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

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"The latency is good."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"Everything, especially the VMs inside, is pretty fast."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"It has good, reliable, fast storage."
"It's very scalable, especially with federation. If you outgrow the number of spindles that a unit can support, depending on the model, you can go into federation."
"The process of reallocating data from fast disks (SSD or SAS) to slow disks (SATA) gives you better performance and better use of resources."
"The most valuable features are the with back-end dedupe, and the thin nodes. For a 20TB or 60TB, we're using almost a one-to-two ratio."
"There's some new stuff coming with 7.3, which just got released, where they're spreading the sparing across the whole array, rather than having a dedicated spare disk, and have it sit there and do nothing until one of them dies, and then it kicks in - and having to rebuild all of that. Now, they'll do the sparing across all the disks and they say that is going to add not only space but performance to the array, with 7.3."
"The Dell support is helpful and the response is quick. The agents' knowledge is very good."
"I've found the stability to be very good."
"The solution is stable; we've had no problems at all."
"Customers are most impressed with SC's provisioning because you don't need to buy a large amount of storage upfront. It's pay-as-you-grow. It also has solid compression and duplication features."
"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

"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."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"We need better data deduplication."
"Adding some functions to the product would be beneficial."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"They could add more support for file storage and different types of storage."
"If Dell SC Series wasn't being phased out, adding an NVMe tier and secure snapshots like those on the PowerStore platform would be beneficial."
"Compellent comes in the form of a component that's not true of a unified storage platform."
"We can definitely see a need for it being a multi-controller system for customers who want to scale beyond the current capability. That's always a downside. A lot of the new systems are scaling vertically, they scale out, and the Compellent, of course, is controllers with shelves under it, so you don't scale out with it, unless you add another one. But if you do, they don't talk to each other, like some of the other solutions that we sell."
"The lower model, the 3000, should have duplication. It doesn't right now. It's only from 5000 that this is offered, but it depends on the performance. It could be they don't offer it on lower models because the duplication is too much of a burden to the performance."
"This product should be a lot more user-friendly."
"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."
"The price could be improved."
"Dell SC Series is no longer available, while Dell PowerStore, which supports NVMe over TCP, is different and not very affordable."
"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

"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."
"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 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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"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."
"Compared to other solutions out there, it's affordable."
"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."
"The pricing is reasonable, but it is expensive."
"It has a good price point and offers some value-added enterprise features."
"There are costs involving the solution, vendor fees and product safety which are additional."
"It's a very affordable solution."
"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."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
