Helps to save money and resources with the data compression feature
One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

Has a fantastic feature-set and works well with workflow solutions
I would suggest, if you heavily depend on the Oracle solution from the database you should consider Oracle All-Flash because, from my understanding, it is from a single OEM, it's a single solution. It would be a homogeneous environment. I think it would be definitely a better option for customers considering other all-flash storages. It would be better if you consider a solution from Oracle, from the database studio, the storage part. I would rate it an eight out of ten. To make it a perfect ten, in the next release, I would like for it to be NVMe compliant storage.

Quotes from Members

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

Pros

"The most valuable feature of this solution is its ease of use."
"Everything, especially the VMs inside, is pretty fast."
"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 tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."
"The database workloads are pretty fast because I frequently move data from here to there."
"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."
"It has good, reliable, fast storage."
"Overall stability is very good. It is a very stable solution."
"Dell Unity XT is a unified box, and it is integrated with VVOL, our software-defined storage."
"The product has helpful local technical support."
"I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"It can be simple to deploy, the standup time is quite quick. The interface is quite quick. The terms are simple, intuitive, it's similar what was there in the VNXE before it. It's very simple to navigate and administer from the console."
"We have integrated it with vSphere and SQL. There were no costs involved outside of our normal workload licensing, no costs that were specific to the Unity platform."
"The most valuable feature of Dell Unity XT is its support of protocols for both block, and file levels. It has the features a store solution should have."
"It is a stable solution that sells a lot...The deployment phase of the product was very easy."
"It's actually shaking hands with the workflow solutions much better than any other storage."
 

Cons

"In the next release, I would like to see real-time analytics for further insight into consumption models."
"It is on the expensive side."
"In the future, I would like to see integration with enterprise backup systems."
"We need better data deduplication."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"There is room for improvement in the pricing of the product."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"The tool's pricing is higher than competitors."
"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."
"If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to enhanced."
"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."
"Dell Unity XT could add a unit-to-unit replication. We haven't seen that because we don't have an additional one to test. However, it is not an improvement, but something that we would like to have visibility on how it's done or how it works."
"Compression and block deduplication on non-all-flash solutions."
"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup. This would help us minimize our IT cost in terms of the backup procedures."
"The only challenge I've ever had was with a Drive firmware upgrade."
"The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult. They should improve this to have a better reporting system."
"It has to be flexible according to the customer's requirements. It has to be aligned with the customer business and the business environment."
 

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."
"Our licensing fees are $500,000+ USD."
"We pay approximately $50,000 USD per year in licensing fees."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."
"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."
"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."
"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 price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"Looking at it based on cost per gigabyte, it's certainly very effective."
"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."
"I liked the price point when we purchased it."
"It is an average priced solution."
"The solution is very expensive."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"The solution is very expensive."
