Q&A Highlights
Question: What is the Biggest Difference Between Dell EMC Unity and NetApp AFF?
Answer: Well, Is one thing NetApp Storage has vs other brand is the mix of protocol CIFS with NFS booth working together in the same volume that features is difficult to find in other Storage but the flexibility that gives is a lot. Other is speed with SSDs because the latency is minimal and very helpful for higer concurrency in my case we have many concurrent connections and the metrics are very impressed with the behavior of NetApp AFF 300.
Featured Review
Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"Technical support has been amazing.""The speed is the most valuable feature, along with the ease of getting it connected. We were able to get it online in less than a day.""One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage.""The most valuable feature of Pure Storage FlashArray is its high stability level.""Because of the encryption, we have different storage and the encryption can go over both.""We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent.""The ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad.""The best feature is consistently lower latency, even when IOPS crank up to over 75K. The product maintains submillisecond response time, which is incredible."

More Pure Storage FlashArray Pros →

"The Unity XT box is very strong. It doesn't break. The MTBF time is very large so you don't have to worry about faults or outages in your operations.""We've never had an issue with storage.""It’s helped with the overall stability of our VMware environment.""After migration to Unity 300F, we were able to put more DBs on flash, reducing latency. The results were visible in the front-end systems, and all users noticed the improvement.""My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us.""It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it.""I like the easy management with the new Unisphere management and the HTML5 interface.""They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working not just for replication but for backups as well."

More Dell Unity XT Pros →

"I like NetApp AFF's deduplication.""Using System Manager for green management or command line interface, we have a single point for managing the cluster. It is much easier to manage. It is very seamless. The product is robust and solid.""NetApp is like a one-point central management. For example, one can put everything on the right version and control the whole environment from one software solution.""The most valuable features of this solution are snapshotting and cloning.""The most valuable feature of AFF is that it offers better visibility and control over performance, ensuring it meets customer needs effectively.""MetroCluster provides business continuity and is a critical part of our contingency setup.""The most valuable features are the speed and performance for our transactional workloads for our databases.""Its consistent stability is one of the things that I like, and the performance is also very good."

More NetApp AFF Pros →

Cons
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works.""We would like to integrate it more with our backup solutions.""We have not seen a reduction in our TCO nor have we seen ROI.""I feel like there is too much automation; the user doesn't have any manual input.""One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade.""The technical support is okay, but could be improved.""I would like to see support for NVMe, end-to-end.""The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."

More Pure Storage FlashArray Cons →

"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features.""It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions.""The pricing is a bit high. We'd like it to come down.""You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity.""What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps.""Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help.""I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix.""It could always use native replication. Then I could get rid of RecoverPoint."

More Dell Unity XT Cons →

"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.""The system is pretty stable but most of the ONTAP versions are not really stable. There have been multiple bugs in different ONTAP versions.""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.""FC and ATTO bridges are still needed for cross datacenter replication.""The bad part about having scalability is the expense. It is currently extremely expensive, to be able to scale so fast on flash.""It would be very useful if we could do the NFS to CIFS file transfer, but it is not supported at this time.""I need faster Fibre Channel over Ethernet. They top out at 10GBs today and I would like that to go to 40 or 100.""I would like there to be a way to break out the 40 gig ports on them. We have a lot of 10 gigs in our environment. It is a big challenge breaking out the 40 gig coming out of the filer. It would be nice to have good old 10 gig ports again, or a card that has just 10 gig ports on it."

    Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive Operations. As a benchmark let’s compare FAS to EMC’s solutions – I fully appreciate that EMC has taken a best of breed approach, but my feeling is that for most non-enterprise customers this is not a sustainable strategy – customers want simplicity and ease of use, and you are not going to get that by deploying four different storage platforms to meet your needs. I have chosen EMC because they are the overall market share leader and they have the broadest set of storage products available – so let’s compare FAS with VNX, VPLEX, XtremIO, Isilon and Data Domain: NetApp FAS supports All-Disk, Hybrid Flash and All-Flash data stores - that meet the needs of any kind of application workload The VNX is a very good All-Disk and Hybrid Flash array and XtremIO is a very good All-Flash array, but you need two completely different products to provide the functionality. NetApp FAS eliminates silos and provides seamless scalability - to address Server Virtualisation, Virtual Desktop, Database and File storage needs in one scale-up and scale-out solution, that can start small and grow large VNX is optimal for general Server Virtualisation and Databases and XtremIO excels when it comes to large scale… Read more →

    I saw that you have doubts about what you chose. I have a lot of experience with the constructor, honestly I can recommend Dell EMC Unity XT All-flash which can guarantee you a ratio of 3:1 signed by Dell and you have to deploy all types of workload from block to file. You can also rely on the native cash and fast cache functionality for increasing application performance

    This question is very dependent on your requirements. Both are among the best in the field. Of course, the intended cost is decisively based on the Gartner magic quadrant storage 2020 Net app company and Dell EMC are leaders. But we can say NetApp is First in Queue.


    One of the superiority NetApp working on NVMeOF

    The answer depends on your needs and budget. If you want high performance (who doesn't) or let's say the latency matters more than IOPS for your needs, Netapp AFF is the right choice. You can approach the max. Performance by equipping Unity with SSDs but maybe this costs more. I would recommend Netapp AFF all the time if your budget is ok.

    Frank R - PeerSpot reviewerFrank R
    Real User

    They’re both great solutions and I’ve used both.

    EMC is being VERY aggressive on pricing which may be the undoing of NetApp.

    Differences are in the user interface mostly, they both do what they are designed to do in different ways.

    I say, compare apples to apples on models and get them fighting on price.

    You win.

    First of all the decision should be taken looking at similar products in terms of capacity and performance.
    I will show a few aspects helping the decision, comparing Unity Xt480f and AFF220 (both chosen by distributor to be in the price range for capacity):

    1. Comparing 2 systems with the same capacity and performance: pricing is the first to look at:

    1a. Cost per GB, war capacity and usable capacity (+Unity)

    1b. Cost of adding capacity (+Unity)

    1c. Cost of licensing per GB / per added capacity (+Unity all included)

    1d. Cost of maintenance after initial contract (+Unity same for all life )

    2. Comparison of CPU/MEM, we choose Unity XT because of better CPU cores/frequency and memory per controller

    3. Percentage of space lost in various configurations. Our goal was to use Dynamic disk pools, available on Unity. Easier upgrades/downgrades.

    4. If virtual volumes are considered, Unity has a VASA provider included in the controller, Netapp is using external VM.

    5. Product lifecycle

    6. Inline compression / deduplication, performance,

    From the above 1=80%, 2=5%, 3=10%, 4+5=5%

    We went to Unity XT480 where on the same budget we got 20% more usable flash capacity, while enough slots remain for future upgrades.

    Reviews from Real Users

    Pure Storage FlashArray is a highly effective piece of storage technology which stands out among its competitors for a number of reasons. Two major ones are its overall robustness and the value that it offers by way of its reliability and ease of use. It provides users with many valuable features that allow them to maximize what they can do with this solution. Pure Storage FlashArray’s reliability and ease of use make it a highly valuable solution. 

    PeerSpot user Prabakaran K., a technical consultant at Injazat Data Systems, notes the robustness of this solution when he writes, "FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."

    PeerSpot user Jason D., a cloud solutions architect at a tech services company, notes three features that make this solution valuable when he writes, "We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."

    Reviews from Real Users

    Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

    A Systems Engineering Manager at a manufacturing company says, "It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

    Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

    PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."

    Reviews from Real Users

    NetApp AFF stands out among its competitors for a number of reasons. Two major ones are its high performance and simplicity. PeerSpot users take note of the advantages of these features in their reviews:

    PeerSpot user and Storage Administrator, Daniel Rúnar Friðþjófsson, comments “AFF has helped to simplify our infrastructure, while still getting very high performance for our business-critical applications. Having all these things working well on one solution is really good. We run this as the backbone for both Hyper-V and VMware as well as an archive location for Rubrik. So, it is great having one solution that can do it all.

    Because of the ease of it all, you have a highly tunable, high-performance storage system that alleviates a lot of problems. With its ease of management, you can quickly get your work done and go onto the next thing on your list.”

    Additionally, Mohan Reddy, Sr. Technology Architect at a Pharma/Biotech company comments on how “NetApp's ONTAP data management software has also made tasks simpler for us. There's no question about that. It has helped us run operations very quickly, saving us a lot of time. Before ONTAP, we used to spend a long time doing regular operations, but with the latest version of the tool, our day-to-day operations are much quicker and easier.”
