The most valuable features are the snapshots, the flash pool that we’re using, and cluster mode. When we are doing an upgrade, there is less of an impact on the customer when you use cluster mode. It still has some with CIFS, but at least it has less impact.
Improvements to My Organization:
Compared to the previous solution, I would not say that it has really improved anything. We were with the HPE EVA before the NetApp. It takes more of my time to manage them, as opposed to HPE EVA, with which I created LUNs and it's done. I have a lot more tasks to do. At least now with NetApp, we can provide NAS services, which HPE EVA did not have.
Room for Improvement:
I would like to see antivirus that works, and generally a working solution. They just provided Vserver DR, which is good.
Now we need to have a way to do some tests only because to do testing we really need to failover to the second site, destroy everything, rebuild it, and failback. I really need a test mode that is not as destructive, at least. There is no test mode. Maybe there is with ONTAP 9. I’m not sure. That’s probably a feature that doesn’t figure into the short-term roadmap.
It is very unstable. We have a lot of issues with antivirus programs interrupting us from providing services to our customer. As soon as something happens with McAfee, the customer had problems with our services.
With the 7 mode, we were okay. There was a real pass-through working correctly, so if something happened with the NT file server, the files were still being served to the customer. With cDOT, it's completely the opposite. It's completely out of service. We have a lot of service impact.
We have been delaying the CIFS transition a lot because of this.
We have been using technical support for over two years regarding services been down. Support was not efficient in that case. They are available. They tried. I was supposed to have a solution with the latest version. That was last week. I did the test, but it’s still not working.
Before the admin, there was an issue, it took close to a year until a second customer had the same issue. Then, they finally admitted that I wasn't the problem. It was an issue with the software. That's certainly why I rate them poorly.
When we moved from HPE EVA to FAS, it was to have NAS services. For NAS, NetApp was probably the best one at that time.
The initial setup was straightforward. I had no problem with that.
Other Solutions Considered:
We also considered EMC at that time and HPE. For what we needed, NetApp was the best one.
The most important criteria we look for in a vendor is good service and quality of the product.
Properly define what you need first. After that, talk with people who know NetApp well, know how to set it up, and properly define the design architecture before doing it.
