What is the smallest unit of information transfer in FC?

technology storage

  1. Block

  2. Frame

  3. Cylinder

  4. File

Show answer
Correct Option: B
Explanation:

To solve this question, the user needs to have an understanding of the basic components and terminology used in Fibre Channel (FC) networks.

In Fibre Channel, data is transferred in units called "frames." A frame is the smallest unit of information transfer in FC. It contains the data being transmitted as well as control information such as headers and CRC (Cyclic Redundancy Check) for error detection.

With this knowledge, let's evaluate each option:

A. Block: A block is a unit of data storage and is not the smallest unit of information transfer in FC. It refers to a set of data, typically a fixed size, that is read from or written to storage devices.

B. Frame: This option is correct. In Fibre Channel, a frame is the smallest unit of information transfer. It contains the data being transmitted along with control information.

C. Cylinder: A cylinder is a term used in disk storage and refers to a group of tracks that are located at the same radial distance from the center of the disk. It is not the smallest unit of information transfer in FC.

D. File: A file is a collection of data stored on a file system and is not the smallest unit of information transfer in FC.

Therefore, the correct answer is:

B. Frame

What is the Default ID for SCSI HBA ?

technology storage

  1. 3

  2. 5

  3. 7

  4. 1

Show answer
Correct Option: C

AI Explanation

To answer this question, you need to understand the concept of the default ID for SCSI HBA (Host Bus Adapter).

The default ID for SCSI HBA is commonly set to 7. SCSI devices are connected to the SCSI bus, and each device on the bus is assigned a unique ID. The SCSI HBA is also a SCSI device, and it typically has an ID assigned to it as well.

The ID determines the priority of the device on the bus, with the lowest ID having the highest priority. The default ID for the SCSI HBA is often set to 7 because it is the highest possible ID value. This allows other SCSI devices with lower IDs to be given higher priority.

Therefore, the correct answer is:

C. 7

How many minimum drives are required to create R5 ( RAID 5) ?

technology storage

  1. 3

  2. 5

  3. 2

  4. 4

Show answer
Correct Option: A

AI Explanation

To answer this question, you need to understand the concept of RAID 5.

RAID 5 is a redundant array of independent disks that uses block-level striping with distributed parity. It requires a minimum of 3 drives to be created.

Let's go through each option to understand why it is correct or incorrect:

Option A) 3 - This option is correct because RAID 5 requires a minimum of 3 drives. It uses block-level striping with distributed parity, where the data and parity information are distributed across the drives.

Option B) 5 - This option is incorrect because RAID 5 does not require 5 drives. It only requires a minimum of 3 drives.

Option C) 2 - This option is incorrect because RAID 5 cannot be created with only 2 drives. It requires a minimum of 3 drives.

Option D) 4 - This option is incorrect because RAID 5 does not require 4 drives. It only requires a minimum of 3 drives.

The correct answer is Option A) 3. This option is correct because RAID 5 requires a minimum of 3 drives to be created.

Rebooting a Data Mover involves un-mounting and mounting filesystems that often consumes the majority of reboot time (more than three minutes), depending on the complexity of the configuration. A Data Mover reboot procedure that optimizes these two steps will reduce the overall reboot time including disruptions during upgrades (reboot) and recovery from fatal hardware and software events (failover or reboot for single DM).
