Hello,  Re: 1.  Yes. A volume will occupy both the SAS and SSD RAIDsets automatically.   Re: 2.  No. However, writes favor the SSD, then a larger portion is sent to the SAS RAIDset.  Re: 3.  No.  Tiering refers to data distributed to different members in a given pool.  Regards, 
Noob to the EQ line and would like to know a couple things regarding the hybrid array:  * 6110xs is part of a group but in its own pool* 1. When creating a new volume does it auto-tier between SAS and SSD drives by default? 2. If so, is there a way to limit a volume to only be on either the 10K SAS or SSD drives? 3. If not, how does one configure auto-tiering for a particular volume? That is it.  Thanks,  David
