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.

Head of Infrastructure Security (S.A.V.P) at EXIM Bank Ltd

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.

Technical Head with 51-200 employees

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 solution uses newer technology for deduplication and compression."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"The most valuable feature of this solution is its ease of use."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"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."

"One of the best features is the support, which is excellent."

"Everything, especially the VMs inside, is pretty fast."

"I appreciate the performance."

More Pure FlashArray X NVMe pros

"We use replication for disaster recovery (DR), making our DR process much easier."

"I like the idea that it can compress and dedupe inline. That is quite a stunning feature for mid-range customers."

"The ease of management and “user-friendly” management environment (GUI)."

"It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it."

"It has the same operating system for both file and block, and it actually simplifies everything. And it's much smaller compared to VNX."

"It has good performance."

"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"

"Because I always need to trouble shooting for IOPS & database (DB) performance issues. I can quickly focus on what is part of the issue. I can decrease downtime and can plan next year's extended capacity budget."

More Dell Unity XT pros

"It's actually shaking hands with the workflow solutions much better than any other storage."

Cons

"I'd like to see the product implement active replication for vehicles such as VMware."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"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."

"The UI for this solution needs to be improved."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"There is room for improvement in the pricing of the product."

More Pure FlashArray X NVMe cons

"The price of this product can be more cost-effective."

"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."

"Software updates have to be downloaded to the root of the device. This pushes the available space to 95% utilization."

"This solution could be improved by offering containerization. This is something many of my customers are looking for."

"A customer had to buy VMX because Unity didn't have WORM."

"The pricing is a bit higher than expected, and this is an area where I see room for improvement."

"There is room for improvement in manufacturing."

"This solution would be improved with the addition of flexible raid volumes."

More Dell Unity XT cons

"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

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"As far as the licensing costs, everything is included in the license."

"With VMware, we pay $300,000 annually."

"The product is expensive."

"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."

"We pay approximately $50,000 USD per year in licensing fees."

"The licensing is on a yearly basis."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

More Pure FlashArray X NVMe pricing and cost advice

"Most licenses for the solution are free but upgrades are available when adding additional software or storage."

"The solution should be cheaper."

"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."

"The price is good for commercial grade storage arrays."

"While Dell EMC is costly, I don't have any complaints about their licensing model."

"With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity."

"We purchased a five-year warranty."

"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."

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."

Dell Technologies
