Hello,

I have purchased a ME4024 SAN and ME424 enclosure.

The ME4024 was filled with SSD 1.9TB drives and the 424 was filled with SAS 15k 900gb drives.

I went with the recommendation that the SAN wizard felt was appropriate as follows-

Chose the virtual setup over the linear setup.

12 SSD and 12 SAS in Pool A and then 12 SSD and 12 SAS in Pool B.  Chose ADAPT for raid level.

For right now I only have 2 volumes, one on each pool.

My question is this, does the san auto tier by volume or by the data that is within the volume?  For example, if I had multiple volumes consuming the san, would it auto tier by placing the volume itself on to the SSD drives -or- is it possible that some data on a volume lives on SSD and some data in the very same volume live on SAS?

Thanks.
