Netapp Flexgroups

Post by 225enginner » Nov 20, 2018 6:12 pm

Netapp introduced Flexgroups in Oct. 2017. Veeam integration can see the old Flexvol but does not show any Flexgroup volumes. I need a developer to look at the logic of the SAN Scan function and see how FlexGroups can be detected. This Flexgroup is an NFS export just like my other Flexvol's.

Hello,

NetApp FlexGroups as of today are not supported and recommended for any other workload than scale-out NAS.
That said, using FlexGroups to store VMs is nothing we would recommend to do as of today.
More infos here: http://docs.netapp.com/ontap-9/index.js ... 05146.html

Furthermore, most of the features used for backup and restore tasks such as FlexClone are not available with FlexGoups today.
See the Supported and unsupported configurations for FlexGroup volumes here: http://docs.netapp.com/ontap-9/index.js ... 7BE0C.html

So my questions is, like as what Melissa asked, for which use case are u using FlexGroups today?

Snapshots but not FlexClone means restores can only be done in a read-only fashion, manually copying out the read-only VM to a regular datastore volume?

There is no general statement here.
I personally would say, FlexClone is a must if you want to use the full feature set veeam offers.

All other use cases in terms of licensing are documented here: https://helpcenter.veeam.com/docs/backu ... tml?ver=95

Too much to write here.

Please understand that this sitaution is unsupported as NetApp do not support it and do not give us needed APIs or functionallity for it.

NetApp can help I guess with the manual VM restore tasks. It would maybe make sense as well to place a feature request at NetApp to support VMs on it if there is a usecase for it.
As I was told the FlexGroups was introduced for billions of files unstructured data volumes to optimize metadata handling.

Overall I suggest to bring the NetApp in a NetApp (and therefore Veeam) supported configuration to not run into unplanned issues where nobody can help you with issues.

Certain NetApp models have a 100tb volume limit. I need flexgroups so I can retain more than 100tb of snapvault snapshots.

Thanks this is valuable feedback and we will discuss with NetApp in our call.

Nevertheless it is an unsupported situation from NetApp side and you should contact them to discuss. If NetApp change this and support full stack of features with it then we can support it.

In the meantime you can use the standard VMware backup methods (DirectSAN/HotAdd/DirectSAN/DirectNFS) to backup the VMs with Veeam without storage integration.
