RAID Recovery Course - RAID Introduction Test
Check the reasonably acceptable RAID block sizes
Check those which can be RAID parameters
Is it obligatory to use identical disks to create a RAID?
What is start offset?
offset at which RAID user data starts
offset at which RAID metadata starts
What typical values for block size in RAID?
up to 1 MB
up to 1 KB
Should start offset be equal to block size?
What represents member disks in the RAID block layout diagrams?
Speed improvement is achieved due to the fact that:
data on a RAID is not fragmented
two data blocks on two disks can be read in one operation
each member disk in RAID is faster than a regular hard drive
What type of the device can implement exotic RAIDs?
More complex RAIDs have more parameters
