- Clustered Data ONTAP
- Snapshot implementation for SAP
It allows us to shrink the maintenance windows and downtime. It provides faster replications between systems because of the installed flash.
ONTAP has a lot of features that are really great, so I don’t think there is something missing that I'd like to have.
However, the best way to improve would be to have better management over the solutions globally (not a part of the software OnCommand, VFA, etc. installed). It would be great to combine all the software solutions together under a single GUI and people can just activate different features as they buy a license as apposed new installs each time.
We've been using it for four months in a multiple system environment with a lot of small writes. This was installed for an SAP HANA system as the persistency layer.
There has been no downtime yet -- perfect stability.
It scales to our needs.
We didn't have anything similar in use previously.
It's a straightforward and easy setup. It was guided and we had the documents to install it. It took around two days of racking, stacking, and installation.
I did the implementation myself.
We looked also looked at EF from NetApp and chose AFF because of the snapshot technology.
It's definitely worth it if you need the speed.
