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.

It's constantly enhanced and has impressive reliability and data compression

The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal. I hope Dell addresses that. Everything is pricey these days anyway. It is not like the old days of Compellent. We used to be able to see the metrics for our customers. On Compellent, we could look up that customer and see all the metrics. That is not allowed for us now. We cannot do that anymore. I have to be explicitly allowed by the customer to do that, and some companies' security does not allow that.

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.

Quotes from Members

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

Pros

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

"It has good, reliable, fast storage."

"I appreciate the performance."

"Overall stability is very good. It is a very stable solution."

"The solution is very straightforward to set up."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"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."

More Pure FlashArray X NVMe pros

"The tool's most valuable features are compression and speed."

"Dell PowerStore is more cost-efficient than other solutions."

"The solution's most valuable features are its form factor and switching to NVMe."

"It provides a big benefit when upgrading a new VMware environment. For example, in a big environment with 10 to 30 ESXs, you can take everything and put that into PowerStore. So, it is cost-effective, which is very important and has been massive for us. You reduce almost 80% from the hardware and work directly from PowerStore. Building hardware, especially in a big VMware environment, is a big issue for my organization."

"The latency and the security are the most valuable features of Dell PowerStore."

"The software upgrades are all included for no additional charge."

"It's really good, price-wise. It's cost-effective."

"The most valuable features of Dell PowerStore are the resilience, scalability, flexibility of expansion, and ease of managing the entire solution including the servers and storage."

More Dell PowerStore pros

"It has made deployment, configuration, and maintenance a lot simpler."

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

"The inline deduplication and data reduction capabilities have been the most valuable."

"It has reduced the latency in application and database reads and writes... All-flash, it's fast. We have the 650 model which is all-flash, upgraded from VNX. It just flies."

"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."

"We can sleep at night because the support is great."

"It has good performance."

"We can put all the virtualized servers in one place, so our customers can share and manage the devices very easily."

More Dell Unity XT pros

Cons

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"I would like to see replication and DR features in the next release of this 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."

"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 need better data deduplication."

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

"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."

"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."

More Pure FlashArray X NVMe cons

"When it comes to Dell PowerStore, I would like to see more integration and more security features included. It's unfortunate that the solution does not feature Flash trace."

"The data resiliency and cybersecurity features of Dell PowerStore are just normal and would be considered medium; we need additional components such as cybersecurity vault for increased resilience."

"Dell PowerStore has just caught up to some of the competition by introducing METRO nodes a few months ago while the competition has had the feature for years."

"The customer service and support are bad."

"PowerStore's management console could be improved."

"Could use some additional automation."

"The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal."

"There are certain shortcomings with the technical support team of Dell PowerStore, where improvements are required."

More Dell PowerStore cons

"Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that."

"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."

"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."

"Problems with I/O modules, with bugs that came out that really should have been caught before the product was released."

"I think Dell EMC should be more careful in appointing partners, and they need to have better control over their partners. And if their partner has some problems with them, we should not suffer."

"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."

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

"It would be great if the solution could integrate an NVMe disk."

More Dell Unity XT cons

Pricing and Cost Advice

"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."

"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 product is expensive."

"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."

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

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

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The price of Dell EMC PowerStore could be better, it is a bit expensive."

"We are happy with the pricing that we get from Dell."

"In the pricing and licensing department, the product is always too expensive."

"We purchased it with a five-year warranty."

"The software features are included in the pricing without any additional purchase requirements."

"PowerStore's pricing is reasonable."

"In terms of licensing, my organization has Dell Technologies End User License Agreement (EULA), but I don't know exactly how it works, though it is a big bundle of licenses for Dell Data Domain, Dell EMC Unity XT, Dell PowerStore, Dell ECS, and all such kinds of storage arrays."

"Dell PowerStore is more expensive than Dell EMC Unity All Flash. Dell PowerStore's performance metrics were way higher than what Dell EMC Unity All Flash offered."

More Dell PowerStore pricing and cost advice

"The license is not required, but we must renew the support every year, every two years."

"The pricing of Dell Unity XT is good."

"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."

"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."

"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."

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

"It is priced at around or under $50,000."

"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."

Which solution do you prefer: Dell PowerStore 1200 or Dell Unity 400?

Hello Yasin, The best solution depends upon your host environment. In general, PowerStore is more powerful than Unity but Unity is also a very good Storage solution.

See 2 answers

Cloud Engineer at a tech services company with 51-200 employees

Sep 19, 2023

The Unity 400 is a rather old, a much less powerfull solution and at its best holds ssd flashdrives if at all. Currently you have the Unity 8xx model, which has more CPU punch and therefore maxes out less fast on CPU utilisation. What this means is that you can add more shelves and disks and workloads to it before you hit the roof. The powerstore 1200 is an nvme storage, is 60% more powerfull (compared to FC/SCSI-SSD on Unity) in our case, and has higher datareduction rates. If the unity reaches out to a datareduction rate of 1.5 or 2, the Powerstore T1200 is capable of 3 to 3.5 datareduction, probably due to half its blocksize. The price of the device is pretty much dependant on the price of its media, and therefore the Powerstore T1200 is the absolute winner. . Another aspect is that the Powerstore can be used to build a cluster of arrays compared to the sync/asynch replication only feature of the Unity series, rendering the mirrored volumes unuseable unless one fails over to it, like in a disaster recovery scenario. . The Powerstore also allows true A/A volumes on both sides . What this means is that one can build stretched vSphere clusters and the loss of your array in one site will still allow writing to the alternate protected disk, transparently ! You can have site local writes to your volumes and remain in sync without a need to cross site write. . There is not much of a reason to settle for the Unity anymore, though some still prefer the Unity for NAS compared to Powerstore, but honestly speaking I won't recommend to use any of both for that purpose unless for limitted useage. Unity allocates RAM ressources dynamically when used for FC/SCSI AND NAS , whereas the Powerstore is initialized in a kind of split off of RAM ressources between NAS/FC SCSI at installation time. The ressource allocation is fixed and can't be altered lateron. Thats a hard call. So I'd favour the Unity only if you use it for low/moderate NAS needs in combination with FC/SCSI or block data and you don't have the budget nor the size to use a NAS optimised array on top.

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."
