Works well, is easy to implement, and has upgrade analysis capabilities
Currently, it's our tier-one storage. We use it mostly for our Oracle databases It has drastically improved the performance of our high-end Oracle databases and allows us the ability to replication to a DR location with ease. We love the product. Pure Storage works really well.  The CAT tool and…

Reduces the footprint, is easy to use, and can handle heavy workloads
The systems I currently have in place are old, and their support is running out. They're at the end of their life cycle. One of the key improvements that PowerStore is going to bring is that it will enable me to shrink the physical footprint. I'll be going from 5 physical HP arrays, which are about 12 racks in size, down to 4 PowerStores, which can fit on one rack. As a result, I'll be able to shrink the footprint, save power, cooling, etc. I will also be able to improve the existing performance and longevity of the platform. When we put the PowerStore in for the Oracle database, it was previously on NetApp. The staff wanted to do snapshots but also clone, and then be able to clone from a clone to add it to another system. PowerStore enabled them to do just that. They not only got their performance back to where it needed to be from previously being on the NetApp array but also got some of the feature functions that they require for the application.

Easy to set up with good data compression technology and useful deduplication
The initial setup is very straightforward. Even upgrading the firmware is very nice. You don't need to shut down. Previously, we used to have a shutdown, and now we hand over to one more processor, upgrade the one processor, and then switch back to this process, and then we'll do the upgrade for the process so there is no downtime. I'd rate the ease of implementation nine out of ten. Since we are holding almost all the data, which are all critical and confidential, the deployment is always on-prem only. It takes a maximum of two to three hours. The solution is almost finalized before ordering. We plan what has to be done, and how many services have to be connected through the HBA. Based on that, the number of fiber ports should have been ordered along with the system. Normally, it comes with two fiber-channel HBA adapters. We used to order with four channels instead of going for a sand switch. We connect three servers directly into process A and process B. Before getting into the server, all the servers should be up and running with the HBA connector with the fiber cable ready. Once we install the server, we will see if the firmware is up-to-date or if it is one month old since the shipment takes at least one or two months before it reaches our hands. If there is any new update, we will check with them to see whether the new firmware is good or if there are any bugs in it. If the support team says there is no bug, it means we will update the firmware and create a pool. If it is a hybrid pool, we'll do a mix and combinations of flash as well as the NSS for the images. For the data, we have only the flash itself, and we use a rate six for the data. Previously, with the regular SaaS drives, we used to have a rate ten; however, with the flash drives, we used to have rate five or rate six only. Normally, in-house inside the rack, we need two people. Otherwise, one engineer itself will do. If it is a flash drive, only one person itself will be enough. If it is three bay drives with 144 TB or 288 TB, then we'll go for one more person to fix inside the rack. Once it is fixed, the installation will be done only by one person. For maintenance, normally, we check the firmware updates within a month, or we check every 30 to 45 days to seek out firmware updates. We provide maintenance to our customers. For other issues, we might call technical support. Most things we can manage.

Quotes from Members

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

Pros

"It has good, reliable, fast storage."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The high availability of the product is the most valuable feature."
"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."
"Technical support has been helpful and responsive."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"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."
"The most valuable features of this solution are its ease of use and performance."
"Migrations are very easy and fast."
"This solution is highly flexible and offers efficient online compression capabilities."
"Dell PowerStore is very simple to implement, and its user interface is very simple."
"It's really good, price-wise. It's cost-effective."
"Has a great mapping feature."
"The product's initial deployment phase has been straightforward."
"The solution's technical support is excellent. I rate the technical support a ten out of ten."
"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."
"When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good."
"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."
"The setup and installation procedures are easy."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"We use it to implement all our VDI solutions."
"The UI itself is fantastic, and the ease of administration is far better than Unisphere or Navisphere ever were. It's very easy to manage. The fact that it has built-in APIs means our automation people can help us automate a lot of tasks, and that has been helpful. And, of course, it's really fast. Obviously, that doesn't hurt anything at all."
"I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid."
"It has a very intuitive web console that runs in HTML5 and makes navigation and administration fairly easy."
 

Cons

"The UI for this solution needs to be improved."
"I would like to see replication and DR features in the next release of this solution."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"The software layer has to improve."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The tool's portfolio is minimal. It is expensive."
"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."
"I would like to see a Snapshot feature. Currently, it is unable to occupy the capacity."
"More demonstration and training options are needed."
"The price is on the higher side."
"The solution only does thin provisioning."
"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."
"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 only area I can highlight for improvement is that the 4:1 data reduction target has not been reached. This may be due to an issue with Dell EMC's initial analysis of data compression. As a result, we have had to add new physical disks to reach our goal of total available disk space."
"The support team should have more people with experience in the solution's installation process, as it is one of the areas where I see certain shortcomings."
"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."
"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."
"The price of Dell Unity XT could improve."
"This solution could be improved by offering containerization. This is something many of my customers are looking for."
"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside."
"The biggest one for us, and the reason we don't use it more, is that we can't throttle the replication speed. If it's on, it's on. So we have to be a little more WAN-sensitive, in some applications, which means we can't put it everywhere. That's the biggest issue for us, by far."
"I would like to see more integration with other products."
"Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product."
 

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."
"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."
"Our licensing fees are $500,000+ USD."
"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"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."
"As far as the licensing costs, everything is included in the license."
"We only have a single machine and we are currently using half of the hard disk slots. We have asked for an upgrade for the rest of the hard disks but, from my point of view, it costs too much. We have 12 to 15 hard disks inside and if we try to upgrade only the hard disks, it costs the same as the complete system. This is something I don't understand."
"There are no separate licenses required as all the basic licenses are included in the bundle."
"Dealing with the licensing part of the product is very simple, especially considering the fact that we don't have many licenses associated with the tool."
"The price of Dell PowerStore could improve. The price should be managed more compared to Huawei Dorado or IBM All-Flash series."
"Dell PowerStore is not a cheap solution."
"It is easy to work with Dell from the licensing perspective."
"The software features are included in the pricing without any additional purchase requirements."
"The price is not cheap, but it's worth it for the features you get from the storage. If you can afford it, you are probably buying the best solution that you can have for this virtual environment."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"It is a good return on investment."
"I rate Dell Unity XT’s pricing a nine out of ten."
"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."
"Our costs are roughly $200,000 a year."
"The license is not required, but we must renew the support every year, every two years."
"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."
"This solution is a good price for what you get."

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.

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.
