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

"The solution is scalable."

"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."

"It has good, reliable, fast storage."

"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 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 FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"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 standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

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."

"I find this version to be more budget-friendly compared to products from other vendors. This aspect greatly benefits my customers. It's highly advantageous due to its affordability. The operational aspect is also noteworthy. Additionally, its availability and performance are commendable. The speaker are also equally powerful."

"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."

"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."

"The setup is straightforward."

"The product offers good performance and is quite powerful."

"They have a feature called Live Migrate; it's been very, very useful."

"Technical support is very good. I do use it from time to time and it's always excellent."

More Dell SC Series pros

"The solution is useful for machine learning and scientific applications, including computer simulations."

"This has been one of the most reliable storage systems that I have ever used."

Cons

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

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

"Adding some functions to the product would be beneficial."

"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."

"There are some challenges with data encryption and reduction."

"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."

More Pure FlashArray X NVMe cons

"The administration and support (on the way that they delivered) was a little bit slow."

"It's not very efficient anymore. There are better products out there."

"Dell SC Series is no longer available, while Dell PowerStore, which supports NVMe over TCP, is different and not very affordable."

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

"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 could improve the upgrading process."

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

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

"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."

"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."

"The licensing is on a yearly basis."

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

"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."

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

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

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

More Pure FlashArray X NVMe pricing and cost advice

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

"The scalability seems a bit more expensive than even buying a brand new one so far. That has been kind of a drawback."

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

"The pricing of Dell EMC Compellent is competitive."

"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."

"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."

"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."

"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."

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."
