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

"The initial setup was extremely simple and straightforward."

"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."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

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

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

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

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

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

More Everpure FlashArray X NVMe pros

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

"This solution is easy to use."

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

"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 solution is stable; we've had no problems at all."

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

"The flexibility of this solution has been valuable for our business."

"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."

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 the pricing of the product."

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

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"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."

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

"We would like to see VNC integration or be able to use Pure Storage with VNC."

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

"We need better data deduplication."

More Everpure FlashArray X NVMe cons

"In the future, I want any box that comes on-premises to have the provision to integrate with cloud storage."

"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?"

"Dell could improve the upgrading process."

"The connection should be better integrated with the network to offer a better view of the system."

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

"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."

"The price could be improved."

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

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

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

"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."

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

"The licensing is on a yearly basis."

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

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

"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 Everpure FlashArray X NVMe pricing and cost advice

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

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

"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's a very affordable solution."

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

"We have reviewed many platforms over the years. It is probably the best solution for its value."

"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."

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."
