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.

Used for VMs with replication a feature, but need upgraded SSDs

We use this solution. I configured and updated it. Of course, I was also a user of applications that store data on that storage. We already have an SSD solution. So, rather than planning to go with an SSD solution, we are focusing on expanding it. If a company wants to deploy something new, it should choose a product with SSD, and NVMe disks. Overall, I rate the solution a six out of ten.

Quotes from Members

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

Pros

"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."

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

"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."

"I appreciate the performance."

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

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

More Pure FlashArray X NVMe pros

"Veeam Backup integration: Veeam is the defacto standard for backing up of virtual environments."

"Dell Unity XT offers data integration features."

"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."

"The storage management is superb, with a user-friendly graphical interface and dashboards. The performance is good. The integration, dashboards, and analytics are excellent. It gives me immediate output and quick access to the reports I need promptly. It's an excellent product with high stability. The solution is scalable. The support team is highly supportive, responsive, and efficient in providing solutions. This product is highly useful and well-suited for all types of automation."

"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 easy to manage. Managing it, I get alerts if there are any type of issues. I had a hard drive go bad, which had never caused any issues. Dell EMC contacted me, and said, "We are a shipping a new one out." My response was, "Why?" He told me that hard drive was bad. So, I went and looked, and it was. This was almost immediate. I never even knew anything had happened."

"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."

"We just recently started using the Dynamic Pools, so while it's scalable, we actually find it valuable that we can just pop in one or two drives when we need to, instead of having to add a whole RAID set. That has actually been very handy for us."

More Dell Unity XT pros

"The product is flexible."

"Saves space with deduplication"

"Data consolidation and visualization."

"Other products lose performance over time, but NetApp OS is speed-optimized."

"Most valuable features are its ease of use, robust Snapshot functionality, and that you can use it in two datacenters with SnapMirror-ing."

"It's a stable product. No issues there."

"The migration of the volume on the cluster is very useful and easy to use."

"The solution is stable."

More NetApp FAS Series pros

Cons

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"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."

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

"Adding some functions to the product would be beneficial."

"The tool's pricing is higher than competitors."

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

"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."

"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."

More Pure FlashArray X NVMe cons

"There's always room for improvement with the UI. That can be a little cumbersome at times."

"Scalability for the 650F is good, but I was expecting a little bit more."

"The user interface could be improved. The Dell Compellent user interface is fantastic, but the Unity user interface is, in comparison, pretty lousy. It's functional, and I can do what I need, but the Dell Compellent user interface is so much more intuitive and user-friendly."

"I would like better monitoring capabilities: more historical data with more insight into the performance for the database. We now use a separate tool for it. Therefore, it would be nice if we could have that straight from the tool."

"There are features still to come, like compression and deduplication on hybrid platforms, VDM improvements to be developed for NAS environments, and also improvements in the “self-migration” tools to push or pool information (to assist the migrations to and mostly from third-party arrays)."

"One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX."

"I would like to see better compression, better dedupe. It's not nearly as good as what is built into the XtremIO. I understand why that is the case, but if they can take some of that technology and leverage that a little bit better in the Unity array, that would be great."

"I would like to have secure mobile connectivity going forward. This would help me be more proactive."

More Dell Unity XT cons

"A big problem with physical appliances is that updating them can be a bit burdensome."

"One area that needs improvement is the hyper-converged solution. Although NetApp has a solution, compared to Nutanix, it falls short."

"Needs to add wizards for newer, inexperienced users."

"It may need more flexibility to fight with other competing arrays."

"The product should include an audit log feature."

"The NetApp FAS Series is not as high-performing and is not as fast. Its speed needs improvement, but this could only be done if it's an all-flash solution."

"The product should improve its user experience."

"The high cost of the product is an area of concern, so from an improvement perspective, the tool needs to be made cheaper."

More NetApp FAS Series cons

Pricing and Cost Advice

"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."

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

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

"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."

"The support cost per array is about $20,000 a year for 24/7 support."

"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."

"The licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""

"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."

"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."

"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"

"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."

"I rate Dell Unity XT’s pricing a nine out of ten."

"The price is very reasonable."

"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."

More Dell Unity XT pricing and cost advice

"It’s difficult for us to get money, so make sure you get everything in order, because there’s no going back and saying “oh, I missed this or that”, so make sure you plan well and well in advance."

"In general, I find NetApp to be very expensive. That's the main issue I have with them. So it's a drawback in terms of pricing."

"I would rate the pricing a seven out of ten, with ten being expensive. We pay a one-time purchase price."

"If we want a ransomware solution with the product or other extended features, we need to pay an extra cost."

"The solution’s cost is reasonable."

"It is a moderately low-priced platform."

"The solution is more expensive than other vendors."

"it’s not an inexpensive solution and it may not be for the cost-sensitive customer."

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."
