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

"I appreciate the performance."
"The most valuable feature of this solution is its ease of use."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"Overall stability is very good. It is a very stable solution."
"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 solution is very straightforward to set up."
"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."
"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."
"The solution has a wide variety of valuable features. The data progression works well. We use the snapshot functionality quite a bit and really like it."
"The product offers good performance and is quite powerful."
"With federation, you can have multiple systems across sites. You can treat them as one, and with a live migration, volumes don't go down. You can move them from site to site, doing maintenance, and keep your environment up."
"One time, we had a drive fail and we were notified before we even saw it on the device."
"Its leading feature is the price-performance ratio, which is very good."
"The most valuable feature is the no-forklift upgrade. While the thing is running, I can change out the controllers one at a time and keep the customer up and running. I can add shelves and storage and SSD drives or spinning drives to the system, while it's running. I can bring all that in and rebalance the load across the new disks or, if we take disks away, rebalance the load across what's remaining, and it just works."
"We replicate between SAN to SAN for a lot of features and supportability. It also helps us when we want to upgrade to a newer SC Series or move the data from one data center to another."
"This solution is easy to use."
"This has been one of the most reliable storage systems that I have ever used."
"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

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"We have run into a couple of instances recently where we are running out of space."
"They could add more support for file storage and different types of storage."
"The only area I wish to see improve, I believe is coming, is in the FlashBlade product."
"Pure is not flexible on your datapak expansions. You're locked into a certain amount of storage."
"The tool's pricing is higher than competitors."
"The software layer has to improve."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"Overall, I'd like to see more synergy between Dell EMC's higher-tier platforms and their mid-tier platforms."
"In the future, I want any box that comes on-premises to have the provision to integrate with cloud storage."
"We have seen some degraded throughput with mixed workloads."
"The cost of the solution could be better."
"Compellent comes in the form of a component that's not true of a unified storage platform."
"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."
"Dell SC Series is no longer available, while Dell PowerStore, which supports NVMe over TCP, is different and not very affordable."
"In terms of additional features, I would like to see some kind of I/O meter, to indicate what we are using in terms of performance. I would like to see automation with that, where it would give me the trends. I want to know those things easily, to help me know where issues are going to occur."
"The write performance could be improved because it is less than half of the read performance."
"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

"We pay approximately $50,000 USD per year in licensing fees."
"As far as the licensing costs, everything is included in the license."
"The licensing is on a yearly basis."
"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."
"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 product is expensive."
"We have found the solution to be affordable."
"The pricing of Dell EMC Compellent is competitive."
"The scalability seems a bit more expensive than even buying a brand new one so far. That has been kind of a drawback."
"Pricing depends on varying life cycles."
"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."
"The pricing is reasonable, but it is expensive."
"This product is too expensive compared to others, and I don't see any value in using 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."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
