Find out what your peers are saying about Dell EMC Unity vs. NetApp AFF (All Flash FAS) and other solutions. Updated: September 2019.
372,124 professionals have used our research since 2012.
We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
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 most valuable thing for our use case is the flexibility to have multiple-protocol support.
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.
The valuable features are the fabric pool. We are taking our cold data and pumping it straight into an estuary bucket. Also, efficiency. We're getting about two and a half times upwards of data efficiency through compaction, compression, deduplication, and it's size. When we refreshed from two or three racks of spinning discs down into 5U of rack space, it not only saved us a whole heap of costs in our data center environment but also it's nice to be green. The power savings alone equated to be about 50 tons of CO2 a year that we no longer emit. It's a big game changer.
The features that I found most valuable are SnapMirror and SnapVault; these provide DR and backup for data redundancy.
Its efficiency and scalability are the most valuable features.
The most valuable features for AFF are the speed, durability, back up, the time, the workloads that we are using currently are much faster than what they used to be. We're getting a lot of different things out of All Flash.
Previously we had migrated from Dell EMC and we had a lot of difficulties moving data around. Now, if we need to move it to any slower storage, we can move it with just a vault move within the cluster. Even moving data between clusters is extremely simple using SnapMirror. The mobility options for data in All Flash FAS have been awesome.
NetApp tech support is so good. Their tech support has always been so stable and the people are so good in case of any failure or any good feature that needs to be updated or features that supposedly can help with performance to improve some performance. NetApp support is one of the best that I deal with.
Scalability is excellent. If we need more space, it's a no downtime solution. It's harder to get the funding than it is to get the solution itself.
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.
I would like to have secure mobile connectivity going forward. This would help me be more proactive.
The total cost of ownership has increased a little.
I would like for them to develop the ability to detach the fabric pool. Once you've added it to an aggregate it's there for life and it would be nice to disconnect it if we ever had to.
I would like to see an improvement in the high availability of the NFS and CIFS sharing during upgrade and patching; this would help to avoid downtime.
The scaling needs improvement. NetApp is limited for scaling options.
The bad part about having scalability is the expense. It is currently extremely expensive, to be able to scale so fast on flash.
As for AFF itself, I don't have any suggestions of what I would be excited about seeing. I think that adding the support for the rest of APIs to AFF would be super handy. I think it's something that we've been waiting for for a while which would be fantastic.
I would like to see the ability to include more applications from applications to managed storage. If we can have more applications or more interface in more applications, that would be great.
I come tech support with difficulty because I installed NetApp for many years I know what to expect when I call. When I don't get their support tech that I'm expecting and I'm trying to get to the right one, it can get very frustrating for me personally, trying to all-flash push my way into the right person. NetApp has the right people, it's just a matter of getting to them.
Pricing and Cost Advice
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.
With other options, you need to buy a couple of different products to achieve the same outcome.
Our TCO has increased by 15 to 18 percent.
Using NetApp, our total cost of ownership decreased by 17%.
Our TCO decreased significantly because we were paying maintenance on nine different arrays throughout the country. We've condensed those down to three arrays, and our maintenance fees from the IBM product dropped by over a half million dollars a year, saving us $500,000 USD.
The total cost, the pricing of it, has gone up quite a bit.
Disk level encryption is already in the solution, but it is very costly. Its pricing should come down.
From an application standpoint, we have seen a lot of return investment on the speeds and responsiveness of the actual storage.
Our total cost of ownership (TCO) has decreased by 40 percent.
