Understanding the configuration of an SC3000 or higher

Hi,

I read this documentation and a question came to me.

Suppose we have a SC with the types of disks: SSD, 15K, 10K and 7.2K.

The client wants to work with the following configuration:

1 - Basic servers will use the 10K and 7.2K disks;
2 - File server will use the 15K disks;
3 - DB server will use SDDs;

No date progession

We will apply the following settings in SC:

1 - Different folder folders for SSD, 15K and 1OK and 7.2K disks;
2 - Storage Profile Tier 1 for SSD, Tier 2 for 15K and Tier 3 for 10K and 7.2K.

- When creating volumes for the basic servers I apply the Tier 3 profile;
- When creating voluems for the file servers I apply the Tier 2 profile;
- When creating volumes for the DB servers I apply the Tier 1 profile.

Then the questions arise:

1 - If the space of the Tier 1 disks ends, even if it dates progression will the data begin to be written on the Tier 2 disks and so on?

2 - Could I use this scenario with date progression? If so, would the data be migrated from Tier 1 to Tier 3 directly without Tier 2?

3 - Does this mean that the Tier 3 space should hold all Tier 1 and Tier 2 workloads, since they can be migrated to slower disks?

Thank you.
