Dell Unity XT and HPE Alletra Storage compete in the modern storage solutions market. Dell Unity XT shows an upper hand in setup and scalability, while HPE Alletra stands out in VMware integration and support.
Features: Dell Unity XT offers unified block and file storage, data-at-rest encryption, and fast cache automation. HPE Alletra Storage provides advanced VMware integration via InfoSight, versatile deployment models, and efficient replication.
Room for Improvement: Dell Unity XT should enhance its deduplication features and offer a more flexible GUI for storage pool creation. HPE Alletra Storage could improve VVaults functionality and ease integration processes, and also add NVMe support.
Ease of Deployment and Customer Service: Dell Unity XT is noted for ease of setup but occasionally experiences customer service delays. HPE Alletra Storage benefits from clear pricing and streamlined customer service, with tools like GreenLake enhancing management.
Pricing and ROI: Dell Unity XT is competitively priced with an all-inclusive licensing model, despite concerns over higher costs than some competitors. HPE Alletra Storage boasts competitive pricing, especially with its GreenLake model, optimizing costs based on usage. Both deliver strong ROI through operational efficiencies.
If you wait more than seven years to buy another one, you get a return on your investment.
For anyone new to the company, it is very easy to understand what is going on, how to manage, how to get access and know what it is doing.
Uptime is ROI.
With Alletra, it downloads the software, and you just hit the button, and go.
Customers always have their issues resolved promptly.
Technical support is good at least through vendors, not directly with the principal.
The support team is familiar with the product and is available on-site during support times, which improves our experience.
Dell solutions are backed by excellent service and support.
The technical support sometimes takes three to four days to get hardware to facilities.
We have four-hour support, and 99% of our issues are resolved within that timeframe.
Last week, a ticket that needed to be solved in six hours took one week.
As soon as we have a problem, we open a ticket with them, and they immediately get back to us well within the four hour SLA that we have with them.
It is highly scalable.
It hasn't broken down anytime in the last six to seven years, despite hurricanes, earthquakes, and power outages.
Dell Unity XT is quite scalable and can be scaled up to the petabyte level.
For NetApp, we can recommend the FAS 8000 series.
We've had zero downtime.
Alletra provides modular, non-disruptive scale-up and scale-out.
If we do grow beyond what the appliance already has, we know that service will take care of it and grow the appliance for us without needing to forklift upgrade.
I would rate the stability of the product at seven out of ten.
I would rate the overall stability of Dell Unity XT an eight out of ten.
The solution is stable and rock-solid.
I have not experienced any downtime, crashes, or performance issues.
I have experienced no issues yet, so I assess the stability and reliability of HPE Alletra Storage as 100%.
We would appreciate a built-in transparent failover in the next release to eliminate the need for a separate metro cluster.
One way to improve the product is to add an operational assistant that doesn't depend on VMware.
I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert.
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.
I believe if Dell can integrate AI to predict potential failures, especially in hardware like hard disks, that would be very useful for proper maintenance.
The pricing is a bit higher than expected.
They shouldn't strip out anything from InfoSight. That is really helpful software to see how the storage arrays are performing and has helped us do a lot of troubleshooting.
They would like to have one tool that can take them everywhere. There should be a single pane of glass.
Most importantly, there is going to be the flexibility of moving compute and storage on Alletra MP.
While the prices may be higher than those of other vendors, we see it as a market leader with benefits.
The support can be a bit pricey, but the solution is more cost-effective than anything else out there.
I would rate the solution as an eight out of ten in terms of costliness.
It is priced at around or under $50,000.
The cost is not cheap nor expensive.
Commercially, Dell Unity XT is viable and competitively priced.
For future use, we bill based on device consumption rather than the traditional datacenter model.
The predictability of having that one-time cost is everything for the data center.
It's expensive.
Its data compression feature is the best that we have ever seen.
The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability.
Pure FlashArray X NVMe helps to improve our processing speed.
Dell Unity XT integration with VMware helps scalability and availability through seamless operations and enhanced performance.
It helps with data cost management and is seen as a mid-range product with good performance.
We installed the Flash, which makes our IO operations fast and efficient.
With NVMe drives, a single drive can provide up to thirty thousand IOPS.
The guarantee of data availability is very important to us. Data runs everything.
The guarantee of data available to our organization is important. We're a manufacturing company. If our systems go down, we lose dollars every minute that system's offline.

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."
