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'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."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

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

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

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

"The most valuable features of this solution are its ease of use and performance."

"What I really like about this program, is that it is easy to use and easy to configurate."

More Pure FlashArray X NVMe pros

"Dell Unity XT offers data integration features."

"I have found Dell EMC Unity XT to be stable."

"I like that when you log in it gives you a dashboard of what your storage looks like."

"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."

"Stable flash storage platform with good scalability, efficiency, and speed."

"The complete block and file sharing are the most usable features."

"On a scale from one to 10, I'd probably give EMC customer support an 11. It's been really good. We do have premium support, which means if we have a problem, it gets solved really quickly."

"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."

More Dell Unity XT pros

"For us, the greatest aspect of the solution is the fact that it just runs. It is amazingly resilient. That's very important to us, because we are basically, with some exceptions, have a 24/7 operation."

"I would definitely recommend NetApp FAS Series to other users because it's stable and really handy for IT personnel who manage it."

"The replication feature protects us from data loss."

"The biggest advantage that makes NetApp FAS Series better is that we can use RAID technology on the storage."

"We can manage our applications from a single dashboard."

"One important feature for customers is its ease of use and continuity, enabling seamless usage across on-premise and cloud environments."

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

"The tool's most valuable features are ease of use, ease of access, expandability, availability, and performance. NVMe drives have improved their performance."

More NetApp FAS Series pros

Cons

"They could add more support for file storage and different types of storage."

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

"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."

"There are some challenges with data encryption and reduction."

"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 have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

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

More Pure FlashArray X NVMe cons

"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)."

"We noticed in the last release of code that there were some inefficiencies around getting our data efficiency up in terms of dedupe and compression."

"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."

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

"We've also encountered an issue when it comes to migrating to compressed LANs on the Unity, and during the Storage vMotion. It appears that the compression algorithm is overwhelmed, and when it becomes overwhelmed it just stops compressing and writes the raw data to the destination. We later copied internally another Storage vMotion to another compressed LAN and achieved much higher compressions on that internal copy. It would be really nice if there was a way to automatically throttle, as a part of a Storage vMotion, to say, "I want to gain the maximum benefits from the compression algorithm, so throttle back the Storage vMotion to implement 100 percent compression.""

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

"It could always use native replication. Then I could get rid of RecoverPoint."

"I haven't seen the roadmap for this solution."

More Dell Unity XT cons

"The solution’s pricing is expensive."

"Interfacing with the cloud environment could be better. I want to be able to move some cloud volume and integrate it seamlessly with my home on-premise storage. Sometimes I have issues with port permissions. NetApp probably needs to improve more on the integration side from on-premise to the cloud."

"We no longer have OEM support in South Africa which is not helpful, it can be difficult. They should add an office back to the country because it was better."

"NetApp is costly when compared to Dell."

"The product must support more drives."

"It's not a cheap system. It is very expensive. The pricing has been ridiculous every time that we had to renew the support."

"The product should improve its user experience."

"It's hard to find in-person training that fits our schedule in our area. They offer a lot of online training, but we need somewhere to go because we can't really get away from the office."

More NetApp FAS Series cons

Pricing and Cost Advice

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

"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."

"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."

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

"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."

"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 licensing is on a yearly basis."

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

More Pure FlashArray X NVMe pricing and cost advice

"I liked the price point when we purchased it."

"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."

"Pricing for this product is manageable, though slightly higher than comparable products."

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

"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."

"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."

"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."

"While it has a good price to start, they could always make it cheaper."

More Dell Unity XT pricing and cost advice

"We purchased it for four years, and it wasn't expensive. It was reasonable. Every company has a different agreement with NetApp. We got everything we wanted with all the bells and whistles and all the features and functionalities."

"Cost effective storage for all performance levels (including all-flash)."

"It is expensive."

"The pricing of NetApp FAS Series is not cheap, but in comparison to other vendors, NetApp FAS Series is affordable because they also have deduplication, compression, and inline compression. They focus on storage only, which is really good; it works."

"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."

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

"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've sold arrays for as little $20,000 USD and as high as $300,000 USD."

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
