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

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

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

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"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."

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

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

"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."

"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."

More Pure FlashArray X NVMe pros

"The data encryption is good and available in a standard license. There are snapshot and backup capabilities."

"It's a great product. Integrating PowerStore with the IT workflow is easy."

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

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

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

"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."

"The most valuable feature of Dell PowerStore is the all-NVMe flash storage. This is the most powerful feature of this series. It supports compression and duplication leads."

"PowerStore is easy to use. All the drives use soft encryption. To upgrade it, you download the app, and it runs by itself. It's very easy to deploy, share, and create volumes."

More Dell PowerStore pros

"The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data."

"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."

"It is scalable. Customers are going more into distributed architecture, so the Unity definitely has a scalable architecture built into that."

"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."

"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."

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

"All-flash array eliminates all the overhead of tiering and a lot of the data structuring overhead involved."

"It has saved us time when provisioning new storage, so we're trying to automate that process."

More Dell Unity XT pros

Cons

"We need better data deduplication."

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

"Maybe the price can be reduced since the solution is very expensive."

"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."

"The software layer has to improve."

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

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

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

More Pure FlashArray X NVMe cons

"The setup process could be improved. We had some issues regarding configuration and the time it took to do things. It wasn't specifically the people we worked with, but more the process and how it's done. They can work on that."

"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."

"Sometimes, you have to go back and forth with the technical support team, where they want you to do something you've already done."

"The customer support is slow and has room for improvement."

"Reporting is an area that could be improved. It's very simplistic sometimes, and some of the very technical guys on my team want to see more of the details and be able to massage the report a little bit better."

"When you create a case on Dell's support website, you don't always get someone who is experienced in the kind of systems you need help with...making it an area where Dell's support team needs to make improvements."

"We would consider this solution if the pricing is competitive with other options, as it offers a very good solution. However, the current price is slightly higher than the competition."

"The only thing is that with PowerStore, we don't have a solution for the file object."

More Dell PowerStore cons

"We would like to see more advanced integration capability added to this solution."

"If there's anything Dell EMC could do to get the same performance for a cheaper price, that would be great."

"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."

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

"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."

"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."

"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."

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

More Dell Unity XT 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 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."

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

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

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

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

"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."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

More Pure FlashArray X NVMe pricing and cost advice

"The licensing for this solution is good and is in the mid-range tier."

"There are no separate licenses required as all the basic licenses are included in the bundle."

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

"Dell PowerStore is not a cheap solution."

"With compression, we were able to have a solution within our company's budget. We include a clause in the contract with Dell that states if the compression ratio is not met, we will adjust the workload accordingly."

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

"The pricing structure and licensing model of Dell PowerStore are very good and I like it. We chose it because it was reasonably priced and met our requirements"

"I rate the price of Dell PowerStore a seven out of ten."

More Dell PowerStore pricing and cost advice

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

"The solution is very expensive."

"The solution is extremely functional for the price that we pay for it. It is worth the investment."

"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."

"The price is good for commercial grade storage arrays."

"It is shipped with all licensed, included for this product range, no need to buy additional licenses"

"We have to apply for a license for each system."

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

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

Sep 19, 2023

The Unity 300/400/600 generation (1st) is really old stuff, lateron came the 2nd generation of 350f,450f,650f (hybrid or full flash) and still later cam in the 3rd generation 380f, 480f,680f & 880f As usual the CPO/Cores and cache increased everytime, the code is pretty much the same. The x00 generation is already obsolete and by next year the next generation x50 is going to be obsolete from a service point of view. Here is how it goes. Dell Puts forward to replace * the Unity XT 380F by an Powerstore 500T * the Unity XT 480F by a Powerstore 1200 * The Unity XT 680f by a Powerstore 3200 * The unity XT 800f by a Powerstore 5200 There is even a Powerstore 9200 Currently you have the Unity x80 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/FC but NAS storage as well, 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. the Powerstore offloads its compression/deduplication efforts from the Processor to a hardware component in charge of it (like the PowerMAX and likely the same device and Compression Algorithm). The price of the device is pretty much dependant on the price of its media, and therefore the Powerstore T1200 is the absolute winner as you can double the data saved to it compared to the Unity alternative. There is one caveat, when you initialise your Powerstore you either initialise it as a NAS or Block Device appliance. Whereas on the Unity part, you could use both options at the same time.. 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.To you can , have true Active/Active volumes and go next level with MetroCluster volumes and go beyond VMware Site Reovery Manager to organise your failover/test failovers and protection groups. You can actually leave aside VMware Site Recovery manager and do all from within Powerstore and use its Recoverpoint for VMs add on (similar to Veaam replication but a with an storage appliance in support. 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, unless you would go for a mixed chassis providing both Block Storage & FileSharing. Unity allocates RAM ressources dynamically when used for FC/SCSI AND NAS , whereas the Powerstore is initialized as either a NAS or BlockStorage at installation time. 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."
