Hi,
we are changing our storage to a new NetApp. We are now creating our storage design and i wan´t to know if someone could share his experience with the different capabilities to configure the storage. Until now, we are not using Backup technics like snapshots.
Thin FlexVol -- Thin LUN -- Thin VMDK
Thin FlexVol -- Thin LUN -- Thick VMDK
Thick FlexVol -- Thin LUN -- Thick VMDK
....
I know that the best storage savings you are getting with all thin. But it is also a dangerous one.
For us, i think about the following options
Thick FlexVol -- Thin LUN -- Thick VMDK
- Never overprovision Aggregat and therefor there is no posibility of all LUNS offline.
- Good to save storage from LUNs you never touch. Like the last 10 - 15 % of space.
- you are able to create new LUN´s in your FlexVol because of dedup saving.
Thin FlexVol -- Thin LUN -- Thick VMDK
- Best to create new Vol and / or luns because of disk savings with dedup.
- On the other hand, keep in mind to monitor your storage
- Good to save storage from LUNs you never touch. Like the last 10 - 15 % of space.
Thick FlexVol -- Thin LUN -- Thin VMDK
- What about performance with Thin VMDK? VAAI? Metadataupdate?
- Good to save storage from LUNs you never touch. Like the last 10 - 15 % of space.
- Until now, i am not often using Thin VMDK, only some Server.
