We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
Things that have been really useful, of course, are the clustering features and being able to stay online during failovers and code upgrades; and just being able to seamlessly do all sorts of movement of data without having to disrupt end-users' ability to get to those files. And we can take advantage of new shelves, new hardware, upgrade in place. It's kind of magic when it comes to doing those sorts of things.The ease of use, the SnapMirror capabilities, the cloning, and the efficiencies are all good features.We are using the AQoS operating system, which allows us to get a lot more out of our AFF systems.The most valuable features are the ease of administration and configuration, as well as the speed of deployment.The most important features are the IOPS and the ease of the ONTAP manageability.Before we implemented AFF, Oracle was running on a traditional storage spindle and at a very low speed with high latency, and the database was not running very well. After we converted from the spinning disk to the all-flash array, it was at least four times faster to access the volume than before.The most valuable features of the solution are speed, performance, and reliability.The most valuable feature is speed.

This product is perfect for small, and mid-range customers who need to pay less, but still, get enterprise-level capabilities.This solution makes it easy to manage storage, provision new workloads, and scale-up.The All-Flash models are pretty fast for the vast majority of our remote workloads.We use replication for disaster recovery (DR), making our DR process much easier.It has reduced complexity.We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint.It has good performance.We can get almost real-time response times.

The solution offers very good reliable systems and storage for our clients.Ability to cluster two storages together with HA availability.We are satisfied with the stability.We prefer the SR650 server system. This version fits our customers' needs best. That's the latest update that we can try to give them.The FlexClone feature is the solution's most valuable aspect.

Cons
One of the areas that the product can improve is definitely in the user interface. We don't use it for SAN, but we've looked at using it for SAN and the SAN workflows are really problematic for my admins, and they just don't like doing SAN provisioning on that app. That really needs to change if we're going to adopt it and actually consider it to be a strong competitor versus some of the other options out there.There are little things that need improvement. For example, if you are setting up a SnapMirror through the GUI, you are forced to change the destination name of the volume, and we like to keep the volume names the same.The quality of technical support has dwindled over time and needs to be improved.On the fiber channel side, there is a limit of sixteen terabytes on each line, and we would like to see this raised because we are having to use some other products.The certification classes are good, but they don't cover enough of the material, and the exams only test on what is covered in class.The monitor and performance need improvement. Right now we are using the active IQ OnCommand Unified Manager, but we also have to do the Grafana to do the performance and I hope we will be able to see the improvement of the active IQ in terms of the performance graph. It should also be more detailed.Tech support is a place where there is room to improve the product experience. The response time when they are busy is not very good.The price of NVMe storage is very expensive.

This product needs to have better integration with enterprise backup solutions and archiving devices.This solution would be improved with the addition of flexible raid volumes.We would like to see the concept of Storage Groups brought back to this product line.I haven't seen the roadmap for this solution.It is missing some features, like deduplication.Because we can do synchronous replication between the two sites, this made the setup challenging for this piece. They did not know how to set this up initially. We ended up having to do bidirectional synchronous replication.I would like them to continue to build on the solution and expand on the functionality, like replication.We'd like to see a cheaper version of an all-flash array in that footprint.

The licensing model needs to be revisited. It needs to be simplified.This is an expensive solution.It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved.Technical support could be improved for this solution.The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features.

Pricing and Cost Advice
It's expensive. it's in the hundreds of thousands. It's beneficial, but at times, I feel compared to other vendors, we are paying a premium for the licensing that other vendors include.The price to performance ratio with NetApp is unmatched by any other vendor right now.The pricing is not a lot considering what you get and it bundles hardware and licensing.Comparing this solution to others it may seem expensive, but the price to performance for NetApp is greater.We would like it to be free.One of the reasons we like this solution is that all of the features are included with the one license.We don't like the cost. We would like to buy more.It definitely reduces costs because it simply takes less power to run these systems. While the SSDs don't take power, they are in general very big right now. So, the running cost has decreased for a lot of our customers.

Our CAPEX was close to $42,000 and operating costs are below $1000.Our costs are roughly $200,000 a year.The solution is extremely functional for the price that we pay for it. It is worth the investment.We purchased a five-year warranty.Compression is making a difference towards the amount of hardware that we need to purchase.The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes.It scales, but then you have to buy additional stuff.With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity.

We can try to make a good offer for our customers, but in Turkey the difference between the dollar and Turkish lira is very high. Pricing is the hardest part of my job, because the price is very high for our customers. We try hard to make the price low for our customers.
