|

Group size must divide evenly into draid size
|
||||
E.g., 30 drives can only support
|
||||
3 drive group
|
||||
5 drive group
|
||||
10 drive group
|
||||
15 drive group
|
||||
|
||||
Only need to specify group size at creation
|
||||
|
||||
Group Size - the number of pieces the data is partitioned into plus the amount of parity
|
||||
o The amount of parity determines the redundancy
|
||||
o The number of data pieces determines the overhead
|
||||
|
||||
dRAID Size - the number of drives used for data
|
||||
(Does not include spare drives)
