Eugene Hemphill - PeerSpot reviewer
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.
Syed Habib - PeerSpot reviewer
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.
Gastone Canali - PeerSpot reviewer
Provides good stability and is reliable in terms of performance
The solution is reliable in terms of performance They should include a snapshot feature for the solution. We have been using the solution for two to three years. The solution is stable. We have 60 solution users in our organization. The solution's initial setup process is easy. It takes three…

Quotes from Members

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

Pros

"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."
"Technical support has been helpful and responsive."
"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."
"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."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The database workloads are pretty fast because I frequently move data from here to there."
"The solution is scalable."
"I appreciate the performance."
"We are happy with the way we have Dell EMC Unity XT configured."
"It is easy to manage. A lot of the system manages itself."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"It's very reliable. I have not had an issue with Dell EMC Unity."
"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."
"The ease of management and “user-friendly” management environment (GUI)."
"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's a much smaller footprint than our older storage arrays, which take up some six tiles, a lot of space in the data center. The Unity's are a lot smaller, and they're a lot faster."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution is very easy to set up."
"Lenovo ThinkSystem DE Series is simple to use"
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
 

Cons

"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."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"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."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"They could add more support for file storage and different types of storage."
"It's very frustrating that it's not backward-compatible with the previous platforms, so it's a struggle for a lot of our customers."
"They should have more wizards for customers so they can do more of the self-service types of functions, in terms of upgrades and patching, although it's pretty easy right now."
"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."
"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."
"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."
"We integrated it with vSphere but that integration was "iffy". It was okay but we had a few challenges with it."
"It needs more functionality and the ability to move across more landscapes."
"Dell EMC Unity XT should present a path or a roadmap on how they could put their products on the cloud. This would have some value for their current customers."
"There could be a snapshot feature in the solution."
"The features are limited."
"The solution could be more scalable, although it suits our present needs."
"It would be useful to have structured solutions replicated to other sites."
"Improvements can be made to the product's performance."
"Its performance could be faster."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
 

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."
"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."
"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."
"As far as the licensing costs, everything is included in the license."
"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."
"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."
"Our licensing fees are $500,000+ USD."
"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"Go with the virtual appliance versus the hardware."
"The solution is extremely functional for the price that we pay for it. It is worth the investment."
"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.""
"Looking at it based on cost per gigabyte, it's certainly very effective."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"It is an expensive solution."
"The solution's price could be better."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"We have a five-year contract for providing support."
"The pricing is fair and low compared to other products in this category."
"The pricing for this solution is good compared to HP or Dell EMC."
"The best thing about this solution is its price, which reduces our costs."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
