Best Raid Group size for two DS2246 shelves with 600 GB SAS disks

NEWNETAPP987

Hi,

Can someone help me confirm what the best raid group size for adding 48 new 600 GB sas disks in two DS2246 shelves would be?

 

I am thinking I would need to use RG size of 15 and then have 3 hot spares?

 

Can someone confirm this is good idea or suggest better layout?

 

Thanks,

Is this an add-on to an existing filer?   do you have spares already?  Or is this a new filer?

This is an existing filer.  We already have 4 hot spares for the 10K SAS drives.

 

I think I can just make an aggregate with RG 16, put all 48 disks in the aggregate and net out at about 20 tb of useable storage?

 

Sound good?
