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.

Integrated AI and clustering enhance storage operations effectively

I promote and recommend Dell PowerStore for all workloads to my clients and customers. Most of my customers have one appliance per site. Approximately 80% of my customers have Dell PowerStore implemented in their data centers. We always use CLS as another Dell solution for cybersecurity and data security. The CLS is integrated with the Data Domain, PowerProtect Data Domain, not with Dell PowerStore. Windows, Linux, and some customers use Red Hat or SUSE. We have many operating systems working with Dell PowerStore in the same environments and data centers. CloudIQ and Storage IQ are used by some customers, but Apex AIOps has not been widely adopted yet. Dell PowerStore has integration with VMware and Kubernetes. Most workloads work fine and have very good integration with Dell PowerStore, except for one or two specific workloads in the market. On a scale of one to ten, I rate Dell PowerStore a nine.

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.

"The most valuable aspects of Dell PowerStore are the promising roadmap, and the interesting features to come."

"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."

"The support for Dell PowerStore is exceptional; I would rate it at probably an eight or nine out of ten."

"The thing that I appreciate the most about Dell PowerStore is how easy it is to upgrade; the upgrade process is very simple, and I really appreciate how easy it is to connect my hosts to Dell PowerStore, as the environment automatically detects new fiber channel HBA ports for all the hosts that we connect to."

More Dell PowerStore pros

"They have a Unity REST API that I use to automate some of the storage stuff. I'm just getting started with it, but it seems pretty easy to use."

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

"The Snapshot feature is key."

"Setup is simple."

"It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it."

"The scalability is really good now that they have the Dynamic Pools. We don't always have the money to buy complete write sets when we have to expand the storage, so now with the Dynamic Pools we can add disks on the go."

"Its quick integration with VMware. The ability to stand up a data store in one place, where you don't have to go and rescan for the data store through the vCenter Client, as well as SMB shares. This ended up being a big selling point for us."

"Performance is a top feature."

More Dell Unity XT pros

Cons

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

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

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

"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."

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"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."

"In terms of what needs improvement, the dashboard and management could be simplified."

"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."

More Pure FlashArray X NVMe cons

"There could be better reporting."

"I have realized nothing exemplary from using Dell PowerStore, except hat the user interface is clunky, and we've had issues with that."

"There is an issue with Dell PowerStore related to future expansions which are software-related."

"We'd like to see some improvements on the security side."

"I have not seen anything specific. The only thing I can think of that needs improvement is the price."

"Dell PowerStore should offer more cybersecurity and warehouse data security."

"Dell PowerStore does not meet the needs of a small organization; Dell has Unity which meets the entry-level or SMB segment."

"One improvement I would suggest relates to the service that pings Dell when there's an issue. I would say it needs to be more transparent."

More Dell PowerStore cons

"Issues with slow responses from the support team."

"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps."

"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."

"The pricing is a bit high. We'd like it to come down."

"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."

"Software updates have to be downloaded to the root of the device. This pushes the available space to 95% utilization."

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

"It could be a little easier to attach it to a network file system."

More Dell Unity XT cons

Pricing and Cost Advice

"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."

"The licensing is on a yearly basis."

"The product is expensive."

"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."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"When we compared it with the other solutions, the pricing of PowerStore was equal. The pricing is good."

"Dell PowerStore has been priced aggressively, especially when compared to other NVMe storage options. It is likely one of the most cost-effective options for organizations seeking a pure NVMe play in terms of pricing."

"The solution’s pricing is always too high."

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

"We are currently using Dell PowerStore for our smaller storage and there is no competition for pricing."

"Dell PowerStore is not a cheap solution."

"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."

"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."

More Dell PowerStore pricing and cost advice

"This product is cheaper than the EMC VNX solution. It is good for small businesses."

"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."

"Compared to other EMC platforms, Unity is nice because it is all-inclusive, in terms of the licensing model. That's unique for them, compared to other manufacturers. It is beneficial. We could use replication, native, right out-of-the-box."

"We purchased a five-year warranty."

"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise. Huawei and Lenovo are very price competitive. Looking at the price point for a country like Sri Lanka, where we have a very low economy, I think you need to look at a pricing mechanism that is a bit more flexible."

"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.""

"The price is very reasonable."

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

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."
