An existing server has three 1 TB 7200 RPM SATA drives and five empty drive bays. The network manager orders three 2 TB 5400 RPM SAS drives. The technician installs them properly, but when attempting to provision the drives, a message displays "Type mismatch". Which of the following is the reason for this error message?

Question

Accepted Answer

D. The SATA and SAS drives cannot be mixed SATA (Serial ATA) and SAS (Serial Attached SCSI) use fundamentally different electrical signaling and command protocols. While SAS controllers can sometimes accommodate SATA drives in a mixed backplane, provisioning both types together in the same RAID set or storage pool is unsupported and triggers a 'type mismatch' error because the controller cannot treat them as equivalent devices.

Answer

A. There is a firmware mismatch on the hard drives Firmware mismatches between drives of the same interface type can cause version conflicts, but they do not produce a 'type mismatch' error, which is specific to incompatible physical and protocol interface types.

Answer

B. the drives must be from the same manufacturer Drives from different manufacturers using the same interface standard can coexist in most storage systems; manufacturer homogeneity is not a technical requirement for provisioning.

Answer

C. The drive sizes must match Mismatched drive capacities affect usable space in certain RAID configurations but do not generate a 'type mismatch' error during provisioning.
