Question

A company is planning to deploy data tiring in a SAN environment. They need a solution that provides the maximum performance for the first tier and the maximum capacity for the second tier. Which drive types should the company use? (Select two.)

Options

  • Anear line (SATA)
  • Bsolid-state drive (SSD)
  • Cserial-attached SCSI (SAS)
  • DFibre Channel (FC)
  • EFibre-attached ATA (FATA)

Why each option

Storage tiering pairs the highest-performing drive technology for tier one with the highest-capacity, lowest-cost drive technology for tier two.

Anear line (SATA)Correct

Near-line SATA drives offer the highest storage density and lowest cost per gigabyte among available drive types, making them the best choice for the second tier where maximum capacity is the primary goal.

Bsolid-state drive (SSD)Correct

Solid-state drives deliver the highest IOPS and lowest latency of any available drive technology, making them the optimal selection for the first performance tier in a SAN tiering architecture.

Cserial-attached SCSI (SAS)

SAS drives offer good reliability and rotational performance but are outperformed by SSDs and do not deliver maximum capacity at the lowest cost compared to near-line SATA.

DFibre Channel (FC)

Fibre Channel drives spin at high RPM and provide low latency for mechanical media but cannot match SSD performance and are more expensive per gigabyte than near-line SATA.

EFibre-attached ATA (FATA)

FATA drives combine a Fibre Channel interface with ATA platters, offering moderate capacity and moderate performance, but are not the maximum in either category.
