RAID Recovery Course - Overall Test
What does content analysis help determine?
RAID level
disk order
block size
Check what ratio of zeros helps exclude
damaged disks
stray disks
RAID5 disks
hotspare disks
blank disks
What is the correct order of the content analysis stages in ReclaiMe Pro?
mirror analysis, ratio of zeros, parity analysis
ratio of zeros, mirror analysis, parity analysis
parity analysis, ratio of zeros, mirror analysis
Look at the picture on the right and guess the possible RAID level
RAID 5 with a missing disk
Full RAID 5 with a hotspare
RAID10
Full RAID5
When to apply parity analysis?
after zero and mirror analysis
after entropy analysis
between zero and mirror analysis
before zero and mirror analysis
Look at the picture on the right and guess the possible RAID level
Full RAID6
RAID6 with a missing disk
Full RAID 6 with a hotspare
RAID 5 with a blank disk
When to apply entropy analysis?
after content analysis
between zero and mirror analysis
before content analysis
Check what you can get with entropy analysis
spot synchronous RAIDs
block size
disk order ideas
spot asynchronous RAIDs
original number of disks
Check what you can do with entropy analysis
notice that start offset doesn't equal zero
detect the first disk in the RAID
spot the disks which do not form a parity-based array
spot the disks which do not belong to the RAID in question
Look at the picture on the right and choose the most complete configuration
full 4-disk RAID5, 16 KB block size
full 4-disk RAID5, 32 KB block size
4-disk RAID5 with one disk missing, 32 KB block size
full 4-disk RAID5, 64 KB block size
