Hi

I am new to netapp so apologies if these are basic questions.

With RAID DP you create multiple RAID groups of 14 disks, an aggregates is created on top of these groups and then flexvols are created within this aggregate?

If I wanted to build an array with 100TB usable capacity (an example) would I create many RAID DP groups (max disk 14/16?) with many aggregates (max size 16TB?) then create lots of flexvols within these aggregates then give hosts access to these flexvols?

What is the purpose of the root aggregate and how and when should these be created? # of disks?

Do you need a hot spare per tray or can you have global?

Also, can anyone point me in the direction of good documentation, particularly with respect to RAID, aggregates, flexvols and how they are put together with large arrays

.Many thanks for any help.
