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.
Syed Habib - PeerSpot reviewer
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 flexibility and top-notch technology
You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

"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."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"It has benefited my organization because it has reduced time to insights."
"The database workloads are pretty fast because I frequently move data from here to there."
"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."
"Overall stability is very good. It is a very stable solution."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"We particularly like the user interface on cloud IQ with this product."
"It has a very intuitive web console that runs in HTML5 and makes navigation and administration fairly easy."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."
"It has the same operating system for both file and block, and it actually simplifies everything. And it's much smaller compared to VNX."
"They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working not just for replication but for backups as well."
"Snapshots provide a unique feature for testing and make management more comfortable and easy."
"Being all-flash makes everything super-fast. It's also great to manage. That's the easiest part. We also have another SAN, from Pure, and the Unity is easier to manage than the Pure."
"The most valuable feature is the ability to set a specific margin of performance to a specific workload."
"The replication and mirroring features are very good."
"The most valuable feature of this solution is the performance of the database access."
"The benefits are better up-time, better response time."
"Considering the cost, I find NetApp EF-Series All Flash Arrays to be the best storage available in the market."
"Having the option of such high-speed storage in the data center is what makes it valuable."
"The speed is the most valuable feature."
"The NetApp EF-Series gave our organization easy access to our data bases."
 

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."
"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."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"It is on the expensive side."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Adding some functions to the product would be beneficial."
"I haven't seen the roadmap for this solution."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"I would like them to continue to build on the solution and expand on the functionality, like replication."
"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."
"Because we can do synchronous replication between the two sites, this made the setup challenging for this piece. They did not know how to set this up initially. We ended up having to do bidirectional synchronous replication."
"Maybe deduplication would be something that would be better to have. Also, it's a fairly new management interface, so work is still being done on that. But compared to other vendors and previous EMC storage, the Unity is really good."
"Ordering is easy, but the processing site and working with those companies was difficult."
"Issues with slow responses from the support team."
"They could improve overall scalability through performance. Denser capacity, which is doable, it is what the competition is doing."
"This solution has limited storage."
"This solution does not have any compression or deduplication."
"The only major drawback is the replication between EF-Series units."
"Their problems are on the software and the controlling of the storage where they lack segmentation and federation."
"Things like the FlexClones, SnapVault, SnapMirror, all of that. Some of it's available on the EF series, but we like what we have in the FAS system."
"Its pricing should be better. Its price is competitive, but they need to improve the pricing. They have different licensing models, which they need to improve. My expectation was cloud integration, which they have, but it is a different license. Therefore, people cannot enjoy it. If I want to use it, I need to pay extra. There is a cost involved for everything, but it should reach everyone. It is similar to having a Rolls-Royce, but you need to pay extra for the key. If you want the key, you need to pay."
"The solution's technical support is not as good as it is supposed to be since you have to push them to get support."
 

Pricing and Cost Advice

"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."
"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."
"With VMware, we pay $300,000 annually."
"As far as the licensing costs, everything is included in the license."
"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."
"Our licensing fees are $500,000+ USD."
"This solution is a good price for what you get."
"The ROI is right where we need it to be. It's a reasonably priced array."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"The solution is extremely functional for the price that we pay for it. It is worth the investment."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"The license is not required, but we must renew the support every year, every two years."
"Pricing for this product is manageable, though slightly higher than comparable products."
"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."
"They need to improve its pricing. The storage market is dying. So, they need to improve the price because it should reach all people. NetApp is one of the top ones, and they are charging a little bit of royalty as compared to other storage solutions."
"One has to opt for a perpetual-based licensing model for one year or three years. After three years, you need to renew the license."
"It's a way to get relatively low-cost, very high-performance, low-latency block storage as a point solution."
"he price point that we're getting is very competitive in the market. Since we are buying in such a large quantity, they gave us a huge discount."
"The pricing of the solution is expensive, considering the initial investment required...At the end of the product's life cycle, it could get cheaper, but the initial investment in NetApp makes it one of the most expensive solutions."
"Its cost-effectiveness is a major selling point. Compared to other storage vendors, the EF-Series offers excellent value for its price. It's truly a leading product in the industry."
"Adding more capacity will increase the cost."
"Price-wise, NetApp EF-Series All Flash Arrays is costlier than Dell. You have to buy a lot of licenses separately."
