Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

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

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

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

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"I appreciate the performance."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

More Pure FlashArray X NVMe pros

"XtremIO’s capability to run any workload without much in the way of design considerations makes this very easy to use and size."

"The Metro clustering and solid-state performance, are the most valuable features of this solution."

"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."

"The most valuable feature of Dell EMC XtremIO is the data protection (DP) group, it is one of the most advanced features in these types of arrays. The dedupe and compression that this array provides both do a superb job."

"I like the deduplication and auto-tiering features."

"XtremIO is very stable."

"We've seen great enhancements from the performance point of view. There's good availability, stability, and continuity, but the performance actually has increased by 60 or 70%."

"The most valuable features include the easy manageability of snapshots and its excellent performance in large-scale workloads."

More Dell XtremIO pros

"The solution has made our lives easier by providing many different storage efficient features and data protection features."

"I've combined other NetApp systems into one of our newer platforms, taking other file-sharing solutions native to Windows or Mac and creating file shares, yielding a better return on our investment. At the same time, we are providing better resources and more efficient channels for files."

"I think that the DR applications are the most valuable, including Snapshots and SnapMirror."

"It is easy to manage data through the GUI by using Active IQ and the unified manager."

"Data efficiency is the most valuable feature because of the dedupe and compression."

"The tool's most valuable feature is efficiency."

"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."

"In terms of the footprint, it is far more efficient. It has smaller, higher-capacity drives than our older unit. In terms of space, power, and cooling, it has simplified things."

More NetApp AFF pros

Cons

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

"In terms of what needs improvement, the dashboard and management could be simplified."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

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

"The UI for this solution needs to be improved."

"Adding some functions to the product would be beneficial."

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

More Pure FlashArray X NVMe cons

"Native data replication: To replicate data between XtremIO devices, you need to use EMC’s RecoverPoint appliances to move the data."

"I am not too impressed with XtremeIO because we had a major failure."

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

"The interface could be simplified for beginners to ease the configuration of special objects in the system."

"In some cases where we don’t need the flexibility of the virtualization layer, we could free up resources on the VPLEX by using the storage replication."

"We've encountered challenges in integrating other products with Dell Xtremio, as it tends to be more vendor-locked. This means we can't easily explore other solutions that might work alongside Dell."

"Sometimes we don't get an immediate response from the support team. The initial POC also took a lot of resources."

"Dell's technical support could be better."

More Dell XtremIO cons

"I honestly don't have anything of note on how they can improve."

"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."

"We have been seeing some challenges around the application layer implementation. We are having some teething problems now with the cooperation between the application layer and backups to things, like SnapCenter. This may be a question of product maturity."

"I would like to see if they could move the virtual storage machines. They have integrated a DR, so you can back to your DR, but there's no automated way to failover and failback. It's all manual. I'd like to see it all automated."

"They should provide easier integration with multiple systems."

"NetApp should offer more training so everyone can learn about the products. Other vendors have a lot of training options. It would be great if NetApp would highlight how to use the features more so that every admin or person can gain more knowledge about this technology."

"We don't have it in production yet."

"When new ONTAP cloud versions come out, they need to have fewer bugs."

More NetApp AFF cons

Pricing and Cost Advice

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

"Our licensing fees are $500,000+ USD."

"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."

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

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"The licensing is on a yearly basis."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"It is costly but worth it."

"The licensing cost is on a yearly subscription basis, which can be expensive but is necessary for ongoing support and services. The pricing could be improved to make it more accessible."

"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."

"The initial purchase price was good but when you need to upgrade, it's a different story."

"Pricing and licensing are in line with other products from other manufacturers. You get what you pay for."

"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."

More Dell XtremIO pricing and cost advice

"I would like it to be a lot less expensive, but it's been a very good solution for us."

"The solution is moderately priced."

"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."

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

"In addition to simplifying the management across a mix of solutions, AFF simplifies the cost. That was one of the main reasons we purchased AFF."

"We have been able to utilize and leverage equipment which was purchased a decade ago up until this past year. So, we were running disk shells for 13 years and all we were doing was upgrading the filings and controllers, and using the same disk shells. Therefore, we were able to do something where we didn't have to invest that much. Recently, we had to upgrade all our disk shells, but it was a lot less because the technology had changed a lot since those times. It is faster now, and we have SSDs. We have larger drives that are 4TBs and 6TBs. Everything can condense so we are saving disk shell space and rack space. We are paying less now than we did at that time"

"There is room for improvement when it comes to the cost. The cost is very high compared to other devices."

"NetApps offers a lot of different options. Just take your time and work with the consulting teams. Lay out what your needs are to ensure you are purchasing what will help you be successful."

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.”
