Hello Sandro Silva Alves, In your example you are wanting to know why your 10K drives are set as Tier3.  When you have more than one type of drives, you want to set your SSD as tier1 and slowest drives as tier3.  You could have set your 10k drives as tier2, however if you were to add some 15k drives then you would want them to be tier2 and 10k & 7.2 as tier3.    If you make both volumes as tier1 storage then your data will fill your SSD’s first, then will fill your 10k drives. Here is how disk spaces is managed on an SC system. All disk space is allocated into tiers. The fastest disks reside in Tier 1 and slower drives with lower performance reside in Tier 3. Data that is accessed frequently remains on Tier 1, and data that has not been accessed for the last 12 progression cycles is gradually migrated to Tiers 2 and 3. Data is promoted to a higher tier after three days of consistent activity. Disk tiering is shown when you select a Storage Type. Data Progression: Moves pages between tiers and drive types, as well as among multiple RAID levels within the same tier. Storage Profiles: Defines how data progression moves pages between tiers. Please let us know if you have any other questions.
Hi, I read about it and talked to some friends from Dell. However, I want to confirm that my understanding is correct. When I have a SC with disks of different sizes and different speeds, the correct one is following the following configuration: Tier 1 for SSD disksTier 2 for 15K disksTier 3 for 10K discs and below Remember that I need to create a disk folder by allocating the different capacity disks. Is this understanding correct? If so, I see an inconsistency in some configurations I've observed in deployments. In case the SC has 10K disks and SSD disks, for example. The implementor configured the 10K disks as Tier 3 and the SSD disks as Tier 1. There I ask! Why Tier 3 for 10K disks? Right should be Tier 2, right? And if I put Tier 1 on both albums, what would happen? The big question is that usually when SC has SSD disks, the end user has bought them for the purpose of using those SSDs for some volume that needs more speed. That is, it is the Tier that defines which disks will be used in the volume, so the need to use different Tier types in the configuration of the profiles which will be applied to the volumes? Still has the Data Progession issue ... If the end-user purchases the license from Data Progression, these settings will be critical to the operation, ie, directing unused information to slower disks. Or does not these settings have no relation? Thank you.
