Node Root Vol - Importance of disk speed/spindle count

Hi,

 

Are there any situations where it is advantageous to place the node root vol on SAS disks versus SATA disks?

 

 

I understand the requirement to isolate node root vol to its own aggr so that there is not any I/O contention and so that cluster database can sync before data vol givebacks but I'm not knowledgeable enough about the node root vol role in other operations  and the corresponding I/O that might be generated.

 

 

My setup will look something like this:

 

Cluster-Mode Ontap 8.2

FAS 3220 (2 Node)

 

2 Shelves of 24 x 600GB 15k SAS

12 x 100GB SSD

36 X 1TB SATA

 

 

Thanks in advance,

 

Tim
