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.

Storage solutions accommodate diverse drives and offers good resiliency

Technical support is good. I can log complaints online through the portal and have engineers in line. I can also take dedicated engineers if needed, although this involves a different support cost. As far as my requirements are concerned, it is working fine. There are two or three types of support. Standard support involves logging a complaint and receiving a call from the OEM on the same day, but hardware replacement takes two to three days. Advanced support offers instant replacement without delays. Hardware support terms include calling or emailing the company or logging the call in the portal to receive remote support, or getting a dedicated engineer or account manager from Dell.

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

"It has good, reliable, fast storage."

"The most valuable feature of this solution is reliability."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"The database workloads are pretty fast because I frequently move data from here to there."

"The latency is good."

"Overall stability is very good. It is a very stable solution."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

More Pure FlashArray X NVMe pros

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

"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."

"It was very easy to install, maintain, and provides excellent manageability."

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

"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."

"The interface is easy to use which makes the product user-friendly."

"It is fast and performs well."

"Connecting it up, you can run it within a few hours."

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 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."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"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."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"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."

"They could add more support for file storage and different types of storage."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

More Pure FlashArray X NVMe cons

"Technical support should respond more quickly because the turnaround time is very high."

"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."

"We had times that we needed a file service solution. We've used FluidFS, but it's a solution that is being transitioned out."

"This product should be a lot more user-friendly."

"There's always room for improvement in the operating code."

"The tool's pricing is high and not suitable for medium companies."

"It would be helpful if the solution offered higher performance, at least on the back end."

"Compellent comes in the form of a component that's not true of a unified storage platform."

More Dell SC Series cons

"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

"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'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."

"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."

"With VMware, we pay $300,000 annually."

"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."

"Our licensing fees are $500,000+ USD."

"The product is expensive."

"As far as the licensing costs, everything is included in the license."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"This product is too expensive compared to others, and I don't see any value in using it."

"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."

"Compared to other solutions out there, it's affordable."

"It is one of the most cost effective systems for us. We have been able to run it longer than most, getting the most benefit and money out of it."

"The pricing is reasonable, but it is expensive."

"It has a good price point and offers some value-added enterprise features."

"This solution could be better priced in comparison with other vendors."

More Dell SC Series pricing and cost advice

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

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