To improve server system performance, which of the following statements applies? Choose all correct options?

A.
Use SCSI controller cards that support asynchronous I/O.

B.
Upgrade from IDE and SCSI to UltraDMA or Wide Ultra SCSI.

C.
Upgrade from UltraDMA to IDE.

D.
Install separate drives on individual controller cards.

Explanation:
When you opt to use SCSI controller cards that support asynchronous I/O, you enable multiple drives to operate in parallel. This improves the performance of stripe sets.
Upgrading from IDE and SCSI to the faster UltraDMA or Wide Ultra SCSI technologies is recommended as well. Installing separate drives on individual controller cards has the advantage of spreading read and write operations over multiple controllers. All of these

strategies assist in improving performance.
Incorrect Answers:
C: You should upgrade from IDE and SCSI to the faster UltraDMA or Wide Ultra SCSI technologies.
