RAID Recovery Course - RAID Levels Test
In a RAID6, Q-parity function is always calculated over data blocks and P-parity block in a row
Which controller uses non-typical RAID6 layout – wide pace?
Check RAID level utilizing dedicated disk to store parity
What is hotspare?
disk storing a copy of parity data
disk storing a copy of RAID data
blank disk already installed in a RAID in anticipation of a member disk failure
Check the correct statements relating to a hotspare
hotspare can be either a standalone hard drive or be integrated into a RAID
hotspare is always integrated into a RAID
hotspare is always a standalone hard drive
hotspare drive may contain non-zero data
Is it possible to recover data if one of the member disks in a RAID10 failed?
yes, but only part of the data is recoverable
yes, all data is recoverable
depends on which disk failed
Check non-block RAIDs in the list
Check what delayed parity means
data blocks are larger than parity blocks
parity blocks are delayed within one of the member disks
parity blocks are larger than data blocks
What controllers use delayed parity?
Asynchronous RAID is the same as asymmetric RAID
