Sales Manager at Multicomputos PR

Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Efficient and straightforward setup boosts data management capabilities

Scalability is a significant feature of Dell XtremIO, as it is easy to expand and manage. It provides a lot of features suited for complex systems, such as scalability and the ability to define multi-domain systems, which are beneficial for data management and storage separation. It is efficient from the customer's point of view, offering deduplication at both the volume and file levels. The configuration and setup are straightforward, provided one has knowledge in setting up network infrastructure like VLANs. It is easy to install, use, and configure, making it a reliable product.

Owner at RTX

Flexible with great support and high-speed multi-protocol storage

Keystone offers flexible consumption models that go beyond just how much capacity at such and such a speed, et cetera. We don't always know what the profile of that data will be. However, if we can quickly agree on terms that meet our needs and make NetApp still reasonably profitable, we can confidently deploy, see how things go and adjust. That kind of service delivery model, that customer service model has sped things up and made contract negotiations much easier. It frankly made the owners of the system more confident. We've experienced faster time to market. It's hard for us to find and retain infrastructure staff. We're in a business where the firm fixed price contract reigns supreme, and so we can't always just offer someone more money. However, if they can dedicate their time to learning one company's portfolio and learning it really well, but be useful in a bunch of different places, they will do well. We've seen that in a lot of different places. We've been able to hire younger people and retain them, moving them from program to program based on their understanding of the solution its skill set, and its portability. It's been useful for high-speed multi-protocol storage in places with ever-increasing density. We have limits on how much power and cooling and rack space we have, and yet they've delivered every time. We needed a storage company that had mastery of multi-protocol, and this solution stands out. They especially stand out as a secure provider. We require solutions that we can run ourselves, that we can air gap since so much of what we do is either classified or very sensitive or cannot live in a public ecosystem. For us, the issue consuming AI has been the trust of the models given to us by third parties. We can't necessarily trust their provenance, what fed them, what originally trained them, or what gave them their worldview, for lack of a better term. We can't simply just trust that at face value since we know nothing about where it came from or what inferences it might make. We must assume that some AI inferences were made deliberately to damage or hurt national security systems. So the models that we start with tend to be very, very primitive, crude, and not well trained, so we have to train them much longer and not always with the availability of cloud that has inexhaustible capacity. A partner who understands this and provides consistency at all scales is very important.

Quotes from Members

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

Pros

"The latency is good."

"The most valuable feature of this solution is reliability."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

"The most valuable feature of this solution is its ease of use."

"The solution is scalable."

More Pure FlashArray X NVMe pros

"It is scalable."

"Xtrem10's features are more simple to implement. The integration and interface are also good."

"The initial setup is straightforward."

"It was very easy and straightforward to setup."

"Speed and reliability:"

"The speed and scalability of Dell XtremIO are significant features that improve data storage management."

"The speed is extremely valuable."

"XtremIO is very stable."

More Dell XtremIO pros

"The most valuable features are the flexibility and level of technical support."

"It's very stable. It's always there when we need it. With the Dual Controller, if one drops out, the other one comes right online. We don't use any iSCSI so there is a little bit of a latency break but, over the NFS, we don't notice that switch-on. We can do maintenance in the middle of the day, literally rip a whole controller out of the chassis, and do what we need to do with it."

"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."

"We have a comprehensive solution that could accommodate anything. We can fly it earlier and get them in the air testing and prototyping much faster than they could have with other solutions."

"The most valuable aspect of NetApp AFF is the money it saves our organization."

"NetApp AFF has helped to simplify our clients' infrastructure while still getting very high performance for their business-critical applications. One of our customers uses the vSAN environment in the release, then they use NFS for their VMware VCF environment and TKG environment. In this case, when they move to NetApp for the TKG and the VM infrastructures, they use AFF for block, CIFS, and NFS. It provides a single storage with NFS, block, and CIFS with deduplication, team provisioning, and compression. Everything is in there, which makes it very good to use."

"It supports our virtualization, our VMware environment."

"The features that I found most valuable are SnapMirror and SnapVault; these provide DR and backup for data redundancy."

More NetApp AFF pros

Cons

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"They could add more support for file storage and different types of storage."

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

"The tool's portfolio is minimal. It is expensive."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"In the future, I would like to see integration with enterprise backup systems."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

More Pure FlashArray X NVMe cons

"The physical architecture could use some higher levels of redundancy."

"I believe having more replication options comparatively to VMAX (other than RecoverPoint) would be great."

"XtremIO needs to be lower priced. It also needs better endpoints and scalability."

"In the next release, the solution could have better integration and if we can host assets on the cloud, such as NetApp has the NetApp volumes, which we can host on the cloud directly called NetApp CVO (cloud volume ONTAP). Dell EMC should come up with something purely on the cloud rather than manage services."

"XtremIO is coming to its end of life."

"Scalability could be better."

"The GUI could be modified more in terms of how the different components are linked to each other."

"One thing that should be improved is the reporting and monitoring tools. It should use real time monitoring for storage, IOPS, latency, etc."

More Dell XtremIO cons

"When you look at the competitors, they have some features available, for example on the deduplication side."

"NetApp could lower the price and offer a true cluster architecture. It's currently a 1.4 cluster, not a real 2.0 cluster."

"I would like it to be an IP as our network is mainly IP-based."

"The price of NVMe storage is very expensive."

"I think for us, improvement would probably be the changes in how the flash is actually used inside the system and how we manage the actual disk and stripes within the system."

"The admin tools and the integration with other products and clouds can be improved. It should also be easier to identify and troubleshoot problems in this solution. It takes a long time, and it should be improved."

"A while ago, they performed quite slowly."

"NetApp's price could be improved. All storage is expensive. NetApp is not cheap, but we can't return to anybody else now. We'd lose too much value. We'd be, reinventing ourselves."

More NetApp AFF cons

Pricing and Cost Advice

"We pay approximately $50,000 USD per year in licensing fees."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"As far as the licensing costs, everything is included in the license."

"Given its price, Pure is not the first option."

"The licensing is on a yearly basis."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"With VMware, we pay $300,000 annually."

"The support cost per array is about $20,000 a year for 24/7 support."

More Pure FlashArray X NVMe pricing and cost advice

"You can get a two-year or three-year license for the tool. You can also opt for a perpetual-based licensing model, which can be renewed on a yearly or two-year basis."

"XtremIO is an all-flash array, which means it's a costly solution. When compared with general mid-range storage solutions, this is more expensive. As far as I know, there are no additional costs besides the license."

"The license for XtremIO is in the box, so you don't have to buy anything."

"Don’t buy this array. You’re paying for loads of magic beans, since it’s mediocre at best for a platform in a rapidly growing field. Look instead at Pure Storage or something with variable block deduplication. You’ll end up spending less and getting a better product with actual support."

"It is expensive if you need to increase scalability."

"XtremIO is pretty straightforward about pricing. However, you need to look at your data so you can estimate, with the advice of DEL EMC, what data reduction ratio you will reach. In our case, a 3:1 reduction ration gave us a positive case compared to other storage arrays."

"With some workloads that benefit from compression and deduplication, costs are actually better than some tier 2 subsystems (while latency remains <1ms)."

"Licensing is approximately $200,000 per year."

More Dell XtremIO pricing and cost advice

"We don't like the cost. We would like to buy more."

"ATTO bridges add to the total cost of the system."

"If you go for Replication, Vault, and NAS, please ensure that the license has been ordered at the very beginning. However, licenses can been added or modified without rebooting the system at any time."

"Comparing this solution to others it may seem expensive, but the price to performance for NetApp is greater."

"The stability of AFF alone has been a significant ROI."

"It depends on how you look at things, but they are in a higher price range."

"Obviously depending on the price point, NetApp is obviously a little more expensive than your generic Dell SAN solution or whatever."

"One of the reasons we like this solution is that all of the features are included with the one license."

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.”
