An administrator is configuring RAID 1 in a server. The administrator has been given two matching 80GB SATA-2 hard drives, two SATA-2 cables, and a SATA-2 RAID adapter. How should the administrator…

The correct answer is B. Install one drive on the first cable, on the first channel. Install the second drive on the second cable. To configure RAID 1 with SATA drives on a RAID adapter, each drive should be connected to a separate cable and channel on the adapter for optimal performance and redundancy.

Question

An administrator is configuring RAID 1 in a server. The administrator has been given two matching 80GB SATA-2 hard drives, two SATA-2 cables, and a SATA-2 RAID adapter. How should the administrator BEST configure these drives?

Options

  • AInstall one drive on the first channel and install the second drive on the second channel.
  • BInstall one drive on the first cable, on the first channel. Install the second drive on the second cable,
  • CInstall both drives on the same channel. Cable both drives as the primary master on the same cable.
  • DInstall both drives on the same channel. On the same cable one drive should be set as primary slave

Why each option

To configure RAID 1 with SATA drives on a RAID adapter, each drive should be connected to a separate cable and channel on the adapter for optimal performance and redundancy.

AInstall one drive on the first channel and install the second drive on the second channel.

While distinct channels are good, the phrasing is incomplete as it doesn't explicitly mention separate cables, which is standard for SATA, and option B provides a more complete and accurate description.

BInstall one drive on the first cable, on the first channel. Install the second drive on the second cable,Correct

For SATA drives connected to a RAID adapter, each drive should ideally have its own dedicated cable and connect to a distinct port (channel) on the adapter. This configuration ensures independent communication paths for both drives, maximizing performance and reliability for the RAID 1 array.

CInstall both drives on the same channel. Cable both drives as the primary master on the same cable.

Connecting both SATA drives to the same cable and configuring them as primary master is incorrect; SATA uses point-to-point connections and does not support master/slave configurations or multiple devices on a single cable like PATA.

DInstall both drives on the same channel. On the same cable one drive should be set as primary slave

Connecting both SATA drives to the same cable with one as primary slave is incorrect because SATA does not use master/slave jumpers or share cables between devices.
