It is good hardware/software to do VMWare backup, very reliable and convenient device. Hyper-V backup may be less appropriate to do due to specific software needs.
It is very easy to use with NFS. Creating new volumes and mounting to servers such as ESXi or Linux is a breeze. It does also support CIFS but it is far less intuitive and requires much more effort. Replicated data is also very simple and robust in the form of SnapVaults or SnapMirrors. This data is either immediately or periodically replicated to a peer FAS in the cluster for retention.
It does have a really nice and easy to use web interface to do pretty much anything you need with it. It was very simple to configure our volumes and luns and connect them to our VMWare environment using the interface. It has options to rename, shrink, grow, and other things with our luns and volumes. It was nice and easy to read graphs to see where you stand on your storage usage at a glance.
Support from Quantum was okay, they performed FW upgrade and replaced few faulty disks without any problem. Some old-style connections and requirements from them produced additional loads on our IT team.
NetApp support in Brazil is managed by its partners. We know in other countries, such as the US and NO, they have support directly from Netapp. We have a very good NetApp partner working with us since the beginning, on both the implementation and daily support. Very few cases needed to be escalated to NetApp support, most of the cases are handled and satisfyingly closed by the partner.
The only aleternative looked at prior to the DXi was ExGrid, while both are great options the DXi offered a little more versatility and the support has been terrific.
NetApp stacked nicely and gave enterprise-level usability for snapshot-based backups. Our previous RPO was several hours. It was selected prior to me arriving at the company, but It was selected for the hardware refreshes due to its compatibility with several other vendors, like CommVault and VMware.
