Featured Reviews

Eugene Hemphill - PeerSpot reviewer
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.
Brian Ricci - PeerSpot reviewer
It's constantly enhanced and has impressive reliability and data compression
The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal. I hope Dell addresses that. Everything is pricey these days anyway. It is not like the old days of Compellent. We used to be able to see the metrics for our customers. On Compellent, we could look up that customer and see all the metrics. That is not allowed for us now. We cannot do that anymore. I have to be explicitly allowed by the customer to do that, and some companies' security does not allow that.
Anna Sofo - PeerSpot reviewer
Since switching, our clients have reported improved performance and reduced latency
I like NetApp AFF's deduplication. The solution's AutoSupport feature is efficient and effective because customers are notified of potential issues before they experience problems with NetApp. The support is sold based on metro clusters, so they guarantee the client's business continuity. NetApp has an Active IQ app that allows you to get information on your smartphone.

Quotes from Members

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

Pros

"Everything, especially the VMs inside, is pretty fast."
"The solution is scalable."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The latency is good."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"The database workloads are pretty fast because I frequently move data from here to there."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"The biggest improvement we found when moving into Dell PowerStore was the deduplication and compression."
"Has a great mapping feature."
"It provides a big benefit when upgrading a new VMware environment. For example, in a big environment with 10 to 30 ESXs, you can take everything and put that into PowerStore. So, it is cost-effective, which is very important and has been massive for us. You reduce almost 80% from the hardware and work directly from PowerStore. Building hardware, especially in a big VMware environment, is a big issue for my organization."
"There is no complicated configuration for queries and calls. You just create a model and go."
"PowerStore is easy to use. All the drives use soft encryption. To upgrade it, you download the app, and it runs by itself. It's very easy to deploy, share, and create volumes."
"The most valuable features are the three-to-one data reduction and the ability to scale out and up."
"The tool's most valuable features are compression and speed."
"The product's initial deployment phase has been straightforward."
"I think it is a very stable product."
"Having it separate and having a dedicated storage area network or a dedicated network attached storage, for us, just worked better. It's been faster."
"The most valuable feature of AFF is that it offers better visibility and control over performance, ensuring it meets customer needs effectively."
"Regarding features, SnapMirror is one we depend on right now. It helps us provide snapshots to the customers on request. There are many scenarios in which we might take snapshots in various daily use cases. We trigger the snapshots, which gives us a sense of security because we know we have this technology in place if something happens."
"Setting up storage for an application (storage provisioning) is quick and easy. Maybe a quarter of the time is now spent getting the application up and running, or even less."
"If the data is deduplicated, we'll hopefully begin to save space."
"NetApp has sped up delivery for our virtual environment. It's been a great solution. Our customers have been amazed and overjoyed with the performance of our virtual environment, which uses VDI for virtual desktops and VMware for our virtual host servers. Everything is working seamlessly."
"My favorite part is all-flash solid drives. All of my applications are running on an all-flash array. Before, we used to get too many severity tickets on performance, but as soon as we migrated everything to an all-flash array, our critical applications are at top performance."
 

Cons

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"Adding some functions to the product would be beneficial."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"I would like to see replication and DR features in the next release of this solution."
"The UI for this solution needs to be improved."
"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."
"We are happy with the service in general. The only thing would be the price of the platform."
"Dell PowerStore should offer more cybersecurity and warehouse data security."
"The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal."
"Dell PowerStore is too expensive, and it could be less complicated. It isn't as user-friendly as other options, especially regarding the user interface."
"Users can be enrolled in lifecycle extension with pro support. The pricing for that is too high for PowerStore."
"The cost of technical support is high."
"The only area I can highlight for improvement is that the 4:1 data reduction target has not been reached. This may be due to an issue with Dell EMC's initial analysis of data compression. As a result, we have had to add new physical disks to reach our goal of total available disk space."
"It was very new when we first deployed it a year ago. Even the upgrade processes and knowing what to expect, as well as documentation, could be more robust."
"The procurement process could be improved. It takes a long time for us to receive stuff. The product is good. It's not the product, it's just that it takes forever to get it. It's not our reseller's problem; it's usually held up at NetApp."
"The product should be more competitive and come up with additional features. They should keep the client always in mind and as the top priority. This would be the best way to compete with other solutions."
"The cost of this solution should be reduced."
"Cleaning up false positives on alerts. We get a lot of those."
"I would like to see a little more flexibility in customizing some of the SnapMirror stuff. We have been having a little trouble and, in the first round with tech support, they say, "Well, this is how we do it." It's not exactly throttled but it's limited in the number of connections it makes. We would like to be able to tweak that, to increase it a little bit, because we don't have half a dozen large areas that we are protecting, we have more like 40 or 50 areas. They run into each other a little bit and I don't want to spend time on them."
"It would be nice to have better integration between SRM and VMware, as I've had some issues with that."
"Going forward, I would like more performance analytics on it, on the area itself, instead of using some other tool."
"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."
 

Pricing and Cost Advice

"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."
"We pay approximately $50,000 USD per year in licensing fees."
"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."
"With VMware, we pay $300,000 annually."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The support cost per array is about $20,000 a year for 24/7 support."
"As far as the licensing costs, everything is included in the license."
"Given its price, Pure is not the first option."
"The pricing is good. There's no need to pay for a license; it's all-inclusive."
"In terms of licensing, my organization has Dell Technologies End User License Agreement (EULA), but I don't know exactly how it works, though it is a big bundle of licenses for Dell Data Domain, Dell EMC Unity XT, Dell PowerStore, Dell ECS, and all such kinds of storage arrays."
"Dell PowerStore has been priced aggressively, especially when compared to other NVMe storage options. It is likely one of the most cost-effective options for organizations seeking a pure NVMe play in terms of pricing."
"PowerStore's pricing is reasonable."
"It is very expensive though when you get to this point of using the 3000 with a client. They will start to think about using another vendor. There are a lot of solutions similar to PowerStore in regards to networking capacity and their prices are very cheap compared to PowerStore."
"The solution is expensive."
"We are currently using Dell PowerStore for our smaller storage and there is no competition for pricing."
"The pricing structure and licensing model of Dell PowerStore are very good and I like it. We chose it because it was reasonably priced and met our requirements"
"I find the pricing to be reasonable, particularly with the recent inclusion of features like snap locking and ransomware protection within the ONTAP license instead of having them as separate licenses."
"Always consider whether you can afford the solution."
"The total cost, the pricing of it, has gone up quite a bit."
"Once we did get into the NetApp ecosystem, we realized that the cost effectiveness was greater than we originally thought."
"The total cost of ownership has decreased a great deal. As far as percentages, it's hard to gauge, but we did have quite a few personnel staying up, making sure batches ran well every night. Now, batches are being done by 8:00 in the evening, so we don't have to do that anymore. When you start adding the employee hours that we have for people working in the off-hours, and it is not an issue anymore, I suspect TCO might have gone down 25 percent."
"The entry point for potential customers, who are looking at coming onboard for flash systems, it may be a bit expensive. It would be good if the price comes down."
"It's expensive but we think over time all the prices are going to go down."
"The pricing is competitive when we compare it to other products."

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…
