We performed a comparison between Dell Unity XT and HPE Alletra based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."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."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"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 most valuable features of this solution are its ease of use and performance."
"It has good, reliable, fast storage."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"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 has benefited my organization because it has reduced time to insights."
"It has reduced complexity."
"The most valuable thing for our use case is the flexibility to have multiple-protocol support."
"I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid."
"I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it."
"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."
"It is completely reliable. The plugins for it are quite mature. I don't really have any issues with the interactions with vSphere, they all work as intended."
"On the Data Domain side, the most attractive feature is the compression ratio, which none of the other products in the market are currently able to provide. On the Unity side, what customers mostly like is the availability guarantee."
"Stable flash storage platform with good scalability, efficiency, and speed."
"The tool's notable feature is that we don't need to log a case directly with the vendor. The tool has access to all the logs on-premises. This is an on-premises solution. Additionally, we can provision data as thick or thin provisioned. Moreover, it includes data grid duplication and compression features."
"It offers rich features and high speed for transferring data."
"In the future, I would like to see integration with enterprise backup systems."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"The software layer has to improve."
"They could add more support for file storage and different types of storage."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"We need better data deduplication."
"The UI for this solution needs to be improved."
"It is on the expensive side."
"This solution could be improved by offering containerization. This is something many of my customers are looking for."
"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."
"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."
"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."
"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"This solution would be improved with the addition of flexible raid volumes."
"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."
"On the data domains - for the Unity product, but specifically for data domain - I would like a much easier interface for managing, for actually going in and having one place where I could get all of the different parts of the overall unit. And I would also like to be able to identify individual disks a lot more easily."
"It would be better if there were an option to incorporate the NVMe feature alongside other storage tiers. Currently, the system operates on Autotier but can manually peer and mix different types of drives, such as SAS and SATA drives."
"We had some issues while installing it on our servers. It required more resources while cross-checking. So, the initial setup process could be better."
