What is the purpose of SCSI? Compare and contrast SCSI with that of IDE? Which of the two is better for a Server? Justify your answer

Ans

It connects eternal device, connects power supply to analyze data.

-Small computer system interface.

-for peripheral devices connectivity (8 devices (0-7))

-Internal and external buses like power supply and extensive peripherals.

-Ultra SCSI - 32 devices (no wire is required, all with is uses is wireless).

-Physical drive accession - (Single hard dish is physical drive).

-Logical drive accession.

-SCSI ID is available in the device.

Topic	ATA/IDE	SCSI
Cost	Overall, IDE is a much cheaper solution.	When compared with IDE, SCSI is often more expensive to implement and support.
Expansion	IDE/EIDE allows 2 two devices per channel. Most computers have 2 channels.	SCSI is capable of supporting up to 7 or 15 devices.
Ease	IDE is commonly a much easier product to setup than SCSI.	Configuring SCSI can be more difficult for most users when compared to IDE.
Faster	Today, the latest IDE and SCSI drives running at the same RPM are very close. However, 10,000+ RPM drives are often only available for SCSI.	All the fastest drives are almost always available for SCSI first and in many cases 10,000+ RPM hard drives are only available as SCSI drives.
Resources	All motherboards today have an ATA/IDE interface and unless additional drives are needed no additional resources need to be taken.	Unlike IDE, SCSI requires an interface expansion card in most cases (unless the motherboard already has it). This means additional system resources will be required.
