripheral storage applications.
This device supports in- and out-of-band
management strategies. The VSC205
implements in-band SES and SAF-TE
enclosure management via the integrated
SCSI interface. Out-of-band solutions are possible using
IPMI (Intelligent Platform Management Interface),
