Question

Which SCSI standard allows for the technique known as “hot swapping”? Ultra SCSI Original SCSI Serial SCSI Fast-Wide SCSI

Answer 1

Serial SCSI, known as Serial Attached SCSI (SAS), allows for hot swapping, which enables replacing or adding components without system downtime.

Step-by-step explanation:

Among the SCSI standards mentioned, Serial SCSI, also known as Serial Attached SCSI (SAS), is the one that supports hot swapping. Hot swapping is a feature that allows for the replacement or addition of components without shutting down the system.

This is particularly useful in server environments where uninterrupted operation is critical. Neither the original SCSI nor Ultra SCSI inherently supports hot swapping, as these earlier standards require the device to be turned off before components can be changed. Fast-Wide SCSI, while an improvement on earlier standards in terms of speed and width, also does not specify hot swapping. Over time, hot swapping has become a desired feature due to the convenience and reduced downtime it offers.

Answer 2

Serial SCSI

Step-by-step explanation:

Hot swapping can be defined as a process which typically involves fitting or replacing CD-ROM drive, hard-disk drive, power supply or other peripheral devices while a computer system is powered on. Thus, it allows for the installation or removal of a peripheral device from a computer while power is still being supplied to the computer i.e without having to shutdown the computer.

Serial SCSI is a SCSI standard which allows for the technique known as “hot swapping” because it's a point to point connection that is designed to move data to and from computer storage serially.
