mixed and sas shelves

Amir — Thu, 05 Jun 2025 05:25:18 GMT

Hi,

I've got three shelves: 2 - mixed (DS2246: 4 ssd + 20 sas), 1 - sas (DS2246: 24 sas disks).

Should I divide my shelves into different stacks?

stack 1: 2 mixed shelves

satck 2: 1 sas shelf

What document describes the stacking rules?

Thanks,

Amir

Hi,

The solution you suggested looks good for me. Putting shelves into different stacks actually avoids single point of failure.

Mixing of SSD and SAS disks in the same shelf seems to be supported from ONTAP 8.0.1 onwards, but in ONTAP 8.1.1 , a bug is fixed w.r.t this. Details here: http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=542094
