Take Disk Storage to the Next Level with SAS

[BrendonHiggins]

The link to communities site did not work for me so I have created this thread.

Anyway http://www.netapp.com/us/communities/tech-ontap/tot-sas-disk-storage-0911.html is a good read.  From a design point of view, what size disks can I use in the new DS4243 shelf and what sort of raid groups should I use for performance or maximum usable capacity?  The 16 Tb limit is still an issue on 7.3.2 and with 10 shelves of 24x 300 Gb drives.

Found this link on toasters

But it would be nice if NetApp were to post best practice.

According to the configuration guide for ontap 7.3.2:

SAS: 300 GB and 450 GB

SATA: 500 GB and 1 TB

The normal raid group sizes will apply.

BTW: you will also need additional SAS expansion card(s) in your controller.

Thanks to the magic of RTFM...

Includes the new disk sizes too.
