It saves us time, it does not require a lot of admin from us. We are looking for things that we don't have to spend a lot of time managing. This solution falls into that category.
It is easy to use. Setting up replication is pretty simple. We just set it and forget it.
I'm not sure if it has a single pane of glass management console. That would be something we would like to see. Managing as many platforms as we do, as many physical devices as we have, anything that can provide a single pane of glass would be a huge benefit.
We're happy with the stability. We have not had any issues with it. We run all-flash on two of them and, so far, we have not had any complaints about performance issues.
Other than upgrades, I have not had to use tech support. When I have had to do upgrades, they have been responsive, and easy to get to.
We are replacing our VNXs with it. Performance-wise, it has been pretty stable. The code upgrades are fairly simple and straightforward. I can't say it has had any issues so far.
When selecting a vendor, product stability is the big thing, but support is probably right up there with it.
I would use this solution over most VNX solutions. It is right up there. We have some Pure Storage, so it is somewhat in contention with that. We are mostly an EMC shop, so that's probably our biggest deciding factor. If you're an EMC shop, I would definitely go with Unity. If not, which you go for will probably be in the middle. Pure probably has the ease of use down a little bit better than Unity, but I would ding their support much more than anything I've done with EMC.
