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 high availability of the product is the most valuable feature."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The latency is good."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"It has good, reliable, fast storage."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The most valuable features of this solution are its ease of use and performance."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"It has good performance."
"The most valuable feature is the integration with vCenter."
"I like the ease of configuration, the quick setup and the fact that it seems to be hardened. We haven't had any issues with them. In terms of simplicity of ownership, once they're running you don't have to touch them. They're also simple to manage. We came from the VNXe 3200s so it's very similar."
"The NAS is also extremely easy to set up."
"It is easy to manage. A lot of the system manages itself."
"The most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"They could add more support for file storage and different types of storage."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"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 the next release, I would like to see real-time analytics for further insight into consumption models."
"In terms of what needs improvement, the dashboard and management could be simplified."
"In the future, I would like to see integration with enterprise backup systems."
"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."
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."
"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 only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"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."
"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."
"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."
"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."
