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.

Customer support excels with quick escalations and problem-solving capabilities

NetApp AFF A-Series is faster and more robust compared to the all-flash storage of NetApp. Its deduplication feature is also quite good. Additionally, in terms of support, NetApp has a strong side as their services are more prompt and feature an escalation matrix. The vendor's support is noted for immediate action when issues are escalated.

Quotes from Members

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

Pros

"Technical support has been helpful and responsive."

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

"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."

"After the testing, it was clear to us that the Pure FlashArray X NVMe was the easiest to manage and configure and had the best performance that we had seen in all the arrays."

"Being able to have broken files on-site on the same appliance is quite useful."

"We generally always advise people to make the choice to go with Pure Storage because they won't regret it."

"The most valuable features of this solution are its ease of use and performance."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

More Everpure FlashArray X NVMe pros

"To be programmatically administered is huge, it is one of the key features that we like about it."

"Its most valuable feature is the storage alarm."

"The most valuable feature is the integration with vCenter."

"Their product is stable."

"The hardware is fine, a nine or a 10 out of 10."

"It is completely reliable, the plugins for it are quite mature, and I don't really have any issues with the interactions with vSphere, they all work as intended."

"It is stable, I have not personally seen any issues when deploying in a customer environment."

"Stability has been pretty rock solid for us."

More Dell Unity XT pros

"The amazing thing is that whenever we have come up with an issue where we need to get something done, and it wasn't necessarily available, they could do things for us, usually within the next revision of the software."

"NetApp's inline deduplication and compression are unmatched compared to other vendors."

"NetApp AFF A-Series is faster and more robust compared to the all-flash storage of NetApp."

"MetroCluster is the best product on the market. It synchronizes the storage. NetApp's update packages are a huge advantage because the firmware and server updates are in one package."

"We've reduced downtime. Without all of NetApp's benefits, we would have had to reconfigure parts of storage that would have required downtime. We have dramatically reduced our downtime through successive generations of NetApp, allowing us to get Five 9s availability."

"The deduplication and compression options from NetApp AFF A-Series are good to use for efficient storage capacity."

"NetApp support is fantastic."

"NetApp's hot and cold storage are its most valuable features. We currently use the A series. Immutable snapshots are another advanced security feature that is positive."

More NetApp AFF A-Series pros

Cons

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

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

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

"We have run into a couple of instances recently where we are running out of space."

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

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

More Everpure FlashArray X NVMe cons

"If the product could only send alert notification via SMS, it would be much better."

"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."

"Yes, sometimes the DNS does not work out properly."

"Recently, they released products, sometimes without proper testing, it seems."

"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."

"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."

"We do a lot of VMware. It only integrates with VMware in one way, which is virtual volumes."

"The ease of installation, sometimes, for the customers, is not that positive because the customers think they can do it themselves."

More Dell Unity XT cons

"NetApp AFF A-Series should work on cost. The solutions, especially enterprise-level storage, should be more affordable to improve their appeal to businesses."

"It would be helpful if our partner organized a yearly session with my team to discuss the new feature sets on our current solutions and other ways NetApp can help us. Perhaps we are missing some information to help us make the right decision."

"NetApp is shifting to the cloud and adopting AI, but it is not improving its core technology to deliver faster storage. We're still waiting to see if it improves speed with solutions like the 90 series."

"The solution's ransomware protection could be improved."

"Pricing could always be lower."

"I really don't have a lot of complaints. In the past, there were issues, however, they've really done a great job of reaching out."

"We have several problems with the limitations of NetApp systems in terms of volume shares. We have a brick in a 700 or a controller, and we sometimes make small volumes, but Kubernetes container volumes don't allow us."

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."

"The support cost per array is about $20,000 a year for 24/7 support."

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

"The product is expensive."

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

"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."

"Given its price, Pure is not the first option."

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

More Everpure FlashArray X NVMe pricing and cost advice

"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."

"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud. They have to protect their market by giving commercial or financial incentives."

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

"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."

"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."

"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."

"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."

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.”
