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

Pros
"Tech support has been absolutely amazing. I think on the technical aspects as well, my staff is able to get great support from the NetApp technical support resources that we have. What I love about NetApp is they have a health care division. At times, it's such an amazing thing because if we have a healthcare-related issue, there's no one better than having prior CIOs from health care organizations that NetApp has hired, and that are part of the health care team, to help out with any of those initiatives and support problems. Support has been absolutely phenomenal.""This solution has reduced our data center costs because when we went from the 8000 and 3200 series that took us from 20 racks of storage down to two.""The solution’s thin provisioning has allowed us to add new applications without having to purchase additional storage. We use thin provisioning for everything. We use the deduplication compression functionality for all of our NetApps. If we weren't using thin provisioning, we'd probably have two to times more storage on our floor right now than we do today.""The most valuable features of this solution are the deduplication and the ability to move data to different clouds.""The most valuable features of this solution are snapshotting and cloning.""The overall latency in our environment is very low because it's All Flash and we've got 10 Giga dedicated to the storage network""Speed, reliability, ease of use are the most valuable features.""Our AFF 8040 is currently helping us in terms of response time and speed because it is a flash system. Most importantly, it enables our SQL Cluster to respond to database queries and things a lot faster. It minimizes latency."

More NetApp AFF (All Flash FAS) Pros »

"The All-Flash models are pretty fast for the vast majority of our remote workloads.""This solution makes it easy to manage storage, provision new workloads, and scale-up.""This product is perfect for small, and mid-range customers who need to pay less, but still, get enterprise-level capabilities.""Integration is easy with this product.""The most valuable feature is the integration with vCenter."

"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration.""The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate.""Stability-wise, this solution is fine.""The feature I find most valuable, is the deduplication, because the nature of the data that we are using in our current environment, has a lot of replicated data.""We are a 100% satisfied with the stability of the solution.""The most valuable features are deduplication and compression.""The ability to create LUNs and modify them are the most valuable features of this solution.""The most valuable features are deduplication and compression, which together, enable you to have more space."

Cons
"The total cost of ownership has increased a little.""We would like to have NVMe on FabricPool working because it broke our backups. We enabled FabricPool to do the tiering from our AFFs to our Webscale but it sort of broke our Cobalt backups.""Something I've talked to NetApp about in the past is going more to a node-based architecture, like the hyper-converged solutions that we are doing nowadays. Because the days of having to buy massive quantities of storage all at one time, have changed to being able to grow in smaller increments from a budgetary standpoint. This change would be great for our business. This is what my leadership would like to see in a lot of things that they purchase now. I would like to see that architecture continue to evolve in that clustered environment.""It would be very useful if we could do the NFS to CIFS file transfer, but it is not supported at this time.""The cost of this solution should be reduced.""It has not reduced our data center costs. NetApp charges a pretty penny for their stuff.""We have had issues with CIFS presentations and outages, so if that was removed, we could do seamless upgrades without affecting CIFS presentations. That would be an advantage. That's about the only improvement I can think of.""We currently use some thin provisioning for our planning system, but we will probably move away from thin provisioning because our Solaris planning system actually has some issues with the thin provisioning and way Solaris handles it, since Solaris uses a ZFS file system. The ZFS file system doesn't like the thin provisioning changing things and it brings systems down, which is bad."

More NetApp AFF (All Flash FAS) Cons »

"We would like to see the concept of Storage Groups brought back to this product line.""This solution would be improved with the addition of flexible raid volumes.""This product needs to have better integration with enterprise backup solutions and archiving devices.""Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment.""Support Responsiveness & time to fix bugs should be improved."

More Dell EMC Unity XT Cons »

"The solution is not able to replicate data in one-to-many scenario.""The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general.""This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method.""I would like to see an improvement in the handling of large amounts of rights.""I think the only thing the developers can look at, is that it is limited to 25 gigabytes currently. In the next release they might want to increase that.""The ease of installation should be improved. We had issues with the configuration model.""Enterprise data storage needs improvement. They should create a feature for data and file storage.""The security features can be improved such that the encryption does not affect performance in any way."

Pricing and Cost Advice
"The pricing is good.""It consolidates a lot of our storage into one or two chassis, which makes money savings in our data center.""We have used the solution’s thin provisioning to add new applications without having to purchase additional storage. We use thin provisioning on all of our flash arrays at this point. It gives us the choice to be able to overprovision and take advantage of compression, compaction, and thin provisioning all at the same time. We can get more out of the purchases that we make.""I would like it to be a lot less expensive, but it's been a very good solution for us.""The price of the upgrading of the solution is high. I could buy a whole unit of All Flash FAS 300 with a shelf for around $285,000. Yet if I want to add one additional shelf, it'll cost me $275,000. So they want you to upgrade by replacing it. It's cheaper to buy a whole new unit than to just scale out. The upside is they last. AFF lasts us three or four years. So that's a good investment.""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.""One of the reasons we like this solution is that all of the features are included with the one license.""We would like it to be free."

Information Not Available
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included.""The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go.""They've been much more aggressive in the last five, six years than they were before that.""This is an expensive product and if the price were reduced it would be better.""Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions.""Its price is very good.""I find the pricing of the solution to be very reasonable.""You purchase it as a bundle and the price is comparable."
