Something I thought was not possible...

[Falloutboy]

I have been reading in quite a few places that a sas controller can not support mixed topology on one SAS connector ergo when you have an IBM M1015 that fans out two sas connectors to whatever ( in this case ) four sata cables and they are plugged into a backplane cage that you can not have SAS hd's and sata hd's working on that one cable set - yet I have done this.
I have two HGST SAS drives on P3, P4 and a Seagate SATA drive on P2.

Can anyone tell me why this isn't meant to work?

It should work. The fact that you are using multilane cables really makes no difference. A lane is a lane, no matter the physical interface.

Yes sata drives and sas connected to the same multilane sas connector works.

What you read about sas & sata is that it's not recommended to use sas and sata devices in same array/logical volume as sas drives behave differently than sata drives. (Some GUIs like adaptecs maxview won't allow you to create such a volume, but cli works.)

It'll work

Thanks for the info guys.

Thanks for the info. I also thought I had read the same thing that you couldn't mix sas and sata on the same controller.
