Hi,
We have a MSA02040 running with spinning disks, and I am interested in buying the Automated Storage Tiering license and a few SSD's to beef it up a bit. Currently I have 2 (linear) vdisks on their own set of disks. This is on purpose; I want that data to be seperated for both performance and disaster(recovery) reasons. I know the approach of tiering is conceptual different from linear vdisks but still I want to keep my data seperated in two seperate group of disks.
Now when I read the sparse documentation available on Automated Storage Tiering, it seems you have to create a tiering group and add disk-groups in that. Pretty obvious. However what I am not able to find proper documentation on is if I can create multiple tier groups, each with their own performance (SSD) tier / diskgroup and have the automated storage tiering keep data inside each tier, so if one tier goes bad for whatever reason the other keeps running? Is it even possible at all to have tiering working on multiple tiering groups?
