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.

Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

Offers good performance and
Once, I've been in a program, but they stopped supporting protocols like HTTP, STP, and that kind of stuff. All of the DIP supports at the beginning were kind of support when it was just Python and just five storage. And it happened a few times that the customer required the STP and HTTP protocol for storage. And I was surprised I couldn't do it anymore with NetApp. So, it would be beneficial for them to support both kinds of protocols. The only little black points that I would put on top of NetApp FAS Series. There is room for improvement in deployment and configuration processes. The thing with ONTAP is that we have a lot of layers, from the raw disks to the volumes we present to servers and configure. There are quite a lot of things to configure. Probably NetApp should ease the way to install that. In NetApp products, such as ONTAP and FAS, a solid understanding of storage is still necessary to handle configurations in larger systems. It's not the same with Pure Storage or Huawei. Even someone less familiar with storage could manage it, making it more accessible.

Quotes from Members

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

Pros

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"Technical support has been helpful and responsive."
"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 latency is good."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"It is scalable. Customers are going more into distributed architecture, so the Unity definitely has a scalable architecture built into that."
"For me, the most valuable feature is the ease of management."
"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."
"My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us."
"It is easy to scale, maintain, and manage."
"Initial setup is a simple process."
"We can sleep at night because the support is great."
"The most valuable features are the NAS features and NetApp's excellent support."
"I have found all the features useful in NetApp FAS Series."
"The SnapMirror is a good tool because, as long as you're going NetApp to NetApp, it's ultimately the fastest way to move data. We replicate everything to another site for disaster recovery."
"The product is flexible."
"The most valuable feature of the NetApp FAS Series is the snapshot and the FlexClone for Oracle and Microsoft SQL environments. Additionally, the integration can be done with most all on-premise and cloud providers."
"The replication feature protects us from data loss."
"Saves space with deduplication"
"One important feature for customers is its ease of use and continuity, enabling seamless usage across on-premise and cloud environments."
 

Cons

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"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."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."
"I would like to see better compression, better dedupe. It's not nearly as good as what is built into the XtremIO. I understand why that is the case, but if they can take some of that technology and leverage that a little bit better in the Unity array, that would be great."
"The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM."
"In some countries, spare part availability is an issue for us."
"I think Dell EMC should be more careful in appointing partners, and they need to have better control over their partners. And if their partner has some problems with them, we should not suffer."
"Problems with I/O modules, with bugs that came out that really should have been caught before the product was released."
"There are some features in VNX that I wish were in the Unity. For example, Storage Groups for isolating LANs and hosts. That is a big issue."
"The solution should include a free process in the HPE portal that uses serial numbers to verify that hardware is genuine."
"With scalability, we feel the system is limited."
"The solution’s pricing is expensive."
"I would like to see NetApp add incident support."
"The plan is to go with all SSDs and use MDM, rather than sticking with traditional disk drives. The goal is to have all SSDs for better maintenance speed, which is essential for applications that need to work."
"The solution can improve on the replication features."
"NetApp FAS Series could improve by being more secure."
"We're supposed to have used NetApp FAS Series for replication, but then one of the nodes failed, and then it's taken us some time to bring it up."
"Interfacing with the cloud environment could be better. I want to be able to move some cloud volume and integrate it seamlessly with my home on-premise storage. Sometimes I have issues with port permissions. NetApp probably needs to improve more on the integration side from on-premise to the cloud."
 

Pricing and Cost Advice

"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"The product is expensive."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"With VMware, we pay $300,000 annually."
"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."
"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."
"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."
"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."
"Our costs are roughly $200,000 a year."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"In general, I find NetApp to be very expensive. That's the main issue I have with them. So it's a drawback in terms of pricing."
"The only area that could be improved is to lower prices for their All Flash FAS."
"The pricing of NetApp FAS Series is reasonable for its performance."
"The solution is more expensive than other vendors."
"I've sold arrays for as little $20,000 USD and as high as $300,000 USD."
"The process for going to cluster mode is expensive."
"It is a moderately low-priced platform."
"It’s difficult for us to get money, so make sure you get everything in order, because there’s no going back and saying “oh, I missed this or that”, so make sure you plan well and well in advance."
