Adding disks from different shelves

DLista

I'm preparing  a storate solution for a customer and have some doubts about disk mixing rules. From HWU, it is possible to use X477A disks on a DS212C disk shelf.

X336A = 4TB,7.2K RPM, 12GBPS, NL-SAS

X477A = 4TB, 7.2K RPM, 6GBPS, NL-SAS

 

First case:

X336A (DS212C) and X477A (DS4246 w/IOM12) disks on the same aggregate

 

Second case:

X477A (DS212C) and X477A (DS4246 w/IOM12) disks on the same aggregate.

 

Is is possible to create an aggregate with disks from both shelves? Or add capacity to an aggregate using disks from another disk shelf?

I think that's one of those, just because you can, dosen't necessarily mean you should.    


What's the overall config going to look like?  are you just adding shelves or is this a new FAS deployment.

Hi there!

 

Interesting question! It is supported to use drives from different shelves in the same aggregate and/or raid group. If HWU says the drive is supported in the shelf, then that is fine.

 

Mixing of drive technologies is not recommended, but different speed interfaces on the same drive technology should be fine. In either case, the drive will be slower than the maximum speed of the drive interfaces, and the backend connection from the shelf will still be 4x12Gbps.

 

For final answer, you should contact the partner solutions centre for your region. Please feel free to provide me your corporate contact details and I will connect you, or you can find the document on fieldportal outlining the partner solutions centers.

 

Hope this helps!
