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

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"The most valuable feature of this solution is reliability."

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

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"It has benefited my organization because it has reduced time to insights."

"The solution uses newer technology for deduplication and compression."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

More Pure FlashArray X NVMe pros

"We are happy with the way we have Dell EMC Unity XT configured."

"It is great because it can work as a SAN and net storage."

"The UI itself is fantastic, and the ease of administration is far better than Unisphere or Navisphere ever were. It's very easy to manage. The fact that it has built-in APIs means our automation people can help us automate a lot of tasks, and that has been helpful. And, of course, it's really fast. Obviously, that doesn't hurt anything at all."

"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."

"It is easy to manage. A lot of the system manages itself."

"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example. It depends on you use it, but for our purposes, we find Unity simple to use."

"The product has helpful local technical support."

"It has reduced complexity."

More Dell Unity XT pros

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

Cons

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"The tool's portfolio is minimal. It is expensive."

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

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

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

More Pure FlashArray X NVMe cons

"Things that could be improved include one-to-many replication, data deduplication, and asynchronous Fibre Channel replication. It is asynchronous on iSCSI and I would like to have that on the Fibre Channel. Unisphere-wise, I have to log in to each Unity as a unique environment. In VNX, I logged in to the domain and I was logged in to every VNX. So that's missing."

"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."

"I would like to see more compression and deduplication added to the solution. Today, our compression is about 2:1 and other solutions give us about 4:1 or 5:1."

"Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent."

"The initial setup is not so straightforward if you don't have experience with storage arrays."

"Issues with slow responses from the support team."

"Dell could improve Unity XT by adding support for NVMe."

"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."

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."

"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."

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

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

"Our licensing fees are $500,000+ USD."

"The licensing is on a yearly basis."

"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."

"Given its price, Pure is not the first option."

More Pure FlashArray X NVMe pricing and cost advice

"The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."

"Compression is making a difference towards the amount of hardware that we need to purchase."

"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."

"The solution is very expensive."

"The ROI is right where we need it to be. It's a reasonably priced array."

"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."

"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."

"Our costs are roughly $200,000 a year."

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."
