A drive carrier includes a first computing device with light source control capacity and a light source proximate to a front plate of the drive carrier. The first computing device receives a signal from a second computing device (external to the drive carrier) and controls the light source proximate to the front plate of the drive carrier based on the signal.

Drive carrier light source control

In one aspect, the invention is a tuned stub, SCSI topology comprising a SCSI bus, a breakout node on the SCSI bus, an external SCSI connector on the SCSI bus at a first point defined by a first propagation delay; an internal SCSI connector on the SCSI bus at a second point defined by a second propagation delay, the first and second propagation delays being substantially equal; a SCSI adapter electrically tapping the breakout node; and a terminator electrically tapping the breakout node.

Method and apparatus implementing a tuned stub SCSI topology
