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.
Haseeb Khalid Sheikh - PeerSpot reviewer
End-to-end NVMe capabilities helps improve availability, performance, and capacity
The solution's most valuable feature is the data reduction ratio. You can store a 5:1 ratio of your data in Dell PowerMax NVMe. For example, if you have 200 terabytes of usable capacity, you can save up to five times of data on that capacity. That means you can save one petabyte of data on just 200 terabytes of usable capacity. The solution's end-to-end NVMe capabilities have improved our operations. Everything is fast, and you don't have to map your storage to old hybrid storage technologies. Our organization has experienced positive change, and the solution has improved our uptime, availability, performance, and capacity.
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

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"The database workloads are pretty fast because I frequently move data from here to there."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"It has good, reliable, fast storage."
"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."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"One of the best features is the support, which is excellent."
"You can use PowerMax for all workloads and consolidation. We have used it to scale thousands of VMs."
"The performance is very good on our servers. It's superior. And the QoS capabilities for providing work congestion protection are also important because about 99 percent of our servers are production servers."
"The number one most valuable feature is reliability. I want to go home at the end of the day and come in the next day knowing it works, especially since we have storage offshore."
"I am impressed with the tool's reliability since we see a few hardware failures with it. Also, the solution's replication configuration is good."
"The tool is a fast-performing asset. It can perform millions of transactions within a second. I like the tool's architecture as well."
"Enterprise Cloud Storage is the most valuable feature, along with the data services which come with it, plus the deduplication and compression."
"We are most interested in cloud utilization."
"The performance is very good. Our predominant workloads are all less than 5 milliseconds and it's most common to have a sub-1-millisecond response time for our applications. In terms of efficiency, we've turned on compression and we're able to get as high as two-to-one compression on our workloads, on average."
"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."
"Compared to our old platform, everything is more tightly integrated. I don't have to go to different sections to do something. A lot of it is wizard-driven, so it's an easy to use system."
"The setup and installation procedures are easy."
"We just recently started using the Dynamic Pools, so while it's scalable, we actually find it valuable that we can just pop in one or two drives when we need to, instead of having to add a whole RAID set. That has actually been very handy for us."
"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."
"On the Data Domain side, the most attractive feature is the compression ratio, which none of the other products in the market are currently able to provide. On the Unity side, what customers mostly like is the availability guarantee."
"The ease of management and “user-friendly” management environment (GUI)."
"The NAS is also extremely easy to set up."
 

Cons

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"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."
"It is on the expensive side."
"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."
"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."
"The tool's pricing is higher than competitors."
"We need better data deduplication."
"The disadvantage of PowerMax is its cost. It is expensive, mainly due to pricing."
"Since the merging of EMC and Dell into Dell Technologies, there has been a hurdle that they've had to overcome, and they're not over it yet. It takes two to three times longer for things to get fixed than it did when they were separate companies. That is something that has to be fixed."
"If you go to Pure or you go to NetApp, they deliver in one month. If you go to Dell or HP, they will take up to six months for delivery. This is not a business model for today."
"The tool is costly compared to other similar products. The product's pricing needs to be improved. I would like the product to include the replication feature in its future releases."
"There are some stability issues that we just recently experienced. We hope the next release will solve these problems."
"The price cap of Dell PowerMax NVMe is very high."
"Dell can improve the Service Level Agreement (SLA) compliance. Sometimes, when we need to replace a component, the SLA says four hours, but for some reason, the technician doesn't arrive until the next business day or even six to eight hours later before the case is placed. So, focusing on respecting the SLA is where Dell could improve."
"The disadvantage of PowerMax is its cost."
"Things that could be improved include one-to-many replication, data deduplication, and asynchronous Fibre Channel replication. It is asynchronous on iSCSI and I would like to have that on the Fibre Channel. Unisphere-wise, I have to log in to each Unity as a unique environment. In VNX, I logged in to the domain and I was logged in to every VNX. So that's missing."
"The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult. They should improve this to have a better reporting system."
"Dell Unity XT’s price needs improvement."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"The iSCSI and the VMware integation using vSphere could be less confusing."
"This solution would be improved with the addition of flexible raid volumes."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
 

Pricing and Cost Advice

"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."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"Given its price, Pure is not the first option."
"Our licensing fees are $500,000+ USD."
"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."
"I think it is an expensive tool, but it is the best product. I think it is expensive and the cost one must pay for the best solution."
"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 for this solution is good compared to other products in the market."
"The cost has room for improvement."
"The pricing is comparable to other vendors."
"The pricing might be a bit high for small organizations, so it's more suitable for larger enterprises."
"We hope that with the combination of both NVMe and SCM the next PowerMax will be much cheaper that the one which we acquired."
"From reclaiming data center space which is so tightly constrained these days, it will pay for itself in a short amount of time, which is fantastic. Anything we can do to get more out of our current physical data center space helps us a ton, and PowerMax has helped enable that."
"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."
"The solution should be cheaper."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"Pricing for this product is manageable, though slightly higher than comparable products."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"We checked both HP and Dell and we determined that Dell EMC was a better option."
"This solution offers great pricing."
"The solution is very expensive."

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.
