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.

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

"Everything, especially the VMs inside, is pretty fast."

"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."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"The most valuable features of this solution are its ease of use and performance."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"What I really like about this program, is that it is easy to use and easy to configurate."

"The high availability of the product is the most valuable feature."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

More Pure FlashArray X NVMe pros

"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."

"Dell SC Series offers a lot of performance, being one of the best performing storages Dell ever made."

"This solution is easy to use."

"The solution is stable."

"I can mix and match the drives, using older mechanical devices and the latest SFP drives in a single solution with different enclosures."

"The most valuable feature is the speed for the end-user."

"Its leading feature is the price-performance ratio, which is very good."

"The performance benefits weren't surprising, we expected that. What we didn't expect were the densification benefits that we got out of going all-flash. We're able to put more applications on the arrays because of how all-flash performs. The way some of the application profiles have responded to all-flash has been really pleasing."

More Dell SC Series pros

"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

"I'd like to see the product implement active replication for vehicles such as VMware."

"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."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"In the future, I would like to see integration with enterprise backup systems."

"Maybe the price can be reduced since the solution is very expensive."

"We need better data deduplication."

"The software layer has to improve."

More Pure FlashArray X NVMe cons

"The initial setup is somewhat complex and should be made simpler to do."

"I would like to see higher compression, dedupe, faster I/O, and bigger drives."

"The interface could be improved. It should have an application point of view."

"We have seen some degraded throughput with mixed workloads. We have been working with Dell EMC to correct some of these latency issues."

"If Dell SC Series could have supported the protocol NVMe over TCP, that would have been great. It does not."

"What I understand is that this is a 13 year old architecture, so it has lived its life and they're phasing it out. Honestly, we were initially struggling with the integration with VMware (but it was fixed with the VMware 6.5) and, then, it was around a 10GB network. At that time, it had the longevity to go to 100GB as well. It got us thinking about, when we go into the containerized architecture, what do we need to do to fix the infrastructure?"

"Overall, I'd like to see more synergy between Dell EMC's higher-tier platforms and their mid-tier platforms. What I have said, constantly, to my partners at Dell EMC is that the clear articulation of the path is really important to us. In that vein, what I'd also like to see is, with the migration strategy that's built into this product, a lot more attention paid to Dell's - in particular - legacy platforms and how we get from some of our legacy EMC platforms onto this platform with a straight-through migration and scaling strategy, not host-based migrations and not piecemeal... Dell EMC would do well to focus more on my ability to skip a generation, rather than having me take individual hops because I can't greenfield my way into a software-defined data center fast enough. This journey of multiple hops is not helpful."

"I would like to have 100% functionality through the web app."

More Dell SC Series cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

Pricing and Cost Advice

"We pay approximately $50,000 USD per year in licensing fees."

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

"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 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."

"The support cost per array is about $20,000 a year for 24/7 support."

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The pricing of Dell EMC Compellent is competitive."

"There are costs involving the solution, vendor fees and product safety which are additional."

"It's absolutely affordable. Again, not having to do a forklift upgrade like some of the others have had to do in the past, it's very affordable for our customers and they continue to buy."

"Pricing depends on varying life cycles."

"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."

"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."

"It's a very affordable solution."

"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."

More Dell SC Series pricing and cost advice

"We acquired VAST Data as a one-time, capital purchase."

"Price-wise, VAST Data is not the cheapest, not the most expensive one."
