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.

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."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"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's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

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

"Everything, especially the VMs inside, is pretty fast."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

More Pure FlashArray X NVMe pros

"The solution allows for easy, useful replication with good features for VPLEX and VIVO."

"It will certainly help us scale bigger. If I look at the footprint, the VNX's was multi-rack. Now, all of a sudden, we're only at a portion of a rack. And, obviously, if we can scale within the same rack - we can certainly see that by the number of hard drives we've had to put in - we can scale a lot more easily."

"It has the same operating system for both file and block, and it actually simplifies everything. And it's much smaller compared to VNX."

"The most valuable feature is the dynamic cache of this product. It is very important. We have the physical cache and we can boost this cache using disks. All the products are mainly flash now and this is one of the main characteristics which our customers like."

"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 Snapshot feature is key."

"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."

"The Unisphere management interface: We are very familiar with it. It manages all the EMC devices that we have. Management is easy because it is part of Unisphere, which is self-learning."

More Dell Unity XT pros

"It provides multi-protocol, which is what gives the edge when it comes to big lineage PC workloads."

"Compared to Dell Unity XT, what I see as an advantage in NetApp EF-Series All Flash Arrays is the fact that it is more scalable...The performance of the product is good."

"The initial setup is pretty straightforward."

"I would have to say performance at this point, because the application it is based on is so diverse."

"The solution allows us to segregate one storage unit from another."

"This storage solution is both stable and scalable, and it works for our needs."

"Rapid deployment, easy integration management and cloning of areas."

"Considering the cost, I find NetApp EF-Series All Flash Arrays to be the best storage available in the market."

More NetApp EF-Series All Flash Arrays pros

Cons

"There is room for improvement in the pricing of the product."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"The tool's pricing is higher than competitors."

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

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

"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."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

More Pure FlashArray X NVMe cons

"The one thing that we would look at would be if they were to expand the file level features, just to give us a balance or a tier between it and Isilon options out there, for unstructured data."

"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."

"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."

"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."

"There is room for improvement in manufacturing."

"Scalability for the 650F is good, but I was expecting a little bit more."

"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."

"I miss storage groups. Now, if I have to add a LUN to a cluster, multiple host, I have to know which host is in that cluster. I have to write it down and that makes it hard. In VNX and earlier, I could simply put a LUN on a storage group and every host in the group had the LUN. This lack bothers me a lot because it takes a lot of time and mistakes are made. Sometimes, a Hyper-V host gets a VMware LUN and vice-versa. Not good."

More Dell Unity XT cons

"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."

"There could be an improvement when it comes to SLA support, it could be faster."

"It needs a better management tool."

"The price of the All Flash solution is very high."

"The dashboard could be simplified."

"They could improve overall scalability through performance. Denser capacity, which is doable, it is what the competition is doing."

"As far as the manageability, being able to port between the two and have to do less training in-house from a customer point of view, that would be the part to improve."

"It was difficult to implement and lacks some additional features that would be useful, but as a solution fits a particular need for our organization."

Pricing and Cost Advice

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"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."

"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 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."

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

"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."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."

"It is a good return on investment."

"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."

"We have to apply for a license for each system."

"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"

"Compression is making a difference towards the amount of hardware that we need to purchase."

"There is not a license required for the use of the solution. We purchased a maintenance contract."

"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."

More Dell Unity XT pricing and cost advice

"It's a way to get relatively low-cost, very high-performance, low-latency block storage as a point solution."

"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."

"Price-wise, NetApp EF-Series All Flash Arrays is costlier than Dell. You have to buy a lot of licenses separately."

"The pricing of this solution is competitive with other vendors here in Egypt."

"Most of my customers pay for the license on a yearly basis. It can be expensive depending on the capacity number."

"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."

"The pricing is comparable with other competitors and similar in mid-range solutions, and for high range solutions, it would depend on our requirements or needs."

"They provide licenses upon purchase, so there's no need for additional licenses. Regarding additional expenses apart from the standard licensing fees, such as for support or maintenance, there aren't any. Updates take around twenty to thirty minutes, including rebooting the systems, and we haven't faced any problems with the NetApp EF-Series All Flash Arrays. We utilize various other storages like Fujitsu, IBM, and Dalian SIP, but the NetApp EF-Series stands out as we've had no issues throughout the entire year of usage."

Reviews from Real Users

Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

A Systems Engineering Manager at a manufacturing company says, "It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
