When preparing to add new SCSI hard drives, which of the following should you be aware of if you have existing older SCSI devices?
A.
You need to be aware that all devices, both current and new, will operate at the lower performance levels of the older devices.
B.
You need to be aware that all new devices will attempt to operate at the higher performance levels, and the older devices will continue to operate at their lower performance levels.
C.
You need to be aware that all new devices, as well as the older devices, will operate at the higher performance levels of the new devices.
D.
None of the above
Explanation:
When upgrading SCSI devices, you need to bear in mind that all new devices will attempt to operate at the higher performance levels and the older devices will continue to operate at their lower performance levels. This type of situation can lead to less than optimal operations. To avoid this, ensure that the controller is slowed down to cater for your older devices. In addition to this, an updated SCSI device can only operate at the maximum performance level of the adapter in a system.
