A customer has a Dell EMC Unity 680F array with a single pool consisting of 10 drives configured with RAID 5 (4+1). What is the minimum number of drives required to expand the pool?
In a Dell EMC Unity 680F all-Flash array, pools are configured as Dynamic Pools. A Dynamic Pool allows you to add drives individually. Therefore, the minimum number of drives required to expand the pool is 1.
The 680F model is all Flash so their pools are Dynamic Pools so they only need a minimun 1 drive. The right answer is A.
Minimum number of drives when creating a Pool: RAID 5 4+1 6 (4+1)+ 1 Extra Drive
I was wrong. The 680F model is all Flash so their pools are Dynamic Pools so they only need a minimun 1 drive. The right answer is A.
A Pool can be expanded by 1 or more drives – If adding a new drive type, the Pool must be expanded with the minimum amount of drives (minimum for the RAID width selected) +1 for spare space
Since it is a Dynamic pool , the expansion can be done with a minimum of 1 drives.
But it doesn't indicate whether the array is dynamic. Why is this assumed?
