Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

User interface offers clarity and detailed information while technical support consistently delivers
The best features of Dell SC Series are stability and replication. The replication solution is excellent, and they have a solution named Live Migration. It is a robust platform. The interface and the GUI (graphical user interface) for administrating the Compellent are exceptional, with abundant information that is very clear. The management capabilities are excellent, and the stability of our storage hardware is remarkable.
Alan Powers - PeerSpot reviewer
HPC CTO at a manufacturing company with 10,001+ employees
Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"One of the best features is the support, which is excellent."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"The latency is good."
"I appreciate the performance."
"It has good, reliable, fast storage."
"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."
"Its feature set is superior to some of the other platforms."
"It is suitable for small or medium businesses."
"With auto-tiering, it's easier to understand than most arrays, knowing that all of your writes go to the tier that you specify, with easy-to-create storage profiles."
"This solution is easy to use."
"The setup is straightforward."
"They have a feature called Live Migrate; it's been very, very useful."
"It has good dedupe and compression. Also, the built-in data migration capabilities are pretty good, as is the federation. When we started migrating the workloads from different storage platforms, like NetApp and XtremeIO, it helped us in moving to that direction."
"Its leading feature is the price-performance ratio, which is very good."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
 

Cons

"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."
"In the future, I would like to see integration with enterprise backup systems."
"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."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"Maybe the price can be reduced since the solution is very expensive."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"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."
"Some menus aren't so intuitive."
"One option I would like to see is, when you're up on the view-screen, to be able to incorporate getting to what HPE call the iLO, the Integrated Lights-Out. To be able to get that instead of having to go back and trying to find IP addresses and re-institute those would be good. It would be good to be able to that put on the initial splash screen."
"I don't think the solution is very scalable."
"The interface could be improved. It should have an application point of view."
"I would like to have 100% functionality through the web app."
"Dell SC Series is no longer available, while Dell PowerStore, which supports NVMe over TCP, is different and not very affordable."
"While there's always room for improvement in everything, I can't really think of a specific feature of the solution that requires immediate attention."
"Compellent comes in the form of a component that's not true of a unified storage platform."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
 

Pricing and Cost Advice

"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."
"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."
"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."
"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."
"As far as the licensing costs, everything is included in the license."
"The licensing is on a yearly basis."
"Always keep in mind, this is not just a enclosure with disks is a complete SAN as a service. There is software, license, and storage in one single solution."
"We have found the solution to be affordable."
"The pricing of this solution is competitive."
"The SC Series was priced fairly. I wouldn't call it either expensive or cheap because we had a very tight budget, so if they were able to fit in that type of budget, they met our expectations."
"We have the basic license for the use of this solution and it is a permanent license. The overall cost could be less, it is expensive."
"We were able to afford two tiers of flash storage at a price where the competition was giving us one tier or just a handful of discs."
"We have found it to be affordable. Comparing the cost with other hardware, it seems to be right in line with the compute and the storage that we get with it."
"We have reviewed many platforms over the years. It is probably the best solution for its value."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
