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.
MayankChauhan - PeerSpot reviewer
Delivers essential support and performance for intensive operations in real-time environments
Our infrastructure is spread across the private as well as a public cloud. Our requirement was that the IOPS latency should not be more than one millisecond. If anything goes beyond one millisecond, it's a problem for us. We wanted a system that could handle the transactions and meet our latency requirements. There are performance benefits for sure. The amount of deduplication and compression offered by Dell PowerMax is quite good, especially with databases. Dell PowerMax delivers optimum performance and reliable support, integral for handling failures and ensuring operational continuity. The performance capacity optimization and support we receive from Dell are also valuable.
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.

Quotes from Members

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

Pros

"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."
"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."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The initial setup was extremely simple and straightforward."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"Technical support has been helpful and responsive."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The database workloads are pretty fast because I frequently move data from here to there."
"It is a fantastic Dell EMC product ever competing with all the vendors. It stands out in terms of performance. You can ask for mission-critical application workloads."
"Based on our experience with VMAX, there isn't any hardware failure or something like that in PowerMax. Performance-wise also, everything is fine. We haven't faced any performance issues or any hardware failure. Its performance is great as compared to VMAX. Its I/O per second rate is higher than the old model."
"CloudIQ has become an optimal tool for us to get the full picture of all the different arrays, from mid-tier all the way up. It gives us that single view and the ability to launch the Unisphere. That is really is powerful in being able to manage the array."
"Enterprise Cloud Storage is the most valuable feature, along with the data services which come with it, plus the deduplication and compression."
"I have been highly satisfied with the resiliency and scalability of the solution."
"It was easy for teams to pick up the technology with very limited exposure and training, then implement and support it."
"We were able to move away from a middleware solution for high availability, going right to snapshots and data replication on arrays."
"The response time, compared to XtremIO, is far better."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"It is scalable. Customers are going more into distributed architecture, so the Unity definitely has a scalable architecture built into that."
"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."
"It's easy for us to use because we use other solutions which are built for Unity, like VMware, which are recovery points. They work with the Dell EMC Unity system, as these products integrate well in our environment."
"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."
"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."
"To be programmatically administered is huge, it is one of the key features that we like about it."
"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."
 

Cons

"The tool's portfolio is minimal. It is expensive."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"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."
"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 would like to see more visibility into garbage collection and CPU performance in the GUI."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"The UI for this solution needs to be improved."
"Dell PowerMax needs more connectivity options for projects that require separate web access."
"I would like a more informative CloudIQ for iOS. What you can see via the web UI significantly differs from what you can see via the web application."
"We had challenges again with the initial setup. I don't know if there was a gap during the requirement-collection phase, but the box was partially delivered to us with missing parts and it delayed the implementation by about 60 days. It was not as smooth as I would have hoped."
"My understanding is that Dell PowerMax is very expensive."
"Dell PowerMax needs more connectivity options for projects that require separate web access."
"The one area for improvement in Dell PowerMax NVMe would be to align the features of the on-premises version with those available in the cloud, as this would provide added value and flexibility."
"I would like to see the rack change. They have defaulted to the standard rack, so our fiber cables are crowded when we shut our back door."
"With Dell PowerMax, engineering always has to be involved if you want to expand the system with a couple of disks or anything. It is quite a tedious process."
"Software updates have to be downloaded to the root of the device. This pushes the available space to 95% utilization."
"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."
"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."
"The pre-sales technical support and technical engagement could be made better for this product."
"There is an ESRS problem that we're facing where, for some reason, the other Unity has not been able to register to EMC. The support information is not upgrading and nobody can tell me what is wrong with it. It's a minor issue, the ESRS is still working, but it is something that is very confusing and nobody seems to know what to do about it."
"We have only used this solution for less than one year so I don't have any improvements suggestions yet."
"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."
"It would be great if the solution could integrate an NVMe disk."
 

Pricing and Cost Advice

"We pay approximately $50,000 USD per year in licensing fees."
"With VMware, we pay $300,000 annually."
"The product is expensive."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"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 licensing is on a yearly basis."
"The PowerMax appliance pricing was reasonable. Dell EMC quoted us a substantial discount."
"The labor savings and support have been significant. If we're talking 100 hours of labor every three months, that is 100 hours of a database engineer costs. There are performance latency numbers as well as costs associated with recovering data that gets lost, and this system doesn't lose data. You can look at numbers that go around the cost of downtime, if data is not available. This system doesn't go down. Everyone's ROI is going to be unique, but the dependability and performance of the system combined with its ease of operation will definitely save businesses of all sizes money."
"Support pricing is very high. Our support contract is about to expire and Dell EMC provided us with an extremely high renewal quote. It was four times more than the support contract for our previous EMC VNX solution."
"The cost is expensive. While VMAX now has good pricing, PowerMax is a little expensive."
"The price is on the market. It's not inexpensive, but it's available on the market."
"It is high-end storage and it is a bit expensive, but it is doing what it is meant for: running business-critical applications or latency-sensitive applications..."
"The pricing is comparable to other vendors."
"The pricing is competitive. I would rate the pricing of the solution a six out of ten."
"The solution is very expensive."
"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."
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"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."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."
"At the end of the day, the licensing cost is key, because every customer has a pain point, that the cost of each piece is high. So if they would bundle everything in a package, that is how the competitors are selling their footprint."

I have used all, EMC, and HPE 3Par, VNX, Unity, etc. All are OK. But for long term Flash Storage, I would take a look at Hitachi F Series. Best reliability hands down and they provide non-disruptive migrations, no server downtime, no scheduling with users, etc. NDM makes Hitachi a no brainer.
