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.

Customer needs are addressed effectively with collaborative sales and service support

Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature. NetApp's FSA model 2750 comes with an inbuilt cloud tiering option. In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.

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 tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"What I really like about this program, is that it is easy to use and easy to configurate."

"Technical support has been helpful and responsive."

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

"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 high availability of the product is the most valuable feature."

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

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

More Pure FlashArray X NVMe pros

"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."

"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."

"You can add volume and it's automatically registered in VMware."

"I like that when you log in it gives you a dashboard of what your storage looks like."

"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."

"The inline deduplication and data reduction capabilities have been the most valuable."

"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."

"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."

More Dell Unity XT pros

"We use it for our VDI environment, and have not had any complaints with it."

"Some of the valuable features include MetroCluster switchover, in terms of disaster recovery, it is easy to use, and flexible."

"The benefits are better up-time, better response time."

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

"The speed is the most valuable feature."

"The product's initial setup phase can be managed easily and completed in 20 to 30 minutes. It is one of the fastest storage tools that you can implement."

"The most valuable feature is the ability to set a specific margin of performance to a specific workload."

"Its performance is most valuable. This solution is much faster than other as well as older storage solutions. The performance of the system is very good. We are getting 50 times better experience than the older storages. We are using AFF 300. It also has native cloud integration and most of the features."

More NetApp EF-Series All Flash Arrays pros

Cons

"The tool's portfolio is minimal. It is expensive."

"We need better data deduplication."

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

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"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."

"I would like to see replication and DR features in the next release of this solution."

"There are some challenges with data encryption and reduction."

"Maybe the price can be reduced since the solution is very expensive."

More Pure FlashArray X NVMe cons

"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."

"The product’s pricing should be improved."

"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."

"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."

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

"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."

"It would be great if the solution could integrate an NVMe disk."

"We integrated it with vSphere but that integration was "iffy". It was okay but we had a few challenges with it."

More Dell Unity XT cons

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

"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."

"It needs a better management tool."

"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."

"We have used IBM previously. We found that the storage from IBM was poor and we chose NetApp EF-Series All Flash Arrays because it can scale very easily."

"NetApp could improve the speed of the rebuilding rate."

"I would like to have the ability to replicate data between All Flash and other NetApp storage systems."

"The pricing could be cheaper and it should have documentation in more languages, specifically, Russian."

Pricing and Cost Advice

"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."

"With VMware, we pay $300,000 annually."

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

"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."

"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."

"We pay approximately $50,000 USD per year in licensing fees."

"The product is expensive."

"The licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

"The solution’s pricing is competitive."

"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."

"This product is cheaper than the EMC VNX solution. It is good for small businesses."

"It is an average priced solution."

"Most licenses for the solution are free but upgrades are available when adding additional software or storage."

"This solution offers great pricing."

"The solution is extremely functional for the price that we pay for it. It is worth the investment."

"It is shipped with all licensed, included for this product range, no need to buy additional licenses"

More Dell Unity XT pricing and cost advice

"This solution is not available to many users because the cost is very expensive."

"NetApp EF-Series All Flash Arrays is an expensive product."

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

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

"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."

"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."

"It's a lot cheaper than what the other vendors have for the same type of environment. It saves us money."

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."
