Jaehoon Oh - PeerSpot reviewer
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.
Stanislaw Jagielski - PeerSpot reviewer
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.

Offers seamless installation and efficient data handling with robust support
NetApp AFF provides an all-flash storage solution for unified SAN solutions, supporting both SAN and NAS functionalities. Data reduction capabilities such as deduplication, compression, and compaction are standard features included with the license in NetApp AFF. With the storage efficiency from a NetApp AFF installation, users can manage substantial data running on all-flash. The features such as compaction and compression provide storage efficiency guarantees in an all-flash environment.

Quotes from Members

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

Pros

"One of the best features is the support, which is excellent."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"It has benefited my organization because it has reduced time to insights."
"The most valuable feature of this solution is reliability."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"It has good, reliable, fast storage."
"The most valuable feature of this solution is its ease of use."
"It is great for applications like Microsoft Exchange, ERP, SQL and VDI; basically saved the VDI buy-in from users, as now performance was seamless in comparison to a physical PC."
"Deduplication and cloning capability"
"The most valuable feature of the solution is its performance."
"Very good IOPS performance"
"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."
"The program is very stable."
"I like the deduplication and auto-tiering features."
"I rate Dell XtremIO at eight out of ten. It is a product I would recommend to companies where data performance, scalability, and security are highly important due to its beneficial features."
"The most valuable features are the flexibility and level of technical support."
"The NetApp technology that has delivered the most value to our organization is FabricPool."
"We reduced our floor space by reducing 44 racks units to four rack units. It has helped us with our data center economies of scale. It reduces our support costs too, which is great."
"The speed is important; no more problems caused by high latency."
"The NVMe flash cache is the most useful feature. It lowers transactional speed even more."
"It's pretty scalable. It can scale up to 24 nodes."
"It is easy to manage data through the GUI by using Active IQ and the unified manager."
"The most valuable features are the IO performance that we get, the cluster part, and the increased workload and performance with the SSDs."
 

Cons

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"There are some challenges with data encryption and reduction."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The tool's pricing is higher than competitors."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"Right now, external appliances are needed to replicate XtremIO to XtremIO, or to another EMC system."
"The solution's stability has certain shortcomings where improvements are needed."
"I would like to see more scalability."
"The product is highly expensive."
"The physical architecture could use some higher levels of redundancy."
"It is very expensive to scale. You have to buy an additional system to extend from one disc, for instance. It is scalable, but extremely expensive to do so."
"Scalability is something that can be improved because there is an issue when it comes to mixing versions."
"The product is highly expensive. Additionally, there is a significant lack of training, support documents, and forums available for Dell XtremIO, making troubleshooting difficult for third-party individuals."
"The knowledge base could be improved."
"We were migrating from Data ONTAP 7-Mode to its Cluster-Mode. Therefore, we had to get swing gear, then do the migration from loner gear and back onto our new gear. This was a bit difficult. It took us several months to do multiple migrations."
"We'd like to see data move faster."
"In the current atmosphere, private cloud is improving. NetApp AFF needs to provide flexibility in terms of hardware and capital expense."
"The initial setup has a lot more steps in it than are probably necessary for a base deployment, unlike other vendors where it's more straightforward. It could be a little bit more streamlined."
"I would like to see aggregate level encryption in the next release. This is critical."
"Additional performance, additional data efficiencies, that's what everybody wants right now."
"The cost of this solution should be reduced."
 

Pricing and Cost Advice

"Our licensing fees are $500,000+ USD."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The product is expensive."
"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."
"As far as the licensing costs, everything is included in the license."
"The licensing is on a yearly basis."
"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."
"Given its price, Pure is not the first option."
"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."
"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."
"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."
"The license for XtremIO is in the box, so you don't have to buy anything."
"This is the best flash array on the market for high-end workloads, so expect to pay for that. But the support subscription cost is fixed for seven years, which made it easier for us to plan on the maintenance costs."
"There are costs in addition to the standard licensing fees."
"The initial purchase price was good but when you need to upgrade, it's a different story."
"It is expensive if you need to increase scalability."
"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."
"It depends on how you look at things, but they are in a higher price range."
"NetApp is getting too expensive."
"It is relatively cheap compared to other vendors."
"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."
"Using NetApp, our total cost of ownership decreased by 17%."
"Always consider whether you can afford the solution."
"Planning of all the lifecycle storage with NetApp AFF is part of the solution. While it is not cheap, they have introduced a new series of AFF that are more affordable, providing options for more users."

NetApp vs. XtremIO
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…
