We performed a comparison between Dell Unity XT and Pure FlashArray X NVMe based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."It is fast and reliable. It works."
"This solution has improved our organization. In the past, we had reports that were taking up to two hours and after switching to SSD storage the overall processing power dropped to half an hour. The end users saw an immediate performance gain."
"Pure Storage is extremely reliable — it's never failed."
"The most valuable feature is its upgradeability."
"The predictive performance analytics are good."
"The management features are well organized and they have a very good dashboard."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"The initial setup was straightforward in the way that it was a database vacuum storage."
"It is scalable. We can add additional tools if we need to expand it."
"It's an all-flash Unity, With that compression feature, it's comparable to a hybrid. That is one thing that we definitely like."
"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."
"I like that when you log in it gives you a dashboard of what your storage looks like."
"The product has helpful local technical support."
"This solution is easy to work with and easy to maintain."
"The most valuable feature is the integration with vCenter."
"We are happy with the way we have Dell EMC Unity XT configured."
"Technical support has been helpful and responsive."
"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."
"The solution is scalable."
"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."
"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."
"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 Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"They could improve the price."
"There are a lot of things to improve."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."
"The price should be lower."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"I would like to see data tiering to AWS."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"Inline dedup compression security is coming up as an issue, encryption, etc. is key for our customers. If we could have more ways to do software-based encryption, those are the features customers are asking us for, as well as replication."
"A customer had to buy VMX because Unity didn't have WORM."
"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."
"This solution could be improved by offering containerization. This is something many of my customers are looking for."
"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"Firmware Upgrades in EMC Unity require you to manually download OS and Drive firmware, this should be integrated (Nimble does this). When you order an EMC Unity, you have to specify the block size. This is weird for me and even weirder that you cannot change this afterwards, you should be able to specify per LUN/datastore (Nimble does this as well)."
"I would like to see replication and DR features in the next release of this solution."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The UI for this solution needs to be improved."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"In fututre releases, some focus on anti-malware should be there."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
